KNOWLIANS BLACK morning glory are easy to grow. Dark violet flowers (not quite black) with a light red / white center. Every flower is little different than the one next it. The flowers open and close with the sun. There not picky at all about the soil or what they have to climb. These grow a little slower than a common morning glory.They also work as a ground cover on hillsides. They are an Annual that will reseed themselves. Pretty much a carefree plant. They will go strong until the first frost. They don't like a lot of fertilizer, just steady light water about 2 times a week if no rain. Also does well in a med/large container. 25+ seeds per order. Thank you!
