Encephalartos cold hardiness ?

Featured Replies

hello,

I' m waiting for some seeds of Encephalartos wich come from one supplier in Europe.

My order is :

Encephalartos middelburgensis

E lehmannii

E princeps

E longifolius

E lanatus

E dolomiticus

E cycadifolius

Do you Know the cold hardiness of these species?

I've got some success with one specie, Encephalartos fredericii guiliemii, in the ground since 4 years without problem I'm in zone 9a/8b in France (it has taken -8° c with no damage)

I hope it would be ok with one or two species of my list;

Hi sapida,

Very nice freddie g. It looks very happy.

I think generally the blue encephalartos are fairly cold hardy. I have E. princeps, lehmannii, horridus, lanatus, longifolius blue, and trispinosus that were unscathed by 27F and numerous light frosts. My lehmannii threw a new set of leaves right through the worst of it (with the frost), and the leaves were untouched and hardened without any scarring as spring hit.

Also my green Encephalartos went untouched which include E. longifolius, natalensis, altensteinii, arenarius. Just for the info none of my Dioons were hurt either. The only thing in my yard that showed some burn was a Cycas thoursaii.

Most of these can take colder temps than mine experienced, so I think you should be fine.

Hot and dry in the summer, cold with light frost in the winter. Halfway between the desert and ocean

Sapida,

Enc. F/G, cycadifolius and lanatus would be the most cold hardy, -8C is about 17-18F which is boardering on the lows for any encephalartos. We have had these species in the ground at that Temperature with no ill effects. The others from our experience would suffer leaf loss at that temperature.

Hope this helps.
