Some varieties are considered as noxious weeds in some areas, while others are well known as morning glories.  These fast-growing vining plants also make lovely additions to the garden if kept in good condition.

Morning glory plants produce beautiful funnel-shaped blossoms of various colors like blue, white, yellow, red, and purple with heart-shaped leaves.

Blooming occurs anywhere starting from May through September, opening in the morning and closing in the afternoon.  No wonder they are known as morning glories.

They are fast-growing annual vines that grow and bloom within a short time.  They rapidly grow up to 15 feet or more a season.  They are in the same botanical family as sweet potatoes although they don’t produce edible roots.

Their intensely colored trumpet-shaped flowers have a mild fragrance that butterflies and hummingbirds love to hang around.

Their buds are twirled up tightly and only unfold when the sun shines on them in the morning; thus, their unique name.

These flowers are native to Central America and Mexico.  These vines grow by clinging to nearby support with their tendrils.

You can plant the morning glory seeds a month before the last spring frost.  Some gardeners find these plants too aggressive, if so you can pull out the unwanted seedlings easily.

Morning glories do well in moist but well-drained soil. It must have a neutral pH of 6.0 to 6.8.  Though these flowers will grow anywhere, they bloom better in soil that is not too rich in organic matter.  If you think your vines are struggling you can always amend your soil with some organic manure.

Regular watering your morning glories can kick start their blooms by mid-summer.  However, many times these plants are slow to begin setting flowers.  If you want to speed up the flowering time of morning glories you can try sowing the seeds earlier in the spring by sowing them indoors or scattering them on the frozen ground and even on snow.


Provide your plants with regular water, at least an inch per week.  You can also mulch around the roots to keep the moisture.  The most important season to water is during the plant’s growing period.  You must keep watering to keep the morning glory leaves green and healthy for better blooms. Once it’s established you can slow your watering schedule.


Morning glory flowers thrive in a spot that gets full sun. The flowers will only open when they are in direct sunlight.  Expose your flowers daily to full sun for at least 6 to 8 hours a day.  They will in turn give you the longest amount of bloom time. If they are growing in a spot that doesn’t get sun until the afternoon, they might not bloom.


If you planted your plants using compost or organic manure, you don’t have to feed them with fertilizers. However, if not, you need to feed your morning glories with a low nitrogen fertilizer at least every 4 to 5 weeks throughout their growing period. If you notice your plants are not blooming, try a fertilizer blend that is high in phosphorous.
