Comments:  "In Hawai'i, snapdragons are grown as winter annuals that thrive best where temperatures are cooler (i.e., at higher elevations on Maui and the Big Island). Young plants are usually purchased in flats from nurseries, although seeds are readily available through garden shops or by mail." (A Tropical Garden Flora, p. 525)

Control:  (control info not known by PIER)
