Whether you are planting your very first flower garden or adding another favorite to an established landscape, orange nasturtiums are an excellent choice. This complete growing guide will show you everything you need to know about planting, growing, and caring for these vibrant edible flowers so you can enjoy a garden filled with color all season long.
What Is an Orange Nasturtium?
Orange nasturtiums are flowering annuals belonging to the Tropaeolum genus, a group of plants native to the cool mountain regions of South America. Today, they are grown around the world for their colorful blooms, attractive foliage, and exceptional versatility.
Their distinctive round leaves resemble tiny green lily pads, creating an attractive backdrop for the bright orange blossoms that rise above the foliage or trail gracefully along the ground. Depending on the variety, plants may form compact mounds, spread as colorful ground covers, or climb several feet up fences, arches, and trellises.
Unlike many ornamental flowers, every above-ground part of the nasturtium plant is edible. The flowers, leaves, stems, and even immature seed pods can all be enjoyed in the kitchen, making orange nasturtiums one of the few plants that are equally at home in ornamental and edible gardens.
Why Gardeners Love Orange Nasturtiums
Orange nasturtiums offer an impressive combination of beauty, practicality, and ease of care that makes them one of the most popular annual flowers for home gardens.
Their brilliant orange blooms instantly brighten any landscape, pairing beautifully with purple salvias, blue lobelia, white alyssum, yellow marigolds, and green vegetable foliage. Whether planted alone or mixed with other annuals, they create a vibrant display that draws attention throughout the growing season.
Gardeners also appreciate how quickly these flowers grow. Seeds germinate rapidly, and plants soon begin producing lush foliage followed by an abundance of blossoms that continue until cool autumn weather arrives.
Another reason orange nasturtiums are so popular is their ability to attract beneficial wildlife. Their nectar-rich flowers provide an excellent food source for bees, butterflies, and hummingbirds, helping support healthy pollinator populations that benefit the entire garden.
Vegetable gardeners especially value nasturtiums because they often function as companion plants. They can attract aphids away from vegetables, making them useful trap crops while simultaneously inviting beneficial insects that naturally help maintain garden balance.
Their edible flowers also make everyday meals feel a little more special. Toss them into fresh salads, decorate cakes, garnish soups, or use them to brighten charcuterie boards with their vivid color and peppery flavor.
Botanical Information
Orange nasturtiums belong to the family Tropaeolaceae and are most commonly grown as annuals throughout North America.
The plants produce soft, rounded leaves attached near the center, giving them a distinctive umbrella-like appearance. Their trumpet-shaped flowers feature five overlapping petals and a long nectar spur that attracts hummingbirds and numerous pollinating insects.
Depending on the cultivar, mature plants typically grow between 10 inches and 10 feet long. Compact bush varieties remain neat and tidy in containers, while trailing and climbing types create cascading displays or quickly cover vertical supports.
The flowers bloom continuously throughout the growing season, producing fresh blossoms almost daily under favorable conditions.

Popular Orange Nasturtium Varieties
Choosing the right variety allows you to enjoy orange nasturtiums in nearly any garden setting.
Alaska Orange features striking orange blooms that contrast beautifully with creamy white and green variegated foliage. This variety adds interest even when flowers are temporarily between bloom cycles.
Jewel Orange is a compact, bushy variety producing large semi-double blossoms that make excellent additions to borders, containers, and raised beds.
Orange Gleam develops long trailing stems that spill elegantly from hanging baskets, retaining walls, and elevated planters.
Phoenix Orange offers uniquely fringed petals that give each flower a dramatic, feathery appearance unlike traditional nasturtiums.
Tall Orange climbing varieties produce vigorous vines capable of covering trellises, fences, pergolas, and arches with brilliant orange blooms throughout the season.
The Best Growing Conditions for Orange Nasturtiums
One of the greatest strengths of orange nasturtiums is their adaptability. They grow successfully in many climates and soil types, making them an ideal flower for gardeners who want reliable results without complicated care routines.
Unlike many flowering plants that require rich soil and regular feeding, nasturtiums actually bloom more abundantly when grown in average or slightly poor soil. Too much fertilizer encourages leafy growth while reducing flower production.
