Water Lilies are the centerpiece of the water garden. The colorful flowers are produced throughout the growing season and sit above various shades of foliage. Dwarf to large varieties are available for everything from small containers to large ponds and lakes. Water Lilies love sunlight, heavy loam soil and appropriately sized planting containers (the more generously sized the better) along with plenty of slow release fertilizer will assure strong healthy plants with generous flowering. Zone 3 as long as the crown is below the freeze line.
