Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Topic: Shade Tolerant, Herbs/Forbs
Title: Balancing bloom in beds in Kents Store VA
Answered by: Barbara Medford

QUESTION:

Our beds along a walkway in rural Central VA have replanted themselves - oenethera speciosa and dwarf yarrow have abandoned the north bed and are flourishing in the south bed. Sedums, lavender and candytuft seem to like both sides. The overall results are very unbalanced. We have poor clay soil, alkaline, some drought in the summer. What can we do to get some taller native flowers to grow on the north side of our walkway?

ANSWER:

We don't seem to have enough information to answer your question, so we'll do some speculating. You have to figure out what is different between the two beds. Does one have more shade than the other, or less opportunity for irrigation or does water sometimes stand on one bed and not the other? If we understand you correctly, all the plants you named started out in both beds. In the Spring, 2 plants, the oenethera and the yarrow, didn't come up in the north bed. It's not that the plants in the north bed migrated, they just failed to re-emerge in the north bed when Spring came.

Good in the south bed but not in the north bed:

Oenothera speciosa (pinkladies) - needs full sun (6 or more hours of sun a day) and moist soil, native to your area

Achillea millefolium (common yarrow) - sun or part shade, can withstand dry soil, prefers moist, native to your area

Good in both beds:

Sedum ternatum (woodland stonecrop) - sun or part shade, moist soil, native to your area

Iberis sempervirens (Candytuft) - full sun, native to Africa, Asia, Europe

Lavender - native to the Meditteranean area, likes dry, sunny area

It looks to us like there was/is more shade than the plants that failed to come up in the north bed could withstand. Since the Lady Bird Johnson Wildflower will only recommend plants native not only to North America but to the area in which the plants are being grown, we will find some native blooming plants that are okay with part shade (2 to 6 hours of sun a day) or shade (2 hours or less of sun a day.) You can follow each native plant link to its database page to learn about its culture, light requirements, colors and so forth.  If both beds have full sun, you will have to examine other factors that might be different, going back to Recommended Species, clicking on Virginia on the map, and then selecting herbs (herbaceous blooming plants), perennial in Lifespan, sun in Light Requirements, and then Narrow Your Search. If you wish to change the Light Requirements or put in the soil moisture, that will narrow your choice down even more. 

Herbaceous Blooming Plants for part shade or shade in Virginia:

Aquilegia canadensis (red columbine)

Asclepias tuberosa (butterfly milkweed)

Caltha palustris (yellow marsh marigold)

Campanula rotundifolia (bluebell bellflower)

Conoclinium coelestinum (blue mistflower)

Coreopsis lanceolata (lanceleaf tickseed)

Gentiana clausa (bottle gentian)

Iris versicolor (harlequin blueflag)

Lobelia cardinalis (cardinalflower)
