Super Plug Plants - We have selected these plants to be grown where you would like something that bit different in areas such as hanging baskets, patio containers, tubs and raised beds. For best performance we recommend that you grow them on further, either in 9 to 11cm pots or in the final planting containers, maintaining a minimum temperature of 13-16°C (55-60°F). Allowing these plants to establish in this way before placing in their final position outdoors will pay dividends later in the season. Note: when planting, there is no need to remove any net or fibre pot sleeve.
