Scabiosas, also known as pin cushions, are annual flowers that appear in a cream hue in the summer. When planting several scabiosas, expect to see a large bushel of the flowers grow in your garden, with each flower reaching as tall as 60cm. The flowers bloom in summer and up to the first months of autumn, with blooms that are red, blue, purple, white or yellow. The flowers are commonly used as decorative borders for gardens.
Perform a pH test on the soil where you want to plant your scabiosas. You can purchase a pH test kit at your local garden store or can have a lawn specialist perform the test. Scabiosas grow best in fertilized soil that is slightly alkaline with a pH between 7 and 8.
Moisten the soil in your garden and mix in 1 lb. of 2-1-1 fertilizer into your soil. Smooth out the soil and use a rake to get out any rocks or twigs that may be stuck in the soil.
Wash the scabiosa seeds in cool running water and store them in an air-tight container. Place the container in a refrigerator where the temperature can be set to at 20 degrees F. Wait two weeks for the seeds to germinate.
Dig holes in your garden that are at least 1 inch deep and wide, and add two to three seeds for each hole. Space each hole about 30 to 40cm apart.
Cover the holes with the soil that you dug up. Water the soil immediately with 1 cup of water and then continue to moisten the soil 1 inch deep at least once a day. You should see full growth by the middle of summer.
