‘Mailbox Mix’ Heirloom Morning Glory Seeds

Mailbox Mix brings a bit of living history to the garden. Deep blue and pearly white trumpets open fresh each morning over heart-shaped leaves, recalling the vigorous vines pioneer families once carried west to dress new fences and homesteads.

The 8–10-foot climbers quickly turn a mailbox post, arch, or sturdy trellis into a leafy landmark. Although each flower lasts a day, new buds keep unfurling as shortening summer days signal the vines to bloom in earnest.