Providing plenty of sunshine, well-drained soil, and moderate watering will reward you with vigorous plants covered in colorful blossoms for months.
USDA Hardiness Zones
Orange nasturtiums are grown as annuals throughout USDA Hardiness Zones 2 through 11.
Gardeners in colder climates typically sow seeds outdoors after the last spring frost once the soil has warmed.
In warmer southern regions, many gardeners plant seeds during autumn or winter to enjoy flowers during the cooler months before summer heat arrives.
Their rapid growth means even northern gardens can enjoy a full season of continuous blooms.
Sunlight Requirements
For the most spectacular floral display, plant orange nasturtiums where they receive six to eight hours of direct sunlight each day.
Full sun encourages compact plants and continuous flowering throughout the growing season.
If you live in an area with extremely hot summers, providing light afternoon shade helps protect plants from excessive heat while still allowing plenty of blooms.
Too much shade causes plants to produce abundant foliage with significantly fewer flowers.
Temperature and Humidity
Orange nasturtiums perform best when daytime temperatures remain between 55 and 75 °F.
Cool mornings and mild afternoons encourage vigorous growth and steady flowering.
When temperatures climb above 85 °F, blooming may temporarily slow as plants conserve energy. Fortunately, flowering usually resumes once cooler weather returns.
Because the plants prefer moderate humidity and good airflow, avoid overcrowding to reduce the chance of fungal diseases.
Best Soil for Orange Nasturtiums
Well-drained soil is the foundation of healthy orange nasturtiums.
These adaptable flowers thrive in sandy, loamy, or average garden soil with a pH between 6.0 and 7.5.
Resist the temptation to enrich the soil with excessive compost or high-nitrogen fertilizer. While rich soil produces lush green leaves, it often comes at the expense of flowers.
If your garden contains heavy clay, improve drainage by incorporating organic matter and coarse sand before planting.
Orange nasturtiums prove that beautiful gardens do not have to be complicated. With plenty of sunshine, well-drained soil, and only modest care, these cheerful edible flowers will reward you with months of brilliant blooms, beneficial pollinators, and colorful harvests that are as enjoyable in the kitchen as they are in the garden.
Orange Nasturtium Growing Guide: How to Grow Vibrant Edible Flowers That Brighten Every Garden
How to Plant Orange Nasturtiums
Orange nasturtiums are one of the easiest flowers to grow from seed, making them a favorite for both beginning and experienced gardeners. Their fast germination and vigorous growth mean you can enjoy lush foliage and vibrant blooms in just a few weeks.
Unlike many flowering annuals, nasturtiums do not like having their roots disturbed. For the healthiest plants, sow seeds directly in the garden whenever possible. If you need to start seeds indoors because of a short growing season, use biodegradable pots that can be planted directly into the soil to minimize transplant shock.
Before planting, soak the seeds in room-temperature water for 8 to 12 hours. This softens the hard seed coat and often speeds up germination.
Plant seeds about ½ inch deep and space them 10 to 12 inches apart for bush varieties. Climbing and trailing varieties benefit from 12 to 18 inches of spacing, giving their vines plenty of room to spread naturally.
Keep the soil evenly moist until seedlings emerge, which usually takes 7 to 14 days depending on soil temperature.
Growing Orange Nasturtiums in Containers
Orange nasturtiums thrive in containers and are perfect for patios, balconies, porches, and small-space gardens. Their colorful blooms spill beautifully over the edges of pots, creating a lush display that lasts all season.
Choose a container with drainage holes to prevent excess moisture from collecting around the roots. A pot that is at least 10 to 12 inches wide gives the roots enough room to develop while supporting healthy flowering.
Fill the container with a high-quality potting mix that drains well. Avoid overly rich mixes that contain excessive fertilizer, as this encourages leafy growth rather than flowers.
Place the container in a sunny location where it receives at least six hours of direct sunlight each day. During periods of intense summer heat, containers may need watering more frequently than garden plants since potting soil dries out faster.
Trailing varieties look especially stunning in hanging baskets and elevated planters where their vines can cascade several feet over the sides.
Growing Orange Nasturtiums Indoors
Although orange nasturtiums are most commonly grown outdoors, they can also brighten sunny indoor spaces.
