Hippeastrum evansiae

Dear all:
A most interesting thread as many regions in which Hippeastrums
were growing wild in South America are totally dedicated to agriculture and
the stock in cultivation is ultra precious now. Evansiae is one of the three
species that has a yellow color of some sort (along with parodii and
aglaiae). Doug's image is of evansiae proper but the red hint is typical of
an ageing flower so is this an indication of some crossing with other
species some time in the past?
Jim Lykos info coincides exactly with the species' conditions in
the wild. A long dry winter (say of zone 10) and then a hot rainy late
spring/summer/autumn season of growth in zone 10/11. Some info can be
misleading to say the least. I am sure there is people that can grow such
bulbs in Minnesota or Saskatchewan but only under the same conditions it has
in its Bolivian habitat.
Interesting information in past issues of Plant Life suggests
that this species is very touchy as to excess watering at any time of its
growth period and in fact it comes from hot dry forests rather than rainy
jungles. It is better to give it Cyrtanthus culture.
Regards
Alberto
