Frequently asked questions
Which perennial blooms the longest?
Catmint and coreopsis bloom for months when sheared back mid-season.
Does deadheading really help?
Yes — removing spent flowers stops seed production and pushes new blooms.
How do I get color all season?
Combine long bloomers with early (bleeding heart) and late (asters, sedum) perennials.
Do long bloomers need more fertilizer?
A light spring feeding is enough; too much gives leaves instead of flowers.
