Early Season Nectar Source

Snow white flowers with butter-yellow crests nestle just above arching blades of green foliage. Native to eastern and central North America; it spreads nicely to form dense colonies. Ideal for a spring woodland garden or shady nook. Iris Tennessee White comes from Don Shadow Nursery in Winchester, TN. Its late spring show starts earlier and lasts longer than other Dwarf Crested Iris selections. Iris Tennessee White will tolerate some sun if soil is consistently moist, but still must be well-drained. Dwarf Crested Iris bloom early to provide a welcome nectar source for the first butterflies and bees on the garden scene.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
