Notes
'King Size Formula' aster (Callistephus chinensis 'King Size Formula') is an annual for borders, cut flowers, and containers. Cool weather suits it, and it can take a light frost. This plant likes full or part sun and average to moist soil of most types. It grows fast and stands erect, so it makes a good tall backdrop. Butterflies and bees visit the blooms.
Pairs well with Supertunia Royal Velvet petunia, Zahara Starlight Rose zinnia, and Red fescue.
