Pontederia
cordata PICKERELWEED |
| The pickerelweed is an aquatic
herb found in many shallow (rarely more than 3 foot deep) depressional
marshes. Only 10cm of the plant itself are emergent, although the
plants create large mats over the water. Mostly blue but occasionally
white flowers are arranged into conical spikes that bloom from July
to August. Above water the leaves are 18cm and heart-shaped; below
water they are 4.5cm ribbons. |
