Plant of the Week
Itea, Virginia Sweetspire
Latin: Itea virginiana
Choosing plants for your landscape can be somewhat bewildering given the thousands
of choices in nurseries.
To help make the choices easier, the Department of Horticulture has teamed up with the Arkansas Nurseryman’s Association and the Arkansas Greenhouse Growers to identify plants that will do well across Arkansas. The program, known as Arkansas Select, is in its third year and has been warmly received by state gardeners.
For 2000, six plants were designated as Arkansas Select winners. They include two woody shrubs, two perennials and two annuals. Over the next six weeks, I will attempt to describe these plants in some detail and point out their garden merits.
Landscape styles are changing and Itea fits the new style perfectly. Gone are the days where stiff formality of tightly pruned balls are the norm. Now the loose and fluffy look is in.
Itea, traditionally considered a member of the Saxifrage family but now being reclassified weekly as the new taxonomic order takes shape, is a native to the southeastern states from the Pine Barrens of New Jersey to east Texas.
It has been reported in about half of our Arkansas counties, all the southern or eastern part of the state. While in the wild it typically is found associated with moist and even swampy sites, in the landscape it conforms nicely to the moisture regime of the average garden.
Itea grows 3- to 4-feet tall and spreads horizontally by means of underground stems about twice its height. It tends to produce ascending branches that often slightly arched near the tip. Leaves are typically 3 inches long and 1-inch wide and a lustrous green in the summer. In the fall the leaves turn shades or red, maroon and orange and persist well past Christmas. The flowers are slightly fragrant and appear in April as white, pendant bottle-brushes to six inches long.
Two cultivars have been given the nod by the Arkansas Select committee. "Henry’s Garnet" was the first named selection of Itea, being named only in the 1980s from a plant growing on the campus of Swarthmore College from seed that had been collected in Georgia. The seeds were collected by Josephine Henry and garnet is the school color, hence the name. "Saturnalia" is the second selection highlighted, because of its Arkansas connection. Larry Lowman, a nurseryman from Wynne, introduced this plant in 1995 from material he collected while canoeing in Tennessee. It is said to be slightly more compact than Henry’s Garnet and have yellow orange fall color instead of red.
If you have a control fixation and constantly feel the urge to use hedge shears, Itea is not for you. But, if you can appreciate gracefully arching branches and an open, naturalistic look, this shrub is a good choice for massing in the border. It grows in full sun to medium shade in typical garden soils. Though native to wet areas, it has good drought tolerance.
In my garden, the planting in a well watered location is 3 feet tall and spreading rapidly. The planting under a thirsty elm tree is only about half as tall, but holding its own against an aggressive competitor. No serious disease or insect problems have been noted.
