Conicosia pugioniformis

Synonyms: Mesembryanthemum elongatum

Common names: narriow-leafed iceplant; false iceplant; conicosia

Conicosia pugioniformis (narrowleaf iceplant) is a succulent perennial (family Aizoaceae) found on dunes, beaches, scrub and grassland along the central coast of California, especially in Santa Barbara and San Luis Obispo counties. Narrowleaf iceplant does not form mats like other invasive iceplants (i.e., Carpobrotus edulis or C. chilensis) so its impacts are less severe. However, it can become locally abundant and crowd out native plants, especially in dune habitats. Narrowleaf iceplant reproduces by seed, and buried root crowns can resprout after aboveground plant matter has been removed.
