Best grown in light, medium moisture, well-drained soils with a neutral pH in full sun. Good drainage is the key to growing this plant well. Allow soils to dry between waterings. Plants tend to rot in wet, poorly drained soils. Particularly intolerant of wet soils in winter, and benefits from a light, dry winter mulch. Best performance is in cool summer climates such as the Pacific Northwest. Plants are generally intolerant of high heat and humidity, and do not grow well in the deep South (south of USDA Zone 7). Remove spent flowers to encourage additional bloom.

Noteworthy Characteristics

Scabiosa, commonly called pincushion flower, is a genus of about 80 species of annuals, biennials and perennials primarily from the Mediterranean region but also from other parts of Europe, the Caucasus, Africa, Asia and Japan.

The genus name Scabiosa comes from the Latin scabies meaning the itch in reference to the plant's rough leaves which could supposedly cure scurvy.

‘Giant Blue’ typically grows to 18” (less frequently to 24”) tall with a similar spread. It is similar in appearance to S. ‘Butterfly Blue’, but features larger flowers and a reportedly more vigorous growth habit. This is a clump-forming perennial that blooms continuously from May to frost. Lavender-blue flowers (to 3” diameter) bloom singly on strong stiff stems. Each flower features an outer ring of frilly, flat, lavender-blue petals and a domed, lavender-blue center cushion with distinctively protruding stamens. The center cushion of each flower resembles a pin cushion full of pins, hence the common name. Grayish-green foliage features entire, lance-shaped, basal leaves and pinnately-lobed stem leaves.


No serious insect or disease problems. Must have well-drained soil to thrive. Watch for aphids and whiteflies. Powdery mildew may occur.
