Weather permitting marginal and bog plants are shipped mid March through September OUR MARGINAL AND BOG PLANTS ARE EITHER IN 2 INCH POTS OR BAREROOT Depending on the weather, marginal and bog plants are ready to ship in March. Keep in mind we are in zone 5 and our plants are just coming out of dormancy in the early spring. This means that the plants will not be a full or awake as they will be later in the season. The most important thing to remember is that the root system is healthy. Unless other wise stated the hardy marginal and bog plants will winter over in zone 5 however, keep in mind each pond has its own micro environment, so they may do fine in Zone 3 & 4. We have done our best to give you information on the description of the plant and how it will perform our information is based on growing the plant here in zone 5. If you have any questions be sure to give us a call and we will be happy to assist you.
