Creeping Water Primrose

Creeping Water Primrose (Ludwigia peploides ssp. glabrescens). At Celery Bog Park, the northernmost wet area, just south of Cumberland Ave.  With months of dry weather the water level is receding and this Ludwigia is spreading over the area that is normally under water. The cylindrical cage in the background is the drain for the whole Celery Bog Park wetland system.  No outflow from this drain now though as the water level is too low.

Runners grow horizontally as the plant spreads and colonizes the newly exposed bare soil.
