Delphinium bicolour is a species of larkspur known as little larkspur and low larkspur. It is native to northwestern North America from British Columbia to South Dakota, where it grows in mountain forests and foothill scrub and prairie. This is a perennial herb growing from a thickly branching root system. It produces solitary stems to 40 centimetres (16 in) in height and green with reddish bases. Most of the leaves are low on the stem and grow on short petioles. They are several centimeters long with many rounded lobes. The small inflorescence holds a few large flowers per stem. The flower has dark purple-blue sepals each about 2 centimeters long and a spur of 1 to 2 centimeters. The plant is poisonous to cattle, less so to sheep, and it is occasionally eaten by various species of wild cervids.
Little larkspur is fairly disease-resistant and generally not prone to illness. However, it can be affected by pests and diseases present in its surroundings. These problems are typically not severe. For care, this plant needs moderate maintenance. It should be pruned regularly to keep a neat appearance and healthy growth. Fertilizing can also encourage flowering. Little larkspur is suitable for anyone with outdoor space, such as a garden or patio, and does not require extensive care experience. It may need more attention when grown indoors.
How to keep Delphinium Bicolor.
Water
To have thriving flowers, little larkspur needs soil that is consistently moist. During dry spells, water the plants thoroughly, making sure the soil is damp at least 2.5 cm (1 inch) below the surface. However, be careful not to overwater, as this can lead to root and crown rot.
Pruning
Little larkspur produces beautiful blue flowers and benefits from pruning in early spring. To promote healthy growth, remove any damaged stems, thin out crowded areas for better light and air circulation, and trim spent flower stalks to encourage more blooms. Always use clean tools for pruning and try to align your efforts with the plant's natural growth cycle.
