Baptisia can also be rooted from stem cuttings. Cuttings are genetically identical to the plant that provided them, which ensures the preservation of desirable characteristics such as unusual stem or flower color. Be aware that many new Baptisia cultivars are patented and cannot be legally grown from cuttings or other clonal propagation methods.
Most baptisias root easily in spring when the growth is still relatively soft, but the success rate drops as the stems harden. Good cutting material can generally be found in late April to early May. Cuttings should be taken so that at least one set of leaf buds can be inserted below the potting mix surface. Dip cutting in a rooting hormone and insert into a mix of 3 parts composted bark to 1 part peat. Keep humidity around cuttings high with a supported plastic tent. Cuttings should root in about 8 weeks.
Division or transplanting of Baptisia is difficult because of their deep woody root system and should be avoided unless absolutely necessary.
