Dianthus barbatus naturalized on a bank in Mt. Lebanon Park.




A deservedly popular ground cover often seen in Pittsburgh, noted for its silvery foliage and its carpet of pure white flowers in May and June.
Aesculus × carnea blooming in Oakmont.
Kale is a biennial. If you let some kale overwinter, it will give you cheery yellow mustard flowers in the spring, which will produce the seeds for another crop of kale.
Yes, old Pa Pitt did plant tulips right in front of this patch of daylilies just to prove that he has daylilies that bloom in tulip season.
The variety has no name, because it came from a batch of unnamed hybrid seedlings. But every year it reliably produces the earliest daylily flowers Father Pitt knows of, and every year he takes its picture, with a tulip in the frame if possible.
In Bird Park, Mount Lebanon.
