| Florida betony develops ridged tubers that look sorta like a rattlesnake tail and are edible. |
Florida betony (Stachys floridana) is an aggressive perennial wildflower. Most botanists think that it was originally endemic to Florida, but now has spread to most of the Southeastern states from Virginia to Texas. It's a member of the mint family (Lamiaceae) and has the typical square stems and opposite leaves along the stems. The beautiful bilateral flowers range from whitish to purple arranged on a spike. It does best in damp soils.
The tubers are edible
It's also known rattlesnake weed because of its rattle-like tuber. Florida betony tubers are edible when harvested in the spring when they are firm and white, but only if the area has not been poisoned with lawn-care chemicals. They have the crispness of a water chestnut with a taste reminiscent of a very mild radish. Most people don't eat them later in the season when they turn tan or yellow and are not as crisp.
