NOTE: A graduate student at CSU Fresno is looking to describe the geographic distribution of alkaliweed in California. Please see the end of the article for a link to a QUICK survey describing where YOU have encountered this species.
Growers (mainly pistachios) and crop consultants in the southern and western parts of the San Joaquin Valley have recently reported the spread of alkaliweed from low-lying saline or alkaline soils (including seasonal wetlands and floodplains) into irrigation ditches, orchards, and some agricultural fields.

Italian ryegrass (Lolium multiflorum) is an annual grass that can sometimes behave as a biennial or short-lived perennial in California. The species is upright in habit (to about 3 feet in height); seeds germinate in the late fall and the plants grow vigorously through the winter and early spring. Ryegrass can be identified by its dark green, glossy and hairless leaves that are rolled in the bud. Auricles are well-developed and the ligules are long and membranous. Once flowering occurs, ryegrass is easily distinguishable by alternating spikelets that run along the length of the main flowering stem (April through September). Additional photos can be found at the end of this post; more details regarding Italian ryegrass...

You just KNOW that some plants are considered weeds. Their common names give them away. They sound awful. Giant hogweed (Heracleum mantegazzianum). Ripgut brome (Bromus diandrus). Devil's claw (Proboscidea lutea). Smellmelon (Cucumis melo). Itchgrass (Rottboellia cochinchinensis). Dog-strangling vine (Cyanthum rossicum).
Others...well, others seem more benign. Even sweet. For Valentine's day I present to you nine weedy plants with lovely names. Enjoy...
1. Tree-of-Heaven (Ailanthus altissima). How celestial (Sigh...). How divine (Sigh...). How invasive (sigh...wait, what?). Tree-of-heaven is a deciduous tree, native...
