I am only commenting in passing, and do not have any particular comments for the original poster.
I do want to vigorously object to the position that Rhododendron
sp. are the only flowering evergreen plants for the north (all the native Kalmia
are currently scowling). Additionally, many Holly species (Ilex
sp.), Japanese Pieris (Pieris japonica
), and a few Magnolia species like Sweetbay (Magnolia virginiana var. australis
) will be evergreen in many coastal northerly places like Brooklyn.
As a proud former officer in the Holly Society of America, I take particular affront to the idea that Ilex opaca
is "...a particularly attractive (though non-flowering) evergreen..."
. Did someone glue those incredibly attractive red fruit onto those branches?
Though often not always showy, American Holly indeed DOES flower - and is highly fragrant and a huge favorite of bees, at that. Say hello to a few examples...
"Any questions?" (that's what the last image is saying)
