Perennials and Annuals, Scabiosa Caucasica
Pincushion Flowers are grown from seeds. With a long germination period, we recommend starting them indoors, 4-6 weeks before the last frost in your area.
Note: For indoor starts, we recommend using a heated germination mat, to increase the speed of germination. And, it, results in a higher germination rate.
You can also directly sow seeds outdoors after the danger of frost has passed, and the soil begins to warm. Plant the seeds no more than 1/4″ deep. Then, mark the planting site, as it will take a while for the seeds to sprout.
After 3-4 years, Scabiosa plants should be divided and replanted in the spring. If the plant is not divided, production will dwindle, and the plant will die. Dig up the crown. Cut or break the crown into 3 parts. Then, replant. Or, give some to an appreciative gardening buddy.
Final Plant Spacing: Space plants 12 inches apart.
Days to Germination: Seeds sprout in 10 – 30 days.
Plants are easy to grow. They need little attention during the year. Plants do not like cold or hot, humid weather.
Grow plants in full sun to light shade.
Scabiosa plants like rich, organic, well-drained soil. Ideal soil pH: 6.0 – 7.5.
Mix compost into the planting site, when first planting or when dividing and replanting the crown.
Keep soil moist, not wet. Apply extra water during droughts and hot weather.
Fertilize once in the spring with a general-purpose fertilizer, after plants have begun to grow. Fertilize again in early summer.
Mulch around plants to keep weeds down, and for a neat and tidy appearance.
Deadhead spent blooms as soon as they have died off. This will prompt the plant to produce new blooms all season long.
Ideal Soil pH: 5.0 – 7.5.
Plant Problems – Identify the causes and find the cures.
