Bloom Time and Flowering Characteristics

The GIANT Imperial Mix produces its spectacular flowers during mid to late summer, typically blooming from June through August depending on your planting time and local climate. The flowering period can be extended by deadheading spent blooms, encouraging the plant to produce additional flower spikes throughout the season.

Each flower spike is densely packed with individual florets that open progressively from bottom to top, creating a long-lasting display of color. The flowers are naturally attractive to pollinators like bees and butterflies, making them a wonderful addition to gardens designed to support local wildlife.

Harvesting for Cut Flowers

One of the greatest pleasures of growing GIANT Imperial Mix larkspurs is their exceptional performance as cut flowers. Harvest spikes in the early morning when the lower florets are fully open but the upper buds remain tight—this ensures the longest vase life. Cut stems at an angle and immediately place them in cool water with flower food.

Larkspurs can last up to two weeks in a vase when properly conditioned and maintained. Remove lower foliage that would sit below the waterline to prevent bacterial growth and keep water fresh by changing it every few days.

Color Combinations and Arrangements

The mixed color palette of the GIANT Imperial Mix offers endless creative possibilities. The blue and purple tones provide a cool, calming aesthetic, while pink and white varieties add softness and brightness. Many gardeners enjoy growing multiple plants to ensure they have a good distribution of colors for both garden display and cutting arrangements.

In floral design, larkspurs serve as excellent filler flowers and focal elements. Their tall, airy structure works well in both traditional and modern arrangements, adding movement and dimension to any composition.
