Then in early Spring I noticed my plant was really taking off and lots and lots of BIG blossoms were forming. Until...
read that the blossoms are blue or lilac but as you can see mine are decidedly white with cream/yellow stamens. I'm in love.
Some info and tips on growing this variety:
1. It blooms on old growth but a light pruning after Spring's flowers are spent (mine is still blooming on June 14th here in Portland) may encourage the second bloom in late Summer/early Fall.
2. Mine is growing in a large terracotta pot on the north side of a lattice fence. This situation keeps the roots cool. I gave the plant a good topping of compost in early Spring and plan to do that again in late Summer. Some of the blossoms are on the north side of the fence which gets no direct sun and some are on the south side which gets a lot of sun. My conclusion? This plant can grow happily in at least part shade.
3. I would say the blooming time is 6 weeks in the Spring. Amazing, right? I expect the blooms in late Summer to come in late August or early September and that the flowers to be less blousy like last year.
