The PHCA has been encouraging people to swap seeds and plants, so it’s nice to see this cool event.  Bring potted plants in containers with soil.   All plants must be identified; and no invasive species.  This is also a potluck event, so bring a dish to participate.  Donation of one plant suitable for the park is requested from each participant.  For more information, call 412.321.2852 or visit the Troy Hill blog.
