Very disappointed with the delivery Plastic wrap encircling the container, stuck to the plants which were a bit dried out and not very vigorous. I had requested an eco-friendly container!!!!

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.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
