Achlys triphylla


Sweet after death, Sweet-after-death, Vanilla leaf


Berberidaceae (Barberry Family)



Achlys triphylla (Sweet after death)
Bransford, W.D. and Dolphia
This perennial is a spreading ground cover. Large leaves, divided into three leaflets, rise at close intervals from underground runners and are long-lasting. Stalks, less than 8 in. high, produce numerous tiny, petalless, whitish flowers clustered together in a narrow, fluffy spike. Pairs of low slender stalks grow in patches, one stalk actually a petiole, having at its tip a round leaf blade with 3 broad, fan-shaped leaflets; the other stalk ending in a narrow spike of small white flowers. The dried plants have a vanilla fragrance.

The large, 3-part leaf is unusual, like that of its only close relative, California Vanilla Leaf (A. californica), found nearer the coast, but which generally has 6-8 (rarely up to 12) teeth on the central leaflet.
