Red Larkspur

Red Larkspur is the named Delphinium ‘Red Lark’ selection, with semi-double, light-red flowers held on upright stems above medium-green foliage. Its outdoor bloom is reported from late spring into summer, bringing a clear seasonal accent to a sunny perennial planting. ## Flowers and placement The cultivar’s patent describes a moderately vigorous, upright plant and records its light-red flower color and breeding from two selected Delphinium parents. The patent’s measurements are from greenhouse-grown one-gallon plants, so they are not a promise of mature garden dimensions. [Cultivar patent](https://patents.justia.com/patent/PP29761) Give Delphiniums a sunny, sheltered position with fertile soil that stays evenly moist but drains freely. The [Royal Horticultural Society’s Delphinium profile](https://www.rhs.org.uk/plants/5399/delphinium-grandiflorum/details) offers general genus-level cultivation guidance; it is not a size profile for ‘Red Lark’. ## Maintenance Water during dry spells and use a stake where wind could bend the flowering stems. Remove spent flower stems after the display and keep the crown from sitting in water. Check the plant periodically for slugs and other garden pests, especially as new shoots emerge.
