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 the Caucasus Mountains in 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 7 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 ).

'Clive Greaves'
Abundant, large, rich lavender-blue flowers.

'Fama'
Reaches a maximum size of 3 feet x 32 inches, bearing flowers that are deeper blue than the species all summer long.

'Fama Dark Blue'
Similar to 'Fama' but with even deeper blue flowers.

'Floral Queen'
Vigorous with rich lavender-blue flowers.

'Issac House'
Reaches up to 2.5 feet in height, with flowers of various shades of color.

'Kompliment'
Reaches up to 2 feet with large, deep lavender-blue flowers borne on sturdy stems all summer long.

'Miss Willmott'
Tall with creamy-white flowers.

'Moonbeam Blue'
Deep blue flowers.

'Perfecta'
Reaches up to 3 feet with shaggy, blue daisies all summer long.

'Perfecta Alba'
Reaches up to 3.5 feet with shaggy, white daisies all summer long.

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'
Reaches up to 28 inches x 3 feet ( record height 3 feet ) with profuse, lavender-blue flowers, up to 3 inches across, borne from late spring until autumn frosts.
A single plant may bear hundreds of flowers in a season.
Hardy zones 3 to 9

* I'm not a huge fan of groundcover Juniper, especially with Phormopsis Blight and couldn't wait to rip it all out!



After old Juniper ripped out


* after photos taken on Sep 13 2011
Sangria Encore Azaleas, Pocomoke ( dwarf ) Crape Myrtles, Variegated Liriope and everblooming Kalimiris ( Japanese ) Asters add an explosion of multi-season color to the existing Garnet Japanese Maple, Blue Holly Hedge and Globe Blue Spruce that were pruned and saved on this 1985 built home makeover. Along the driveway, I used Globe Cryptomeria as a more exotic looking replacement for a Spider Mite infested Birds Nest Spruce as well as White Drift Roses to show off the red Jap Maple.
