    How to Plant Knowlians Black Morning Glory

    When to Plant Morning Glory Seeds

    Seeds can be directly sown once soil temperatures are 65 degrees or above, or started indoors 4-6 weeks before the final frost date for your area.

    Where to Plant Morning Glory Seeds

    Morning Glory plants prefer full sun so be sure to pick an area that has direct sunlight for 6-8 hours.

    How to Plant Morning Glory Seeds

    Seeds may be scarified, but not a requirement. To scarify, you may nick the seeds with a knife, or rub the seeds with sandpaper or a file. Then soak the seeds overnight. Plant seeds 1/2 inch deep and provide 8-12" spacing between plants.

    Once vines reach 6 inches, provide trellis support unless planted in hanging planter in which case you can leave it to spill over.

    How to Care for Morning Glory

    Water weekly at first or when the soil looks dry. Once established, only water as needed. Remove any spent blooms as they appear and at the first sign of killing frost, cut back dead vines.

Easy growers, lighter than I thought

I, too, wish I could post a photo. They were a bit slow to germinate and get going in Colorado, but after the first set of true leaves came out they are climbing super fast! I just had my first blooms on each plant this morning and they are rather shocking blue-violet -- I thought they'd be more of a maroon per the image, but they are like ultramarine with a delicate pink center. I still love them, just unexpected color. Can't wait for the chocolate ones to start blooming!

Really beautiful. I wanted to post a picture but I don't see how. I grew them all over my house. They were more of a purple color but I find that most black flowers are. I live in the north country, zone 4 upstate ny. Extremely cold winter. They re seeded themselves and I have so many popping up this year! This fall I will collect the seeds.
