Grown for its summer-long display of deep blue, funnel-shaped flowers, 'Blue Enchantment' is a selection of Convolvulus tricolor, a low, mounding, short-lived perennial from the Mediterranean Basin. It is usually cultivated as an annual.
Narrow oval or lance-shaped leaves cover the bushy plant. The short-lived flowers have five fused petals which spread at the tips, forming a pentagonal "face." An egg-yolk-yellow throat surrounded by a starburst of radiating white feather-marks ornaments the center of each bloom. The flowers remain open for most of the day. Hummingbirds and butterflies visit the blooms, which continue to appear from early summer into fall.
Grow this dwarf morning glory in full sun in well-drained, moderately moist soil. Start it from seed sown in cell packs in early spring. In milder climes sow seed directly in the garden in late winter (or in late fall for spring bloom). Nick the hard seedcoat or soak seeds overnight in water to promote germination. This is a lovely and interesting bedding plant for sun. It also works well in pots and hanging baskets. Powdery mildew can be problematic in regions with hot humid summers.
