Rhododendron x P.J.M.

Rhododendron x P.J.M.

Easter is the time of flowering for so many plant groups and for us the hybrid Rhododendron P.J.M. leads the way.  It is very hardy with small dark green leaves that never look bad.  They don’t suffer from the Lace Bug that hits the Azaleas and over 30 years our plant has never had a bad year.  This is a hybrid of the Korean Rhododendron (R. Mucronulatum) with our native Carolina Rhododendron (R. carolinianum).  It’s interesting to read the story of the discovery of this series of hybrids at Weston Nurseries in 1945 as relayed by Peter J. Mezitt’s son Edmund.  In just about every way the P.J.M. exceeds its parents.  

P.J.M. hybrid becomes a sizable shrub after 30 years.

    That’s a great P.J.M. specimen; it’s interesting that it doesn’t get hit by the lacebug as much. Our R. mucronulatum is just starting to open. However, isn’t P.J.M. a cross of R. carolinianum and R. dauricum var. sempervirens?

      It looks like P.J.M.’s are more a group of plants than an individual. The original P.J.M. was indeed from the R. carolinianum and R. dauricum v. sempervirens but R. mucronulatum was introduced into the gene pool in 1958. There is quite list of P.J.M. hybrids and it would be hard to know which one we have. A very detailed history is given Sally Perkins in a note to the American Rhododendron Society Massachusetts Chapter.

    I am so glad you posted this, because I saw this azalea growing in the display garden of a local nursery and it wasn’t labelled. It’s the most purple Rhod. I’ve ever seen.
