Is the listed color (red, pink) correct? Haven't planted mine yet, but it was sold to me as purple, and the photos look pretty much purple.

Though in gritty soil that's not too wet, and full sun, this plant seems to easily flop. And the blooms don't seem to last long. I'm trying to decide if it needs staked, or how to better meet it's needs. Rather unattractive (to me) as the flowers start browning from base up. I haven't noticed butteflies yet.

Overall, this plant is stunning when it's in bloom, but rather uninspiring when it's not. The bloom period is not as long as I expected, and I have not had sucess trying to get it to rebloom. It also seems to die out and get woody in the middle, so I've dug it up and divided it every year. I do have to say it's blooming beautifully this year, however.

This plant with it's bright purple long lasting blooms was loved by bees, hummingbirds and butterflies. It was a very bright spot in my garden beginning in early June when there seems to be a lull in blooming plants.

This plant produces tall bright purple tubular blooms in early summer. Plant height is 30 and a spread of 12-18. The foliage is beautiful all year long. Plant it in full sun and in well-drained soil. Medium growth rate. Can tolerate dry conditions. Attracts butterflies and hummingbirds.
