April Showers

Rhododendron 'Blue Baron' Greetings from a wet, wet garden. In between rains, I've managed to get a few photos... (And sorry for the erratic quality of these. I have a new phone and still learning how to use it. Some of these are from the phone and others from my camera). Acer japonicum 'Aconitifolium' ('Dancing Peacock') Flowering Currant ( Ribes sanguineum ) 'King Edward VII' Clematis 'Stolwijk Gold' is beautiful for the first time after languishing in the garden for five years. Turns out, it is all my fault. This is a clematis that should not be cut to the ground in early spring. You live and learn, and I know that I will never understand the rules of pruning clematis.  Clematis 'Stolwijk Gold'  Aucuba japonica 'Rozannie' - the aucuba that doesn't really look like the others.  But what a fine shrub this is, especially for shady situations. This was planted in 2019 and didn't grow much for the first few years but n...

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.
