High Country Gardens Jawbone Flats Bearded Iris

With a mature spread of 12 inches, you should space these irises about 12 to 18 inches apart. This allows for proper airflow, which is essential for keeping the rhizomes healthy and preventing rot.

Tall bearded irises typically need one full growing season to establish their root systems. While you may see some blooms the first spring after planting, they will reach their full, vigorous flowering potential in their second year.

Iris germanica requires soil that does not hold standing water, as damp conditions can cause the rhizomes to decay. If you have heavy clay soil, amend it with organic matter or plant on a slight mound or raised bed to ensure excess moisture drains away quickly.

No, the Jawbone Flats Tall Bearded Iris is not bred for fragrance. Its primary appeal is its striking amethyst and purple coloration and its impressive 44-inch height.

At 44 inches tall, these irises are quite sturdy, but they can be susceptible to strong winds or heavy rain. If your garden is in a particularly exposed or windy location, you may want to provide light staking to keep the stems upright.

Once the flowers have finished, leave the foliage intact throughout the summer. The leaves are essential for photosynthesizing and storing energy in the rhizome for next year's growth; you can trim them back in late autumn after the first frost.
