Delphinium (Delphinium grandiflorum 'Summer Nights') reminds you of days gone by in your grandparent's cottage garden. Create your own with these shorter version specimens and attract hummers and butterflies! Next year, as they scatter their seed in cool-summer regions, you may have more so, plant in full sun with rich, well-draining soil. If your summer days are relatively cool and pleasant, this flower will be a regular fixture in the garden. Grows 10-12 in. tall; 12 in. wide.
