The unique tropical plant Strelitzia juncea, which is also called narrow leaf bird of paradise, is beautiful and exotic. It is known for its beautiful flowers and interesting leaves. This perennial plant is native to South Africa and is in the family Strelitziaceae. It can be grown indoors or outdoors all year in warm climates.
With its long slender leaves and vivid orange and bluish blooms resembling a bird’s head it’s easy to see why Strelitzia juncea is such a coveted ornamental plant. Read on to learn all about growing and caring for this spectacular bird of paradise variety.
Overview of Strelitzia Juncea
Strelitzia juncea is a tender perennial plant that grows in clumps and gets 3–4 feet tall and wide. The plant’s leaves are narrow, straight, and rush-like. They are wider when young and turn grassy as they age. The leaves can be up to 20 inches long and only an inch wide.
This plant is nicknamed “narrow leaf” and “rush leaf” bird of paradise due to its slender foliage. As it matures, the leaves reduce significantly in size, leaving just the gray-green leaf sheaths that take on the job of photosynthesis.
The unusual flowers have orange sepals and purple-blue petals that stick out in a way that looks like a bird’s head. If the conditions are right, they bloom in the spring and summer. The flowers are called “bird of paradise” in the Strelitzia genus.
Strelitzia juncea does best in bright, warm environments. It can be grown inside or in tropical gardens outside. It looks tropical and has bright colors, which makes it a beautiful plant for borders and containers.
How to Grow Strelitzia Juncea
When grown indoors, provide Strelitzia juncea with plenty of light from an east or west-facing window. It can tolerate a couple hours of direct morning or evening sun filtered through a sheer curtain. Avoid direct southern exposure as it may scorch the foliage.
Outdoors, plant in a sheltered spot that gets morning sun and afternoon shade. Make sure it’s protected from cold winds and frost which can damage the foliage.
Use a well-draining potting mix and water thoroughly when the top few inches become dry. Too much moisture can lead to root rot. As a tropical plant, Strelitzia juncea also appreciates high humidity. Mist the leaves daily or use a pebble tray for added moisture.
Fertilize monthly during the growing season with a balanced liquid fertilizer diluted to half strength. Feed less often in winter.
Ideal temperatures for Strelitzia juncea are between 65-80°F. Keep away from drafty areas as the foliage can be damaged by cold. In zones 9-11, it can be grown outside year-round. In colder climates, it should be grown in containers that can be moved indoors before frost.
Care and Maintenance
Caring for narrow leaf bird of paradise requires paying close attention to its light, humidity, and watering needs. Here are some tips for keeping your Strelitzia juncea healthy and looking its best:
-
Place in bright, indirect light indoors near an east or west window. Acclimate young plants to avoid leaf scorch.
-
Mist foliage daily to provide the high humidity these tropical plants prefer.
-
Allow the top few inches of soil to dry out between waterings then soak thoroughly. Ensure proper drainage.
-
Feed monthly with a balanced liquid fertilizer during spring through fall. Reduce feeding in winter.
-
Prune off spent flowers and dead or damaged leaves to encourage new growth.
-
Repot every 2-3 years in spring to provide fresh soil and room for root growth.
-
Bring indoors before temperatures drop below 60°F. Protect from drafts and cold near windows or doors.
With the right care, Strelitzia juncea will grow into a spectacular tropical specimen plant known for its architectural shape and vivid color. Pay close attention to its preferences, and this bird of paradise is sure to thrive.
Getting Strelitzia Juncea to Bloom
Mature Strelitzia juncea plants can produce vivid orange and bluish flowers that are sure to grab attention. However, getting these tropical beauties to bloom indoors can be a challenge.
Here are some tips to encourage bird of paradise houseplants to flower:
-
Provide very bright light, ideally 6+ hours of direct sunlight per day. East or west-facing windows are ideal.
-
Allow the soil to dry out between waterings but don’t let it get bone dry. Proper moisture is key.
-
Mist leaves daily and use pebble trays to boost humidity around the plant.
-
Keep temperatures consistently warm, around 70-80°F during the day and above 60°F at night.
