Introduction to the Weeds
The likelihood of an impoverished Earth of weeds and remnant human societies is growing stronger every day now. Human population, climate change, toxic pollution, and dwindling resources needed by living beings are all reaching points of no return. In a few years now, it will be too late to prevent global catastrophe.
The ability of weeds to reach and thrive in damaged and inimical environments suggests that they may be the principal survivors of the impacts to nature by human overpopulation, pollution, and climate change. In this book, I attempt to answer two questions:
- Which weeds are present in Dewey-Humboldt (D-H) now or will arrive in the future? Answering this question requires that we can identify the weeds. Drawings and descriptions of the weeds take up most of the pages. The descriptions contain answers to the second question:
- Are the weeds of D-H valuable resources for wildlife and people? I reviewed the literature and added symbols for edible and medicinal weeds.
The inspiration for the book is a fascination with the intricate shapes and dynamic features of the weeds. I warn you that there is a danger that if you look closely at these creatures, you might never turn away.

One of our weeds:
Alkali Heliotrope (also known as Quail’s Delight).
Alkali Heliotrope (Quail’s Delight)
(Heliotropium curassavicum var. oculatum ).
Alkali Heliotrope’s tiny fragrant flowers delight bees and gnats. The uncoiling spike, a flower-studded fiddleneck, reveals little beauties pure white with yellow-green eyes that purple in sunlight. This bluish green perennial grows to about one foot, but mostly it forms flat patches of overlapping branches up to four feet wide. The plants are hairless, but lightly dusted with a white powder that easily rubs off.
A native of arid North America, Quail’s Delight can edge into a lawn or garden. Removal by pulling is a simple cure, but the plant has no thorns or burrs and you might wish to leave it on unused sites where it will protect your soil from wind and water erosion.
The plants colonize exposed alkaline or saline soils and the banks of streams and washes in arid western U. S. and Baja California. You will find similar varieties around the world. I’ve seen this one growing beside a canal in Tempe, Arizona, and a very similar variety beside limestone rocks near Fourteen Mile Creek in Oklahoma.
