Where can i get nettles in Florida? I have never seen them grow around here or in any stores, and i am not even sure if they grow much in the US.
What we called "stinging nettles" were the bane of my childhood in northern Florida, but they aren't nettles of the urtica genus. They are actually Cnidoscolus stimulosus, or bullnettle, which unlike true nettles does not have edible leaves, but the small tuberous roots can be eaten cooked like potatoes.
Urtica chamaedryoides, Urtica urens, and Urtica dioica can be found growing wild throughout the state and do have edible leaves.
The US has lots and lots of nettles. From Wiki:
Nettle is part of the English name of many plants with stinging hairs, particularly those of the genus Urtica. It is also part of the name of plants which resemble Urtica species in appearance but do not have stinging hairs.
Plants called "nettle" include:
ball nettle – Solanum carolinense bull nettle Cnidoscolus stimulosus, bull nettle, spurge nettle Cnidoscolus texanus, Texas bull nettle Cnidoscolus urens, bull nettle Solanum elaeagnifolium, bull nettle, silver-leaf nettle, white horse-nettle dead nettle, dumb nettle Lamium, particularly Lamium album false nettle – Boehmeria flame nettle – Coleus hedge nettle – Stachys hemp nettle – Galeopsis horse nettle: Agastache urticifolia – horse-nettle Solanum carolinense – ball-nettle, Carolina horse-nettle Solanum dimidiatum – western horse-nettle, robust horse-nettle Solanum elaeagnifolium – bull nettle, silver-leaf nettle, white horse-nettle Solanum rostratum – horse-nettle nettle tree or tree nettle: Celtis Various species of the genus Dendrocnide Urera baccifera Urtica ferox nilgiri nettle, Himalayan giant nettle - Girardinia diversifolia painted nettle – Coleus blumei rock nettle – Eucnide small-leaved nettle – Dendrocnide photinophylla spurge nettle – Cnidoscolus stinging nettle most, but not all subspecies of Urtica dioica Urtica incisa Urtica ferox tree nettle - see nettle tree white nettle – Lamium album wood nettle - Laportea canadensis
Many of those species are are indigenous to the US.
