Scrub Morning-glory (Bonamia grandiflora)
It's a stunning sight to see this 8' vine with 3" purple-blue flowers sprawled across the scrub's white sand. Scrub morning-glory once occurred in scrubs throughout much of peninsular Florida, but apparently has gone extinct in many former localities. In south-central Florida it still can be found in a few scrubs on and near the Lake Wales Ridge. But farther north, in Ocala National Forest, scrub morning-glory is actually common along logging roads and in clear-cuts near SR 40 between Lynn and Juniper Springs. Scrub morning-glory maintains large seed banks of dormant seeds in the soil. These germinate quickly after a fire (and apparently after mechanical disturbance such as logging and site preparation). Look for the brilliant blossoms of scrub morning-glory in summer. Scrub morning-glory is federally listed as a Threatened Species.
