When we talk about weeds, we often use the definition of "a plant out of place". While that's a bit human-centric for some folks, it does provide an introduction for me to share some of my favorite plants-out-of-place photos.
Credit for this first one goes to my wife who, knowing my appreciation for both weeds and strawberries, snapped a photo of this common groundsel seedling in a clamshell of berries at the local supermarket.
Next, I ran across one of Lynn's photos of real weeds in artificial turf. (she actually

It really has gotten out of hand--Hairy Fleabane and Horseweed which are both Conyza weed species that have run rampant this year because of the extra rain. It's also because they have become resistant to glyphosate herbicide. The problem has shown up all over the US and other parts of the world. Gradually as resistance has grown and their resistant fairy seeds have floated wherever the winds go, the weed is having a field day everywhere in.../h3>
We have become aware that common purslane (Portulaca oleracea, Fig. 1) is an increasing problem in alfalfa fields, particularly during the months of July through September. A pest control advisor (PCA) was recently seeking advice on managing purslane in glyphosate-tolerant alfalfa fields this summer. He said that the purslane was getting raked up into the windrowed hay, and he was concerned that the moisture of the purslane would cause mold and hay discoloration or even spontaneous combustion of the hay once baled. He said that glyphosate was not effective at controlling the purslane, and he was considering applying carfentrazone (Shark) as an in-season, post-emergence herbicide. Let's dissect this situation.

The U.S. Bureau of Reclamation (BOR) is one of the agencies responsible for operating a facility that pumps water from the Sacramento-San Joaquin Delta into the California Aqueduct. The California Aqueduct pumps water for uses south of the facilities. This water is used for agriculture in the San Joaquin Valley valued at $33.4 billon in 2015 (CAC 2015), and for millions of other users in Californian homes and businesses.
Before that water can be pumped, debris, weeds and fish must be removed. This is done at the Tracy Fish Facility. A series of screens and diversions are used to remove the objects and capture the fish. The debris is mechanically removed from the river, and the fish are transported and released...
