Hostas enjoy the cool, north-facing Well-yard, at the back of the house - and slugs and snails are foiled by growing them in pots and chimney-pots. The Early Purple Orchids in the trough seeded themselves in and have mutiplied over the years with no human intervention.
Cardiocrinum giganteum is certainly an exotic inhabitant of The Brown House Garden. It's waxy cream trumpets give off a heady perfume which fills the Well-yard on warm summer evenings. We had one plant, a few years since, which reached 9 feet, but this year it's flowering at only about four feet. The plants die after flowering, but leave off-set bulbils which, given time, will themselves flower.
