Rhododendron is State Flower of Washington

Updated on November 14, 2016

Rhododendron Macrophyllum

There are over 900 species of rhododendrons and azaleas come from the same genus.

This Rhododendron macrophyllum is also commonly called the Coast, Pacific or even the Big Leaf Rhododendron all of which are descriptively accurate since the leaves are large and this type of evergreen rhododendron is found along the Pacific Coast of the United States on up to Canada.

It is this particular rhododendron...the Rhododendron macrophyllum that is the State Flower of Washington and it typically blooms in the late Springtime of year.

Rhododendrons in Golden Gate Park

We were captivated by the beauty of rhododendrons in full bloom in Golden Gate Park one Spring. Golden Gate Park is located in San Francisco, California and is a wonderful place in which to spend hours or even days.

My hubby and I have spent some time in that glorious city park on two different vacations starting and ending in San Francisco prior to our return trip to Houston.

If San Francisco was on our radar for a future vacation, I would enjoy spending even more time in that distinctive and beautiful park.

Rhododendrons in Gardens

The Rhododendron garden was magnificent and those bushes literally towered over us! They grandly stood and displayed their gorgeous blossoms under the canopy of some neighboring pine trees. I am not sure what specific type of rhododendrons those happened to be.

They were probably labeled, but that was long before I ever thought of writing articles on the web.

My husband and I stood in awe of their display of beauty when we were out there on vacation one year.

We love our azalea bushes when they are in bloom and thought that these larger rhododendron shrubs looked to us like azaleas on steroids!

Like azaleas, most rhododendrons typically have shallow roots, like acidic soil and enjoy some dappled shade for ideal growing conditions.

You can see by the range map presented here to the right that their ideal growing climate is the far northwestern edges of our country including northern California, Oregon, parts of Washington and they even stray as far north as in bits of southern British Columbia, Canada.

If we had the right climate and growing conditions here in Houston, I would surely wish to add these beauties to our garden when first planning a landscape design.

At least we have their cousins...the azaleas to make us happy!

Keeping Rhododendrons in Shape

Here is more information about this flowering shrub if you are interested.

If you wish to know how to keep rhododendrons properly groomed, the video below explains it quite nicely.

Obviously if you grow them in your garden you would wish for them to be compact and tidy in appearance. If you have numerous plants it would take some effort but dedicated gardeners usually love tending their plants.

Rhododendrons in the Bayard Cutting Arboretum State Park

To see the beautiful Bayard Cutting Arboretum State Park located in Great River, New York on Long Island, you will certainly enjoy the video below. I would love to visit there someday when the rhododendrons are in bloom.

When traveling I always enjoy visiting gardens to see the various types of plants grown in that region of the country. Some specialize in certain types of plants and others are diverse in what is planted and grown there.

Sometimes we have made discoveries by seeing signs along the road. We got to see the Alfred B. Maclay State Gardens in Tallahassee, Florida because of that fact.

At other times when first planning a trip a certain garden was on the itinerary. Such was the case when visiting Bellingrath Gardens in Alabama.

      Hi Patricia,

      So glad that this was informative and that it taught you something about rhododendrons that you did not previously know. Appreciate your comment. :)

      Gorgeous....the videos and photos added so much to this, Peggy. It is indeed a lovely plant and I learned much that I did not know about them.

      Angels once again winging their way to you ps

      Hi FlourishAnyway,

      It is a shame that these beautiful shrubs are invasive in some areas. I did not realize that. Like all plants, if grown in the region from where they originated all is usually well.

      Hi Linda,

      So nice to be able to enjoy rhododendrons where you live. Southern British Columbia is so pretty from what I got to see many years ago.

      Beautiful flowers and hard to imagine them being an invasive and thus disdained species somewhere. I would love to have some purple ones in my yard! Stunning!

      Hi Jackie,

      Nice that they grow in so many places. They would be beautiful with a mountain as backdrop! Thanks for the share.

      Hi BlossomSB,

      I am not sure where they originated but they are listed as alpine native plants in most parts of the world. They must have been beautiful when you visited Scotland! Like you, we enjoy our azaleas.

      I love rhododendrons. I'm enjoying their appearance in southern British Columbia at the moment. Thank you for sharing the information and the lovely photos.

      They are also so beautiful in the eastern Virginia states. State flower of West Virginia I believe. I so love them with all that green backing and so lush along the mountains you can spot them miles away! Great pick for an article.

      Hi Blond Logic,

      That seems to happen often when plants that do well in one part of the world are exported to another place where they then become invasive. It is too bad when that occurs.

      I wonder where they originated? I've seen them in so many places in the world and especially remember a visit to the Island of Skye in Scotland when the rhododendrons were out; it was so beautiful. Our first home had a big garden with some lovely ones, but now I have a very small garden I have azaleas and they give a pretty show, too. Enjoyed the reminder.

      The first ones I saw (and noticed) were in Washington. I was very impressed by them. My husband, scoffed at them because they are a very invasive plant in parts of the UK where he is from.

      They are still a beautiful plant.

      Hello Thelma,

      Nice that you get to enjoy rhododendrons in the Blue Ridge mountains also. Enjoy their spring bloom. Our azaleas have pretty much finished blooming or are at the tail end of the season for now.

      Hi Bill,

      Nice to know from you just how hardy rhododendrons truly are. :) At least we have our azaleas!

      Hi Frank,

      So you live in the nutmeg state. Interesting! I would guess that you have some wonderful flowering plants where you live.

      I would be willing to bet I have never lived in a home in Washington where there wasn't one of these beautiful plants. They are a sure sign of spring and I would miss them living somewhere else....and for those thinking of getting one, they are practically impossible to kill. I'm proof of that. :)
