I think Bill and Nhu are correct, but...

I've spent much of my gardening life trying to grow things that shouldn't
survive in my climate. Most of them are dead, a few have survived, and a
couple have done pretty darned well. You'll never know for sure unless you
try it. So if you want to give it a go, here are the conditions that plant
expects:

In summer (from about May to October in the northern hemisphere) it needs to
be kept dry and cool. Don't totally dry it out as the roots are perennial
and should not dry out completely. A sprinkling once every two weeks is
enough, and the soil should get dry between waterings. Do not leave it out
in the rain! For this reason, pot culture may be best. But you'll need a
very large, deep pot, maybe 40 cm across per bulb if you want it to flower.

In winter, when they grow, keep them moist (I water once a week) and give
them a lot of sunlight. They expect temperatures in the 60s-70s (~20C) in
the day, going down to the 50s or lower at night (5-10C). Lots of air
circulation as well. How humid nights will not be good for them.

Make sure the soil you use is not too dense; in nature they grow in mountain
soil that's mostly coarse quartz sand.

Basically, you're simulating a mediterranean climate, with its summer
drought and cool breezy winters.

If you try it, please let us know how you do!
