There are two main types of water lilies available out there in the market – Tropical and Hardy Water Lilies.
Hardy Water Lilies are perennials; they’ll come back year after year. They come in numerous colours and forms, ranging from yellow to pink to red. The Comanche species of water lilies changes the color of its flower from an apricot to a dark bronze laced with red. Leaves and flower sizes range between 3 and 12 inches in diameter.
These varieties are mainly best for northern climates that experiences a cold winter. Hard water lilies are aptly named as they are able to combat the harsh and tough winter days – as long as their roots don’t freeze entirely. If they are planted with at least 17 inches of water above their root system, they will pull through . Otherwise you could always put them in cold storage, but remember to keep them moist.
