I have replanted them all in a large planter and kept them indoors while the nighttime temperatures are very low. They are magnificent, they have grown and are already blooming. Transplanting is scheduled in 8 days.

Description

Lobelia erinus 'Crystal Palace' is a variety of lobelia that is particularly compact and bushy, essential for ornamenting hanging baskets and summer planters. Its numerous flowers, of a vibrant blue-violet colour, resemble small butterflies. They bloom continuously from June to September, almost hiding the spread of olive-green foliage leaning towards bronze. Its cushion-like habit brings volume to floral compositions.

'Crystal Palace' Lobelia is a plant from the Campanulaceae family, of horticultural origin. This variety is derived from, among others, Lobelia erinus, an annual species of South African origin that has become essential in container gardening. Its many branched stems form a very tight ball, 10-15 cm (3.9 - 5.9 in) high and 15-20 cm (5.9 - 7.9 in) wide in just one season. Its small alternate, obovate, and slightly crenate leaves form a background for its multitude of medium-sized flowers that bloom throughout the summer. As they elongate, the flower spikes bear clustered flowers. Their corollas measure 2 cm (0.8 in) in width and 1.8 cm (0.7 in) in height, composed of 2 very delicate upper petals and 3 larger lower petals. They are regularly visited by pollinating insects.

'Crystal Palace' Lobelia suits being alone in a pot, brightening every corner of courtyards and terraces. For a very romantic feel it blends well with the pastel shades of pink, mauve, sky blue, or white varieties. It will also harmonize with the softness of petunias, the silvery foliage of Helicrysum, and the whiteness of verbena. Its intense blue hue also contrasts pleasantly with the pale yellow of Bidens, Vanilla Marigolds, or Million Bells Lemon Petunias, especially since its exuberant growth is not likely to be overshadowed by those more cumbersome neighbors. You can even plant it at the edge of a bed, especially if you have a small garden, preferably in the sun (not scorching), but also in partial shade. The fascinating spectacle of its flowering never tires; this small plant will always find a place near the house.

Please note that our young plants in mini-plugs are professional products intended for experienced gardeners: upon receipt, transplant and store them under shelter (veranda, greenhouse, frame) at a temperature above 14C° for a few weeks before planting outside once all risk of frost has passed.

Planting and care

'Crystal Palace' Lobelia is a tender plant, so install it outdoors once the risk of frost has passed. Choose a sunny or partially shaded site. This annual Lobelia prefers a well-drained, light, moist, and humus-rich soil. Water regularly, adding fertiliser every two weeks to the watering can. After each flowering period lightly prune the stems to stimulate new blooms. You can also take cuttings at this time.

Lobelia prefer partial shade and soil that stays moist, they flower much more generously under these conditions. You can plant them from April as they can tolerate temperatures close to freezing, which will darken their leaves. Leave at least 20cm (7.9 in) spacing between each plant in open ground.
