Many nectar flowers bloom in March, enabling bees, butterflies and hummingbirds--which all need nectar to survive--to find their way to suitable flowers sooner than ever before. Putting out feeders is good, but planting flowers that offer these insects and birds nectar is even better. Bees and butterflies are pollinators, so if you or a neighbor are growing vegetables or fruits, planting flowers to attract pollinators is a real plus.
Daffodils are one of many nectar flowers that bloom in March. Some may bloom as early as late February depending on where you live and how cold your winter was. Daffodils come in a variety of colors besides yellow. You can find white, peach and even pink cultivars. There are also a variety of flower shapes, including doubles and split-corona.
Daffodils are one of the few bulbs not bothered by deer, squirrels, voles, woodchucks, gophers or other critters, because they contain alkaloid chemicals, which make them both bitter tasting and toxic.
Hellebore is a must have for anyone who wishes to have flowers blooming almost year-round in their garden and especially to those who wish to have nectar flowers that bloom in March. Even in the Midwest, there are varieties that will begin blooming in mid-November and continue blooming into early summer, sometimes longer.
Hellebore nectar is attractive to a variety of bees. The plants are seldom bothered by pests or disease--with the exception of the occasional case of black spot or an infestation of aphids. Leaves infested with black spot should be removed and thrown away, not composted. Aphids are a tasty treat for ladybugs. If you do not have ladybugs in your garden, the aphids will attract them. An alternative is to use an insecticidal soap to rid your plants of aphids.
Nothing beats the bright yellow, lemon-scented flowers of winter aconite for gardeners wishing to plant something that is both fragrant and early blooming. Winter aconite begins blooming in February and will continue for several months depending on your climate. Once the temperature begins to heat up, these plants will die back.
Winter aconite makes a great ground cover for the shade garden, helping to keep weeds down and soil moist until other plants begin to emerge. The flowers are very attractive to a variety of bees and the hoverfly, making winter aconite a wonderful choice for nectar flowers that bloom in March.
