Larkspur is a plant, which is a part of the buttercup family. This is a flower that returns annually blooming from summer through fall. The plants will flower until the first frost. The flower grows best in areas that are cool with moist summers. The flower is a vertical bloom that is of an irregular shape and grouped on the end of the plant's stem. The flower is a combination of petals and sepals that can hold colors from blue to violet. Each flower is densely packed on tall stems and between 1/4 and 1/2 inch in size. Some leaves have a fern-like appearance while others are thin with pointed tips in a medium to dark green. The stems are long with the flowers that bloom at the top of the stem. This is a flower that is good for the garden, boarding the driveway or walkway and the type of flower that can be cut for table vases. It first was introduced in 16th century England from Italy and became one of the most common flowers in gardens. The flower is easy to grow and will tolerate most soil types but grows best in light draining soil. Heavier soils should be mixed with compost, and in areas known for windy conditions, the stems may need to be staked or grown along a fence.
