Lobelia (Trailing) - White Cascade
So bright and effective is this lobelia that a hanging basket filled only with White Cascade gave one of the finest displays T&M had ever seen.
Sow late winter to mid spring at 18-24C in a good seed compost. Sow seed on surface of compost and gently firm down compost. Keep soil damp but not wet. Do not exclude light, sealing in a polythene bag after sowing is helpful. Germination usually takes 14-21 days. When seedlings are large enough to handle, transplant in bunches of 3 or 4 per 7.5cm pot and grow on in cooler conditions. Plant up into containers or hanging baskets and leave for 1-15 days before moving out of doors.
