Gardeners' Notes:

i planted one of these in san leandro several years ago and it is now quite big and beautiful. the flower colour is just amazing. mine has the deepest magenta red flowers and as it ages, there are more and more of them. it really did not take it long to grow from about 6' to over 10', maybe 5 years? that's not too bad. it does seem to have a more columnar habit than most magnolias, though...maybe it's just my tree that has it. i've never seen another one anywhere to compare.

i now live in the sierra foothills and got one from the dreaded and sometimes hated wayside gardens recently. luckily, it is healthy with huge roots coming out of the pot. i've had some bad luck with them, going from great experiences beginning in the '90s to horrible experiences (when park seed took them over) and now back to pretty good experiences.

anyway, this tree is just so beautiful and if you can grow one, definitely try to find it. i rarely see them in catalogues or at nurseries, either in the SF bay area or up here in the sierras, but if you do find one, buy it at any cost. you will not be disappointed one bit.

This is my favorite magnolia. The first time I saw it 3 years ago, I stopped dead in the road just staring. It is that big, bold and beautiful. The darkest magnolia I have seen so far. A real delight!
