Guelder Rose Viburnums are deciduous shrubs that are easy to maintain with landscaping needs as they do not grow very tall, only about 13 to 25 feet high with only around 8 to 12 feet of spread. Viburnums do face a host of various pests and threats such as aphids and thrips which can cause curling and purple spots, respectively, to appear on the shrubbery. Viburnums bloom in late summer, allowing for ease of maintenance during much of the summer.
