Early Rhododendrons Blooming at the Washington Park Arboretum
1) Rhododendron arboreum hybrid
- The earliest, longest blooming rhododendron in the Arboretum (November-March!)
- Due to its floriferous nature, even in the coldest winters when it sustains bud blast from a deep freeze, it usually never fails to flower afterwards.
- Located in Witt Winter Garden, this rhododendron is worthy of naming and becoming a WPA plant selection.
2) Rhododendron ‘Cilpinense’
- Hybrid between parents of two Chinese spp., Rh. ciliatum and Rh. moupinense
- Compact, low-growing rhododendron that blooms in late February into March
- Nice grouping located in Winter Garden, bed F
3) Rhododendron mucronulatum ‘Cornell Pink’
- My personal favorite harbinger of spring rhododendron
- Species is native to Korea, a.k.a. Korean rhododendron
- Can’t miss ‘em beginning to flower at north end of Azalea Way, x from GVC
4) Rhododendron ririei
- Large rhododendron, best in partial-shade for vivid magenta-purple color to show
- Native to Mt. Omei, W. Szechwan and flowers late February – early March.
- This specimen is located in Loderi Valley, southwest bed with hemlock cvs
5) Rhododendron strigillosum
- Rare, rich red flowering rhododendron in late February – early March
- Stiff, bristly leaf-stalks and narrowly-oblong leaves provide added texture and show
