Dutch Iris Professor Blauw - 4 bulbs

Iris hollandica 'Professor Blauw' - Dutch iris

APPEARANCE :  Tall growing bulb plant with strap-like leaves and deep blue flowers with golden spots.
USE FOR : Plant below deciduous trees, in mixed garden beds,or group closely in pots for bright spring flowering colour. Dutch iris are bred for cut flowers so cut some and bring them indoors!
CLIMATE : Frost hardy to sub-tropical. Tolerates dry periods once established.

PLANTING :Dutch irises are very tolerant of whatever soils they are planted in. Plant bulbs with the narrow end facing upward, cover with a good layer of mulch to help regulate soil temperature.
CARE: Once planted, water the soil to set the bulb in place. An occasional light watering is all that's needed until the first flowers appear. Water and feed weekly or if the soil becomes dry, give a good deep water (bulbs are generally at least 5 cms below the surface). Once flowering is finished leave plants to die back, it's not the prettiest sight but don't be tempted to trim the yellowing foliage. The nutrients are being drawn back into the bulbs for next year. When the bulbs die back completely remove spent foliage and leave in place for next season. Or remove for storage - gently dig up bulbs, wash soil away using water and a soft brush for stubborn spots. Place bulbs in a cool shady spot to dry, then store in a dark, well ventilated room. Paper bags are ideal, remember to label each variety!
Contains 4 bulbs.
