El Delphinium gracile It is a herbaceous plant of the genus Delphinium popularly known as guinea pig, espuelilla or delphinium. It tends to be confused with the plant of the same genus called Haltertum, because they both grow in the same place. It is found in the wild, dispersed in regions of the Iberian Peninsula and also in North Africa.
Delphiniums require regular watering, specifically during the dry summer months. Soil should stay just barely moist and never dry out, nor become soggy. Apply a balanced liquid fertilizer every 2-3 weeks. Apply a thin layer of compost in the spring as well as a 2 in.
Trim back the entire delphinium plant to within 1/4 inch of the basal leaves at the base of the plant. Dispose of the old stalks and stems in a compost pile or bin. Severe cutting back in early summer may encourage a second flush of bloom, especially on perennial varieties.
