Look out in woodlands at this time of year for foxgloves, one of the first wild flowers to colonise newly-felled woodland.
A single plant can produce over 7,000 seeds, which can lie dormant for decades and only bloom when the light reaches them. They flower in their second year onwards.
Its chemicals are dangerously poisonous but can also treat heart failure in the form of digoxin.
The caterpillar of the Foxglove Pug moth selects a foxglove flower and using sticky silk thread it seals the opening and eats the insides until it pupates. Flowers with a resident Foxglove Pug remain on the flower stalk long after others without a caterpillar have died.
