Scabiosa

This is a partial listing to include the perennial members of the Scabiosa genus that are commonly used in landscaping. Many of these equal or exceed most annual bedding plants for continuous bloom making them highly valuable. They are also valuable for attracting butterflies. Fast growing, well grown plants may quadruple in size in their second year.
Scabiosa plants are not usually eaten by deer.

Scabiosa alpina ( Dwarf Pincushion Flower )
A low, mounding, rock garden perennial, reaching up to 8 inches x 1 foot.
It is sometimes grown as an edging plants.
The foliage is gray-green and the pincushion flowers are purplish-blue.
The flowers are borne late spring to late summer.
Hardy zones 4 to 9

Scabiosa caucasica ( Caucasian Pincushion Flower )
A semi-evergreen perennial, reaching a maximum size of 40 x 32 inches ( usually much shorter ), that is native to western Asia.
The divided, narrow leaves, up to 6 inches in length, are bright green.
The flat, pale-blue ( with yellowish-green center ) flowers, up to 3.2 inches across, are borne early summer to mid autumn.
Hardy zones 3 to 8 in full sun on well drained soils. It does not like sites that are excessively wet during summer or winter and blooms much better in cool summer climates ( use Scabiosa columbaria cultivars in the southeast U.S. instead ).

Scabiosa columbaria ( Pincushion Flower, Scabiosa )
A perennial, reaching a maximum size of 3 x 3 feet, that is native to Eurasia.
The foliage is gray-green. The basal leaves are usually entire and the stem leaves pinnate. The stems are hairy.
The flowers, up to 3.2 inches across, are light blue with deep purplish central bristles. The flowers attract hummingbirds and butterflies. This is among the longest blooming of all temperate climate perennials, and plants grown in mild climates have been recorded to bloom nearly all year during years where winter only brings light or no frost. In more severe climates, blooming will typically begin during late spring and end with the first hard frost during autum.
Hardy zones 3 to 8 ( use mulch during winter and plant on protected site in zone 3 ) in full sun on light, fertile, well drained soil. Tolerant of drought, soil PH and urban conditions but does not like heavy clay that is poorly drained and wet, especially during winter. This plant is not generally bothered by pests or disease. Generally very easy to grow. Plants are deadheaded ( cutting off finished blooms ) and watered well perform better in terms of continuous bloom. Plants are generally cut back in preparation for winter during late autumn.
Blooming is heavier and plants are most vigorous if plants are fed a 10-10-10 or 15-15-15 during early spring then again during early summer then fed with bonemeal during early autumn to encourage root growth.
Propagation is generally from division. In fact these plants grow most vigorously if divided every 3 years during early spring. You can then supply the entire neighborhood with these cheerful plants.
The cultivars below are excellent as perennial replacements for summer bedding plants. They are also great for containers, for the urban setting or townhouse garden. Often Butterfly Blue and Pink Mist are planted together.

Butterfly Blue

A single plant may bear hundreds of flowers in a season.
Hardy zones 3 to 9

Scabiosa graminifolia
A mat-forming, woody based perennial, reaching a maximum size of 20 x 20 inches, that is native to southern Europe.
The grassy foliage is silvery-gray.
The flowers, up to 2 inches across, are pale purplish-pink.
Hardy zones 4 to 7

Pinkushion
Pink flowers

Scabiosa ochroleuca ( Yellow Scabiosa )
A short-lived perennial reaching a maximum size of 3 x 3 feet, that is native to southern Europe.
The pinnately-lobed leaves are silvery.
The pale-yellow flowers, up to 1.6 inches across, are borne early summer to early autumn. It is recommended to cut back plants during mid July then fertilize again to encourage a strong rebloom which may last until autumn frost.
Hardy zones 4 to 9 in full sun on well drained soil. Propagation is from seed and it often self seeds.

Scabiosa Samanthas Pink
A perennial, reaching a maximum size of 20 inches x 1.5 feet, with a compact mound of gray-green foliage up to 6 inches high.
The large, double, mid-pink flowers, up to 2 inches across are borne late spring to autumn frost. Plants often bloom up to 9 months and sometimes more, in temperate climates.

The pale yellow flowers borne during early summer, sometimes lasting into early autumn. The flowers resemble that of Scabiosa.
