Achlys triphylla (Sm.) DC.
Sweet after death, Sweet-after-death, Vanilla leaf
Berberidaceae (Barberry Family)
Synonym(s): Achlys triphylla ssp. triphylla
USDA Symbol: actr
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.
