Planted this in heavy clay soil 2 years ago. It finally bloomed this spring. It just opened 2 days ago- May 24, 2011. It is really pretty. I love the color.

Curious if anyone can give me some pointers. 3 weeks ago I planted some bare root stock of this plant. Before planting I soaked the roots in a warm bath and they sprouted in that few hrs. I also lightly dusted them with rooting hormone. I planted at the prescribed depth. a few are in shade, a few in sun. So far though, not a sign of anything and I'm wondering if I should give up or if there is still hope for them. MN has had a very warm and lovely spring so I figured they would be eager to show.
A beautiful selection with fully double, purplish black, spurless blossoms that resemble small dahlias. This variety was bred especially for cut flower production. It also works well in containers. Attracts butterflies and hummingbirds.
Easily grown from seed. The small, dark double flowers are especially lovely with the pastels of spring blooming plants. Fertilome's Triple Action Plus sprayed a few times early in the season seems to have prevented marring of the foliage from leaf miners. Even when not in bloom, the foliage is very attractive.
