The most economical way to grow flowers and vegetables is to start them from seed or plant bulbs. Those gorgeous beds of tulips and daffodils you see in springtime are the result of planting flower bulbs in the fall. In the right climate, these natural perennials will come back every spring. In a challenging climate, you can treat them like annuals and replant bulbs each fall. Another favourite that grows from a bulb is gladiolus, but these are planted in the spring, once the earth has warmed, for full bloom in the summer. For spectacular summer colour, try spreading wild flower seeds in bare patches of the garden. Hummingbirds and bees will love them.
