We were thrilled to have a great flower show this year on the most winter hardy honey myrtle we grow, Melaleuca ‘Wetland’s Challenged Mutant’. This introduction from Desert Northwest, is either a selection of Melaleuca paludicola, or a hybrid with that species. Most of the other “hardy” melaleucas (formerly, Callistemon) died to the ground this year, but this clone of the alpine honey-myrtle from Southeastern Australia didn’t even suffer burned foliage, and flowers buds were obviously fine. Our 11 year old plant is 7′ tall, and has endured two single digit winter temps; 7F, and 9F. Hardiness Zone 7b-10b.
