The best blue hosta there is, and thick enough in the leaf that slugs mostly give up.

    About this plant

    Most blue hostas fade to green by July. Halcyon holds its colour into August because the waxy coating on the leaf is thicker — which is also why slugs find it harder work than the thin-leaved varieties.

    It wants shade to keep the blue. In more than about two hours of direct sun the wax breaks down and you get a green hosta, which is a perfectly nice thing but not what you paid for.

    Deer eat hostas. If you have deer and you want hostas, you need a fence or a spray programme; there is no resistant variety, whatever the tag says.

    Looking after it

    Water
    Consistent moisture; they sulk when dry
    Soil
    Rich and humusy. Compost every spring
    Slugs
    Iron phosphate bait in April before they get going
    Division
    Every five years, early spring, before leaves unfurl

    Plant it with

    The native ground cover for dry shade under maples, where almost nothing else will go.

    Serviceberry

    A small native tree that earns its space four times a year — and the berries are worth eating.

    Ostrich Fern

    Fiddleheads in May, a metre and a half of green architecture by July.
