There are many spring flowering plants attractive to bees which will bloom from late winter through to spring. As the bees emerge, they are looking for food. Growing some of these plants in your garden will help the bee population. This is particularly true of the very early spring flowering plants, such as Pulmonaria and Hellebores, which provide food when it is scarce. One of the best garden sounds is early in February, the gentle buzz of an emerging solitary bee which has found the Pulmonaria.
Bees are a critical part plant's growing cycle. As bees travel around the garden, they pollinate flowers by the transfer of pollen from the male parts of a flower to the female parts of a flower of the same species, which results in fertilisation of plant ovaries and the production of seeds. The best and busiest of pollinators are bees, and so they are very important.
In the images above are Bluebells, (left) which look lovely in a natural setting. These are English bluebells Hyacinthoides non-scripta as compared with the Spanish bluebells, which may look similar but are an invasive non-native species. (For information on how to tell the difference, and how to grow Bluebells.)
Centre image is a Hellebore and far right, the familiar forget-me-not, latin name Myosotis. All of these plants are easy to grow, in the case of forget-me-nots, too easy as they are prolific self seeders. It is important to thin them out which is easily done, but they need to be checked.
