Marsh woundwort (Stachys palustris), is very similar to Chinese artichoke, but with a more earthy flavor. Tubers reach a maximum of about 4 inches in length, although more typically about half that. Not particularly heat tolerant, but handles chilly weather better than Chinese artichoke. Keep it well watered for the best yield. A good plant for swampy areas, although you might want to plant it in buried containers to keep it from running away. Plant or pot immediately on receipt; they don’t keep very well out of the ground.
There are a number of different populations with different ploidy levels. This type is of North American origin and we believe that it is tetraploid, although we’re not entirely sure.
5 rhizome segments, two to three inches in length
