Growing Guide

When to Grow

Plant Valkyrie White in spring for crisp, snow-white quilled blooms, and give it full sun from the start. Sow the seed 1/8 inch deep; it germinates in 10 to 14 days. Space plants 10 to 12 inches apart, in a site that stays within their preferred 65 to 75°F growing range. This annual is not frost hardy and takes 110 to 120 days to mature, so get it going early enough in the season to finish.

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.

FAQ

How much sun does Valkyrie White need?

Full sun. It is a medium-height annual grown for spring planting in cool-season conditions.

Is Valkyrie White a good aster for white bouquets?

Yes. The snow-white, elegantly quilled blooms are a standout from the Valkyrie series, with the long vase life and strong stems the series is known for, and they also work as a clean contrast against bolder colors.

My seed has not come up yet. How long should I wait?

Give it the full 10 to 14 days. Check that the seed is no deeper than 1/8 inch, since it is sown shallow.
