Morning glories are popular annual vines for growing up a fence, arbor, trellis or arch. There are also selections that grow well in containers on a deck or patio. The heart-shaped leaves form on quick growing stems reaching up to 15 feet tall. They can become a mass of leaves and flowers by late summer. The flowers, in colors from white to purple, begin forming in mid-summer and continue until frost. As the name implies, morning glory flowers open in the morning and close in the afternoon. The large, colorful flowers attract butterflies and hummingbirds. Morning glories also self-sow readily so they will surprise you each year as new plants pop up in different parts of the garden.
Dwarf morning glories prefer light, sandy soil with good drainage. Amend the soil by incorporating compost, which helps any soil type, breaking up heavy clay soil and improving water retention in sandy soil. Keep the soil moist until the plants are established. Once established, dwarf morning glories tolerate dry conditions. Allow the top inch of soil to dry out between waterings, but don’t allow the plants to wilt. Dwarf morning glories tend to produce more flowers in poor soil, so fertilizer is typically unnecessary.
