Guy:

Thank you for the input; I had wondered
if buried Urginea bulbs did not receive sufficient summer
heat to bloom.  However, that is not normally a problem
in Yuma; the ground does not insulate here like it does
elsewhere in the Southwest.  Wherever the summer sun
touches it, temperatures are oven-hot down to at least a
foot.  I lost many bulbs because of this when I first
moved here.

Dear Shawn,

300 bulbs of Urginea maritima
are blooming now around my olive farm
in southern Catalonia
(Spain) in a very dry Mediterranean
climate. They were
already here when I bought the old
farm, probably for a very
long time, they have naturalised
on and on, and they still do so.
Most of them have the neck at
ground level, some are a bit out and
some a bit deeper in
the dry leaves. They all bloom well,
maybe better if they
have a long and dry summer rest and a
bake.

Maybe if they are too deep, they
do not get enough heat to bloom?
For
Amaryllis belladonna, only one
blooming now, maybe mine are also too
deep or too dry in
winter?
Hope it may help you