-
Feed monthly during spring and summer with a fertilizer high in phosphorus to stimulate blooms.
-
Give the plant a rest period in fall/winter with reduced watering and no fertilizer.
-
Choose a mature, well-established plant that has reached at least 2-3 feet tall. Younger plants may not bloom.
Have patience – it can take Strelitzia juncea 1-2 years to adjust to indoor conditions before flowering. Proper care maximizes your chance of success.
Troubleshooting Common Strelitzia Juncea Problems
While relatively easygoing, Strelitzia juncea can encounter a few issues when grown as houseplants. Here are some common problems and how to fix them:
Leggy growth – If your plant becomes spindly and leggy with wide gaps between leaves, it likely needs more sunlight. Move to a brighter location.
Leaf scorch – Brown crispy edges indicate too much direct sun. Filter the sunlight or move to a shadier spot.
Failure to bloom – Lack of bright light, improper temperatures, or insufficient maturity can prevent flowering. Review care guidelines.
Drooping leaves – Overwatering or underwatering can cause foliage to droop. Check soil moisture and adjust watering habits.
Root rot – Wet soil for too long encourages fungal rot. Repot in fresh mix, remove dead roots, and reduce watering frequency.
Mealybugs – These small sap-sucking pests cause spotting. Wipe away with alcohol or use insecticidal soap sprays.
Catching problems early allows you to correct conditions and get your plant thriving once again. Always review care guidelines when issues pop up.

How to Propagate Strelitzia Juncea
These stunning tropicals can be propagated by division or from seed (if flowering occurs) to create more of these fabulous plants.
Division – The most reliable method is to divide mature clumps when repotting in spring. Gently separate a younger shoot with roots attached and repot in a small container. Keep warm and moist until new growth emerges.
Seeds – If your plant flowers, collect the unique bean-like seeds. Sow seeds in a warm, humid environment in spring. Germination can be erratic and take many months.
Cuttings – Cuttings from stems or leaves have a low success rate with Strelitzia juncea. Division or seeds are better propagation methods.
Take care not to damage the fragile roots when dividing root balls. Allow divisions several months to establish before moving to a permanent pot or garden spot.
Fun Varieties to Grow
Beyond the species, there are some fun varieties of narrow leaf bird of paradise to look for:
-
‘Bubba’ – A dwarf variety growing just 1-2 feet tall, perfect for containers.
-
‘Kirstenbosch’ – Large yellow-orange blooms on a compact, free-flowering plant.
-
‘Moonshine’ – Elegant gray foliage with unique white and pale blue blooms.
-
‘Prince Andrew’ – Dark blue flower bracts on a medium-sized plant.

With its graceful arching leaves and stunning tropical blooms, Strelitzia juncea makes a beautiful addition indoors or out. Though not the easiest houseplant, providing this bird of paradise variety with bright light, humid conditions, and proper care will lead to success. Its striking flowers and architectural shape add drama to any setting.
Giant bird-of-paradise Strelitzia nicolai
This is a much larger plant than Strelitzia reginae, forming huge clumps of stems that can reach 30 feet in height in mature, well-established plants. Its flowers are different as well: the crown of sepals is white or faintly pink, with a blue “tongue” of petals, arising from a dark purplish black bract. One flower spathe sprouts out of another, which gives them a double-decked appearance. From early spring to late summer, the flowers bloom and make a lot of nectar that sunbirds in their native Africa and orioles in the US like.
Narrow-leaved Bird-of-paradise Strelitzia juncea
This is the most drought tolerant of the bird-of-paradise varieties. As it grows in a thick clump, its leaves are very thin and almost reed-like. It makes a beautiful accent plant. The flowers are slightly smaller than those of Strelitzia reginae, but are the same color.
In its native Africa, Strelitzia juncea is only found in six locations along the Eastern Cape, and it is listed as Vulnerable due to quarrying and industrial development, illegal collection for the horticultural trade, and invasive plants. In addition, the number of natural bird pollinators has declined and the plants produce few seeds, further endangering their survival.
