Indigo Shrubs belong to a broad family and are distributed throughout temperate to subtropical regions. They have elegant feathered leaves and terminal and axillary racemes of usually pale pink to pale lilac flowers. Winterhardy species from Eastern Asia and North America are mostly deciduous and they are easily grown in any rich soil in a sunny to partially shaded spot in the garden. Younger plants require some protective dry mulch layer against freezing through in winter. Subtropical indigo shrubs shall be kept frostfree in winter at a minimum of some 10°C. Sow seeds flat in any rich, well drained soil at some 20°C throughout the year. Carefully transplant young plants of winterhardy species to the final spot in the garden in autumn or spring. All are USDA Climate Zone 6, unless not stated differently. 20 seeds per package. |
