19 June 2022
Wildflowers bloom in two spurts in southwestern Pennsylvania: Woodland wildflowers in April before leaf out, “field” flowers in July-August after the solstice.
May and June are practically flowerless except for a few non-natives blooming in Schenley Park last week. Some are invasive. They thrive because deer don’t eat them.
- Chicory (Cichorium intybus)
- Greater celandine (Chelidonium majus), invasive
- Canada thistle (Cirsium arvense), invasive
- Goutweed a.k.a. bishop-weed (Aegopodium podagraria), invasive

The fly on the chicory is one of many species of hoverflies.
