Hippeastrum evansiae
Origin: Hippeastrum evansiae is native to the Departments of Santa Cruz and Cochabamba of Bolivia.
Habitat: Habitats varied from 200 m - 700 m and from sandy, open plains to accumulations of almost pure peat deposited on the mountain sides. Few growing in full sun but most growing in rather dry forests covering the low eastern foothills of the Andes. The soil is always light and well drained.
Related Species: H. evansiae is closely allied to H. anzaldoi, the latter is native to the Department of Santa Cruz of Bolivia. Some authorities consider that H. evansiae is identical to or a variation of H. anzaldoi.
Varieties/Forms: Hippeastrum evansiae forma virescens is known to exist in cultivation. There are also a wide variety of forms, including some with ‘spidery’ flowers. Bulbs produce 2 – 4 flowers on a spike of pure creamy colour to yellowish with a pinkish throat. Various flower sizes and time of flowering have also been noted on different forms.
Cultivation: My H. evansiae grow happily in well drained sandy soil with at least half of the bulb above soil level. Bulbs enjoy a lot of sunlight. A sandy growing medium and a large pot are recommended for stolons extending from the base of the bulbs. The species goes through a brief rest period during winter time when growth is slow down. It is the time when watering should be withheld. Flowering in spring.
Potential for Breeding: H. evansiae is widely used for cross breeding for the yellowish/creamy colour and shape of its flowers.
