Growing Guide

When to Grow

Valkyrie Purple earns its 10 to 12 inches of space: the dramatic, needle-like petals and deep velvety color read just as well left standing in a border as they do cut for the vase. Sow in spring, 1/8 inch deep, and look for seedlings in 10 to 14 days. Grow in full sun in a 65 to 75 F range. This half-hardy annual is not frost hardy and takes 110 to 120 days from sowing to bloom, so start it early enough in the season to finish, but set plants out only after frost has passed.

How to Sow and Plant

  • Seeds germinate in 10-20 days.
  • Start indoors 4-6 weeks before last frost, or direct seed outdoors after last frost.
  • Ideal germination temperature is 70 F.
  • Special note: When sowing your own saved seed, it is helpful to stratify (cold treat) seeds for 2 weeks before sowing.

How to Grow

  • Prefers full sun to light shade, well-drained soil, and moderate moisture.
  • Space plants to 8-12 inches apart.
  • Plants will not rebloom after cutting.
  • Succession plant every few weeks for continuous blooming.

PESTS/SPECIAL CONSIDERATIONS

Asters can be susceptible to disease and pests.

  • Asters Yellow is a bacteria that is transmitted by leafhoppers. This bacterium has virus-like symptoms and is not treatable, but it can be prevented by covering plants with row cover until bloom time to keep the hoppers off of your plants when they are young and most vulnerable.
  • Rust and Botrytis, aka gray mold, are both caused by excessive moisture at the crown of the plant; avoid this by spacing plants 12 inches apart and keeping the garden weeded to encourage better airflow. Serenade is an organically approved spray that will treat fungal issues such as rust and mold.

How to Save Seeds

  • China asters are insect pollinated; they can become cross-pollinated if not grown in isolation of at least 1/4 mile or caged with bags over the blooms and hand-pollinated to prevent insects from meddling and crossing pollen.
  • Seeds are ready to harvest as soon as they become fuzzy. Cut plants and hang dry over a tarp to catch the seeds.
  • Seeds will remain viable for up to 3 years.
