For lovers of the prickly vegetable, the presence of groves of wild artichokes, as we have in the Valley of the Moon, might seem like an indication of paradise. In addition to being delicious, artichoke flowers are beautiful, fragrant, and attract bees.
However, the wild cynara carduncula is a fearsome invasive plant.
According to the California Invasive Plant Council, the thistle was probably imported from Europe in the early 19th century as a food plant. It becomes invasive when it escapes cultivation and begins to reproduce from seed. Darwin found it growing in the Argentine pampas in 1889 in an area of “hundreds of square miles.”
At its worst, the “edible thistle” forms thickets that are impenetrable by humans or animals and that shade out native plants. As they develop tap roots eight feet deep and produce seed banks that endure for five years, they are very difficult to control.

Very early spring 2018, the little calendula are filling many of the open spaces in Sonoma Valley. Some folks think it’s a weed, others love it.
Is it a weed?
“Calendula (probably arvensis, but there is a larger flowered officianalis) is listed on Cal Flora as non-native to our area but not invasive. So it depends on your definition of a weed: any non-native, or the ones that most upset biodiversity? I don’t mind them; they’re pretty and have some medicinal uses. Since they tend to grow in disturbed and/or agricultural areas, no one knows for certain what grew there in the first place, so planting something else with the goal of restoration would involve some guesswork.” Hannah Aclufi via Facebook
According to Wikipedia:
A weed is a plant considered undesirable in a particular situation, “a plant in the wrong place”.
Examples commonly are plants unwanted in human-controlled settings, such as farm fields, gardens, lawns, and parks. Taxonomically, the term “weed” has no botanical significance, because a plant that is a weed in one context is not a weed when growing in a situation where it is in fact wanted, and where one species of plant is a valuable crop plant, another species in the same genus might be a serious weed, such as a wild bramble growing among cultivated loganberries. In the same way, volunteer crops (plants) are regarded as weeds in a subsequent crop.
Many plants that people widely regard as weeds also are intentionally grown in gardens and other cultivated settings, in which case they are sometimes called beneficial weeds.
These little plants tend to inhabit waste spaces, roadsides, and untended open fields. They will grow in gardens, but are easily removed and are not aggressively spreading, like oxalis or dandelions.
So there can be a differing of opinion.
The term weed also is applied to any plant that grows or reproduces aggressively, or is invasive outside its native habitat. More broadly “weed” occasionally is applied pejoratively to species outside the plant kingdom, species that can survive in diverse environments and reproduce quickly; in this sense it has even been applied to humans.
So, let’s not get up on our high horses when deciding what is a weed or what isn’t. Humans are a weed species, but there are some benefits to our existence!
Calendula have medicinal uses as a remedy for skin problems as well as an anti-inflammatory.
And, on a taxinomical note:
“There is a lot of magic in the naming of things. It is my contention that the more we know about nature’s secrets, the more we can enjoy it. Simply being able to call the elements of nature by their proper names helps us to experience them and allows their beauty to unfold…” Obi Kaufmann, The California Field Atlas.
“I find the Latin names for the plants as beautiful as the plants themselves … “ Wyethia Angustifolia (Hannah Aclufi) https://viridiplantae.com/about/
Just south of the Sonoma Mission Inn, on the west side of Highway 12, Sierra Drive intersects.
At that corner stands one of our landmark oak trees. The tree is in front of the building that now houses Ross Drulis Cusenberry Architects. The building was built in 1966 for Sierra National Bank. It seems that the street, originally known as Meincke Road (more on that later), was renamed for the bank. The street also has the distinction of being on the former NWPRR right-of-way (the tracks were removed in 1942).
Our tree is a Valley Oak, Quercus lobata. According to the California Native Plant Society (http://calscape.org/), the Valley Oak ranges over the interior valleys of the State, and needs to be near a source of water (Lily Creek*, which flows down Arroyo Road, tunnels under the highway very near the tree.) It can grow to 100’ in height and live for as many as 500 years. The tree in question, which has three trunks, certainly could be 100 years old. We have a photograph of the tree (and building) from 1973, which shows it to be in pretty poor shape. In 2018 it appears to be much healthier.
*Thanks to Greg Larson for the creek name.

Oaks are never more beautiful than in winter.
