Drought-Tolerant Plants

Plants that ask for water while they root, then fend for themselves. Chosen for gardens on sand, slope, or full baking sun, these are the tough, sun-loving plants that flower hardest in the heat and shrug off a dry August once established.

Ptelea trifoliata, hop tree, papery wafer-like winged seeds.
Hop Tree, Wafer Ash
Ptelea trifoliataHop Tree, Wafer Ash

Ptelea trifoliata, the hop tree or wafer ash, is a unique and underappreciated native, a small, bushy deciduous tree of eastern and central North America. Highly adaptable, the plant takes dry, rocky ground as readily as moist, well-drained sites, which makes the hop tree a fine choice for naturalized landscapes, pollinator gardens, and woodland edges.

Phyllis Fancy Sage
Salvia ‘Phyllis Fancy’Phyllis Fancy Sage

Salvia 'Phyllis Fancy' is a vigorous, large hybrid sage with a good pedigree, found as a chance seedling at the University of California, Santa Cruz Arboretum and named for a longtime volunteer there. The parentage is thought to involve Salvia leucantha, the Mexican bush sage, and possibly Salvia chiapensis, though the cross has never been confirmed.

Salvia microphylla 'Deltoid' soft salmon-coral flowers
Littleleaf Sage
Salvia microphylla 'Deltoid'Littleleaf Sage

Salvia microphylla 'Deltoid' is a shrubby form of the littleleaf or baby sage grown for warm salmon-coral flowers and neat, triangular, deltoid leaves. The small tubular blooms open over a long season and read as a soft coral against the fine, glossy foliage, a gentler tone than the hot scarlet of many littleleaf sages.

Salvia microphylla 'Hot Lips' bicolor red-and-white flowers
Littleleaf Sage
Salvia microphylla 'Hot Lips'Littleleaf Sage

Salvia microphylla 'Hot Lips' is the famous temperature-shifting bicolor of the littleleaf sages, and the trick is worth the fame. In the cool of spring the flowers may open pure white or pure red, but as summer heat builds they turn strikingly two-tone, white below with a bold red lip, so that a single plant can carry white, red, and red-and-white flowers all at once. The show runs from late spring until frost.

Tilia americana, American basswood, pale yellow fragrant flower clusters in summer.
American Basswood
Tilia americanaAmerican Basswood

American basswood is one of the great shade and honey trees of eastern North America, a fast, stately deciduous tree with large, heart-shaped, softly toothed leaves and a broad, rounded, generous crown. Tilia americana has been cherished by Indigenous peoples, European settlers, and naturalists alike, and goes by a string of names: linden, bee tree, and lime, though the tree is no relation to the citrus lime. In late spring and early summer, hanging clusters of pale yellow, sweetly fragrant flowers open and hum with bees.
