Germination
-
Moonflowers are not tolerant of frost and cold weather. Moonflower seedlings emerge after soil temperatures reach 65 degrees.
Leaves
-
Moonflowers are dicotyledons, according to the U.S. Department of Agriculture. This means that two seed leaves are visible when the plant first emerges from the soil. The leaves have two pointed lobes, which later become heart-shaped and grow up to six inches wide.
-
Stem
-
Moonflowers are vining plants. Like all members of the morning glory family, the stem of the seedling has a reddish hue that turns brown and woody as it matures.
Growing Habit
-
Moonflower seedlings have an upright habit when they first emerge. As the plant gains height, the vine begins to twirl clockwise.
Environment
-
Moonflowers will not grow well in heavily shaded areas. Seeds will germinate in low light environments but will not thrive as they mature.
Life Cycle
-
In zones 7 and below, moonflowers are annuals that have to be planted from seed each year. Unless you have planted moonflower seeds, unidentified seedlings that emerge are not likely to be moonflowers below zone 7.
