So what do all those Pinyin words mean in this sage’s common name? We’ll give you an answer to the best of our ability in a minute. Meanwhile, we need to note that this medicinal Asian sage has handsome foliage and deep violet flowers.

The flower spikes bloom from summer to fall, attracting butterflies. This sage loves shade and water. Cold and heat tolerant, it grows well in USDA Zones 6 to 9.

Give it rich, well-drained soil similar to the kind where it is found in the wild. San ye shu wei cao grows along the margins of high-altitude forests that border grassy hillsides in Southwestern China. Its dark green, basal leaves are oval-to-heart shaped with pretty, scalloped margins. The foliage mound rises up 24 to 32 inches and spreads about the same distance.

Good uses include plantings in moist areas such as woodland gardens. This perennial sage also shows well in borders, along pathways where you can see it up close and as a groundcover.

Current medical research indicates that chemicals in this plant’s bright red taproots may be effective in battling liver cancer. Similar to many Asian sages, it has a long history of use in herbal remedies. The substances in its roots are used for a variety of medical purposes, including strengthening the immune system, stimulating circulation, soothing the mind, relieving restlessness and improving blood flow to the brain.

We don’t speak Chinese, but after a bit of searching, we discovered that the phrase ‘shu wei cao’ refers to sage. ‘San’ means ‘three’ and ‘ye’ means leaf. So it’s a three-leafed sage, which means that there are three leaves on each petiole.
