Mick great info, so I will be attempting to grow Leptospermum Scoparium, as I have obtained the seed. I have the ability here to protect young trees if the need arises, but if the manuka can tolerate snow, it surely will grow at my place unhindered. I will be sowing seed after Christmas, when I actually come out of the winter with the desire for the seed propogation that moves over me like a blanket. I am not near the beach so the l. laevigatum would not survive. Thanks. Great day, Cindi.
