Among the most architectural plants, agaves feature bold succulent leaves that set the tone for wherever they're planted. They're incredibly heat- and drought-tolerant and most are long-lived. Many varieties bear sharp spines along leave margins and at the leaf tip, which adds to their dramatic presentation. The bluish-green rosettes naturally spread by producing offsets at the base of the plant. It is an excellent choice for sunny, hot, dry areas, especially desert regions, with good drainage.

Penstemon, Beardtongue, Deer, Deer-Resistant, Landscape

This North American native plant has a home in nearly every garden with flowers that hummingbirds love. Long blooming with brilliantly colored, tubular flowers, penstemons -- ironically -- have been a staple in European gardens for decades.There are many different penstemon types. The leaves are lance-shape or oval, sometimes purple-red as in 'Husker Red'. Some Western species need outstanding drainage to dry conditions and won't thrive during wet weather. However, many, such as 'Husker Red', thrive in a wide variety of conditions. Just be sure to provide excellent drainage. Mulch in areas where a type is marginally hardy.
