Itea virginica: Virginia Sweetspire
Latin name: Itea virginica
Common name: Virginia Sweetspire
Flowers: Fragrant, white, showy flowers that create a drooping raceme 3 to 6 inches long. Bloom in late spring to early summer12
Fruit: Small copper capsules arranged in drooping racemes. Showy, and edible during late summer to early fall12,13
Height & Width: 3- 5 ft H by 3-5 ft W12.
Type: Deciduous perennial shrub 16
Habit: Dense, well rounded, and arching 4
Wetland indicator category**: FACW & OBL 17
Texture: Medium 16
Growth rate: Slow to medium 16
Light: Part shade 4
Moisture: Medium, occasionally wet soil. Good drainage, and tolerant of standing water13,16
Soil*:Prefers high organic matter, and pH ranges between 6 – 813
Zones: 5-9 13
Origin: Southern United States 16
Ecosystem benefits: Long fragrant flowers attract butterflies and other pollinators. Fruit and seeds are food for small birds. The ability to grow in wet ponds, and marshes provides shelter for smaller mammals12,13.
Features: This native species offers multi season allure, with little maintenance. This plant accepts wide ranges of soil quality, and is tolerant to standing water and pests13,16. During spring and early summer, small white flowers are produced on long drooping racemes, to create a showy overall appearance12.These fragrant flowers also attract insects and pollinators13 In the fall, the racemes turn to copper capsules with edible seeds, that provide food for birds12. The foliage on this plant also offers attraction because the oval, dark green leaves turn various shades of red and gold during the fall13.
Siting: For year-round visual appeal, this dense and well-rounded shrub should be planted in a well shaded, and occasionally wet soil location13. Common ornamental landscape uses are as border shrubs, and hedges in large groups, because just one plant can become scraggly12. For a natural aesthetic, the advantage of water tolerance can be implemented in ponds, riverbanks, and marsh settings to act as a wildlife food source, and source of attraction during multiple seasons10,12.
Care: Plant so crown/root flare is visible at soil surface14. At planting, water the root ball daily with two gallons of water per inch of trunk diameter for two weeks, every other day for two months and then weekly until established. Modify water recommendations to reflect site drainage and rainfall. Apply 3” of mulch over the planted area. Do not allow mulch to touch the crown/trunk14.
Pests: Plants are relatively pest resistant if cultural preferences are met12.
