Azalea Bloom Time Zone 5
Rosy Lights is an azalea that offers extra cold hardiness.
Azalea bloom time zone 5. Spring summer and fall. It is a very hardy very good plant but blooms early and the flowers get frozen back some years. Prune in spring after flowering.
While many varieties of azaleas bloom only one time a year the rebloomers listed below are azaleas that will bloom two to three times a year during the warm season. Like rhododendrons azaleas thrive in acidic soil and cannot tolerate alkaline soil. Rhododendron PJM is in that category for us.
Post date July 27 2021. It thrives in zones 6 through 10 and enjoys part to full sun. While most Azaleas are cold hardy to USDA Zone 7 or 8 meaning they will tolerate low winter temperatures to 0 to 5 degrees Fahrenheit we now offer a few varieties that are cold hardy as far north as USDA Zone 5 which has low winter temperatures to -20 degrees Fahrenheit.
These plants dont grow well if subjected to prolonged temperatures over 90 degrees Fahrenheit and may die out if winter temps fall below about minus-5 degrees. Keep roots cool with a layer of mulch. Now you can have repeat blooming azaleas flowering all season long.
Zone 5 azaleas grow best in an area where they can receive a lot of sunlight but are slightly shaded by tall trees in the afternoon heat. These summer bloomers are an easy sell for their fragrant flowers attraction for pollinators and great fall color. Stewartstonian is well suited for the climate variations found in USDA zones 5 to 8.
Nova Zembla is an evergreen rhododendron that grows 5 to 10 feet tall and bears bright red flowers in late mid-season. Dont miss out on adding some late color to your spring borders in the form of the deciduous Azaleas. There are those that will make a show through summer but that will.
