Our form of Asparagus cochinchinensis comes from Korea's Chuwang Mountain where it grows on very dry rocky acidic (pH 4.3) cliffs. The 7' long twining deciduous stalks are clothed with soft, fleshy, dark green foliage and adorned with tiny white flowers in mid-May (NC). We have found Asparagus cochinchinensis 'Chuwang' to be a wonderful textural element in the garden, best when planted where, like an inebriated partygoer, it can lean on a sturdy friend. In fall, the foliage turns a fabulous bright golden yellow. The tubers of Asparagus cochinchinensis have been used in Chinese medicine for lung and kidney cleansing, and to treat chest pain, cough, bloody phlegm and dry stools...I'm not making this up.
