I plant Nasturtiums every year. I love the bright flowers and their distinctive smell – a spicy sort of peppery scent. Their leaves are attractive too. Nasturtiums sprawl and climb and are brilliant for ground cover and filling gaps.
Some people loathe them I know that.
There are plenty of butterflies around this summer including some spectacular Peacock butterflies. They like hedgerows and woodland edge type habitats and will happily visit your garden to feed on some of their favourite garden plants such as Buddleja and Verbena which have many tiny tubular flowers arranged in clusters.
