Strelitzia reginae, also known as crane flower, is native to South Africa and derives its name from the unusual flowers, which resemble brightly colored birds in flight. The plant needs warm temperatures and plenty of sunshine to produce the characteristic blooms.
They are hardy in calid zones, but cooler regions can use them in containers outdoors in summer and move them inside as cooler temps arrive.
Bird of paradise care is not difficult, but the plants do need certain cultural conditions. Strelitzia bird of paradise needs rich soil that is well draining. It blooms most profusely when in full sun, but indoor plants should be slightly away from southern windows to avoid burning. Also, plants grown outdoors in desert climates should be planted in a partial shade situation.
Heliconias grow from a rhizome, which produces shoots, at the top of which the flowers form. The flowers are mostly in reds, yellows, oranges and pinks. What we commonly call the "flower" in a Heliconia is not really the flower at all but a large, showy bract.
The plants range in size from dwarf shade lovers such as Jamaican Dwarf through to towering sun-loving giants over 5m tall such as Richmond Red.
Most varieties flower through summer and autumn, but, of course, there are exceptions. Red Christmas is a dwarf form to about 1m, which flowers from April through to September. It prefers part shade and is a great choice if you want to add colour to a shady garden in winter. It also grows and flowers well in a large pot.
How To Grow The Seeds?
Firstly, loose the soil and then put your seeds in the soil in 0.3-0.5cm of soil, note that do not put them so deep and close in the soil. Secondly, check whether the temperature is fit for sowing these seeds in order to make sure they will grow. Thirdly, water these seeds, but not too often, once or twice a day. Finally, keep the soil moist and make them under the sun. They usually need 15 to 25 days to grow, so please wait patiently!
Soaked in warm water for 8 hours before planting will be better if the seeds is over 0.5mm.
Because the seeds are in dormant state and need to absorb enough water to germination.
