I bought this a three pack of this plant from Bluestone Perennials the autumn before last. They are now 48" tall (twice the height they are supposed to grow) and flopping over. I don't think it is a simple case of mislabeling, because one plant arrived in bad shape, didn't survive the winter, and they sent me a free replacement the next spring. The replacement is now just as tall as the other plants. Next year I plan to pinch them back in late spring in an attempt to prevent the need for staking.

I love this plant. Last year it started blooming in late spring/early summer, and produced tons of flowers. Late in the summer (August), it seemed to be done, so I cut it back to the ground, and within a few weeks, it had started growing back, reaching approximately half the height of the original growth, and it had lots more flowers right into fall. I like how the flower looks like a balloon at first, and then "pops" into a lovely flower, closing to a balloon again at night. Very hardy in the hot NC summer.

Very pretty, shorter variety that I did not need to stake. Be careful with pruning/deadheading. Only remove spent bloom, NOT the entire stalk -- you will remove newly growing buds and greatly decrease flowering time. Avoid moving plant around, its roots do best when left undisturbed. Also, not a good choice around annuals for this reason. VERY long lived once established and low-maintenance. Late emergence in spring, so be sure to mark it well before cutting back. Pretty yellow color for fall foliage.
