Breck's Tennison Ridge Bearded Iris

Unlike standard irises that bloom only once in spring, the Tennison Ridge variety is bred to produce a second flush of flowers. You can expect vibrant color in late spring, followed by another display in late summer or early fall.

For the best results, plant your rhizomes about 12 to 24 inches apart. This spacing ensures adequate airflow, which is crucial for preventing rot and keeping the plants healthy as they mature.

Yes, this variety is considered deer-resistant. While no plant is entirely deer-proof if food sources are scarce, the texture and taste of bearded iris foliage are generally unappealing to deer.

While they are primarily garden border plants, you can grow them in large containers if you ensure excellent drainage. Given their 38-inch height, choose a sturdy pot that won't tip over in the wind.

The most important step is deadheading, or removing the spent flower stalks after the spring bloom. Providing consistent water and a light fertilizer application after the first bloom cycle also helps the plant store enough energy for its late-season performance.

The Tennison Ridge iris is hardy in zones 4 through 9. If you live in a colder climate within that range, ensure the rhizomes are planted before the ground freezes in the fall to give them time to establish roots.
