Amelanchier arborea | Serviceberry

IMG_6503.JPGAmelanchier arborea | Serviceberry

CHARACTER
Native to MD, and Northeast US. Beautiful small tree or very large shrub. Multistemmed with amazing red fall color. But the lacey white racemes of flowers which cover the plants are the real joy of this plant. Can be id’d by its yellow-green buds and pendulous friuts. Serviceberry has red edible fruit, berry like pomes, that tastes like the sweetest blueberries and are enjoyed by birds. Great to soften building corners or naturalize yards where there is space. Nice with dark backdrops to emphasize the shape. They hardly need any attention to thrive.
CARE
Transplant B&B. Keep in shape by removing unwanted succors.
NOTES
Also known as Juneberry and Shadblow (weird name) refferring to the bloom time when shad run.

Rhododendron ‘P.J.M.’| PJM Rhodies
CHARACTER
Smaller than many standard Rhododendrons, a blend between regular Rhodies and Azaleas. One of the first Rhodendrons to bloom in the spring around mid-March, with a heavy nice dark pink uniform blooms, almost plum colored. PJMs don’t come in any other bloom color. At least it’s not fuscia. The leaves are smaller and a very attractive dark green, maroon bronze in winter, which I love.
CARE
Does well with an elevated bed of top soil, since it has very shallow roots. Once established, it doesn’t like to be disturbed. Treat like any other rhododendron – acid lover.

NOTES
PJMs originated in MA and so very hardy. Also works in bleak Midwestern winter as it turns spring. East Coast and Upper Northwest are THE places to grow Rhodies, in the US.
RELATED VARIETIES | CULTIVARS | EXTRA INFO
over 900 species and countless cultivars, imporvements have come with hybridization, especially for cold hardiness. The hardiest apparently come mainly in purples and magentas – hmmm? There are many even with other colors listed in Dirr, but I how available they are. I will add them as I see them.
