Flowering and Fragrance

This Sweet Scabious species blooms 2” inches wide showy flowers on long wiry stems.

The plants bloom time is from late summer into the fall.

While the deep purple or burgundy color of the pincushion-like flowers is widely popular, you will find varieties producing pink and white flower colors.

Light & Temperature

When planting, choose a location getting at least 6 hours of full sunlight in the day.

However, it does well in sheltered areas when planted facing south or west.

The Pincushion Flower plant is one of the longest flowering annuals capable of thriving in USDA zones 9a to 11.

Although the plant is hardy, it does not do well in high heat and humid climates.

Hence, it doesn’t thrive in areas south of USDA hardiness zone 7.

Watering and Feeding

The plant has low maintenance needs and doesn’t need to be watered too frequently.

They are tolerant to drought but don’t do well in high heat and humidity.

So make sure you water the plants occasionally during a particularly hot or dry season.

The Pincushion Flower does tend to flop in very rich soils. Avoid using too much fertilizer too often.

If your garden bed is overly rich, plant the Pincushion Flower near sturdier plants for support.

Soil & Transplanting

Pincushion Flower plants do well in light to medium moisture, so make sure to use a well-drained soil with a neutral pH.

They can do well in chalky, loamy, and sandy soil.

However, avoid using overly rich soils as it can cause the plant to flop over.

If you’re germinating the seeds indoors, do it in peat pots or cell packs.

Transplant them only when the roots have been established.

Plant them about 9” inches apart from each other in well-drained soil.

Keep the soil moist in the beginning, but don’t overwater as root rot may occur.

Grooming and Maintenance

The best part about planting Pincushion Flower is it’s very low-maintenance.

The only pruning you need to do is cut back after flowering to promote future blooming.

Deadheading the spent flowers to prolong additional bloom.

However, leaving them in place is very attractive.
