Gardeners' Notes:

I planted this on 3/26/11, it immediately began blooming, with deep purple being the first bloom visible. White was close behind. My plant needs to be watered about every 2 days or it begins to droop. It is in full sun - 9+ hours per day. I am hopeful that the water needs will drop as it gets more established. It is a real show stopper and as of today 4/12/11, it is literally covered in small blooms. Hopefully it will bring in the butterflies when all of the flowers open.

We purchased our shrub online and it was TINY :) Because of family emergencies, we didn't get it planted as we should have and the poor shrub almost died on us. So instead of planting it in the ground, I potted it. I couldn't believe that it actually started to sprout leaves and we even had two shoots of flowers come out of it. The shrub itself is only about 6-8 inches tall even now!
If it can survive our rough handling of it, it can survive anything!
