Description
[
edit
]
Species of
Alrawia
grow from bulbs covered with a tunic that is grayish outside and often violet inside. They produce a single flowering stem (
scape
); the
inflorescence
consists of a
raceme
. Individual flowers are borne on a short stalk (
pedicel
) which is turned downwards when the flowers first appear.
[3]
The
tepals
are violet with whitish lobe tips and are joined at the base for up to half their length.
[4]
The pedicels lengthen and turn upwards after flowers are fertilized; the black seeds are globular or ovate.

Cultivation
[

Brian Mathew
describes the species as "enthusiasts' plants", being "not very showy". They are said to be easy to cultivate in a
bulb frame
or
alpine house
but not to increase readily. As they occur naturally in regions with hot dry summers, the bulbs need to be dried out when dormant.
