Dynamite Bearded Iris (Iris germanica Dynamite) sizzles with its large blooms of almost “fire-engine red” flowers. This spectacular Iris is one of the very best reds and adds unusual, big color to the late-spring garden. Large flowers, 4 to a stem, steal the show with eye-popping color. Tall and stately at 30-36”, ‘Dynamite’ is an excellent choice for focal points, perennial borders, garden walls and entrances. Not picky, easy-to-grow, and pollinator friendly, they make great cut flowers too.
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
Dynamite Bearded Iris (Iris germanica Dynamite) blooms in rich, deep reds with golden-yellow beards. If “spectacular” is on your shopping list, look no further! This tall bearded Iris adds vertical interest with unusual color. Combine with other Iris, Allium, poppies, ornamental grasses, or as a focal point at an entrance, or in a perennial bed. The flowers are large, and the color is deep – ‘Dynamite’ loves attention! Easy care, cut or snap off spent blooms, then cut the stems back after flowering is finished. The clean lines of the foliage will continue to add interest all season long. Cut the foliage back after the first frost, and top dress with bone meal. In the spring feed an organic bulb food and get ready for more spectacular flowers.
