Hydrangea Paniculata Is Dependable And Very Winter-Hardy
Director of Horticulture, Les Lutz
As we move through the latter parts of July and into August, this species will start its show. Driving through various parts of the Cape, I see Hydrangea paniculata used to great effect and for good reason. This species is dependable. Always dependable. It can survive our winters with no worries and is considered one of the most winter-hardy of the Hydrangeas. It can also survive gardeners pruning with no problem as it flowers on current years’ growth. Even if you prune the plants hard in the spring, which is when many folks, tired of being inside all winter and itching to prune, take their pruning impulses to their hydrangeas, often to ill effect.
Best grown in organically rich, medium moisture, well-drained soils in full sun to part shade. This species is usually grown as a single-stemmed shrub but can easily be trained as a small single trunk tree or often as a ‘standard’, but is best grown as a large shrub.
‘Limelight‘ is probably this species most famous cultivar and has been in the trade for years. According to multiple sources this cv can grow to 6-8’ but realistically I’d put the height, without pruning, at more like 25’. But there are many, many new cultivars available. A quick search online and I’ve found 22 cultivars and I’m sure there are more. Of the major plant producers, Proven Winners has eight cultivar’s, Bailey Nursery has seven and Monrovia lists seven and each are introducing more each year. READ MORE
