Early Summer Cottage Garden flowers

At last the ground is warming up and the plants are putting on tremendous growth, making up for the cold early spring; alas hot on their heels are the weeds.  In an ideal world by now your borders should be so covered in flowers that weeds struggle to find room to grow.  The theory is good, but I still seem to be filling up wheel barrow after wheel barrow with cleavers, nettles and the infamous ground elder!

But here are a few treats from the early flowering summer borders:

Pink Hawthorn

Sambucus underneath a silver birch with pink persicaria 

The lovely tall white allium 'Everest'

I think this is Allium Aflatunense

The more unusal centaurea montana Purple Heart
