Description

The Lobelia erinus 'Regatta Deep Blue' is distinguished by a very beautiful habit, both dense and trailing, perfectly suited for hanging baskets. It is an early variety, with deep blue flowers, capable of flowering continuously from June to October. This annual plant creates enchanting and long-lasting displays, even in the sun, confidently filling hanging baskets and balcony planters. Essential in summer compositions!

The 'Regatta' Lobelia is a beautiful improvement of the 'Cascade' lobelia, which will flower approximately 15 days earlier. It is a plant of the bellflower family of horticultural origin. It comes from the Lobelia erinus var. pendula, a South African annual species with a trailing and not upright habit. The numerous quite long and branching stems of this 'Regatta Deep Blue' variety form in one season a slightly trailing bushy clump, 20 to 30 cm (8 to 12in) high and at least 30-35 cm (12-14in) wide. The very small evergreen, alternate, obovate and slightly crenate leaves compose a beautiful dark green background for the multitude of flowers that renew themselves for almost 5 months. As they lengthen, the spikes bear flowers in clusters. Their corollas measure 0.5 mm (0in) to 1 cm (0in) in width. They are tubular before widely flaring out, observing a bilateral symmetry. The upper lip is composed of two raised tufts and the lower lip is divided into three larger petals, fused at the base. The throat is generally white, highlighting the color of the rest of the flower. This flowering is regularly visited by pollinating insects. It is not uncommon for Lobelias to self-seed: the young plants, which do not tolerate cold, will spend the winter in a bright room kept frost-free.

The 'Regatta Deep Blue' Lobelia works wonders in hanging baskets, pots, illuminating every corner of courtyards and terraces with its intense flowering. It blends with white and pink varieties, in a very romantic spirit, also harmonizing with the softness of petunias and surfinias, the silver foliage of 'Silver' Helicrysum petiolare (Gnaphalium), and the varied colors of Verbenas. You can even plant it as a border plant, especially if you have a small garden, preferably in sun or partial shade. The fascinating spectacle of its flowering never tires, it always surprises; this little plant will surely find a place near the house.

Planting and care

The 'Regatta Deep Blue' Lobelia is a tender plant, so plant it outdoors once the risk of frost has passed. Choose a sunny, non-burning location or partial shade. The annual Lobelia appreciates well-drained, light, moist, and humus-rich soil. Water regularly and add fertilizer every two weeks to the watering water. After each flowering period, lightly prune the stems to stimulate new flowering. You can also take cuttings.

You can plant them in pots or in the garden from April onwards, as they can tolerate temperatures close to freezing, which will cause their leaves to darken. Allow at least 40 cm (16in) spacing between each plant when planting them in the ground.
