Delphinium is a beautiful, tall perennial plant that belongs to the Ranunculaceae family. The name delphinium comes from the Greek word “delphis,” which means dolphin, because the shape of the flower resembles the Bottlenose dolphin. It is commonly known as larkspur or bee larkspur.

Delphinium flowers can range in colour from deep blue and purple to pink, red, and white. The flowers grow in long spikes, creating a dramatic, vertical display in the garden. They are also often used in floral arrangements due to their striking beauty and unique shape.

Delphiniums prefer a moist, acidic soil with plenty of organic matter. They do best in full sun but can tolerate some shade. They grow well in USDA zones three through seven, making them a popular choice for Northern gardens.

One of the most crucial factors in growing delphiniums is providing them with adequate support. These plants can grow up to six feet tall, and the weight of the blooms can cause them to topple over. For this reason, you should stake them from the time they are young plants. You can also plant them near a fence or wall for added support.

Another essential aspect of growing delphiniums is deadheading. Deadheading involves removing spent blooms to promote more flowering. Delphiniums are prolific bloomers and will continue to produce new flowers all season long if you continually remove old blooms.

Delphiniums are prone to a few different diseases and pests. One of the most common issues is powdery mildew, a fungal disease that can turn the leaves white and powdery. You can help prevent powdery mildew by providing good air circulation around the plants, avoiding overhead watering, and removing infected plant material promptly.

Another common pest that affects delphiniums is the aphid. These small, green insects feed on the sap from the leaves, causing them to wilt and yellow. You can control aphids by spraying the plant with a strong stream of water or applying insecticidal soap.

Despite these potential issues, delphiniums are relatively easy to grow and provide a show-stopping display in the garden. They are a popular choice for cottage gardens, perennial borders, and cutting gardens.

In conclusion, delphiniums are a beautiful and graceful addition to any garden. They are easy to grow, provided you provide adequate support and perform regular maintenance tasks such as deadheading. If you are looking for a tall, dramatic plant with striking, unique flowers, consider adding delphiniums to your garden. With their bold colours and impressive height, they are sure to make a statement wherever you plant them.
