Okay, so they're not exactly weeds, but master gardeners we are not. Outside the Glendale Main Library, nearly 1,000 different plant varieties grow on four acres. This collection of rare and unusual flora focuses on native and adapted plants that can be used in xeriscape design, including 600 varieties of low-water-use plants. The shrubs, trees, cactuses and sprouts are sectioned into handy categories, such as Cacti of Mexico and South America, Agaves of North and Central America, Berry Walk, and Medicinal Garden. (Suggestion: Add a "smokables" section.) Next to each plant is a sign listing its number, common name and scientific name -- sometimes even a book title for further reference.
As well-organized as this garden may be, some of these plants are practically begging for further categorization. Such as? 007's favorite plant: goldeneye. Plant that most sounds like a recreational drug: euphorbia. Plant most likely to sign for $252 million: Texas ranger. You get the idea.
