Gardeners' Notes:

D. belladonna is on its second year in my garden. Its first season it bloomed beautifully but did need some staking to stay upright. This year it's taking off and the stems look strong and sturdy--I may not need to stake it. I've yet to see buds on it, but we're late this season due to a harsh winter. Foliage growth is very vigorous and healthy.

I have D. belladonna in a small bed near my front porch. It's growing well in clay soil amended with compost. The plant has average water needs and hasn't required any babying other than to get it established last year.

I grow this plant in dryish shade in clay loam with river rock over it. It does fine there if the bugs don't eat it.
