Fern-like, light green foliage, and very nice reddish-pink blooms in June.
Height with flower stems is about 30". We grow this in full sun.
The long flower stems get floppy in our experience, and we usually put a tomato cage around them to keep everything upright. Floppy is a real problem with this plant when it is grown in partial shade, as the flower stems will then grow horizontally, and the plant becomes a bit of a mess.
Hardy to zone 2.
Glen's score: 7.
