Oh boy! Do we have a brilliant idea for you! No, seriously, adding a Brilliant Idea Tall Bearded Iris (Iris germanica 'Brilliant Idea') to your garden is a wise decision. Planting of few of these blue, white, and yellow gals is a no-brainer. The Brilliant Idea Iris looks spectacular from every angle!

This amazing cultivar doesn't just produce a few striking flowers, it produces up to sixteen blooms in one season! This amazing Iris has two branches that will sprout with six to eight flowers on each from mid-spring almost into summer.

These Bearded Iris flowers are true show-stoppers. They feature true-blue bands along the margins of each blue and white fall. These margins of blue show off these blooms' ruffled edges as they feather into the white. They also have honey-yellow 'beards' and white standards that really make the blues pop!

The Brilliant Idea Iris stands tall on strong and stunning green stems. It also features an attractive mound of thick and hardy green leaves that are both rabbit and Deer-resistant.

Planting and Application:

When the Brilliant Idea Tall Bearded Iris blooms, your neighbors might be inspired to share in your brilliant idea and order a few of their own. These large blooms are impossible to ignore but their color makes them easy to admire from a distance. They even attract the attention of bees and butterflies. They pair well with other Iris varieties, Peonies, and Tulips for a long-lasting bloom season.

Impress your neighbors with a show of Brilliant Idea Tall Bearded Irises as foundation plants. They also look amazing and will encourage your neighbors to admire them when planted around your mailbox or along your driveway.

#ProPlantTips For Care

Encourage the Brilliant Idea Tall Bearded Iris to shine with large blooms by planting it in a full sun location in rich, quick-draining soil. Provide regular moisture, but once established, they only need supplemental moisture during prolonged heat and drought. Add a layer of mulch around the base to conserve moisture and protect the roots.

Deadhead the flowers as they fade and trim back the foliage in the autumn. Every 3-5 years, divide the clumps and rearrange the rhizomes to keep them in tight formation and to prevent them from being buried too deeply, preferring to be planted more shallowly in the ground.

Keep Iris rhizomes exposed in cooler climates or buried just under the surface in hotter climates. Water it well while it's rooting and less after it's established. For the winter, loosely cover your Iris in a layer of clean leaves, straw or compost, pulling it away in the spring.

  • Full Sun Perennials
  • Loves High to Average Moisture

  • Deadhead After Flowers Fade & Trim Stems in Late Autumn

Information About Bare Root Iris

Bare root Iris are shipped as nice fresh-cut divisions with two to three fans of green tops. Keep in mind each Iris variety can have slightly different-sized roots.

When planting, make sure 1/3rd of the rhizome is exposed to sunlight with the roots buried underneath. Note, that it's best to cover the rhizome with a thin layer of mulch or leaves to protect it during the coldest months but make sure to uncover them in the spring.
