Lobelia Cascading Waterfall Ice Blue is a superb variety for continues flowering and brilliant weather resistance. This variety is raised from cuttings and is completely sterile, so the plants will not be setting seed. Being sterile means, you benefit from the plants growing more flowers and for a period of 4 months. This variety is perfect for planting in baskets, window boxes and flower pouches. Height: 15cm (6”). Spread: 45cm (18”). 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. Feed and water lobelia plants frequently throughout the summer to promote an endless supply of delicate lobelia
