Iris virginica
Commonly known as Virginia Iris, Southern Blue Flag, Great Blue Flag, and Blue Flag Iris.
Native primarily to wetlands, marshes, lake sides, stream banks, and other moist, open areas in the eastern half of the United States and southern Canada. It typically grows to 2' tall (less frequently to 3') and features non-fragrant violet-blue flowers with falls that are crested with yellow and white. Flower color can vary considerably from very light blue to purple. Bright medium green, sword-shaped leaves often lie on the ground or in the water. Blooms in late spring.
Best grown in wet, boggy, acidic, sandy soils in full sun. Also does surprisingly well in average garden soils that are kept consistently moist, however best performance in the border will generally occur with sandy-humusy, water-retentive soils that are never allowed to dry out. The species is often found in the wild growing in standing water, and this cultivar may be grown in shallow water (up to 6 "). Tolerates light shade, particularly in the southern part of its growing range. Clumps will slowly spread by creeping rhizomes to form colonies in optimum growing conditions. Divide plants when overcrowding occurs.

Spring Shipping:
Orders are shipped within 7-10 business days. We will email you if there are expected delays.
When you order plants from our nursery, you can expect them to arrive in the best possible condition. Our team carefully packs each order using sturdy, biodegradable packaging materials.
Your plants' appearance may vary depending on the season and their current growth stage. We may cut back the leafy growth of some plants to prepare them for shipment and transplanting.
5 Gallon and Up: Any plant purchased to ship over 5 Gallons will be shipped bare root. This means we will remove the plant from its original pot, remove the soil surrounding the roots, and wrap the roots with a biodegradable plastic bag. This reduces weight and the likelihood of damage during shipping.
Once your plants arrive, it is essential to plant them as soon as possible. This will help them rebound and thrive. If you cannot plant immediately, water regularly and keep the roots off heat-conducting surfaces.
Newly transplanted plants often require more water until their roots are well established. Plan to water them 1-3 times weekly for the first few months.
