I have this growing in a very dry summer spot, it does seem to have made many new bulbs not yet flowering, flowers are few, they lay over and are wind damaged. Foliage is like a larger version of the spring crocus. They have been in the ground for 6 years.

I see no reason to give it any other than positive. It's beauty is worthy.
