Cardamine quinquefolia Asia (aka: Thelypteris penangiana) Pronephrium penangianum

(aka: Thelypteris penangiana) Pronephrium penangianum is our 2015 Plant Delights/JLBG introduction of an amazingly vigorous form of the tropical-looking Chinese Peng fern

300' elevation when we saw a patch of Zantedeschia aethiopica growing in a wet seep along the steep mountain cliffs

and offering our extra 4-year-old seed grown plants for gardeners who also wish to experiment

as well as summer flowering when many spring perennials have finished flowering or gone dormant

Cardamine quinquefolia Asia (aka: Thelypteris penangiana) Pronephrium penangianum(aka: Dentaria quinquefolia) Cardamine quinquefolia is a lovely spring ephemeral groundcover that can be found growing wild in slightly moist beech oak forests around the Black Sea, stretching from Romania to Iran. In our garden, Cardamine quinquefolia has formed a stunning 3' wide patch in four years. The deeply lobed fresh green foliage emerges in February, and is smothered, starting in late February with 6" tall stalks of small mauve flowers. By
