Gardeners' Notes:

I planted this in the wrong spot the first year and nearly killed it (needs lots of sun)
The next year I moved it with no adverse effect. The plant came back and flowered very heavily. The flower color is bright and I was pleased when they stayed on for a few of weeks. It got a bit of powdery mildew toward the end of the year.

Northwest Ohio -
This plant is a stand alone plant that I put on the side of my house where the sun shines about 4-5 hours a day in mid summer. It bloomed extremely hard after the first week of September and continued for about 2-1/2 weeks. This plant does seem to move fast, which is good if you have the room, because even a 3-4 inch new stem will flower. I watered this plant twice a week in a well drained area. Towards the end of summer when it's ready to flower and especially while flowering, it may be necessary to stake this plant to hold it together. However, in doing so, brings a much fuller bloom!

Kind of invasive but hard to come back if you divide or move it. Flowers seem to fall forward easily and need support.
