IntermediateAgave shawii
An agave from southern California to Baja California. Native to coastal rocky areas with notable salt tolerance. Broad green leaves with reddish spines make it highly ornamental.
About
Agave shawii is a medium-sized agave native to coastal bluffs and dry scrublands from southern California to northern Baja California. Its broad, dark green to deep green leaves are notably thick and glossy, lined with large, conspicuous reddish-brown marginal teeth spaced at intervals. Mature rosettes reach 60–100 cm in diameter and tend to form colonies by producing offsets. As a coastal species, it is adapted to fog and maritime moisture, tolerating somewhat more humidity than most agaves. Wild populations in California have declined, prompting conservation concerns in some areas. Suitable for both container and landscape planting, it captivates enthusiasts with its deep leaf color and bold dentition.
