Flower color: bright blue.
Natural flowering period: July - September (blooms in the first year).

This tall plant with decorative foliage and elegant blue-violet spike-shaped inflorescences sets a peaceful mood and encourages calm contemplation. Lobelia is ideal for creating spectacular color spots in flower beds, borders and groups.

Sowing: for seedlings in March-April. 1.0 g = 32000 seeds.
After the appearance of the first two true leaves, the seedlings are pricked out. It is better to prick out small groups of several seedlings. They are planted in open ground in May-June, when the threat of frost has passed. The distance between plants is 10-15 cm. Any moist garden soil rich in humus, sunny or semi-shaded location is suitable.
Care: for abundant and long flowering, periodic fertilizing and good watering in dry weather are necessary. For fertilizing, use a complex mineral fertilizer that provides the necessary nutrition to flower crops. In August, the plants need to be cut low, fed, loosened and watered, then the second flowering will begin, which will last until frost.
Flowering: July-October.
