# Dudleya lanceolata

Dudleya lanceolata is a succulent plant known by the common name lanceleaf liveforever or lance-leaved dudleya. It is an extremely variable and widely ranging species that occurs from Monterey County and Kern County in California south through Ensenada in Baja California. It is characterized by green to purple lanceolate leaves, red, orange, or less commonly yellow petals, and is typically tetraploid. Despite its diversity, it is quite stable as a species, but hybrids may be discovered with other species of Dudleya, which can make it difficult to discern in areas where numerous species converge.

## Description
### Vegetative morphology

This plant is a rosette-forming succulent. The rosettes emerge from the apex of the caudex, which may be solitary or apically branched, with anywhere from 1 to 7 rosettes on top. The caudex is 1 to 3 cm wide, less than 4 cm long, but is occasionally elongated. The rosettes are 3 to 25 cm in diameter, and typically with 10 to 25 leaves. The leaves are green and sometimes glaucous, but not farinose, shaped oblong to lanceolate, 4 to 30 cm long by 0.5 to 4 cm wide, and 1.5 to 6 mm thick. The tip of the leaf is acute.

### Reproductive morphology

The peduncle is 15 to 95 cm tall, and is 3 to 12 mm wide. The lower internodes are spaced over 5 mm from each other. There are 18 to 40 bracts, spreading to ascending, and shaped triangular-lanceolate to ovate. The cyme is branched 2 to 3 times, and the next branches may bifurcate. The terminal branches are 2 to 25 cm long, and have 2 to 20 flowers on spreading pedicels. The pedicels are 2 to 12 mm long, becoming erect, and are red or green, and not generally pink. The sepals are 3 to 6 mm large, shaped deltate-ovate. The petals are 10 to 16 mm long, 3.5 to 5 mm wide, shaped elliptic to oblanceolate and fused connately 1 to 2 mm. The petals are usually red or orange, and more uncommonly bright yellow to purplish-red, and very rarely green.

The chromosome number is typically tetraploid, 2n = 68 / n = 34, but some plants are occasionally octoploid. Diploid plants in montane regions are in fact Dudleya cymosa. Flowering is from April to July.

## Distribution and habitat

This plant is widely distributed, occurring from Monterey County and Kern County in the state of California, through coastal Southern California and into Mexico, where it reaches its southern distribution near Ensenada in Baja California, at the Punta Banda. It is also found on the Coronado Islands. It is not particularly hardy to the cold, and is typically found where humidity is not too low, by the coast and in north-facing inland locations.

## Cultivation

Dudleya lanceolata is cultivated as an ornamental plant by specialty nurseries, for use in rock gardens, as a potted plant, and a native plant in natural landscaping.
