I notice Dobies are selling "Hardy" Amaryllis varieties for planting outside
in pots or borders...

Balentino (red)
Helios (pale yellow)
Swan Lake (white)

BUT are they hardy, or more properly, where are they hardy?

This is fromhttp://www.royalcolors.com/index.php?nav=group_details&select=group_i...

"These hardy and multiplying Amaryllis varieties produces 1-2 stems in
the first year, each with 3-4 flowers from 7-10 cm across. Great to grow
them in containers on your terrace or in groups in your flower beds.
Hardy till -10 deg. C. but you may also choose them to grow and enjoy it
indoors as a plant or as a cut flower."

Hardy to -10°C, eh? Do you believe that, Bob? I don't.

This is an amazing bulb and it performs wonderfully here in central
Texas. I live in Austin and a friend from church gave me a couple of
bulbs about 8 years ago. They have multiplied and I never give them
any special care. They easily survived the 10+ days of freezing
weather (below 20 several days) this past winter and our summers are
often 100+. The person who gave me these called them St. Joseph's
Trumpet (maybe a colloquial reference?).

Yes, quite a few positive comments on that DavesGarden page. But I
remain unconvinced - US states which are much colder than what we
experience here also usually benefit from having an insulating layer of
deep snow. It's also interesting that Hippeastrum x johnsonii was bred
in the UK but has all but disappeared here (there are only 2 UK
suppliers according to the RHS Plantfinder). If it was hardy surely it
would merit a place in gardens here.
