Gardeners and garden designers are having a love affair with agaves. It's easy to see why—they're low maintenance, drought-tolerant, and strikingly sculptural, with an astounding range of form and color. Many species are strikingly variegated, and some have contrasting ornamental spines on the edges of their leaves. Fabulous for container gardening or in-the-ground culture, they combine versatility with easy growability. In Agaves, plant expert Greg Starr profiles 75 species, with additional cultivars and hybrids, best suited to gardens and landscapes. Each plant entry includes a detailed description of the plant, along with its cultural requirements, including hardiness, sun exposure, water needs, soil requirements, and methods of propagation. Agaves can change dramatically as they age and this comprehensive guide includes photos showing each species from youth to maturity—a valuable feature unique to this book.
