Gardeners' Notes:

Neutral coriaceous On Apr 11, 2014, coriaceous from ROSLINDALE, MA wrote:

This is the colchicum most commonly encountered in the stores, here in the US. It's far from my favorite, but it's still a good garden plant, one of the most floriferous. It's also the quickest to flop. Growing it through a low groundcover will help hold it upright.

I prefer cultivars with wider segments and deeper color. 'The Giant' is widely offered, and more to my taste. It's also sturdier.

I planted some Lilac Wonder Colchicums last year, and they were absolutely beautiful. I think Colchicums are really under-appreciated. They bring a lot of color to the Fall garden. Colchicums can be more expensive than other types of bulbs, but they are definitely worth it. And the bulbs are large, so you get several flowers per bulb.

This is one of my favorites of the group of garden cultivars produced in Holland in the early 1900's. It has waxy deep lilac flowers with just a ghost of tessellation on tall perianth tubes ("stems"), they make good cut flowers too. They do tend to fall over after a day or two outside, but still look good when flopped! Inceases very well here in St John's Newfoundland; I lift and replant every two to three years
