Botanical nameDelphinium
Delphinium ‘Blue Fabulosa’, known in the garden as Larkspur ‘Blue Fabulosa’, combines blue and white blooms with a volume that is easy to place in a composition. Among its distinctive details: semi-double flowers. The foliage has green hues, to be highlighted among different textures. The usual flowering period is June-August. At maturity, expect 60 cm in height and 50 cm in width, which suggests its use in the middle of flowerbeds and group plantings.
Soil choice is essential for Larkspur ‘Blue Fabulosa’: humus-rich, retaining its freshness during growth, with no stagnant water around the collar. The preferred exposure is sun to partial shade. For Larkspur ‘Blue Fabulosa’, 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 spacing of about 50 cm between centers is a starting point, to be adjusted according to observed vigor. The indicated hardiness level is zone 3, to be assessed according to your garden's conditions.
The maintenance of Larkspur ‘Blue Fabulosa’ primarily relies on observing the clump: after flowering, remove spent flower stalks above healthy foliage and continue watering adapted to the soil. Large delphinium spikes may require support in windy areas; plan for this before they are fully developed. For associations, consider campanulas, perennial geraniums, and daylilies in varieties with similar needs. By composing around its volume of 60 cm by 50 cm, you will preserve the visibility of its blooms (June-August) and circulation between plants.
