Positive | On Mar 6, 2018, noseykate from SOUTH WEYMOUTH, MA wrote: This one takes a prize for longest-blooming flower in the garden. Tolerates heat and dry soil, just keeps blooming until frost stops it. Very pretty - photos don't do it justice - and the bees like to sip. I was worried that it wouldn't be winter hardy but so far it has done fine in zone 6a. I will always want this cultivar in the garden. |
Positive | On Jul 16, 2010, Cheryl_103 from Pittsburgh, PA (Zone 6a) wrote: 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. |

Positive | On May 29, 2009, shelly80504 from Longmont, CO (Zone 5a) wrote: 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. |
Positive | On Aug 6, 2008, cedar18 from Lula, GA (Zone 7b) wrote: 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. |

Positive | On Jun 2, 2005, penpen from North Tonawanda, NY (Zone 6a) wrote: 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. |
Neutral | On Dec 31, 2004, smiln32 from Oklahoma City, OK (Zone 7a) wrote: 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. |
