Another canoe plant, awapuhi or Shampoo ginger (Zingiber zerumbet), is related to lena.lena can be harvested at any time of the year. However, I generally like to harvest it when the leaves turn completely brown. I find it has a better and stronger taste at that time. When leaves are green the rhizomes seem more watery and less flavorful. The health benefits are reducing inflammation and joint & muscle pain, and increasing cardiovascular, skin, brain cell function and mood balance.
Alpinia hainanensis belongs to the Zingiberaceae family. This Zingiberaceae herb usually appears on woodside or streamside. It has long slender leaves with asymmetric margins. The strings of white flowers have white corollas and one yellow petal with purple or orange stripes that radiate from core to margin. The colour combination is very eye-catching. This beautiful flower was seen in the Tsing Yi Park, Hong Kong.
