Lobelias usually burn out quickly during the summer, but this unique mix solves that problem by blending a handful of earlier varieties from days gone by with the newer, longer-lasting varieties. The result is a rich, extra long-lasting colour carnival. A successful blend of old and new. Trails to: 30cm (12"')

Flowering Months
Feed and water lobelia plants frequently throughout the summer to promote an endless supply of delicate lobelia flowers. Caution: irritant to skin and eyes.
Lobelia plug plants can be planted directly into flower pouches. For baskets, beds and window boxes, pot up plugs and grow them on in warm, frost free conditions for transplanting at a later date. When all risk of frost has passed, gradually acclimatise lobelia plants to outdoor conditions over a period of 7 to 10 days before transplanting them into their final containers in any, well drained soil, in a sunny or semi-shaded position.
