Japanese Maples Fall Color

'Skeeter's Broom' is the most colorful maple in our garden. I have just returned from a 2-week trip to Japan. This was my first ever trip outside the United States. It was an amazing experience and one I will never forget. Japan was wonderful - they really have their act together and I think the U.S. could learn a few things from them. There was one disappointment on the trip - the fall color had barely begun there and was really just beginning as we left. That is okay because the gardens were still spectacular, and I got a nice shot of fall color when I got back. 'Ryusen' I missed a few things - our ginkgo had just turned a glorious color the day before I left, and the leaves were gone by the time I got back.  'Sango-Kaku' I came home to many leaves on the ground but still a lot on the trees. 'Osakazuki', a beautiful red maple always changed color very late and therefore doesn't usually last long. When I left there was no color but a few remaini

Rhododendron 'PJM'



For me, Rhododendron 'PJM' is one of the main plants that signal the beginning of Spring. Nevermind that it is rather pedestrian, dotted everywhere around town and often residing on properties where it is obvious that gardeners do not live within. The reason for this is that, when it comes to rhododendrons, it is very cold hardy and one of the easiest to grow.

The story behind it is an interesting one. It was developed by Edmund Mezitt, the son of Peter J. Mezzit, an emigrant who fled the Russian czar and came to America in 1911. He and his wife Olga founded Weston Nurseries in 1923 in Connecticut. Their son, Edmund, had a passion for rhododendrons but was discouraged by the selection of offerings in the New England region. In 1939, he crossed Rhododendron carolinianum, a plant native to the Carolinas and Tennessee with Rhododendron dauricum var. sempervirens, an extremely cold-hardy plant gifted to his father by Russian missionaries. The result, Rhododendron 'PJM', named after his father's initials, took the country by storm and made their nursery famous.

I see 'PJM' growing in a variety of conditions - full sun, part sun, shade - it all seems to work but I would recommend a partly shady spot with preferably morning sun. It grows about 3 - 5 ft. in height and is upright. Today there are other varieties including 'PJM Elite' which has slightly brighter color and suppose to be more compact.

    That's a good story. We often don't know how plants ended up for sale in our local nurseries or on line. Millions growing around the world that were once a single seedling.

    That intense color sure wakes up the eyes in a grey spring!

    I planted PJM Rhododendrum a few years ago. Very little direct sun made it grow leggy branches, it lost the lovely bronze-colored leafs it had when I punched it, and it produced 5 blooms this year. I'm rather discouraged.

      Actually mine is not very dense. I wonder if pruning would help?

    So commanding with the bright color. I know rhododendrons are common, but I miss them (grew up in Portland, OR now in CA).

    What a great story! Thank you for that! I know they are common, but damn - there is a reason for that. I love that dark foliage contrasted with that nearly fluorescent purple. If I had room, I would totally plant one.
