detailed seed-starting info below

Great medium-height perennial. Small rosette of foliage, with flower stalks in summer. Unlike its parents, L. cardinalis and L. siphilitica, this one survives in normal garden positions (without constant moisture), as long as it doesn't get hit by afternoon sun. We've had 'Vedrariensis' (photos above) for a good number of years now – our first plants came from seed, and I've found that it comes true, sporting royal blue to purple flowers. Newer to our garden is 'Ruby Slippers' (photos below), a hybrid of the same parentage, but with deep magenta flowers and more sturdily upright habit. Unfortunately, it lasted only a year.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
