As you contemplate digging into perennial gardening, approach it from the standpoint of solving landscape problems. There's a perennial that will thrive in every growing solution. If you have a slope too steep for mowing, you can trade turf for perennial groundcover. Near downspouts and low spots in your yard where water gathers after downpours, moisture-loving perennials can transform an eyesore into a beauty spot. Mike Jensen Where lower rainfall dictates water restrictions, tap into the world of xeriscape plants, which grow and flower profusely with little moisture. Natural deposits of acidic soil can support lovely perennials that will make you grateful for the locally low pH. Stop fighting to grow grass beneath shade trees—plant shade-loving perennials instead! You can even find perennials that serve as lawn stand-ins—tidy, ground-hugging plants that withstand foot traffic and stay green year-round. In municipalities where surface runoff adds charges to your water bill, incorporating a rain garden filled with moisture-loving perennials will dissipate roof, driveway, or patio runoff into the soil and can reduce your water fees. Use this list of perennials adapted to various growing conditions to draft solutions to your landscaping problems. Richard Hirneisen Perennials for Wet Soils If your garden bed is down in a ditch or next to the downspout, you're probably stuck with soggy soil that drowns plants. There are plenty of varieties that can withstand (and even thrive) in that much moisture.

Flowers like astilbe, bleeding heart, and phlox can also do well in shade and make excellent planting partners for hardy hosta. Astilbe: Long-lasting flower stalks in summer Barrenwort: Red, pink, white, purple, or bicolor blooms in early- to mid-spring Foamflower: White or light pink flowers in mid-spring Hardy Begonia: Heart-shape foliage; pink flowers in late summer Hosta: Grown for foliage; many cultivars See our favorites here.

Rob Cardillo Photography Perennials for Alkaline Soils In certain areas of the country, soil's acidic balance can be off-kilter, resulting in what we call alkaline soil. Alkaline soil doesn't let much moisture in and has a weak soil structure that just can't keep certain plants happy. You can still work with this type of soil without investing in pounds of soil amendments—just look for these plants. Anemone: Late-Summer or fall flowers Coralbells: Many cultivars with colorful foliage Creeping Baby's Breath: White flowers in summer Geranium: Spring or summer flowers depending on species; foliage of many turns red in fall Pincushion Flower: Blue flowers on wiry stems summer to fall Dianthus or Pinks: White, pink, or red flowers in spring and summer; evergreen foliage in some areas Baptisia. Susan Gilmore Perennials for Dry Soils Typically, dry soils contain a lot of sand, which doesn't hold moisture very well. You need especially hardy plants that don't need consistent or large amounts of water. Try some of these.

Mallow: Shrublike with white, pink, or purple-pink flowers all summer Marty Baldwin Perennials for Acidic Soils Just like alkaline soils, acidic soil is a result of a lack of balance of nutrients in the soil. Instead of having too little acidic content, acidic soil has too much, which can be a result of organic matter, excessive rainfall, or too much fertilizer. But, you can still grow gorgeous flowers in acidic soil. Bear's Breeches: Tall flower spikes in late spring to early summer and texture-rich foliage Cinnamon Fern: Reddish-brown fronds in center of plant Fringed Bleeding Heart: Finely cut foliage; flowers in summer Liatris or Gayfeather: Purple or white flower spikes in early- to midsummer Bergenia: Shiny evergreen foliage with pink blooms in early spring Japanese Iris: Showy flowers in late spring or summer Hellebore or Lenten Rose: Flowers in late summer Yarrow. Tom McWilliam Perennials for Clay Soils You know if you have clay soil—you come out of landscaping projects with sticky boots and a sore back from shoveling the dense earth.
