With Delphinium 'Princess Caroline', the flower bed welcomes a plant whose flowers feature shades of pink, salmon, and red. The foliage presents shades of green, to be highlighted among different textures. The usual flowering period is June-July. The clump reaches about 90 cm in height and spreads 60 cm; use these dimensions to place the plant in the middle of the flower bed and for group plantings.
The success of Delphinium 'Princess Caroline' begins with its location: sun to partial shade, in suitable soil (humus-rich, retaining moisture during growth, without stagnant water around the collar). For Delphinium 'Princess Caroline', regularly check the soil around the root ball: it must remain moist. Water at the base when the surface begins to dry and adjust water supply according to rainfall; this exposure (sun to partial shade) does not eliminate water needs. A margin corresponding to its 60 cm spread avoids having to move the clump in the first seasons. The indicated hardiness level is zone 3, to be assessed according to your garden's conditions.
In a planting of Delphinium 'Princess Caroline', after flowering, remove spent flower stalks above healthy foliage and continue watering according to the soil. Large delphinium spikes may require support in windy areas; plan for this before they fully develop. For companion planting, consider daylilies, perennial geraniums, and echinaceas in varieties with similar needs. The flowering period (June-July) and the 60 cm spread will serve as benchmarks for distributing other plants around this plant.
