Experience the National Arboretum's treasured Azalea Collections
Spring is upon us once again, and the National Arboretum is rich with bloom – from the spring ephemerals to the daffodils,
magnolias and cherries planted throughout the grounds. This column which begins today and will change each week for the
next eight weeks will focus specifically on our Azalea Collections and the status of bloom.
The best time to schedule your visit is on a weekday, but if weekends are your only option, a stroll through the garden before noon or during a light rain offers an enviable second choice. A drive around Azalea Road can be exhilarating because of the views of the collection, but if you can afford the time to take a walk, it is worthwhile. Pick up a brochure at one of the three major entrances to the collections or at the Visitor Information center and begin your journey into the world of azaleas.
Learn more about the Azalea Collection here. For more in-depth information on growing and caring for rhododendrons or azaleas, check out the FAQ pages here. Visit our Azalea Photo Gallery where you will find over 200 images of the flowers of more than 100 of the Glenn Dale azalea varieties.
In the meantime, check back here each week as we update you on the current conditions in this year's Azalea Blossom Watch.
Greetings to our friends and guests!
Peak Bloom Prediction
Bald Eagle Nest On Glenn Dale Hillside
This week, the Azalea Collection has many buds showing a hint of color forecasting the brilliant display to come in the next few weeks. Last week, temperatures soared to the low 80’s. This is quite warm for the early flowering plants like daffodils and many of the cherries and magnolias, speeding up their blooming period. The warm temperatures will also speed up the opening of early azaleas.
Early species such as Rhododendron mucronulatum, and the Weston hybrids are in bloom today. They consistently flower at the same time that forsythia in is full bloom. The evergreen azaleas that are showing color this week include many of the Glenn Dales which are planted in and around the Morrison Azalea Garden, and the reliable but beautiful Kurume azaleas found along the Henry Mitchell Cultivar Walk. A few of our native deciduous species such as Rhododendron austrinum (the Florida Flame Azalea) will be in bloom by the end of the week.
For information on when and how to prune azaleas, when the best time to plant and transplant azaleas and much more, check out our FAQ link at: http://www.usna.usda.gov/Gardens/faqs/azaleafaq1.html.
See you in the garden.
