Ageratum - Dwarf Ball Mixed
Fluffy clouds of blue, pink and white blooms hold aloft compact mound-shaped plants, perfect for adding drifts of colour to borders or containers.
Sow seed on the surface of the compost and cover with a very fine sprinkling of dry vermiculite or finely sieved compost. When the seedlings are large enough to handle, transplant them individually into 7.5cm pots or multi-cell trays. Gradually acclimatise plants to cooler conditions by putting them outside for a few hours a day for a few weeks.
