I. cycloglossa grows, flowers beautifully, increases, and most years also
sets seed here in SE PA.  Mine are in pure sand but any well drained compost
is OK.  They are unprotected year round and fed with maybe one liquid feed
through the hose in the spring, and a good dose of bone meal in the fall. I
lift, divide and replant every three years or so - but be careful as the
storage roots are extremely easy to detach from the bulbs.