Place containers near a south-facing or west-facing window where plants receive abundant natural light. If sunlight is limited, supplement with full-spectrum grow lights for 12 to 14 hours daily.
Indoor plants appreciate good air circulation and moderate temperatures between 60 and 70 °F. Avoid placing them near heating vents or air conditioners that create sudden temperature changes.
Because indoor conditions often reduce pollinator activity, gently brushing the flowers with a small paintbrush can help transfer pollen if seed production is desired.
Watering Orange Nasturtiums
One of the biggest mistakes gardeners make is overwatering nasturtiums.
These plants prefer moderate moisture rather than constantly wet soil. Once established, they tolerate short periods of dry weather surprisingly well.
Water deeply when the top inch of soil feels dry. This encourages roots to grow deeper into the soil, making plants more resilient during warm weather.
Morning watering is ideal because it allows leaves to dry throughout the day, helping reduce fungal problems.
Container-grown plants generally require more frequent watering than those planted in garden beds, especially during hot summer weather.
Signs that your nasturtiums need water include slightly drooping leaves during the morning or dry soil several inches below the surface.
Fertilizing Orange Nasturtiums
When it comes to fertilizing orange nasturtiums, less truly is more.
Rich soil and heavy feeding often produce large, lush plants with surprisingly few flowers. In fact, many gardeners find that the most spectacular blooming occurs in average garden soil with little or no supplemental fertilizer.
If plants appear unusually pale or are growing in extremely poor soil, apply a diluted balanced fertilizer once early in the season. After that, allow the plants to grow naturally.
Avoid fertilizers high in nitrogen, which encourage abundant foliage while reducing flower production.
For most home gardens, healthy soil and proper watering provide everything orange nasturtiums need to thrive.
Pruning and Deadheading
Regular pruning keeps orange nasturtiums looking fresh and blooming continuously.
Remove faded flowers before they begin producing seeds. This simple task encourages the plant to direct its energy toward producing new blossoms instead of seed development.
Trim away yellowing, damaged, or overcrowded stems to improve air circulation and reduce the risk of disease.
Trailing varieties may occasionally become tangled or overgrown. Light trimming helps maintain a fuller appearance while encouraging branching and additional flowers.
Throughout the season, harvesting flowers and leaves for the kitchen naturally acts as gentle pruning, stimulating even more growth.
How to Propagate Orange Nasturtiums
The easiest way to propagate orange nasturtiums is by saving their seeds.
After flowers fade naturally, large wrinkled green seed pods begin to develop. Allow these seeds to mature and dry on the plant until they become tan or light brown.
Collect the dried seeds before heavy rain or frost arrives.
Store them in a cool, dry location inside labeled paper envelopes or airtight containers until the next planting season.
Because nasturtiums readily self-seed in favorable climates, you may discover new seedlings appearing naturally the following spring.
Some gardeners simply allow a few seed pods to remain on the plant each year, creating a beautiful cycle of volunteer flowers with little effort.
Companion Planting with Orange Nasturtiums
Orange nasturtiums are among the most valuable companion plants in the vegetable garden.
Their bright flowers attract bees and butterflies that improve pollination for nearby crops while also inviting beneficial insects that prey on common garden pests.
Many gardeners plant orange nasturtiums near tomatoes, cucumbers, squash, pumpkins, beans, broccoli, cabbage, kale, peppers, and fruit trees.
Their colorful blooms often attract aphids away from vegetables, acting as sacrificial trap crops that help reduce pest pressure on valuable plants.
The low-growing foliage also helps shade the soil, reducing moisture loss and suppressing weeds around neighboring crops.
Beyond their practical benefits, orange blossoms create beautiful color combinations alongside vegetables, herbs, and flowering annuals.
Common Pests
Orange nasturtiums are generally easy to grow, but several insects occasionally visit the plants.
Aphids are perhaps the most common pest. Fortunately, they often gather on nasturtiums instead of nearby vegetables, making the flowers useful trap plants.
Whiteflies may appear during warm weather, particularly in areas with limited air circulation.
Spider mites occasionally develop during prolonged hot, dry conditions.
