To start with, they began blooming with the early crocuses, and like crocuses, they continue to bloom despite the vagaries of weather, even through the snow. Unlike crocuses which last maybe a week, these have stayed in bloom for at least 6 weeks now, and the first flowers are only just beginning to fade, while new ones form. I expect to see blooms for at least another month. Flowers begin with a purple flush, and the purple stays on the backs of the petals.
Plants stay a compact mound, the peduncles stay short so while you would never pick the blooms for cut flowers, you also don't need to tidy them after bloom, when those flowers turn into puffs of seed. So far they have needed no irrigation since the drink or two I gave them at planting time.
So while these may be boring little daisies in a photo, they are much more enjoyable than I expected. And those Penstemon that I planted to be the stars of the show? They just started blooming, and will be finished in about 10 days. The crocuses are long gone.
