>>>> Just how deep does C. x powellii grow in mild climates?

Hi Jim,
I dug an established clump of x powellii, in Plymouth about four years ago,
the clone I call 'Bill Francis', they were just six inches deep. The bulbs
though were 15 inches round, and probably unable to get deeper. It still
took about 1 1/2 hours just to get a couple out the ground without damaging
them.

I planted them at least 15 inches deep and in better soil and I now thing
they're about 2 feet deep at least. Thus depth may relate to how good or how
bad the soil is.

I always plant bulbs deep though, soil temps are more stable and dormancy is
less likely to be affected by short periods of warmer fine weather during
the winter. eg. here if they come up too quick the leaves can easily either
get damaged by late frost or spring gales.

Best Wishes,
Dave
