Valley Water, Santa Clara County's water authority, has been a leading influence in helping community members find practical and creative ways to save water. Their headquarters includes a well-maintained and informative drought tolerant demonstration garden. For homeowners that can finally let go of their lawns, Valley Water is currently offering a rebate program to incentivize transitions from lush carpets to conservation gardens with added benefits to the environment (think pollinators and birds, as examples). Valley Water also manages the county's ground water, and this brings me to our plant du jour, Limonium perezii, a.k.a. sea lavender or statice.
Near the corner of Hacienda Avenue and Winchester Boulevard in Campbell, CA, a pair of collection ponds flank the roadway. Not remarkable from a landscape point of view, but seeing them fill with water gives me slight relief, the same feeling I have after a seasonal rain freshens the air. So far this season, the ponds are dry, waiting for the first opportunity to fill. Framing the top embankments of both ponds are a scattering of sea lavenders. I cannot imagine the plants receiving much water amidst the dusty dry field grass; adjacent drought tolerant trees are wilting in this late summer/early autumn heat. Yet, the sea lavenders are thriving, lush with green and just wrapping up their long summer bloom period. Some of the photos below are from this location, including the feature photo above.
While Sunset lists L. perezii as a moderate water user, the University of California, Davis, Center for Urban Horticulture, in partnership with the California Department of Water Resources, categorized this species for needing low water consumption within the Bay Area, as listed in the Water Use Classification of Landscape Species (WUCOLS). Landscape architects use this reference to determine the hydrozone for each plant, so I am inclined to rely on WUCOLS for up to date information...and my observations.
L. perezii is an adaptable species, from moderate to low water use with varying landscape conditions, or as Sunset states, a "first-rate beach plant" (p. 415). Hence the common name. It offers designers a unique opportunity to specify a coarse-textured plant at home in modern, Mediterranean, sub-tropical, seaside, or rock gardens without a lot of fuss. I just planted one in an orange-glazed container in my own garden, apparently wanting to shock my visual senses of color but also a need to observe its behavior first-hand...sort of an upgrade from the days I would specify it on plans but never really grasping its behavior. I will share updates on its performance.
