Because of the unusual freezing temperature in early Spring 2007, some of the azalea flowers in Missouri was partially damaged. However, I'd captured some pretty good pictures of azalea before freezing at the Garden.
Azaleas are flowering shrubs making up part of the genus Rhododendron. Originally azaleas were classed as a different genus of plant, but now they are recognised as two of the eight sub-genera of rhododendrons.
Rhododendrom is bloomed a little later than azalea and was not affected by the frost in April. Rhododendron is a very widely distributed genus, occurring throughout most of the Northern Hemisphere except for dry areas, and extending into the Southern Hemisphere in southeastern Asia and northern Australia.
