Hi minionsweb! The clover you will get is already planted in a 4 inch pot of aquatic soil. This plant needs to be submerged under at least a couple of inches of water for it to perform effectively as it functions primarily as a surface coverage plant. If given a constant source of water in a bog situation, it will get 2 - 3 inches tall. It will do well in the nooks and crannies of a 2" deep wet zone.
Clover is usually hardy. I'm not sure about this variety. I live in zone 8. My clover is in a terracota pot in my small garden pond. I plan to bring it inside during harsh weather. If you place the pot in a shallow container of water and keep it in a sunny location you can enjoy it inside over the winter.
Hi UNK! The previous answer is correct. All of our Pond Plants are already planted in DynaDirt Aquatic Soil and are well rooted so the soil is not prone to leaching out. All of your commercial "potting soils" almost always contain pine bark, vermiculite, etc which are things that will float, or leave the pot when placed in a pond under the water. I would not recommend using potting soil for this plant, rather an aquatic soil.
