Spring time is Rhododendron time around the world. These prolific bloomers are native to Asia, North America, Australia, and Europe. They are members of the Genus Rhododendron  and the Family of Ericaceae (Heaths). The name is derived from ancient Greek (rhódon "rose" or“red") and déndron "tree”). There are some 800 to 1,000 species and 28,000 cultivars listed by the Royal Horticultural Society. Azaleas are a subgenera of Rhododendron.

Mostly known for the brilliant colors of their flowers, Rhodies as they are affectionately called, are also rated on the attractiveness of their foliage. In official ratings of the bushes, they receive a 1 to 5 rating on both the flower and the foliage, with a 5 being the highest. Thus like the example shown below, a 3/5 would indicate that the flower is averagish while the leaf is exceptional.

argyrophyllum ssp nankingese Chiese Silver 5-85

20013 Rhododendron argyrophyllum ssp. nankingense ‘Chinese Silver’ — (HY, hy, Argyrophyllum) 5’, 0oF, E-EM, 3/5. Perhaps one of the best foliage plants in the genus Rhododendron. The leaves are very shiny above, looking almost to be made of wax.
While their flower and leaves are very attractive, Rhodies can also be toxic, particularly to animals. Although humans probably don’t eat the flowers, they can be affected by eating honey made from the flower’s nectar.  If you have watched bees nosing around in the Rhodie blossoms all day as they do in my yard this will make sense.

Some species of rhododendron are poisonous to grazing animals because of a toxin called grayanotoxin in their pollen and nectar. People have been known to become ill from eating honey made by bees feeding on rhododendron and azalea flowers. Xenophon described the odd behaviour of Greek soldiers after having consumed honey in a village surrounded by Rhododendron ponticum during the march of the Ten Thousand in 401 BC. Pompey's soldiers reportedly suffered lethal casualties following the consumption of honey made from Rhododendron deliberately left behind by Pontic forces in 67 BC during the Third Mithridatic War. Later, it was recognized that honey resulting from these plants has a slightly hallucinogenic and laxative effect.[29] The suspect rhododendrons are Rhododendron ponticum and Rhododendron luteum (formerly Azalea pontica), both found in northern Asia Minor.
So, here is a display of Rhodies and Azaleas from my own neighborhood in Bellingham WA. All were photographed on my walks using either my Canon Rebel EOS or my iphone-5. They are presented in no particular order and I do not identify the species or cultivars as that would be an undertaking far beyond my ken and my patience.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
