Hydrangea paniculata ‘Limelight’ is one of my favorite varieties. It grows 6-8’ tall and 5-6’ wide so it needs a generous space either planted alone or in groups. 5-6 hours of sunlight is required with a well drained soil but will tolerate a variety of soil types.

The flowers on this variety are large and billowy growing 5-10” long and 4-6” wide. They have a lime coloring that highlights the creamy white. They start blooming in August continuing to be showy well into the fall. As they age they turn an attractive dusty rose. Every season I cut these and dry them to bring inside for the winter months. If displayed in a cooler location they can last for years and can also be spray painted, looking especially spectacular in shades of burgundy and purple.

If you let them grow without pruning they will produce wide slightly arching branches eventually becoming woodier at the base. Annual pruning can be done to promote a thicker growth habit with foliage more dense to the ground. You may prune these back drastically only leaving thick wood trunks and they will re-grow the following season beautifully. Pruning can be done in either the late fall or early spring.
Find a place for this spectacular variety in your landscape. If you really don’t have the room for something this large, ‘Limelight’ now has a little brother ‘Little Lime’ with the same look but on a plant that stays under 5’.
