Perennial bulbs will emerge and continue to bloom year after year. Naturalising bulbs will also emerge every year but will also increase in number. Flower bulbs are divided into three groups: annuals, perennials and naturalising bulbs. Annual bulbs will produce their most beautiful display during the first year after planting and will also emerge the next year. Over time, they will no longer flower at all.
