Present on Pacific Islands?  yes

Primarily a threat at high elevations?  no

Common name(s): [more details]

English: seashore vervain

Hawaiian: ha‘uōwī, oī, ōwī

Mangarevan: vere pene

Spanish: verbena

Habit:  herb

Description:  "Erect or ascending perennial herbs 4-20 dm tall, sometimes somewhat woody toward base; stems few to many-branched, glabrous or sparsely strigillose.  Leaves decussate, lanceolate to oblanceolate, 3-10 cm long, 1-1.5 cm wide, both surfaces finely scaberulous, margins coarsely serrate, apex acute, base attenuate.  Flowers numerous in several slender, terminal spikes 3-12 cm long, sparsely short-pilose throughout, bracts subulate, shorter than to as long as the calyx; calyx sometimes purple, 1.5-2.3 mm long, short-pilose; corolla usually blue, occasionally pale blue, lavender, or purple, ca. 2-3 mm long"  (Wagner et al., 1999; p. 1325).

Habitat/ecology:  In Hawai‘i, "occurring in dry to wet, disturbed habitats, 10-2,280 m" (Wagner et al., 1999; p. 1325); "displaces forages in pastures and native species in disturbed forest sites"  (Motooka et al., 2003).  Moist uplands in the Galápagos Islands (McMullen, 1999; p. 276).  "In Chile this species grows in the following environmental conditions:  Low altitude, interior valleys; coastal mountains, 500-2000 m; coastal areas, 0-500 m.  Somewhat dry areas where the drought may last 3-5 months, precipitations of 400-800 mm. are concentrated in winter; dry, arid areas, with long drought periods of 6-10 months, precipitations of 100 mm-300 mm. are concentrated in winter.  Fully exposed to the sun, level areas or slopes facing north"  (Chileflora).

Propagation:  Seed

Native range:  Mexico through Central America to South America, widely naturalized (Wagner et al., 1999; p. 1325).

Comments:  Probably not native to the Galápagos Islands, possibly introduced, per Charles Darwin Research Station.

Control: 

Physical:  "Goats will not browse on seashore vervain (An Peischel)"  (Motooka et al., 2003).

Chemical: "Sensitive to foliar application of 2,4-D"  (Motooka et al., 2003).

Additional information:
Excerpt from the book "Weeds of Hawaii‘s Pastures and Natural Areas; An Identification and Management Guide" (Motooka et al., 2003). (PDF format).
Photos and other information from Chileflora.

Additional online information about Verbena litoralis is available from the Hawaiian Ecosystems at Risk project (HEAR).

Information about Verbena litoralis as a weed (worldwide references) may be available from the Global Compendium of Weeds (GCW).

Taxonomic information about Verbena litoralis may be available from the Germplasm Resources Information Network (GRIN).
