Hesperocyparis macnabiana
MacNab Cypress is native to dry, open, slopes, usually on serpentine, in chaparral and woodlands of Northern California. Fast growing tree or large shrub, 15 – 40 ft. tall, often with multiple trunks and a spreading crown, growing wider than it is tall. The pleasantly pungent, grey-green, foliage smells like gin and is arranged on flattened branches, giving it a somewhat lacey appearance. The bark is rough and furrowed and the cones are spherical and persistent. Plant in full sun with good drainage and little to no summer water once established. Deer resistant.
Hesperocyparis sargentii
This cypress makes its home in serpentine pygmy forests from Santa Barbara to Mendocino Counties. While often dwarfed in its native terrain, this species can grow quite happily off of serpentine and may reach up to 60 ft. tall. The small, dark-green, scale-like leaves form a bushy canopy against the gray-brown trunk. A good medium-sized tree for hotter inland areas, but will also tolerate coastal conditions. The sargent cypress can grow fairly rapidly, useful as a high privacy screen or wind break. Plant in full sun to light shade and water occasionally. Will be very drought tolerant once established. Needs good drainage. Deer resistant.
Hesperoyucca whipplei
Bold and dramatic architectural accent plant native to southern California coast and mountains south to Baja. Forms a dense rosette of rigid silver-blue blades, 2 foot tall by 3 - 4 foot wide. Each blade has a VERY SHARP tip and careful thought should be given to its placement to avoid injury. Plants can take 3 to 15 years to bloom with impressive stalks rising 6 foot or more above the rosette with drooping, creamy white, bell shaped, fragrant flowers. The flowering rosette dies after blooming often being replaced by vegetative offsets. Best with good drainage in full sun to light shade. No water once established. Deer resistant
Heteromeles arbutifolia
Toyon is a handsome native evergreen shrub 6 - 10 ft. tall and wide. Sun to part shade, drought tolerant. Clusters of lacy white flowers bloom in summer and areattractive to pollinators.
