About Lisianthus
Lisianthus (Eustoma grandiflorum) is a stunning cool-season annual in NE Florida, producing large ruffled blooms resembling roses or peonies in purple, pink, white, and bicolors. Plant from September through early spring for best performance; it cannot survive NE Florida's summer heat but excels as a cool-season bedding or cut-flower plant in zone 9b. Starting at $4.50.

Care essentials
Light
Grow Lisianthus in partial sun (morning sun, afternoon shade); NE Florida's intense direct afternoon sun scorches the foliage and shortens bloom life — a bright, lightly shaded spot is ideal.
Water
Keep soil consistently moist but never waterlogged; well-drained soil is essential. Water at the base to keep foliage dry and reduce fungal issues in NE Florida's humid climate.
Soil & Fertilizer
Grow in well-drained loam or amended sandy soil enriched with organic matter. Apply a balanced slow-release fertilizer at planting; supplement with light liquid feeds during the bloom period. In NE Florida, plant as a cool-season annual from September through spring.
