DRIMIA MARITIMA, (Urginea maritima, Sea Squill)
Drimia maritima is a Mediterranean climate adapted bulb of up to 10 lbs. native to Northern parts of Africa, hardy in USDA Zones 8-11. In Southern California Drimia maritima can grow in areas with less than 10 inches of rain per year without irrigation, although it can take much more. Problems only occur with frequent (more than weekly) summer irrigation or rains. Tolerates heavy soils as well as growing in pure sand. Full sun is preferred, but shade for up to one third of the day will also work. All parts are poisonous, but are so bitter and difficult to consume without vomiting that poisoning is almost impossible. Rodents and deer will not eat this plant.
In Fall, Sea Squill sprouts a lush agave-like crown of foliage 2-3 feet in diameter and 18-30 inches tall. Foliage persists until soil moisture drops in early summer. As days shorten in late Summer the leafless crown sends up a bloom stalk up to 6 feet tall, sporting hundreds of pinkish white eremuris-like blooms. During this stage, the bulb is dormant, and can be dug for displaying the blooms (which are also exceptional as cut flowers.) Bulbs do not need to be dug or divided and can remain in the same location for centuries.
Drimia maritima has been used in landscapes (including on roofs at The Getty,) in the cut flower trade, and as an emetic in ancient Rome. Suitable companion plants including many of the California sages, Muhlenbergia, tall bearded irises, restios and most cacti and succulents.
It is useful in irrigated and non-irrigated landscapes and slopes where fire danger is present. Drimias extensive roots and winter foliage prevent erosion and suppress weeds. Foliage is dormant during the fire season allowing for easy brush mowing/cutting.
