Winter hardiness

Princess Lilies® are semi winterhard and they can bear some frost. If you do not cover up the plants, almost 70% will survive through the winter in The Netherlands. If you cover the plants with straw, almost all the plants will survive through the winter. Plants in a tub will freeze faster. To avoid this you must put the plants in a frost-free area during the winter. When the plants start to grow in the spring, give the plants extra fertilizer so they blossom sooner and more vigorous.
