Product Details
Vivid cobalt blue iris flowers with striking yellow and white markings on the outer petals. Iris reticulata 'Cobalt' is particularly easy to force for an early indoor display, and looks sensational dotted through borders or scattered throughout rock gardens.
Height: 15cm (6"). Spread: 10cm (4").
How to grow:
Plant iris reticulata bulbs in late autumn, at a depth of approximately twice their own height. Choose a position in full sun in moist, free draining soil. To create a natural effect, cast the bulbs across the area and plant them where they land. Alternatively, plant bulbs in deep containers of loam based compost such as John Innes No. 2 and grow on in a greenhouse or on cool sunny windowsills for an early indoor display.
Aftercare:
When growing dwarf iris, allow their foliage to die back naturally before removing it in order to feed the bulb for the following spring. Divide overcrowded clumps of dwarf iris bulbs in autumn. Keep pots of iris reticulata just moist during their dormant period and gradually increase watering as growth begins. Caution: All parts of iris are harmful if eaten, and the sap may irritate the skin and eyes. Caution: irritant to skin and eyes, harmful if eaten
