Nursery contributed plant descriptions

Colchicum 'The Giant' is one of the tallest, easiest to grow, and floriferous of the autumn crocus producing up to 10 lavender-pink flowers per bulb. The lush, green leaves emerge in spring into attractive mounds and go dormant in summer. The flowers arise without leaves in late summer or fall. Grow in fertile, well-drained soil. Our bulbs are extra large grade bulbs compared to those commonly available elsewhere. The photo is a mass planting of 'The Giant' at Niagara Parks taken in early October growing through Ceratostigma plumbaginoides or blue leadwort.

One of the fall croci, these rank with cyclamen as must-haves for the autumn garden. Anywhere from late August into November, from bare earth come 4-6" crocus flowers of pink with a pale lilac throats. In late fall, though much later in colder climates, the coarse textured leaves appear growing vigorously until mid spring. A fairly quick multiplier, they are great under shrubs or in any neglected area of the garden in dappled shade to full sun. Frost hardy in USDA zone 5.
