There are two species commonly known as white strelitzia: the Giant White Bird of Paradise (\(Strelitzianicolai\)) and the more compact White Bird of Paradise (\(Strelitziaalba\)). Both are native to South Africa and are distinguished from the more familiar orange-flowering species by their large, lush foliage and different flower coloration.
Giant White Bird of Paradise (\(Strelitzianicolai\)) Size: This species is significantly larger, growing up to 30 feet tall and wide in outdoor environments. Indoors, it typically grows 6 to 8 feet tall.Flowers: The striking, bird-shaped flowers are composed of white sepals and blue petals, emerging from a purplish-gray, beak-like spathe.Foliage: It features very large, banana-like leaves that are dark green and arranged in a fan shape. As the leaves age, they naturally tear, resembling giant feathers.Growth habit: It is a clumping evergreen perennial that forms a woody, banana-like trunk over time.Use: Often used as a dramatic specimen plant in warm climates or as a large, architectural houseplant.
To grow a white strelitzia plant from seed, first remove the orange fuzz and soak the seeds for 24 hours. Next, lightly scarify the seed coat and plant it about \(1/2\) to 1 inch deep in a well-draining potting mix, keeping it warm and consistently moist. Be patient, as germination can take several months, and flowering can take up to 10 years. Step 1: Prepare the seeds Remove fuzz: Gently pull or rub off the bright orange "fuzz" or aril from the black seeds.Soak: Submerge the seeds in lukewarm water for 24 to 48 hours to soften the hard outer coat.Scarify: Lightly nick the seed coat with a knife or sand it with sandpaper. This creates a small opening, helping water penetrate and speeding up germination. Step 2: Plant the seeds Choose a pot: Select a pot with drainage holes and a well-draining potting mix. You can use a heat mat to maintain warmth.Plant: Sow the seeds about \(1/2\) to 1 inch deep, placing them at least 3 inches apart if planting multiple seeds.Cover: Lightly cover the seeds with the soil mix. You can place a plastic bag or a cloche over the container to create a humid environment, but ensure the soil remains moist, not waterlogged.
