In late August and early September, this bushy cultivar of clematis is covered with hundreds of small white flowers edged in lavender or blue. Like most clematis, Mrs. Robert Brydon (Clematis x jouiniana 'Mrs. Robert Brydon') appreciates a location in the garden where its head can be in the sun and its roots in shade. Moderately moist, well drained soils are ideal. In the Chicago area it can be cut close to the ground in late fall, and it will regrow to a bush 6 feet in height and width by the end of the following summer.

This cultivar was discovered as a chance seedling in the garden of Mrs. Elizabeth Prentiss of Cleveland, Ohio in the 1930s and named in honor of the wife of her gardener. The parentage has recently been determined as Clematis tubulosa x Clematis virginiana.
