In the garden

Delphinium requienii sits within the Delphinium group (family Ranunculaceae) and is sold under the common name larkspur. Flowering takes place in the UK from June to August. Because it is harmful if eaten, handle plants with gloves and other protective equipment and follow the HTA guide to potentially harmful plants for pet contact details. Requirements vary across Delphinium species, so check the supplier’s notes or plant label for precise advice on site, soil and hardiness before planting. As a precautionary approach, allow good air movement around plants and consider support where stems are tall; these measures reduce physical damage and make handling safer. Remove spent flower stems if you need to manage seeding or tidy the bed. Use Delphinium requienii where its summer flowering can be appreciated and where access for safe handling is available; place it where spikes will be visible from paths or windows and away from areas frequented by children or pets. When buying, ask the nursery for cultivar-specific guidance so you can match the plant to your space and seasonal plan.
