Mystery Plant in North Central Florida: Possibly Spanish Needles

Three plants with opposite leaves and a single yellow terminal flower (not a cluster) appeared in a North Central Florida yard.

Expert's Thoughts

• First photo resembles **Spanish needles (Bidens alba)** after ray petals drop.
• Second photo looks different—possibly herbicide damage?
• Parsley family includes **toxic members** (poison hemlock, hog parsley)—**do not taste**.

Recommendation

Wait for more blooms and resend photos, or take a sample to a **local nursery** for in-person ID. Florida's year-round growth means huge species diversity.
