Hippeastrum reticulatum blooms in late summer to autumn, with an active growing season of autumn to early winter, and requires a semi-dormant period of 4–6 weeks during late winter and early spring. The species is unusual amongst Hippeastrum, in being self-fertile. [5] [6]
Amaryllis require a period of dormancy to bloom. This happens naturally for outdoor planted bulbs, but you need to help if your amaryllis is a houseplant. To send the plant into dormancy, remove ...
Amaryllis (/ ˌ æ m ə ˈ r ɪ l ɪ s /) [1] is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae).It is a small genus of flowering bulbs, with two species.The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna.
Dormancy should not be confused with seed coat dormancy, external dormancy, or hardheadedness, which is caused by the presence of a hard seed covering or seed coat that prevents water and oxygen from reaching and activating the embryo. It is a physical barrier to germination, not a true form of dormancy (Quinliven, 1971; Quinliven and Nichol ...
Linnaeus described the type genus Amaryllis, from which the family derives its name, in his Species Plantarum in 1753, [8] with nine species, in the Hexandria monogynia (i.e. six stamens and one pistil) [9] containing 51 genera in total [10] in his sexual classification scheme. The name Amaryllis had been applied to a number of plants over the ...
The term is sometimes used to refer to the need of herbal (non-woody) plants for a period of cold dormancy in order to produce new shoots and leaves, [1] but this usage is discouraged. [2] Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering ...

The dormant or resting period may be in summer or winter, or may depend on rainfall, as in the tropics. [11] The different strategies enable bulbous plants to survive adverse conditions such as extremely hot and dry summers, very cold winters, or periods of drought. [citation needed]
