Zantedeschia aethiopica    CALLA LILY    blue house    with cactus and stairs    old fence    purple    I like purple!    a clumping winter evergreen perennial (unless cut back by frost), dormant and deciduous in summer, easily recognized by its large, dramatic, rather tropical looking arrow-shaped dark green leaves to 3' and giant funnel form white flowers on stalks to 4'. Full sun to mostly shade. Tolerates a complete lack of summer watering, going dormant and reappearing with winter rains but thrives under conditions of ample availability of water. Does best in soils that retain good moisture in winter. Invasive in wet, boggy habitats and naturalized in many places in coastal Central California. It seems to do very well under cool summer conditions. Blooms initiate with short days. A dramatic, first class and expensive cut flower! Hardy to around 15-20F. South Africa. Araceae. rev 3/2004

'White Giant'   garden    closeup   'gi-normous' fits this plant, with flower stalks up to 6' or more, and large, white-spotted green leaves to 4' making for a robust presence in the garden. Our collector strain features better-than-normal white markings on the leaves. This is a short day, cool weather species (unlike the long day flowering, colored hybrids), emerging in fall, blooming in winter, and going dormant with late spring heat and drought. Summer watering will keep it evergreen. Likes average soils and regular watering but will tolerate poor drainage and boggy, constantly wet conditions.Sun or part shade near the coast, more shade inland. Protect from severe cold. Sunset zones 5-9, 12-24/USDA 7.  rev 2/2011

Zauschneria   CALIFORNIA FUCHSIA   being related, and also known as Epilobium. We retain this designation in homage to the humble, hardworking and hopelessly happy hummingbird, which is the pollinator for this group, as opposed to the bees that work the Fireweeds. These grow as low (a few inches) to moderately upright (30"), winter deciduous perennials, spreading by underground runners. They bear extremely showy terminal sprays of tubular, brilliant red flowers to 1 1/2" long in summer and early fall, often on dry, rocky, unirrigated slopes and roadcuts. The best forms have strikingly silver, grey or almost white foliage. You would think this would be the archetypal California perennial, intolerant of much cold or summer watering. But my Aunt Pat in Connecticut planted one and it just about took over her garden to the point that she dug it all out. Proved to be winter and summer hardy there. Go figure! Just goes to prove you have to kill it to be sure it won't grow for you. They do well in containers. Sun to part shade, little or no summer watering when established. Onagraceae. rev 10/2013

'Everett's Choice'  flower spikes grey-green foliage, tall, open spikes of bright red flowers. To 1' tall by 3' across. rev 2/2016

'Schieffelin's Choice'
 reddest red   this form grows as a low, arching, tight mound of short upright stems with silver grey foliage. Typical spectacular red orange flowers. To oOnly 6-12" tall and 2-3' wide, it is a real attention getter spilling over pots, or walls, or covering the ground. Sunset zones 2-11, 14-24/USDA 6.

'Sierra Salmon'  (Z. canum)  flowers  grey green foliage, light salmon orange flowers in summer. Upright, to about 18" or more and spreading. rev 202016

'Select Matthole' (Z. septentrionalis)   closeup    habit    my favorite, along with 'Cloverdale' and that amazing, white-foliaged thing ('Calistoga'?). This is the most silver variety, and the pickiest about siting. Forms a dense, low, mostly flat clump of very broad, silver leaves, to 2 wide, 8" tall topped with those startlingly brilliant red flowers beginning in summer. Needs very good drainage, especially in wet-winter climates, but tolerates ferociously hot, dry climates. Found on a dark, south-facing roadcut somewhere in the interior of Northern California by Ray Collette, introduced by UC Santa Cruz. rev 2/2019

seedlings (from 'Silver Select' parent)     seedling variation    flowers (parent)    wonderful plant (parent)    so why grow seedlings? Because we like Jeff Rosendale's original selection so much we decided there might be something else good hiding in those chromosomes. These seedling plants all have the same spectacular summer and fall show of intensely red tubular flowers that draw annoying numbers of hummingbirds. All differ modestly, in size, habit, leaf size and color on both juvenile and mature foliage, and stem color. All are looking shorter than the often-tall parent so far, and a few are even looking like horizontal growers. Pick the one you like, name it after someone (me?) and bingo! you have your own, personal plant variety! As you stroll visitors around your garden you can oh-so-casually mention "oh and that Zauschneria there is another one of my numerous introductions." You might even end up famous. Full to half sun, moderate to zero summer watering when established, depending, average to good drainage. A good container plant for medium size pots, or in larger pots combined with other varieties. USDA zone 6-7.  *New for 2017!*

'Wayne's Silver' leaves and flowers  taller and more upright than 'Select Matthole,' leaves narrower and not quite as silvery, but very close. Forms a very dense dome of flowers and foliage, typical, intense red flowers can be hard on the eyes. rev 2/2016

Zoysia tenuifolia   KOREAN ZOYSIA GRASS  Richard Josefson's Yard - May    Richard Josefson's Yard - November   an evergreen to deciduous, very slowly-creeping grass, tight, dense and extremely fine-textured but also very tough and durable. It is much like a larger, darker green version of Scleranthus biflorus, and will eventually  form similar convoluted, brain-like swells and mounds. It is strictly a long-day grower, and shuts down from about October 1 through around March 10, becoming darker in color as well. Outstanding for use between stepping stones, to fill up spaces in rock walls or on difficult corners. As a lawn it is slow but can be mowed once or twice a year, and should have little foot traffic. With below-freezing temperatures it will turn brown but sprout from roots and resume growth in spring. Use this medium-scale ground cover in full to part sun. Very drought tolerant when established but summer dormant under extremely dry conditions. USDA zone 9. Eastern Asia. Graminae/Poaceae. rev 7/2016
