Seed Exchange

Seed Exchange

I know it seems too early to be thinking seeds. Many of my plants are just starting to bloom. I just wanted to remind those who are interested that the seed exchange is going to take place ate the October meeting before the main program. Let a few of your garden native plants go to seed and bring the seed to the seed exchange. More information will follow in newsletters to come. There is information on seed collection available on the cnpsslo website under the resources/growing natives tab (link). Marti Rutherford

A Commentary by John Nowak, Plant Sale co-Chairperson

The other day, while checking out at the grocery store, the cashier noticed my CNPS hat and asked me, “How do you become an environmentalist?” I thought for a moment and then I told him “I would start at home.” (more…)

Plant Associations and the Geology of the Morros

Plant Associations and the Geology of the Morros

This photograph, taken from Cerro San Luis, shows Bishop Peak, Cerro Romauldo, and in the misty distance, Hollister Peak. The hills on the extreme left margin of the picture are the serpentinite ridge that backs Cuesta College, and the hills of the extreme right right margin are the western portion of West Cuesta Ridge. One of the obvious visual features is the dark chaparral scrub of the peaks, and the brown of the late spring grasses (more…)

Froom Ranch Opinion, Neil Havlik

Submitted to SLO Tribune

At the San Luis Obispo city Planning Commission meeting of Jan. 24 regarding the proposed continuing care facility known as Villaggio at the Froom Ranch, several commissioners wondered aloud if the project was not “a good project in the wrong place.” This came after a presentation that showed the project seeks removal of several important environmental constraints that constitute a grant of special privilege to the project sponsors. What are these constraints? What do the project sponsors seek? And how are these removals “special privileges”? (more…)

Pigs Attack the Saltmarsh of Morro Bay… again

Pigs Attack the Saltmarsh of Morro Bay… again

Wild pigs are again active in Morro Bay, causing damage while rooting for the tuberous reeds in the brackish freshwater seep zones close to the high tide line. This time they are at Shark Inlet. We last saw them in 2015 on both sides of the South Bay Boulevard bridge, and neither of the locations appear to have recovered. (more…)

Wildflower Alert

From time to time, our chapter has talked about creating a Wildflower Alert.  Well, there is a healthy display of wildflowers this year along the new ridge trail in the Reservoir Canyon Open Space near San Luis Obispo.  From the parking lot (see map), walk along the road for 100 ft., through the fence opening on the right, and then over the new bridge at the falls.  Once across the bridge, bear right and start up the hill.  Pictured here below are some of the flowers seen the weekend of April 21st, 2018. Link: http://gis.slocity.org/Documents/TrailMaps/rescanyon_bowdenweb.pdf

Horticulture 101 – The Basics

As someone once said “ Let’s start from the beginning.” Horticulture defined: the science and art of growing fruits, vegetables, flowers and ornamental plants. Native California plants, more or less, fall under the flower and ornamental plant category, though some are eaten as fruits and vegetables. (more…)

Lyonothamnus floribundus ssp. aspleniifolius is a mouthful to say but there is nothing edible about this tree. Lyonothamnus is endemic to the Channel Islands of California, where it grows in the chaparral and oak woodlands of the rocky coastal canyons. (more…)

Invasive Species Ailanthus altissima

Tree-of-Heaven

Ailanthus altissima

Britton and Brown’s 1913 Illustrated flora of the northern states and Canada Public Domain: Wikipedia

Ailanthus altissima is in the Quassia family. It is native to China. It grows in disturbed areas including riparian areas and may tolerate extremely harsh conditions. It forms dense thickets that outcompete native vegetation and reduce wildlife habitat. The female trees produce fruit at several years of age. One tree can produce 325,000 seeds or MORE annually! However, it does not produce a consistent seed bank. Tree-of-heaven also reproduces vegetatively from creeping roots. New shoots can sprout up to 50 ft. away from the parent tree. It is present in many places in San Luis Obispo County, especially riparian areas. It is difficult to control. Tarping seedlings may work. Small trees can be weed wrenched. The whole plant has to go: stump and roots. Ideally a chemical application on a cut stump should consist of 20% Garlon 4 Ultra with 80% crop oil.
