Perennials Questions
What does perennial mean in Florida?+
A perennial lives for several years, returning season after season; in Zone 9b some die back in cool weather and flush again when it warms.
Do perennials bloom all year in St. Augustine?+
Many perennials bloom in flushes rather than nonstop; mixing species with different bloom times keeps color in the garden longer.
Should I cut perennials back?+
Many perennials benefit from a cutback after a bloom cycle or in late winter to encourage fresh, fuller growth.
When should I plant perennials in St. Augustine?+
Fall and spring are the easiest windows in Zone 9b, giving roots time to establish before the stress of peak summer heat or any winter cold snap.
How do I choose perennials that bloom at different times?+
Combine species with spring, summer, and fall bloom so color rotates through the year. Our team can help you build a sequence for your light and space.
What are the best perennials for full sun in Florida?+
For Florida full sun, dependable perennials include firebush, salvia, lantana, blanket flower, coreopsis, and muhly grass. Choose heat-tolerant species, give them well-drained soil, and group them by water needs.
