Tempted? Here are some ideal bog-garden candidates to consider...

Alchemilla mollis

This water-loving plant has fine delicate foliage but often toughs out wet situations.

Astrantia ‘Ruby Wedding’

Astrantia have long lasting feathery flowers and foliage and relish wet soils. A bucket of water every week in summer droughts won’t go amiss if the soil gets too dry.

Hemerocallis ‘Burning Daylight’

Day lilies are remarkably robust plants, with trumpet shaped blooms in bright warm colours from mid-summer.

Hosta (Tardiana Group) ‘Halcyon’

Although martyrs to slugs on occasion, if you can keep the leaves wholesome, hostas can be extraordinarily lush in summer, even in shade.

Iris sibirica ‘Tropic Night’

Iris sibirica

are very tolerant of wet soil and sweat out dry summer periods with ease, flowering for long periods in early summer and retaining delicate grassy foliage all summer.

Verbena bonariensis

This tall plant, prized for the misty effect of its flower spikes, is very tolerant of waterlogging in summer.
