Large lavender blooms in spring, evergreen foliage and an ability to thrive in fairly shady conditions make the Boursault rhododendron an excellent addition to certain landscapes. Flowers first appear as deep purple buds before opening to a lavender with occasional reddish-brown markings. These funnel-shaped blooms appear in clusters at the end of branches and really put on a show. When planted in a well-chosen and prepared site, the Boursault rhododendron is a dependable performer with low maintenance requirements.
Native to the eastern United States and hardy in USDA zones 4 to 8, this plant forms dense thickets that offer a nectar source for butterflies and shelter for birds and wildlife. The blooms and rounded shape alone can make it an interesting accent plant. This cultivar of Rhododendron catawbiense also has a dense, spreading structure that is also perfect for an informal border. It has a moderate growth rate and can tolerate urban pollution.
Boursault Rhododendron Care
Choosing and preparing the ideal planting site for this shrub is important. It prefers partial shade, with some protection from hot afternoon sun and strong winter winds. Its roots require well-drained soil, but do not like to dry out or overheat, so regular watering during dry weather and mulching around the shrub helps to retain moisture and keep soil temperatures cool. Additionally, rhododendrons like this one need acidic, organically-rich soil to thrive, so work compost or another organic material into the site prior to planting and occasionally apply a fertilizer for acid-loving plants.
Rhododendrons bloom in the spring on growth from the previous summer, so any routine pruning should happen shortly after blooming has finished. Cut back stems about one-third in order to give the plant the desired shape. Planting a Boursault rhododendron in an improper or poorly-drained site can lead to problems with diseases and poor plant health.
Boursault Rhododendron Spacing
Boursault rhododendrons work well as an accent plant or as an informal hedge or border. It has a spreading branch structure and grows to be 6 to 10 feet tall and wide; plant specimens or hedges with this spacing in mind. It has shallow roots that do not like to be disturbed, so avoid planting annuals or cultivating around the shrub.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
