The best roots in a jar come from the new Illusion Midnight Lace and Emerald Lace Ipomoea batatas. They make a pretty impressive mound of luscious deep burgundy or emerald foliage too. I grew them in the ground and planters and they are by far the best Ipomoeas out there. They will not take over and have grown to about 3 feet by 3 feet this summer. They will be available in garden centers Spring 2010. They proved to be disease, heat, and drought resistant in my zone 7 garden.
********** Updated to say—–this Ipomoea will not be planted in the ground! Sure I could make a million more of them this way but patent means—-PATENT. You can not reproduce this for yourself or for anyone else. I’m using this Ipomoea for a display—period! Just like if you cut flowers for an arrangement. Just wanted to make sure I cleared that up.
By patent, you can not share these cultivars so I root them in a jar for my enjoyment only. They’ve got the prettiest roots I’ve ever seen. They rooted in one day! I’m not kidding. The vase root pictures are from one week’s growth. So not only are they pretty to grow outside but they make a lovely and interesting arrangement inside. It last forever in water.
The leaves are more dramatic than others in the family and have deep cut spaces between the lobes. It’s very graceful.
Just behind the wicker chair you can see Emerald Lace from earlier in the season. It is the same size now( Mid August) as the Midnight Lace from above so you can see how much it grew in once season. I like that it doesn’t get out of hand.
