A. coronaria and some other species succeed well treated as seedling hardy annuals, and others, as A. apennina, A. Robinsoni, A. Pulsatilla, A. dichotoma, and A. japonica, may be multiplied ad infinitum by cuttings of the root.

This agrees with the accepted view that sprouts (which always have wide rings) yield better and stronger wood than seedling chestnuts, which grow more slowly in diameter.
