Larkspur 'Shelby' (Delphinium 'Shelby') brings a palette of lavender to the garden. Among its distinctive details: semi-double flowers. The foliage features shades of green, to be highlighted among different textures. The usual flowering period is June-August. Its size of 60 cm by 50 cm reserves it a place in the middle of a flower bed and for group plantings, without forgetting the space for its neighbors.

To plant Larkspur 'Shelby', look for the following exposure: sun to partial shade and suitable soil (humus-rich, retaining its freshness during growth, without stagnant water around the collar). For Larkspur 'Shelby', regularly check the soil around the root ball: it must remain fresh. Water at the base when the surface begins to dry and adjust watering according to rainfall; this exposure (sun to partial shade) does not eliminate water needs. A margin corresponding to its spread of 50 cm avoids having to move the clump in the first seasons. The indicated hardiness zone is 3, to be assessed according to your garden's conditions.

The maintenance of Larkspur 'Shelby' relies mainly on observing the clump: after flowering, remove the spent flower stalks above healthy foliage and continue watering as appropriate for the soil. The tall spikes of delphinium may require support in windy areas; plan for this before they are fully developed. For pairings, consider echinaceas, campanulas, and perennial geraniums in varieties with similar needs. Keep its 60 cm height in mind to place lower plants on the right side and allow the flowers to be visible during June-August.
