Eryngium

The Sea Hollies. Summer flowering architectural plants with interesting and often colourful bracts surrounding the many flowers, very attractive to butterflies and insects and providing a spiky skeletal foil against which other summer flowering plants look great. These are supplied as established plants in a 1 litre pot and may take a year to reach their full stature. Aim to get them established in sunny conditions so that they will in time have to ‘work’ to survive, Growing them ‘hard’ results in stronger and more flower filled plants in due course and a sunny summer helps turn the flowers more blue.
