Over the past few decades, gardeners have become more environmentally conscious, employing eco-friendly principles in the landscape, such as using less pesticides, composting more and even installing rain gardens.
Gardeners also have changed what they plant, incorporating more pollinator-friendly plants, as well as native species into the landscape.
Virginia willow, also called Virginia sweetspire and known botanically as Itea virginica, is one of our more popular native shrubs in Louisiana. Interest in this shrub has increased in the past 10 to 20 years with a variety Henry’s Garnet Virginia willow, which is the newest addition to the LSU AgCenter Louisiana Super Plants program for spring 2017.
The Louisiana Super Plants program is an educational and marketing campaign of the LSU AgCenter that highlights tough and beautiful plants that perform well in Louisiana landscapes. Louisiana Super Plants have a proven track record and are university tested and industry approved. Homeowners and horticulture professionals alike can benefit from using Louisiana Super Plants to ensure a successful landscape.
The intoxicating smell of the Henry’s Garnet Virginia willow flowers is a major feature of this native shrub. These white flowers are borne on 4- to-5-inch clusters. This shrub will bloom for a four- to six-week period in spring, starting roughly the same time azaleas finish up. The flowers stand out remarkably next to the lush, dark green foliage.
Henry’s Garnet Virginia willow is a lower-growing shrub, topping out at about 5 feet and spreading out about the same. Sometimes, the plants can be slightly wider than tall due to its clump-forming growth. Prune any undesirable growth in spring after flowering is completed. Avoid pruning in winter or early spring as this will inhibit flower production the following spring.
Foliage of Henry’s Garnet Virginia willow is especially handsome in fall. The leaves turn a brilliant deep red-purple and persist late into the fall. Plants are deciduous in some areas but actually are semi-evergreen in this area, retaining some foliage all year.
This plant tolerates Louisiana's wet and heavy soils but also performs well in drier sites. It is frequently found in the wild in locations that have moist soil. Henry’s Garnet is now being used in rain gardens in commercial landscapes around the state.
Virginia willow is also adapted to a wide range of soil pH and can adapt to almost any soil type or drainage situation in a landscape. Even though they prefer a slightly moist soil, they are very drought-tolerant. Morning sun with afternoon shade is a nice planting location.
For best results, fertilize Virginia willow once annually with a three- to four-month slow-release fertilizer. Apply fertilizer in late winter just prior to new growth or in mid- to late spring after flowering.
Henry’s Garnet Virginia willow would look great paired with other Louisiana Super Plants, such as evergreen sweetbay magnolia, Conversation Piece azalea and Mrs. Schiller’s delight viburnum. Nice flowers, nice foliage, native and site adaptability make Henry’s Garnet Virginia willow a perfect addition to your landscape.
