Florida Scrub Bluecurls: A Rare Native Gem for Your Garden

Meet Florida scrub bluecurls (Trichostema suffrutescens), one of Florida’s most charming yet lesser-known native wildflowers. This delightful perennial herb might be small in stature, but it packs a big punch when it comes to supporting local ecosystems and adding unique beauty to native gardens.

What Makes Florida Scrub Bluecurls Special?

This native Florida treasure belongs to the mint family and produces clusters of tiny blue to purple flowers that curl in distinctive spirals – hence the bluecurls name. The aromatic foliage releases a pleasant fragrance when brushed against, making it a sensory delight in the garden. As a forb herb, it maintains a low-growing, non-woody form that works beautifully as a ground cover or accent plant.

Where Does It Call Home?

Florida scrub bluecurls is endemic to Florida, meaning you won’t find this special plant growing wild anywhere else in the world. It thrives in the state’s unique scrub habitats, those sandy, well-drained ecosystems that are home to so many of Florida’s rarest plants.
