This is a perennial that will actually bloom all summer. Here in Pittsburgh it starts in late May/early June, and continues until frost. It has slowed down a bit with the extreme heat we've had this month.
Needs good drainage over the winter. I lost three under very heavy snow cover last winter.

Wonderful plant that attracts hummingbirds and butterflies. I have it with Lady in Red Salvia.

Beautiful pink/coral flowers against "waxy looking" dark green foliage. Because these don't really need any attention from me, but still look great and flowers for most of the summer/fall they are one of my personal favorites.

A great plant, it held up better after blooming than nearby P. smallii. I cut it back about 1/3 on June 15 and it's blooming again Aug. 6. The color is a bright pink and looks great with Veronica 'Red Fox.' Foliage still looks very nice.

Seeds germinate best with cold stratification. and a great candidate for winter sowing. I winter sowed my seeds and left the containers outside all winter and every single seed sprouted in spring. Very hardy, drought tolerant and a fast grower once the temps warm up. A great addition to any hummingbird garden.

Plant in a full sun location with well drained soil. It can tolerate drought conditions. Great for zones 5 - 8. Beautiful magenta flowers bloom all summer long. The plant, with flowers, can reach a height of 15". Attracts hummingbirds and butterflies, too. A fast grower.
