An ornamental evening primrose

This is planted in Tapawingo Park in West Lafayette, Oenothera macrocarpa. Picture taken May 29, 2010. Oenothera macrocarpa has not been found in the wild in Indiana, but it is native to regions west of the state. Other native plants that are used in the landscaping here are switchgrass (Panicum virgatum) and fragrant sumac (Rhus aromatica). You can find them planted a few steps away.

A row of catalpa trees

Flowers cover these catalpa trees as if it were a blanket of snow. Cottonwood seeds fill the air. This row of catalpa trees has been here a long time. Where are the snows of yesteryear?

Golden Alexander

Zizia aurea, Golden Alexander, at Celery Bog Park. This is in an open area near the entrance drive, there seems to be a lot of this plant in this area. Golden Alexander is a native wildflower but doesn't seem too common elsewhere, I will guess that it was spread here intentionally by the park as part of a restoration project.

This Golden Alexander is in the butterfly garden adjacent to the Celery Bog Nature Center and is certainly intentionally planted here.

Pictures taken May 2, 2010.

Squawroot (Conopholis americana), at Happy Hollow Park in West Lafayette. There seems to be a lot of this plant in this place. Squawroot is parasitic on the roots of oak trees and so doesn't have the green color of chlorophyll that most plants have. Picture taken May 2, 2010.

Notice the male oak flowers scattered on the ground, fallen from the tree.

Fire pink

This fire pink (Silene virginica) is on a wooded slope in Happy Hollow Park in West Lafayette. Picture taken May 2, 2010.
