Dudleya anthonyi - Anthony’s liveforever

This spectacular white-leaved dudleya, named after one of the island’s earliest botanical visitors, is certainly one of the most conspicuous plants on the island. The white rosettes grow abundantly and many very large specimens (up to 8 ft high and more than a foot across for a single rosette!) occur on the island. This species is entirely restricted to the eleven cinder cones of the San Quintin Volcanic Field, growing nowhere else in the world. Its close relative, chalk dudleya (Dudleya pulverulenta,) is more widespread on the mainland. Plants on the island appear to be bigger than those on the adjacent mainland. Hummingbirds pollinate the striking red flowers that appear in clusters in mid-summer. Due to its very restricted distribution, this plant is considered rare. The flowering stalks of dudleyas can be snapped off, the outer skin peeled away, and the center chewed for moisture; this species is particularly succulent.

Dudleya cultrata - liveforever

A narrowly endemic Dudleya of the California Floristic Province portion of Baja California, this green-leaved dudleya is found throughout the island, usually in smaller numbers than the abundant white dudleya (D. anthonyi.) At present (2009), these plants appear to be stressed on the island and the leaves often appear speckled red. Individual rosettes tend to be fairly small (up to 5” diameter on average). Yellowish flowers appear in summer. Due to its restricted distribution this plant is considered to be rare.

Dudleya x hybrid: D. anthonyi & D. Cultrata

Sometimes difficult to distinguish due to their variable nature, there are several natural dudleya hybrids on the island (D. anthonyi x D. cultrata) Dr. Reid Moran studied these unusual plants in 1951. Coloration is usually distinct, with the leaves often taking on a pinkish hue. Plants are intermediate between the green and white Dudleya species, both in size, color and flowering times. These interesting plants are mostly located in the southeastern portion of the island and are found in small numbers. We mapped each plant that we encountered and estimate a population size of around fifty individuals.
