When a girlfriend referred to this flower, she made it sound so common and usual, but I had never heard of it. Scabiosa is a sturdy perennial, that flowers prolifically. As long as I keep it deadheaded, it keeps on going. These flowers are a good filler in a bouquet, yet look just fine alone or in a group, in a vase.
This plant has not multiplied for me, as have so many other perennials. I’m finally deducing it is because I keep the spent flowers removed, so they never have a chance to go to seed. What a trade-off is needed: to let some flowers remain on the plant to go to seed, and then it will flower no more that season. Perhaps it is time for an experiment.
