Evelyn, I grow The Giant, such a nice pop of color when the rest of the garden is winding down. They have increased nicely and I've spread them out around the garden. Those I moved to a sunnier location don't flop as badly as those in partial shade. This year I divided a clump of C. cicilicum, which usually blooms several weeks after Giant has finished. I was waiting until early fall to re-plant the bulbs and was reminded to do so by seeing Giant emerge. When I got the box of bulbs off the shelf I found they were already blooming. The site I chose is somewhat rocky, so like you, I planted them a bit shallower than is generally recommended.
