The Yellow Bird of Paradise is a popular evergreen shrub with beautiful yellow flowers.

Learn how to care for them in this guide and how they differ from other flowers, as well as other types of bird of paradise plants.

Yellow Bird of Paradise Overview

This striking plant is an evergreen shrub or small tree that’s botanically known as the Caesalpinia gilliesii, a member of the Fabaceae or Legume family. It’s native to the subtropical regions found in South America, principally Argentina and Uruguay, where it is cultivated as a shrub or small tree.

This plant is also referred to as the Bird of Paradise Bush, the Yellow Bird of Paradise, the Desert Bird of Paradise, and the Barba de Chivo.

Often confused with the Orange Bird of Paradise (Strelitzia reginae), the Yellow Bird of Paradise variety is a separate plant and not related to the Strelitzia genus. Its lovely tropical flowers are characteristically yellow with red stamen.

Because of its love of warm weather, this variety is often seen in the warmer states of the U.S. including the southern states, as well as the western areas of Oklahoma, Nevada, and California. It can grow to a height of six to ten feet and spread to a width of three to eight feet.

Yellow Bird of Paradise

Yellow Bird of Paradise blossoms feature five yellow petals and ten vividly red stamens. Flowers bloom at the end of branch tips during the months of July and August.  

Flowers measure only about an inch in length, but the showy red stamens will be three to four times longer and protrude out of the blossom’s tubular shape.

This shrub also produces fruit that resembles the pods of peas as they are flat and curved, measuring two to five inches long. They are densely covered in reddish, glandular short hairs.

Once pods mature, they open and spew seeds far and wide, so they can be an invasive species.

Fertilizer for the Yellow Bird of Paradise

Yellow Bird of Paradise shrubs can benefit from annual fertilization once they are established, especially during the blooming period.

You can do a soil test to verify if specific nutrients are missing in the soil bed. When feeding, use a standard balanced NPK fertilizer 20-20-20 (nitrogen-phosphorous-potassium).

If you use a fertilizer high in nitrogen, it will encourage green foliage growth, but at the expense of blooms.

Propagating by Seed

Here are the step-by-step instructions on how to propagate and grow the Yellow Bird of Paradise from seed: 

  • Gather plant seeds in autumn from an established plant or acquire them for a garden center or nursery.
  • Place gathered seeds in the sun to dry. Once dried, place them in a sealed glass container and store them in a refrigerator.
  • Six weeks before your area’s final predicted frost, take the seeds out of the fridge and make a small cut or nick the seed coats.
  • Seeds should then be soaked in warm water for 24 hours. Dispose of any seeds that have not sunk to the bottom of the bowl.
  • Prepare a pot or container with an adequate number of drainage holes and fill it with one part of seed starter growing medium and one part perlite
  • Seeds should be placed one-half-inch deep in the seed starter tray and positioned two inches apart. Water lightly.
  • Cover the seed starter tray with plastic. Position it in a location that is warm with a temperature of 75°F to assist in germination.
  • Keep the growing medium consistently moist, but not waterlogged.
  • In one to four weeks, germination should be apparent. Remove the plastic covering and place it in a window with full sun or similar, or under a grow lamp.
  • When the seedlings develop at least four leaves, transplant each into an individual container. Preferably, a peat container that can then be planted directly into your garden bed without further disturbance to the root system.
  • Once the final frost has passed, place your plants outdoors for several hours per day to harden them, gradually increasing the time outdoors a bit every day. When the outdoor exposure increases to at least six hours, transplant them into your garden bed.

Propagating with Soft Wood Cuttings

To propagate the Yellow Bird of Paradise plants with soft wood cuttings, follow these steps: 

  • During the summer, cut six-inch sections of green branches that are still pliable. Use sterilized garden shears. 
  • Fill pots with coarse sand that is kept consistently moist. Dip the tip of each soft wood cutting in rooting hormone and place it into the pot with sand.
  • Cover each pot with loose plastic bags. Fix the bottom of the plastic with a rubber band or tie it around the container.
  • Place the containers in bright indirect sunlight in a warm location.
  • New roots should form on your cuttings in about a month. Tug gently to verify this. If you feel a bit of resistance, the root system is developing.
  • Once the new roots are formed, remove the plastic coverings and continue caring until moving to a permanent pot or placing in the outdoor garden.
