Plantain lily

'So Sweet' is a medium-sized hosta with oval-shaped, mid-green leaves which have wide creamy white margins. In mid- to late summer, it bears fragrant white flowers, which are produced more profusely when it is planted in a sunny spot. Hostas benefit from plenty of organic matter being added to the soil before planting. They also enjoy being mulched in spring and autumn to help retain moisture in the soil. For the lushest displays, feed with a balanced fertiliser between March and June. Do not feed after this period or you will encourage the sort of sappy growth that slugs adore! To avoid the leaves looking like a piece of lace, take measures against slugs and snails, such as beer traps.
