Labiatae Stachys sieboldii Miq.
Source: Magness et al. 1971
The plant is mint-like, up to 18 inches, with ovate to lanceolate leaves. It produces numerous small, slender tubers, the edible part, just under the soil surface. These tubers are white, with crisp flesh which can be eaten raw or cooked. The plant and edible parts are comparable to potatoes, both in culture and exposure to pesticides. The tubers do not store well. Chinese artichoke is not grown commercially in the United States, but may be found occasionally in home gardens.
