I wonder if it's possible to have too much blue in the garden?
Borage, Borago officinalis is a true blue, anyone for Pimms?
I have it growing amongst pink Japanese anemones but may have to pull a few as it's vigorous and threatening to swamp them.
The first blooms of Cape Leadwort, Plumbago auriculata. I've seen this growing all over the south of France, huge specimens cascading over rock walls down in Provence, it just sings 'Summer' to me.
Geranium 'Jolly Bee'. Proven Winners describe it as having a 'Superior mounding habit compared to Rozanne'. I really don't know about that, but beautiful it is all the same and promises to bloom until Autumn.
Geranium 'Johnson's Blue'. Although it has a shorter flowering period than some, I think the colour is incomparable. I'm going to cut it back hard when the flowers have gone over, give it a feed and see if it'll bloom again by September.
Ground morning glory, Convolvulus mauritanicus. I love this plant, a real doer. It positively welcomes this current ninety degree heat, flowering unswervingly in the sun until dusk when the
the little saucer shaped flowers recoil into tight little cones, characteristic of all convolvulus.
Wildflower 'Vipers bugloss', Echium vulgare seeds itself around here and there. I'm quite happy for it to appear under the kitchen window as shown above.
Campanula muralis blooms profusely through June and then fits and starts through the rest of the season. It seems happy in sun or shade and spreads readily.
Hosta 'Wide brim'. In all honesty perhaps not the prettiest blue, really grown for its foliage but there it is, all the same. Behind are 'touch me nots' or Indian balsalm which although volunteer a bit too readily I find easy to pull, so any unwanted seedlings are swiftly gone.
Nepeta 'Walkers low'. I reckon catmint is possibly the most versatile perennial. It's hard to make a mistake with it.
Clematis Jackmanii. Ok, not really blue, purple in reality but still, a wonderful colour.
