About Florida Arrowroot
Zamia floridana · also called Florida Arrowroot, Coontie Palm · houseplant
Florida Arrowroot is the only cycad native to the continental United States, found in Florida's sandy scrub and pine flatwoods. Its stiff, dark-green pinnate fronds emerge from a mostly subterranean trunk. Although historically used for food starch after detoxification, all parts are severely toxic to pets and humans if ingested without processing.
Preferred mix: Sandy, sharply draining mix
Watch for — Overwatering and crown rot: The most common cause of death indoors. If the central crown becomes soft or the base turns brown and mushy, the plant is rotting. Remove from pot, cut away rotten tissue, dust with fungicide, and allow to dry for several days before repotting in fresh dry sandy mix.
Why florida arrowroot needs this mix
Florida Arrowroot is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Florida Arrowroot is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons florida arrowroot struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates florida arrowroot's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for florida arrowroot.
