Irma brown the tips a little. Came right back with all the rain that followed in the weeks after Irma.

Growth slowed when the dry season hit but it stayed green.

Went 100% dormant in January and was totally brown. Greened back up when all that warm weather came in February. 

I remember a patch of it that grew wild up in Volusia County when I lived in Deland and it had an almost 3 month dormant period up there depending on the weather. I don't expect more than 6 weeks of brown down here in an average winter. Probably need a cover crop mixed in for winter interest if desired. 

Our soil is extremely sandy. We live on the relic sand dune that runs down the west shore of the IRL. I did work in some compost before planting but it is basically growing in sugar sand.
