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: Container plants for terrace in New York City
Answered by: Barbara Medford

QUESTION:

What flowering plants would you recommend that will grow well on a 16th floor terrace ,with all day sun in NYC?

ANSWER:

As we hope you already know, the Lady Bird Johnson Wildflower Center is committed to the use and propagation of plants native not only to North America but to the area in which they are being grown. We will select from our Native Plant Database herbaceous blooming plants that do well in full sun and are native to New York. First, we suggest you read our How-To Article, Container Gardens with Native Plants. Next, we will go to our Recommended Species, click on New York on the map, NARROW YOUR SEARCH and select on "herbs" (herbaceous flowering plants) for habit and "sun" for Light Requirements. We consider "sun" to be 6 hours or more of sun a day, "part shade" 2 to 6 hours of sun, and "shade" Less than 2 hours of sun. We will only be choosing a few examples, and you can go back, using the same method and select others that better suit your purposes. You can use the Narrow Your Search option to select for bloom times, colors, duration (perennial or annual) and even choose different habits, like "shrub" or "vine." Follow the plant links to the webpage on the individual plant and find out the expected size, water requirements, etc.

Achillea millefolium (common yarrow) - perennial, 1 to 3 ft. tall, blooms white, pink April to September

Campanula rotundifolia (bluebell bellflower) - perennial, 4 to 15 inches tall, blooms blue, purple June to September, sun to shade

Conoclinium coelestinum (blue mistflower) - perennial, 1 to 3 ft. tall, blooms blue, purple July through November, sun, part shade
