Scabiosa, commonly known as Pincushion Flower, is a delightful perennial plant that belongs to the Caprifoliaceae family. These plants are native to Europe, Africa, and Asia. Scabiosa has a remarkably long flowering season, often lasting from early summer well into fall. The name “Pincushion Flower” stems from the distinctive shape of its blossoms, which resemble a cushion filled with pins.
Growing and Caring For Scabiosa
Choosing the Right Location:
Begin by selecting a location with well-drained soil and full to partial sunlight. These plants generally prefer soil that is not overly rich and has good drainage to prevent waterlogged conditions, which can lead to root rot.
Planting Scabiosa:
Plant Scabiosa in the spring or fall, ensuring the soil is workable. Dig a hole slightly larger than the plant’s root ball and place it at the same depth it was in the container. Space multiple Scabiosa plants about 12 to 18 inches apart to allow for proper air circulation. Water thoroughly after planting, and consider adding a layer of organic mulch to retain moisture and suppress weeds.
Watering Needs:
Scabiosa plants have moderate water requirements. Water regularly, especially during dry spells, to moisten the soil. However, be cautious not to overwater, as Scabiosa is susceptible to root diseases in waterlogged conditions. Mulching around the base of the plant helps retain moisture and regulates soil temperature.
Deadheading and Pruning:
Deadhead spent flowers regularly to encourage continuous blooming. This prolongs the flowering period and maintains the plant’s neat appearance. Light pruning in late spring or early summer can help control the plant’s height and shape, promoting a bushier growth habit and preventing it from becoming leggy.
Fertilizing Scabiosa:
Scabiosa is not demanding when it comes to fertilization. A balanced, all-purpose fertilizer applied in early spring can provide the nutrients for healthy growth and abundant blooms. However, avoid excessive fertilization, as Scabiosa performs well in soils that are not overly rich.
Managing Pests and Diseases:
Scabiosa is generally resistant to many pests and diseases, but occasional issues may arise. Look for aphids or spider mites, especially during dry periods. Insecticidal soap or neem oil can help control these pests. Good air circulation and proper spacing can prevent fungal diseases. Regularly inspect the plants for any signs of problems and take prompt action to maintain the overall health of your Scabiosa.
Leaves and Flowers
The leaves of Scabiosa are typically basal, forming a rosette at the base of the plant. They are deeply lobed and often have an attractive, fern-like appearance. The leaves vary in color, ranging from rich green to gray-green, depending on the species and cultivar. Their distinctive texture and form create an appealing contrast against other plants in the garden.
The flowers of Scabiosa are a true highlight, capturing attention with their unique appearance and vibrant colors. The blooms are composed of a central, raised cone surrounded by a fringed disk of petals. The disc is usually dark, ranging from deep purple to black, strikingly contrasting the petals. This distinctive “pincushion” structure gives rise to the plant’s common name. Scabiosa flowers come in various colors, including shades of blue, pink, lavender, white, and even deep burgundy.
Our Selection of Scabiosa
At Martin Garden Center, we bring in varieties in 4″ containers, particularly the Butterfly Blue and Pink Mist hybrids. We have experimented with growing the Black Knight variety and will do so again … wish us luck … and it may be available this spring depending on our success.
We also carry various seed for other varieties not commonly grown by vendors in our area. Many of these are considered annuals but will self-seed. We try, but we do often fail, to stock 4″ Scabiosa from spring through fall, as it will bloom non-stop if deadheaded and trimmed back regularly.
Is Scabiosa Deer Resistant?
Deer tend to avoid plants with aromatic foliage, and the fragrance of Scabiosa act as a natural deterrent, reducing the likelihood of deer browsing on these plants.
Is Scabiosa A Perennial?

How Tall Does Scabiosa Grow?

Dwarf or compact Scabiosa cultivars may stay around 12 to 18 inches tall and are suitable for the front of borders or in containers. Many standard Scabiosa cultivars fall 18 to 24 inches in height, while some taller Scabiosa cultivars can reach heights of 24 to 36 inches (60 to 90 cm) or even more.
