About Siberian larkspur
Delphinium grandiflorum, also known as dwarf Larkspur, is a charming perennial plant from the Ranunculaceae family, valued for its vibrant spikes of blue or purple flowers. With a more compact habit than other Delphinium species, it is ideal for the front of flower beds, borders, or in pots, adding a touch of intense color and verticality. Its delicate flowers, often with a white 'eye', attract pollinators and create a beautiful contrast in the garden.
Native range
East Asia, specifically Siberia and China
Care tips
It prefers full sun or light partial shade in very hot climates, with well-drained soil rich in organic matter. Keep the substrate consistently moist, but avoid waterlogging, especially during flowering periods. A common mistake is not providing good drainage, which can lead to root rot; ensure the soil does not retain too much water. It benefits from deadheading to encourage continuous blooming.
How to save a dying Siberian larkspur

- What kills it
