Arizona

This is quite effective, with attractive flowers and foliage, growing among rocks on hillsides and forming large clumps over a foot high. The stems are slender and often much bent, the leaves are dark green and thin in texture with toothed edges, rolled back, and the numerous flowers are an inch across, with bright yellow rays and deep yellow centers. This plant blossoms both as an annual and as a perennial.

White
Summer
Northwest

A rather handsome plant, with a stout stem, about two feet tall; the upper leaves more or less downy and the root-leaves rather thick and soft, covered with whitish hairs on the under side. The flower-heads are about three-quarters of an inch across, with a fuzzy, pale yellow center and white rays. This grows in open woods, at rather high altitudes.

Senècio Riddéllii
Yellow
Spring, winter
Arizona

A rather showy plant, from six inches to two feet tall, blossoming both as an annual and as a biennial, after which it dies. The whole plant is smooth and the foliage is green or bluish-green, rather delicate and pretty. The flowers are an inch to an inch and a half across and they begin to appear in winter when there is little else to brighten the desert mesas. This plant is abundant in valley lands, though it has a wide range.

S. multilobàtus
Yellow
Summer
Ariz., Utah, etc.

A rather pretty plant, about a foot tall, with a few small leaves on the slightly woolly stem, but most of them in a rosette at the base. They are smooth, thickish and slightly stiff, about an inch and a half long, and neatly cut into small, toothed lobes. The few flowers are in a loose cluster at the top of the stem and have heads about three-quarters of an inch across, with pale yellow rays and brighter yellow centers. This grows at the Grand Canyon and on the dry plains of Utah and Colorado, at altitudes of about seven thousand feet.
