Know before you buy
You can do both. Starting them indoors is a great way to get a head start on the season, but they also perform well when direct sown once the soil has warmed up.
The key is consistent harvesting. Cutting the stems at the base of the plant encourages the production of new stems and keeps the plant blooming longer.
No, this variety is not recommended for containers. They thrive best when planted directly in the ground with 12 inches of spacing between each plant.
For the longest vase life, harvest the flowers once the petals have fully unfolded. This ensures the bloom is mature enough to hold up well after being cut.
As a hardy annual, 'Prairie Sun' completes its life cycle in one season. While they are winter hardy in zones 5 and south, they will not return the following year like a perennial would.
These plants require full sun to reach their potential. Aim for a spot in your garden that receives at least six to eight hours of direct sunlight daily.
