Jacaranda Trees
Q.

How hardy is a jacaranda tree?

Zone TN39 4DS, about 50 degrees of latitude. | [email protected] added on November 25, 2018 | Answered

A friend brought a jacaranda seed back from Queensland in Australia last year and grew it into a 3\\\" seedling which she gave me. Over the summer it grew into a fine tree nearly 4\\\' high. We live on the coast in the south of England where we don\\\'t usually get much below freezing - last year was cold and we got -2 degrees C. a few nights but I suppose it could get to -5 in a really bad year. I have just put the tree in our unheated greenhouse where it seems happy at present but is there anything safer I could do - put it in the unheated garage which is within the house or alternatively leave in the greenhouse and wrap with fleece? Also, is it better well watered or kept fairly dry? Also, have some red bougainvilleas in there - I presume they should be OK.
