Dudleya: Succulent Diversity in Our Own Backyard John Martinez and Nils Schirmacher Our local mountains are home to a plentiful and varied assortment of Dudleya. Each of the 11 species and 6 subspecies inhabiting the Santa Monica and San Bernardino Mountains can be found within an hour s drive from central Los Angeles. For the past two years, John Martinez and Nils Schirrmacher have photographed these succulents in habitat, trekking slopes and canyons to uncover our native treasures. Their introduction to the breadth of local Dudleya will feature their photos and impart lessons learned in the field. John currently lives in Moorpark with his wife Linda and is a retired Los Angeles Fire Department Battalion Chief. He is a member of the San Fernando Valley Bromeliad Society, the Los Angeles CSS, San Gabriel Valley CSS, a founding member of the newly formed Conejo CSS, and a past volunteer at the Huntington Botanical Garden. John has a deep fondness for nature and has been growing xeric plants most of his adult life. Over the past 6 years he has shared a co-op succulent growing compound in Somis with three experienced growers of cactus, succulents, and other exotics. Aside from maintaining his plant collection, John s time is divided between gardening, golf, photography, occasional fly fishing, and grandchildren. As a native of Southern California John attended California State University of Northridge, where he received a Bachelor s Degree in Art. The article on this month s presentation is continued on the next page. 2
Nils Schirrmacher has been collecting succulents since 1999, the year he joined the CSSA. In 2005, he became a member of the Los Angeles Cactus and Succulent Society and currently serves as club historian. From his Los Angeles apartment, he s building a collection of seedgrown plants that includes members of the Aizoaceae, or mesembs. This pursuit lead to his joining the Mesemb Study Group in 2014. Nils holds a Master's Degree in Art from UC Irvine and has had several gallery exhibitions of his work. By day, he works as an art handler.

San Gabriel Valley Cactus and Succulent Society Cacti of the Month January 2017 - Mammillaria Clusters Article and photos by Tom Glavich Mammillaria is one of the larger genera in the Cactus family, and one of the most variable, with some members remaining as solitary columns for their entire lives, some remaining as fingernail size solitary globulars, some clumped and heavily spined with hooks, straight sharp spines or feathery soft spines. Although most Mammillaria are native to Mexico, some species in the genus can be found from Columbia to Kansas and California. With this wide distribution the cultivation requirements obviously vary considerably. The species from the tropics and warmer areas are rarely tolerant of cold and damp. Those from the drier desert regions are also intolerant of continued damp but can take considerable cold. With these restrictions aside, most Mammillaria are easy to grow. The secrets to good growth are a continued supply of fertilizer during the growing season, strong light, and maintenance of a clean and insect-free growing environment. The white and densely spined species want full sun, and do best on a table unprotected (except from prolonged heavy rain) all year long. The appearance of white mealy bug egg cases (Mammillaria s worst enemy) on the tips of the spines or the appearance of ants means that mealy bugs are sucking the sap and life of the plant. Immediate treatment is required with a thorough washing and spraying with an insecticide. Propagation of Mammillaria clusters is easy. Cuttings can be taken at any time during the growing season (April to early November), left to dry for a few days and replanted in a clean potting mix (pure pumice is even better). Rooting is rapid with short white roots generally appearing after a couple of weeks. Mammillaria are one of the easiest species to grow from seed. The seeds are simply placed on top of a damp potting mix, covered with a light coating of gravel, placed in a plastic bag in bright light but out of direct sun and allowed to germinate. Germination usually occurs in a week or 10 days. The seedlings can stay in the plastic bag for several weeks until they get large enough to survive unprotected and should then be removed to a still shaded, but brighter and drier environment. Show quality plants can often be grown in just 4 or 5 years and entries can be ready for seedling classes in as little as 6 months. Best results are obtained when the seeds are started in late March to late May. 4
Clumping Mammillaria Mammillaria baumii is a densely spined species with wonderful large yellow flowers. It is easy to grow, and makes an impressive specimen in a modest size pot. It comes from Tamaulipas and Mexico. Mammillaria duwei, is from central Mexico. At first it is slow to pup, but persistence and patience pays off. Mammillaria elongata, one of the first cacti that everyone grows, is easy and extraordinarily tolerant of abuse. It has the odd characteristic of being very popular and also unfairly neglected since advanced growers ignore this easy grower even though there are a variety of forms and colors, many of which can make a spectacular plant. Mammillaria geminispina, is a variable species with some varieties having short white spines while others have long flexible centrals. Mammillaria herrerae is a spectacular small white species with very dense interlacing spines. It comes from Queretaro Mexico. Mammillaria lenta, from Coahuila, forms mounds of offwhite to white. Slower growing than the somewhat similar M. plumosa, described below, it is often a show winner. Mammillaria crucigera (see above photo) produces clumps by splitting dichotomously (each head splitting into two). The body ranges from green to almost brown to almost purple. This species is a slow grower. Mammillaria luethyi from Coahuila, and discovered in 1997, is now available in cultivation. It is a breath-taking miniature with very short white spines on a dark green body. Mammillaria plumosa is a relatively quick grower forming mounds of white heads. The heads are covered with white feathery spines which must be kept dry if the color is to be maintained. Mammillaria standleyi can be found as either a single or clumping species. In cultivation, clumping forms are much more common. It is a rapid grower. Editor s note: Lynee Levin-Guzman displayed a Dioscorea elephantipes at the SGVCSS Winter Show and Sale. The photo was in the December Communique, but she was not given credit. 5

San Gabriel Valley Cactus and Succulent Society Succulent of the Month January 2017 - Agaves Article by Tom Glavich The Agave family, like the Cactaceae family, is entirely new world in origin, although many members have been naturalized around the world. Agaves are native to Southern North America, Mexico, Central America, Northern South America and the West Indies. There are dwarf forms just a few inches across, but most species are larger, spanning the range of 8 inches to 10 feet. Although many members of this genus grow very large with age, they are particularly good looking as seedlings and can be kept small for many years in pots. All of the species described below are easily grown in Southern California. They can remain unprotected in pots or the ground year-round. They thrive with regular feeding with any general-purpose fertilizer. They appear best when they are cleaned regularly with debris removed from the leaves and dead leaves removed to prevent insects from making homes. Many offset freely and these offsets can be removed and repotted, giving a steady supply of small plants. Some growers keep the offsets and dispose of the mother plant, thereby keeping size, health and condition under control. Some Agaves will get sunken spots on the leaves when grown in pots. This blemish takes several years to heal and can be avoided by pruning the roots back to about 1/3 of their length and then repotting. All Agaves are easily grown from seed - the difficulty for most species is in getting seed. Increasing interest in the genus has made this easier with many species now available on some of the better seed lists. There still are many species and cultivars that are not available. Seed should be started when the weather turns warm and night temperatures are consistently above 50 F. This allows constant growth through the first summer, and prevents seedling loss. There is increasing interest in variegated agaves as well as monstrose and crested agaves. All of these are welcome at this month s meeting.
