Little League

P80217+K1There are so many big trees in the Santa Cruz Mountains that keep most of us looking up. It is easy to miss much of the understory plants that grow on the forest floor.

While getting the pictures for the ‘Six on Saturday’ article posted earlier, I happened to notice these few small pale flowers that contrasted more with their own dark green foliage than they would have if they were more brightly colored. Perhaps that is a technique to get the attention of pollinators. It certainly got my attention.P80217+K2.JPGThe flowers were not completely white. They were very pale hues of pink. The wood sorrel in the last picture was slightly more pinkish than the unidentified cruciferous (of the family Cruciferae) flowers of the first two pictures. Pale flowers, particularly those that seem to be adorned with barely perceptible patterns, are typically those that use infrared and ultraviolet color to attract pollinators that can see such color. If that was their intention, they would not look so bland to the pollinators whom they prefer to attract.

Much of the surrounding dark green foliage is exotic (non-native) English ivy. It climbs some of the redwood trees and makes quite a mess of the forest. Native specie are too docile to compete with it. The two species in these pictures might have been more common years ago, before the English ivy invaded.

Neither of these specie are the sort that I would plant in my own garden. I do not even know what the first species is. The wood sorrel looks too much like related oxalis. Although several specie of oxalis are popular in home gardens, I still think of them as invasive weeds. Yet, in their natural environment, they are too happy and pretty to not be appealing.P80217+K3

Poppies

P71213+K1Not just any poppies; California poppies, the state flower of California.

So why the picture of an old cinder block wall on the edge of an unkempt and weathered parking lot behind the old County Bank Building? Well, right there in the middle of the picture, where the lowest course of block meets the edge of the pavement are a few weeds, and some of these weeds are poppies showing how resilient they can be.

California poppies are opportunistic. They grow fast and bloom when they can. For most, that means that they bloom as the weather starts to warm up at the end of winter. For others in irrigated gardens, they can bloom in phases through summer. Some do their thing quickly as soon as they get a bit of moisture from the first autumn rains or even dew. They know what time of year it is, and that the weather will not likely get hot enough to cook them; so they bloom and throw their seed for another generation in a few more months, or maybe many months from now. They adapt. That is how they live on the edges of forests of the Santa Cruz Mountain, to interior valley chaparral, to the Mojave Desert. They are a remarkable specie.

Remember the poppies in the Wizard of Oz? There are several theories about what those poppies represent, and why the put Dorothy, the Cowardly Lion and Toto to sleep without affecting Scarecrow and TinMan. Duh, Scarecrow and TinMan do not breath. They can not inhale the narcotic produced by the poppies. Even if they did, they lack the physiology to be susceptible to opiates.

There is a significance to poppies blooming today, the same day I wrote about the gingko, on December 13; but this ain’t Oz.P71213+K2

Fire! . . . Again

P71018“It’s not nice to fool Mother Nature.” That old margarine commercial was lame back in the 1970s, but the quote is so true. Inadvertent interference with the natural process of wildfires has unfortunately increased the combustibility of the flora of forests and wildlands throughout California. No one really meant to interfere with the process. It is just what happens when we need to protect our homes and properties from fire.

The longer the vegetation is deprived of fire, the more overgrown and combustible it becomes. If deprived of fire long enough, many plants start to succumb to insect infestation and disease, and they become more combustible as they deteriorate and die. To make matters worse, so many of the exotic (non-native) plants that have been introduced into California are just as combustible, and some are even more combustible than native flora!

Combustibility is certainly no accident on their part. It is part of their ecology. Very few woody plants that are native to California even try to survive fire. The two specie of redwoods protect themselves with thick noncombustible bark so that they can recover from fire, even if much of the foliage gets burned away. Desert fan palms also recover after fire, after fueling it with their very combustible old fronds in order to incinerate competing specie. They are experts on this sort of ecology!

Most plants specie are neither so determine to survive fire, nor so creative in exploiting it as the desert fan palm is. They just live and die with it, only to regenerate and start the process all over again. Many release their seed as they burn. Some pines protect their seed within thick cones that open to disperse seed afterward. Seed of some specie need to be scarified by heat to germinate only after fire. Everyone want to be the first to exploit new real estate freshly cleared by fire, and they are always working on techniques to give them an advantage.

The problem with these processes is that they are not compatible with our lifestyles. As several big wildfires continue to burn throughout Southern California, another fire started early this morning just east of the Sepulveda Pass of the San Diego Freeway in Bel Air.
