Gardening is rarely a source of instant gratification, but there are plants that provide almost sudden impact. Many have colorful foliage, season-long flowers or heady fragrance. And they are just the thing to beef up a new garden or to add an exotic touch to even the most established planting. “Adventurous Annuals” is a slide lecture detailing dramatic, fast growing annuals with almost architectural splendor. It covers everything from self-sowing annuals to easy-to-overwinter tropical plants and includes ideas for using these same plants for maximum effect in the garden, in beds or in containers.
