If you love blue flowers, then you need to add this beauty to your garden. Sturdy stems of iridescent blue flowers appear in spring from mounds of fern-like green foliage. These hardy bulbs are happy blended into many areas of the garden, a good option for patio tubs and planters. Staggered plantings a month apart will provide an extended flowering season. Sun or part shade. Space between plants 10-15cm.
