Delphinium 'Red Lark'

Delphinium ‘Red Lark’ is a captivating variety in the delphinium genus, prized for its bold and unique coral-red hues, which stand out in contrast to the traditional blues and purples commonly associated with delphiniums. This plant is a true showstopper in any garden, offering a refreshing splash of color to traditional garden landscapes.

Growing to 30-36 inches (75-90 cm), the ‘Red Lark’ becomes a natural focal point, especially when planted amidst lower-growing plants. Blooming in early summer, its elegant spikes are densely packed with semi-double, vibrant coral-red flowers.

Regular deadheading can encourage a second bloom in late summer or fall, prolonging its ornamental value through the season.
