How to Grow Dwarf Morning Glory (Convolvulus Tricolor)

Unlike their taller, lankier cousins, most dwarf morning glories grow just 1-2 feet high. These annuals (meaning they grow just one year) have the same pretty, trumpet-like flowers in blues, purples, pink and white with distinctive markings.

Instructions

    • 1

      Choose a type of dwarf morning glory carefully. Most offered in reputable seed catalogs are fine, but Convulvulus arvensis spreads invasively and becomes a pest.

    • 2

      Soak seeds in warm water 24 hours before planting.

    • 3

      Plant from seed directly in the soil after your region's last frost date. Plant about 1/8-inch deep.

    • 4

      Start seedlings indoors, if desired for earlier bloom, five to six weeks before the last frost date. Transplant outdoors after the last frost date.

    • 5

      Fertilize lightly, if desired, two or three times during the growing season. Dwarf morning glory isn't a heavy feeder.

    • 6

      Keep reasonably well watered. However, this warm-season annual likes hot weather and suffers only in very dry conditions.

    • 7

      Pull up and discard plants in autumn, once frost has felled the plants.
