Those species both come from summer-dry desert areas where you'd expect them
to have a long dormancy (think inland southern California or Libya). So they
shouldn't be growing after only a short dormancy.

However, I've never had much luck trying to force a confused bulb back into
dormancy, so if they're trying to grow, I'd water them, keep them in a shady
spot where they won't get too hot in summer, and see what happens. Hopefully
they'll eventually re-synchronize with the seasons.

Be careful with the Daubenyas in dormancy. They have thin papery skins and
seem to dessicate easily when out of the ground. I've damaged some by
storing them out of pots for a couple of months in summer. I think it's best
to store them in the pots in a dry location -- when they finally do go

Good luck!
