Don’t Fight the Site


By Paul James

Heavy clay. Sandy or rocky soil. Wet areas. Dense shade. Those are but a few of the challenges gardeners face, and dealing with them can be frustrating, back-breaking, and expensive. But none are insurmountable if, rather than try to change the conditions, you make the most of what you’ve got.

So here are several suggestions for plants that will adapt to difficult or problem sites. The lists are by no means complete, but they’ll get you off to a good start.

Plants for Clay Soil

Funny thing about clay soil. On the one hand it tends to hold moisture and can cause the roots of many plants to rot. But on the other hand it’s nutrient rich. These plants like the combination.

Arborvitae

Elderberry

Salvia

Aster

Forsythia

Sedum

Bald Cypress

Fringe Tree

Serviceberry

Bearded Iris

Gingko

Shumard Oak

Bee Balm

Hosta

Smoke Tree

Butterfly Bush

Ninebark

Spirea

Chinese Elm

Quince

Sweetspire

Coneflowers

Redbud

Tupelo

Daylilies

River Birch

Viburnum

Dogwood

Rose of Sharon

Weigelia


Plants for Wet Soil

Some areas remain swampy or boggy pretty much all the time, whereas others dry out between waterings or following a soaking rain. These plants can handle both conditions so long as the soil doesn’t remain dry for long.

Astilbe

Pussy Willow

Atlantic White Cedar

River Birch

Bald Cypress

Serviceberry

Carolina Jessamine

Spiderwort

Chokeberry

Sweet Flag

Cinnamon Fern

Sweetspire

Clethra

Trumpet Vine

Lily of the Valley

Tupelo

Lobelia

Wax Myrtle

Northern Sea Oats

Willow

Painted Fern

Yaupon Holly


Plants for Sandy and Rocky Soil

Although these soil types tend to drain very quickly, it’s better to deep soak each time you water rather than water frequently but shallowly. They also tend to be nutrient poor, but again because they drain quickly it’s best to use a slow-release fertilizer such as Osmocote or any number of organic products.

Baptisia

Lavender

Black-Eyed Susan

Little Bluestem

Butterfly Weed

Ninebark

Catmint

Penstemon

Coneflower Gaillardia

Phlox

Coreopsis 

Russian Sage

Creeping Jenny

Sage

Creeping Juniper

Sedum

Hellebore

Sumac

Joe Pye Weed

Plants for Dense Shade

A couple of hours of morning sun is okay, but these plants thrive in deep shade such as what you’d find beneath mature trees or under eaves.

Anemone

Liriope

Astilbe

Mondo Grass

Begonia

Pachysandra

Caladiums

Sea Oats

Carex

Solomon’s Seal

Climbing Hydrangea

Sweetspire

Ferns

Tricyrtis

Hellebore

Yews

Hosta



Don’t get me wrong, folks. If you’d rather spend big bucks on excavating lousy soil and backfilling with topsoil and compost, or hiring a contractor to dig a pricey French drain, or paying an arborist to thin the canopy of mature trees to allow more light to reach the ground, be my guest. Just remember — you don’t have to fight the site.

Happy gardening, ya’ll.
