Alpinia nutans narrow leaf form

We originally acquired this plant as Amomum cardamomum, but instead, it turned out to be an alpinia. There is some thought that it might actually be A. calcarata, but we're sticking with A. nutans for now. It has proven to be a superb garden plant with its short-spreading rhizome making a 5' wide colony in 6 years. The deciduous rhizomes are topped during the growing season with 3' tall green spikes, adorned with dark green, delightfully fragrant (cinnamon-like) foliage. Since it never flowers in our climate, we use it as a superb, bold, spiky textural plant in the woodland garden.
