Bearded Iris Califlora Tennison Ridge

A reblooming iris typically flowers once in the spring and then produces a second flush of blooms later in the summer or fall. For the Tennison Ridge variety, this reblooming behavior is reliable in USDA zones 5 through 10.

Plant the rhizomes shallowly, with the top of the rhizome sitting just beneath the soil line. If you bury them too deeply, the plant may struggle to bloom or could be prone to rot.

Yes, Tennison Ridge is bred to be drought-tolerant and hardy. Because these plants are cultivated in harsh conditions on a California farm, they are well-adapted to withstand challenging environments once established.

While no plant is completely immune to hungry wildlife, Bearded Irises are generally unpalatable to deer and rabbits. Their texture and taste usually deter these animals from browsing on them in the garden.

These irises thrive in full sun to light shade. For the best bloom production, aim for a spot that receives at least six hours of direct sunlight daily.

Space your rhizomes 8 to 12 inches apart. This allows for adequate airflow, which helps keep the foliage healthy and prevents overcrowding as the plants multiply over time.
