Early Blue Spring Flowers

Gardeners look eagerly for color in an early spring garden, and blue flowers have a special appeal. Most early flowers are bulbs, corms or rhizomes, which you need to plant in fall. The varieties listed here are known for their beautiful shades of blue; some are fragrant.

Varieties

Phlox Divaricata
Following are some varieties of early blue spring flowers: grape hyacinth (Muscari armeniacum); hyacinth (Hyacinthus orientalis); windflower (Anemone blanda); crocus (Crocus chrysanthus, C. sieberi); Siberian squill (Scilla siberica); English bluebell (Hyacinthoides non-scripta); Spanish bluebell (Hyacinthoides hispanica, Scilla campanulata); dwarf iris (Iris reticulata); wild phlox (Phlox divaricata); heartleaf brunnera (Brunnera macrophylla); and glory of the snow (Chionodoxa luciliae).

Hardiness Zones

U.S. Department of Agriculture Hardiness Zones Map
Most spring bulbs thrive in Zones 4 through 8 of the U.S., with low temperatures between -20 and 20 degrees. The U.S. National Arboretum website lists hardiness zone maps (see Resources).

Fragrance

Spanish Bluebells
Grape hyacinth, bluebells, and dwarf iris have delicate scents; hyacinths have a strong, sweet scent.

Maintenance

Spring bulbs need little care, other than a sustained period of cold temperatures for healthy root development. The Netherlands Flower Bulb Information Center website is a good guide for bulb care.

Purchase

Many bulbs are shipped from the Netherlands to the U.S. for sale; the National Arboretum website has a good list of retail sources. Bulbs are shipped in the fall; plant them promptly for best results.
