The Jerusalem artichoke (Helianthus tuberosus), although this is a misleading common name.     It is also called sunroot, sunchoke, earth apple ,native to North America.  It is also cultivated widely across the temperate zone for its tuber for root vegetable.  Best grow in full sun location.  Very easy to grow.  Yellow sunflower like flowers in late summer/early fall, attract bees and butterflies.  USDA Zones:4-9.  Mature size:8′-10′(H) x 2′-3′(W).  Because plant is tall will require support in case of strong wind or heavy rains.  Easy to propagate by seeds, cuttings, tubers/bulbs, corms and dividing the plants.

菊芋Helianthus tuberosus),是菊科向日葵屬的多年生草本植物.原生於北美. 現今世界上有許多國家都有種植做為根莖類蔬菜來食用.  是天然的減肥蔬菜.  它能調節血糖控制糖尿病. 最好是全日照種植.  非常容易栽種.  夏末秋初時開像向日葵般的黃花.  成熟植株蠻高的約8-10呎高,2-3呎寬幅,所以需要支架以防強風或暴雨折損.  容易用種子,扦插,根莖/球根,小球,分株繁殖.

I found its taste after cooking is between potato and water chestnut (Eleocharis dulcis).

煮食的口感介於馬鈴薯和荸薺(Eleocharis dulcis)中間.
