Ladies’ Tobacco, California Rabbit Tobacco, California Everlasting
Description (Jepson, PlantID.net)
- Eudicots are a major lineage of flowering plants; see family for general characteristics
- Sunflower Family (Asteraceae)
- Annual or biennial herb
- Mostly narrow, oblong to lance-shaped, with wavy edges
- May attach directly to stem (sessile)
- Sometimes with woolly, glandular (sticky) hairs
- Inflorescence (flower arrangement) of branched, open (loose) sets of flowerheads
- Each disciform head (see Sunflower family) is tightly packed with minute, yellow flowers
- 100-140 female (pistillate) peripheral flowers with reduced or missing rays
- 7-12 bisexual central disk flowers
- Flowerheads are surrounded by rows of whitish, paper-like phyllaries (vase-like floral bracts, collectively called the involucre), like the wrapping around a flower bouquet
- Ovary inferior (below the attachment of other flower parts)
- Fruit is an achene (a single-seeded, dry fruit that does not split open) with a pappus of bristles
- Height 2-4 ft.
- Native to California
- Grows in forests, foothill woodlands, and chaparral
- See Calflora for statewide observations of this plant
- Outside California, grows from Oregon to Baja California, Mexico
- Grows at elevations between 200 and 2,600 ft.
Uses (San Mateo County Parks prohibits removal of any natural material)
- Visited by insects
- Larval food source (host) for the American painted lady (Vanessa virginiensis) butterfly
- Native people
- Used an infusion of the plant to treat colds and stomach pain
- Leaves were used as a poultice for burns, bruises, and cuts
- Pseudognaphalium (soo-doe-na-FAY-lee-um) – literally, false Gnaphalium, referring to a superficial resemblance of plants in this genus to those in the genus Gnaphalium
- Gnaphalium, from the Greek gnaphalon, “a lock of wool,” referring to the woolly leaves
- Cudweed – commonly used worldwide for a number of plants in the Sunflower family, especially those in the genera Pseudognaphalium and Gnaphalium
- Aromatic leaves deter browsing
- Some people smell maple syrup; others smell cumin: judge for yourself by rubbing the leaves – no need to pick them!
- Bristles on fruit help dispersal by wind or animals
- Floral bracts (phyllaries) remain on the plant long after flowering and open outward as they dry, appearing like petals; thus, the flowers seem to be “everlasting”
- Everlasting is another common name for plants in this and related genera, collectively called the Everlasting tribe
- What distinguishes the genus Pseudognaphalium from the related genus Gnaphalium (not found in Edgewood)?
- Pseudognaphalium species are generally erect plants that grow in dry habitats
- Gnaphalium species are low-growing, spreading or prostrate plants that grow in moist, often coastal habitats
- May be confused with 4 other species of cudweed at Edgewood; of these, cotton-batting plant (P. stramineum) and weedy-white cudweed (P. luteoalbum) are the most frequently seen
|California Cudweed||Cotton-batting Plant||Weedy-white Cudweed|

|Woolly Hairs||sometimes||yes, whole plant densely woolly||yes, whole plant somewhat woolly|
|Flowers||branched, open (loose) sets of flowerheads||usually a single, dense, terminal (top) cluster of flowerheads||long stems with red-tipped flowerheads|
