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.

Title: Plants for the Shade of a Pine Tree in Pittsburg
Answered by: Anne Van Nest

QUESTION:

I live in Pittsburgh, PA. My neighbor has a huge pine tree. Last year everything I planted on that side near the tree died. That part of the yard only gets morning sun, as the tree overshadows it. What can I plant on that side that will survive being near the tree? I love lots of color.

ANSWER:

The first place to go to find a list of potential plants is our Native Plant Database. Use the Combination Search feature instead of Recommended Species. This will provide a bigger selection with much more choice to narrow down. The volunteers and staff at the Wildflower Center who maintain the database have partners in different regions to help with these recommended species lists based on what is easy to access in local nurseries.
Under Combination Search, select the following categories: State – Pennsylvania, Habit – herb, Duration – all durations, and Light Requirement – part shade and shade. This will give you a very large list of potential plants. You will have to narrow down this search further by indicating search criteria specifics for your soil moisture (is it dry under the pine tree?), lifespan (if you just want perennials), blooming time, height, and bloom color.

Some potential plants to consider include:
Geranium carolinianum (Carolina geranium)
Geranium maculatum (spotted geranium)
Helianthus divaricatus (woodland sunflower)
Helianthus strumosus (paleleaf woodland sunflower)
Lysimachia ciliata (fringed loosestrife)
Monarda didyma (scarlet beebalm)
Monarda fistulosa (wild bergamot)
Oenothera biennis (common evening primrose)
Penstemon digitalis (Mississippi penstemon)
Phlox divaricata (wild blue phlox)
Rudbeckia hirta (black-eyed Susan)
Solidago nemoralis (gray goldenrod)
Symphyotrichum novae-angliae (New England aster)
