Does anyone have experience propagating I. tinctoria from cuttings? Years ago I easily rooted some of the common bedding Impatiens in a glass of water, but this hardy species has been difficult. The larger stems are hollow and rot quickly, and the new growth seems to be too 'soft' to last long enough for rooting.

Very beautiful Impatiens!
I found this info on the web:

Propagation is easiest by taking short side shoots as cuttings, with a bit of a heel. They root easily in water or a suitable light compost in a propagator.

Root them in media like perlite, vermiculite or peat, or combinations thereof. If you root them now, you'll probably need to keep them growing completely frost-free through the winter. If the rooted cuttings don't have time to produce a viable tuber before going dormant, they will likely not return next spring.

Next year, you could bend a branch to the ground and have it root at a node to produce a new plant.

Myriam and Rick,

Thanks for the tips,—I'll try a few both ways. Leaving a heel on the base of the cutting makes perfect sense.
