Climbing Vine
Blue Star Morning Glory (Ipomoea tricolor) is a vigorous annual vine that climbs 6 to 10 feet tall, producing an abundance of blooms from summer through fall across hardiness zones 2-11. This heirloom cultivar takes 84 to 98 days from seed to first flower, rewarding patient gardeners with reliable, prolific blooming in full sun. The vines are narrow and columnar, making them ideal for trellises and vertical growing spaces where they'll attract pollinators throughout the season.

Blue Star Morning Glory germinates reliably within 5 to 14 days when seeds are nicked, filed, and soaked before planting, giving gardeners quick success even as beginners. The vines climb steadily in warm weather, thriving on moderate water and modest fertility, and produce flowers continuously from mid-summer through the first frost. This heirloom variety has survived decades in cultivation because it's genuinely easy to grow and genuinely rewarding to watch.
Blue Star Morning Glory is grown as an ornamental vine, valued for its ability to cover trellises, arbors, and vertical garden structures with living color across the growing season. Gardeners use it to screen unsightly areas, create natural privacy barriers, and add height and movement to flower beds and borders.
Sow seeds indoors about 4 weeks before your last frost date in pots kept at 65 to 80 degrees Fahrenheit. Nick or file the seed coat and soak seeds in water for 8 to 24 hours before sowing to improve germination rates. Cover pots with a humidity dome to retain moisture until seedlings emerge, which typically occurs within 5 to 14 days.
Transplant seedlings outdoors about two weeks after your last frost date, once soil has warmed and frost danger has passed. Space plants 1 inch apart and provide immediate trellis or support structures for the vines to climb.
Direct sow seeds two weeks after your last frost date, nicking or filing the seed coat and soaking in water for 8 to 24 hours beforehand. Sow at a depth of 1/4 to 1/2 inch and keep soil consistently moist until germination occurs.
