Many Idaho gardeners secretly wish for a touch of lush tropics or dense forest in some section of their yard. With all the talk of climate appropriate plantings, such desires are considered traitorous by some. But even people who are not intimidated into xeriscaping, can only do so much with microclimates and irrigation to moderate Idaho’s high desert weather. Moisture loving perennials perish. Annuals often stay puny. No wonder animal skulls are used as yard decor!
