'Black Joker' flowers have so many different and unusual colours on display. There is purple that is almost black and trimmed in gold, mauve and yellow side by side, and a lovely blue lavender!
They are hardy and vigorous growers that were meant to be in our catalogue and in our gardens! One of the most easily grown Iris, Iris siberica originate from Northern Asia. These are very cold-hardy plants. Generally the species produces light blue flowers but cultivars will have flowers of other colors. The plants will tolerate wet soil but will also grow well under normal garden culture. Iris siberica will do well under all types of weather conditions. Be sure to cut the plants back to a height of 6" - 15 cm in the fall. They make good cut flowers.
