For most of the US, you're completely right about the greenhouse.  In my
particular climate, I can get away with growing them in the open -- they're
in 8" (20 cm) plastic pots, in an area that gets half-shade in summer.  They
are in a very well drained mix (50% peat, 25% sand, 25% perlite).

In summer we get a 5-6 month complete drought with low humidity, so I have
drippers set up to give the pots a bit of water every week.  In a damper
climate, I'm sure the appropriate watering, if any, would be much less

So far I've lost virtually none of the bulbs I received from the rescue,
although some selections offset vigorously while others just sit there.

I have not heard from anyone who's able to make them bloom consistently.
Even the Kirstenbosch folks say they are erratic:…  If anyone has the
magic secret, please speak up.

The holder of the national collection in the UK is Springbank Nursery.
There's a nice article on them, with some detailed cultural advice, here:…

Although they don't have a website, I've heard that they will sell
internationally.  If anyone in the US has a bulb import permit and wants to
try a group purchase, drop me a note...
