Citizen Science
Lilac chaste tree thrives in hot, dry conditions and produces long lavender flower spikes that draw butterflies and bees through late summer — exactly when most garden shrubs have stopped blooming.
Someone in Sarasota, Florida spotted and documented a Lilac chaste tree growing in their area. This shrub, originally from the Mediterranean, is known for its beautiful purple flower spikes and is increasingly found across the southern US. The observation was verified and accepted as research-grade, meaning it meets the standard needed to contribute to scientific plant records.
