Hi Gerry,
I'm curious where you read this? I was under the impression that Baptisia is very difficult to propogate other than from seed.

I dug up 5 small baptisia from the edge of the forest on my property, and they took a couple weeks but 4 of them are sprouting new leaves, looking good so far.

Gerry, it may be too late now, the window of opportunity for baptisia cuttings is somewhat short. I tried 4 cuttings as an experiment late last Spring and had one b. Chocolate Chip that emerged this season and is thriving.

Another propagation method that is a fairly recent development for baptisia, is stem cuttings. Most baptisias root easy in spring when the growth is soft, the success rate drops off to zero as the plants harden. Cuttings should be dipped in a rooting hormone, and then kept in high humidity until they root...usually about 8 weeks.

Another problem with cutting propagated baptisias is one of overwintering. If the cutting grown plants do not develop enough starches after they root, they will not form new growth buds for the following spring. In spring, a mass of roots will simply fail to send up any foliage. We have found that after rooting, plants that are placed directly into the ground seem to develop growth buds faster than container grown plants. The other option is to keep newly rooted containerized plants in a warm greenhouse or on a windowsill until the new buds develop at the base, and they can be allowed to go dormant.
