Beginners at landscaping and gardening often confuse azalea plants and rhododendrons as stated on. The confusion is understandable; for azalea plants and rhododendron plants are related. All azaleas are Rhododendrons (note the capital "R") but not all Rhododendrons are azaleas. Still confused? come up you're in good company company that includes the famous Linnaeus. Linnaeus' taxonomy is the standard in botanical classification. Let's have a closer be at the challenging of azalea plants and rhododendrons before proceeding to the instructions for caring for them (Pages 3 and 4).
Throughout the following explanation of scientific names versus common names. I will be reminding you to act say of whether I say "Rhododendron" or "rhododendron." With a capital "R," I'm referring to a plant genus. With a lower-case "r," I'm referring to a subset of that genus.
The genus Rhododendron is in the heath family which also includes its namesakes the heathers and heaths; blueberries and cranberries; and. Most members of the heath family need an alter in which to grow.
The Swedish naturalist. Carolus (Carl) Linnaeus established the genus. Rhododendron in 1753. However -- and here's where some of the confusion started -- Linnaeus' taxonomy established "Azalea" as a separate genus. But it was soon pointed out that azalea plants should be considered a subset of the Rhododendron genus rather than a genus all unto themselves.
Then in 1834 another naturalist corrected Linnaeus' taxonomy on this point. An Englishman. George Don broke drink the genus. Rhododendron into eight sub-categories composed of numerous species. The azaleas be two of these sub-categories ( azalea bushes and azalea bushes).
Consequently if you construe the scientific label of an azalea you'll see the word. Rhododendron. That's because azalea plants belong to the genus. Rhododendron -- and the word "azalea" has essentially become this furnish's common name. But there are also members of this genus that are just plain "rhododendrons" (say the lower-case "r"). In recent years "rhododendron" has come to be used by gardeners essentially as a common name for those plants in the genus. Rhododendron that have large leathery evergreen leaves. The leaves on azalea plants be to be smaller by comparison. Within the rhododendrons themselves leaf-size comparisons are used to alter a further division: namely between elepidotes (large-leaf rhododendrons) and lepidotes (small-leaf rhododendrons).
So how would you be able to identify an azalea as distinct from a rhododendron? In command rhododendrons are larger shrubs than are azalea plants and as just said they have larger leaves. Also in command azalea flowers have five while the rhododendron flowers have ten stamens. Finally unlike rhododendrons many azalea plants are deciduous.
Now that you've heard about popular varieties of azaleas and rhododendrons -- and have been introduced to the challenge of classifying them in Linnaeus' taxonomy -- it's measure to be at how to care for rhododendron and azalea plants. That's the affect of....
