Annual

Florida tasselflower (Emilia fosbergii) is a warm-climate asteraceous annual or short-lived forb with bright orange-red composite flowers on slender stems, naturalized in disturbed sites through much of the humid subtropics and tropics of the Americas and beyond. Young leaves appear in some regional diets when identified correctly—treat eating as a literacy test, not a dare. In gardens it is a quick nectar source for small butterflies and a self-seeding filler in wildflower mixes; in agriculture it is sometimes labeled a weed because it tells the truth about bare soil and irrigation. ☀️💧 Sun and Water Requirements: Full sun; tolerates lean to moderately fertile, well-drained soils. Moderate moisture speeds growth; drought slows flowering. Not frost-hardy—dies back below roughly 30°F (-1°C) without protection. Avoid waterlogged heavy clay that rots the taprooted seedling stage. ✂️ Propagation: Seeds: sow after frost risk; germinates warm in days to weeks. Transplant thinned volunteers into beds where you want controlled color drifts. 🌾 Harvest / Best Use Timing: If using leaves as a pot herb, pick young growth before stems toughen. For pollinator value, leave flowers until seeds mature if you want volunteers; deadhead early if self-sowing is unwelcome.

Good Neighbors
  • Cosmos — similar self-seeding annual energy with complementary flower forms
  • Zinnia — dense annual color that shares sun and pollinators in mixed beds
  • Basil — culinary annual with different chemistry; helps fill space without identical pest profile
Cautions
  • Can behave aggressively in mild frost-free climates—deadhead if you do not want a monologue of orange seedlings