Caterpillars sometimes feed on the leaves, leaving small holes behind.
Japanese beetles may also visit in certain regions.
Most infestations remain minor and can be managed with a strong spray of water, hand removal, or encouraging beneficial insects such as ladybugs and lacewings.
Common Diseases
Orange nasturtiums experience relatively few disease problems when grown under proper conditions.
Powdery mildew may appear during humid weather, producing a white coating on leaves.
Root rot can develop if soil remains consistently wet or poorly drained.
Leaf spot occasionally appears following extended periods of rain or overhead watering.
Most disease issues can be prevented by providing good air circulation, watering at the base of the plant, avoiding overcrowding, and growing nasturtiums in well-drained soil.
Removing damaged foliage promptly also helps maintain healthy plants throughout the growing season.
Common Growing Mistakes
Even though orange nasturtiums are easy to grow, avoiding a few common mistakes will help you enjoy even more flowers.
Planting in overly rich soil often produces lush green leaves but disappointingly few blooms.
Applying too much fertilizer has the same effect, encouraging foliage instead of flowers.
Growing plants in too much shade significantly reduces blooming.
Overwatering can lead to root problems and weak growth.
Crowding plants too closely together limits airflow, increasing the chance of fungal diseases.
Starting seeds too early indoors may result in transplant shock since nasturtiums dislike root disturbance.
Removing spent flowers regularly and providing plenty of sunshine are two of the simplest ways to keep plants blooming continuously from spring through fall.
With proper planting, moderate watering, and only minimal maintenance, orange nasturtiums reward gardeners with an abundance of cheerful blooms that attract pollinators, enhance vegetable gardens, and provide delicious edible flowers throughout the growing season.
Harvesting Orange Nasturtiums
One of the most rewarding parts of growing orange nasturtiums is enjoying a harvest that is both beautiful and delicious. Unlike many flowering plants that are grown strictly for ornamental value, nasturtiums produce edible flowers, leaves, stems, and immature seed pods, making them one of the most versatile plants in the garden.
Harvest flowers once they are fully open for the best color and flavor. The ideal time to pick them is early in the morning after the dew has dried but before the afternoon heat arrives. Freshly harvested blossoms are crisp, vibrant, and ready to brighten everything from salads to desserts.
Young leaves are the most tender and have a pleasantly peppery taste similar to arugula or watercress. Older leaves are still edible but have a stronger flavor that works well in cooked dishes or homemade pesto.
The immature green seed pods can also be harvested before they harden. When pickled, they develop a tangy flavor that closely resembles traditional capers, making them a favorite among home gardeners looking to reduce food waste.
Frequent harvesting encourages the plant to continue producing new flowers, giving you an even longer blooming season.
How to Store Orange Nasturtiums
Fresh orange nasturtiums are best enjoyed shortly after harvesting, but proper storage helps preserve their quality.
Place freshly picked flowers in a shallow airtight container lined with a slightly damp paper towel. Store them in the refrigerator where they will remain fresh for one to three days.
Leaves can be stored the same way and are best used within a few days for maximum flavor and texture.
If you are collecting seeds for next year’s garden, allow them to dry completely on the plant before harvesting. Once dry, store them in labeled paper envelopes or airtight containers in a cool, dry, dark location. Properly stored seeds often remain viable for several years.
Avoid storing flowers alongside apples, bananas, or other fruits that release ethylene gas, as this can shorten their freshness.
Preserving Orange Nasturtiums
There are several creative ways to preserve orange nasturtiums so you can enjoy them long after the growing season ends.
Freeze edible flowers inside ice cubes to add a colorful touch to lemonade, iced tea, sparkling water, or festive beverages.
Blend the leaves into pesto and freeze it in small portions for quick meals throughout the year.
Pickle immature seed pods with vinegar, garlic, herbs, and spices to create a flavorful homemade caper alternative.
Infuse flowers into vinegar or olive oil for colorful homemade dressings and marinades.
For special occasions, crystallize fresh blossoms with egg white and superfine sugar to decorate cakes, cupcakes, cookies, and pastries.
These simple preservation methods allow you to enjoy the beauty and flavor of orange nasturtiums well beyond the growing season.
