Nic operation and an excellent supplier of native plants for the region. Work with some of the better landscapers around MD. Note they no longer work with aquatics tho.

This place is amazing the owner mr. Wicklein is great too and he is reasonable too.

Wicklein's has quality aquatic plants for your pond or water garden. They no longer have retail walk-in sales, but you can order and pay online and have your order delivered or call and ask for a pickup if you are local. There are few places locally in north & central MD for QUALITY plants and this place is it. I am a satisfied customer who has returned for service anytime I need plants.
Try them out. I don't think you will be disappointed!
