The Perennial Plant Association has awarded the title Perennial Plant of the Year 2000 to Scabiosa columbaria 'Butterfly Blue'.
I love this pale blue little flower it just kinda peeks up at you on it's stem..have been planting these for about 3.5 years now...and yes I can certify them as dog tough...they have been tromped on...watered from the male dog and just in general have been used and abused...and they just keep coming back. As with all perennials give them time to grow in and you will be pleased with the results. I once had a client ask me why perennials always look so weedy....Well....... as Emerson has said "a weed is just an undiscovered plant." Cut them some slack and enjoy the
Let's read what the experts say about this beautiful little plant...............
A member of the Dipsacaceae family, the nearly flat gray-green basal foliage of the pincushion flower hugs the ground. Lacy lavender-blue, two-inch flowers bloom on slender 12- to 15-inch stems from late spring through early fall. Flowering begins in mid-spring with repeated flowering throughout the growing season when consistently deadheaded. In some climates 'Butterfly Blue' flowers until late December. Pincushion flower derives its common name from the stamens which stand above the petals resembling pins stuck in a pincushion. The leaves are hairy, ovate to lance-shaped, with the upper foliage smaller and finely divided creating a mounded rosette six to eight inches high and 12 to 15 inches wide.
Scabiosa columbaria 'Butterfly Blue' can be propagated by stem cuttings. Two-node tip cuttings of soft vegetative growth should be taken before flowering. Cuttings are placed under mist for approximately two weeks with 68F bottom heat. Roots will form in about eight weeks at which time the cuttings can be transplanted to quarts or gallons. After transplanting, quarts should be ready for sale in four to six weeks, and gallons in six to eight weeks. Cuttings taken during the winter should receive a one-percent IBA or KIBA drench to enhance rooting. Botrytis may occur on stem cuttings during cloudy weather.
An excellent cultivar of an old-fashioned favorite, this long-blooming perennial for full sun to light shade grows best in well-drained soil amended with organic matter and a neutral to slightly alkaline pH. 'Butterfly Blue' pincushion flower requires moist soil during the growing season. Very well-drained soil is a requirement for winter survival. This lovely perennial does not appear to be fazed by summer heat and will bloom throughout the growing season when regularly deadheaded. No insect or disease problems have been reported on well-grown, healthy plants. Bare-root plants or divisions should be planted so the emerging buds are just below the soil surface. Container-grown plants can be planted anytime during the growing season 12 to 18 inches apart. The crown of 'Butterfly Blue' should be planted at the depth it was growing in the container to prevent crown rot. It is recommended that the basal foliage not be cut back in the fall. Winter-damaged foliage should be removed in the spring.
