I asked the local plant groups FNPS ( florida native plant society) if they know a native southeast floridean based legume that is fast growing and suitable to use as green fert that will work with the natural rhizobium any one have any ideas of a local i could use to replace any of the layers of permi culture. Ie, ground cover, shrub, or tree.
I am a big fan of the privet cassia (Cassia ligustrina, a.k.a. Senna ligustrina). It is a native, and is rather elegant IMO - the form reminds me of bamboo or ginger. I think I remember reading somewhere that it is not very good at nodulating and fixing nitrogen, but that it is still beneficial when intercropping with other food plants. Undoubtedly does better down south than in Jax, up here it is a die-back perennial at best.
I am working on perennial peanut as a nitrogen fixing ground cover/green mulch. I got cuttings from a friend. I'm in SE FL. I ordered some seeds from the FNPS for beach flower and blanket flower to use as ground cover but I don't know the specifics on what they contribute to the soil. They are native though and attract bees. Have you had any luck?
Have you no shame? Have you no decency? Have you no tiny ad?
