Please join us for a relaxed and interesting evening.

Conservation Report: November/December 2014

A colony of Stinkwort (Dittrichia graveolens) has recently been discovered in Arroyo Trabuco at the edge of Ladera Ranch. Stinkwort is one of California's most serious invasive plant threats, especially in the Bay Area and northern Central Valley. This was the first time it had been discovered in OC. It was found by OC wildflower expert Bob Allen. The population covers about 1.7 acres along a narrow gravel roadway and adjacent footpath in an area just north of the Crown Valley Parkway bridge over Trabuco Creek.

Bob immediately reported the infestation to OCCNPS and within a few days chapter members had mapped the infestation and begun steps to insure its immediate removal. 

OCCNPS’ Invasive Plant Subcommittee, led by Dr. Jutta Burger, Ron Vanderhoff and Celia Kutcher, with Bob’s assistance, communicated the significance and urgency of the infestation to Jennifer Naegele, Chief Restoration Ecologist at OC Parks. Because the plants were already dispersing seed, if OC Parks was unable to act swiftly, our chapter offered to mobilize its own volunteers. With our urging, Jennifer and OC Parks have organized resources to remove this year's infestation. Ongoing removal efforts, combined with several years of monitoring will be needed to ensure complete eradication. OCCNPS will continue to monitor the area. (Many thanks to Ron Vanderhoff for the information in this article.)


Native Gardener's Corner: November/December 2014

Native Gardener’s Corner-Member’s Tips, Tricks, and Techniques has been a regular newsletter feature since the September/October 2009 issue, offering chapter members and local experts a chance to briefly share information on many things related to gardening with natives. Now that planting season is here, this seemed a good opportunity to share some of the excellent information from past columns.
Here are excerpts from November/December 2009: “Which native plant do you find to be the most successfully grown in a wide variety of landscape situations and “looks good” for much of the year?”

Laura Camp: Arctostaphylos 'Howard McMinn' - Lovely glossy leaves, absolutely gorgeous flowers, hummingbird plant, with terrific bark. It can be pruned every which way, works in clay soil, can take full sun (to quite a bit of shade), and although it can take some peripheral water, it is of course drought tolerant.  Manzanitas are great, great plants, and this hybrid/cultivar is a best seller and sometimes can be found at Home Depot for good reason.

Sarah Jayne: Rhus integrifolia, Lemonadeberry. It's trainable and tractable, produces flowers in late winter and red berries most the summer. Can be ungainly in shape, but can be pruned to fit any situation. Seeds sprout all over, but they are easily removed (when young) To me, it is one of the great, reliable, locally appropriate garden backbone plants.
