Twenty-two acres of year-round botanical splendor make up the Rhododendron Species Botanical Garden. It is home to one of the largest collections of species rhododendrons and azaleas in the world. The RSBG continues to support the conservation, preservation, distribution and display of the rhododendron species. Some rhododendrons in the collection no longer exist in their wild habitat.Wild rhododendrons have a great diversity of size and shape with flowers that range in color from white to soft pink, clear yellow, brilliant red and into deep purple. Rhododendrons can range in size from ground hugging alpines to 100 foot trees. The RSBG collection consists of species from North America, Europe, Asia and Africa.A visit to the garden will increase your knowledge of these extraordinary plants that are growing among a forest of conifers and deciduous trees.

Exploring the Rutherford Conservatory will provide you with a showcase of tropical rhododendrons as well as many other tropical plants. Hundreds of these beautiful tropical plants are set along a stream with a waterfall and towering boulders. There are over 10,000 rhododendrons in this woodland garden.

A newly-renovated gazebo in the center of the Garden gives an expansive overview of the landscape. Travel the garden paths to the Victorian Fern Stumpery, Alpine and Pond Gardens and the breathtaking Blue Poppy Meadow (Meconopsis.

After enjoying this show come and browse the Garden Gift Shop and Nursery. Many of the plants found growing in the Garden are for sale in the Nursery or through our on-line catalog.

Glad we stumbled upon this place. The rhododendron seemed to be in a natural setting and growing wild. I must have seen over 30 variety. They also as an azalea garden. Very nice.

This garden is amazing if you love Roadies (our state flower). Not only have they gathered every known species. But they have cross pollinated many exotic species to create unique one of a kind mixes.

If you enjoy walking through Pacific Northwest forests and meadows, if you'd like to see how this serene (but for the sounds, at times, of traffic on Highway 18 and I-5) 20-acre facility has integrated over 700 species of rhododendrons from North America, Eurasia and Australia with our native plants, if you're a serious gardener or if you're all of...

It is a large garden with lots of paths to walk around. We have visited it a number of times and seen and bought some rare plants which look good in our garden. For gardeners it's well worth a visit.

A greene oase which is worth visiting ud you are looking for some jungle feeling :). Unfortunately the interstate right next to it is quiet noisy to be able to fully relax

Glad you enjoyed your jungle-like visit! When a person imagines they are hearing the roar of the ocean instead of the road, it disappears into the background. ;o) Thanks for your comments. More

Feb. & March are best time to see rhodies in bloom, however it seems that no matter what time of year you visit there is something in bloom. A must see if visiting the... More

I took my French exchange student here and we loved exploring the trails that took us to little collections of rhodies. You can "hike" to several spots and each is very photogenic. It is also pretty cheap and beautiful. Would recommend pairing with the bonsai museum next door.

The Rhododendron Species Botanical Garden is the best collection of rhododendron species in the world if you are into rhododendrons. Even if you are not knowledgeable about rhododendrons it is still an excellent garden to visit any time of the year, but spring is really special. I have been there many times and there is always something new to see.
