As summer begins, there are a number of blue flowers appearing in the garden. My favourite colours are blues and purples, so it feels like a bit of a treat for me. The flowers I like best are those where the blue shades into a different blue or into a purple. There’s something about a colour being slightly mixed, rather than a solid shade, that makes it more interesting to see.
The plant above is Cerinthe major ‘Purpurascens’, aka Honeywort (or the ‘Blue Shrimp Plant’ in the USA). It’s normally an annual, but if the winter is mild enough it can survive into the next year. That’s what has happened here, so this year we have a much larger plant than we usually would.
This plant is one I particularly like for the deep blue bracts that surround the small purple flowers. The blue bracts are made more attractive by the way they are tinted with purple or green – here even the stem has a blush of purple. The colouring is more intense when it’s cold, so this has been at its best over the cool spring months. I’ll be interested to see if the colours become paler as the summer weather heats up.
A simpler colouring is that of the Baptisia australis or ‘False Indigo’ (above). Less complex than the Cerinthe maybe, but it is a lovely shade of deep violet-purple that I find quite irresistible. It’s an easy plant to grow here because it copes well with drought and it is often suggested as an alternative to lupins. For me, the Baptisia is certainly the easier choice, as lupins struggle very unhappily here and I’ve managed to lose a few.
Clematis ‘Arabella’ (below) has flowers that are a mauve shade when they first open, gradually becoming more blue as they age. So the one plant can have a wide variety of flowers at the same time. (In fact, when I looked at it today, for a moment I thought there was a purple clematis growing beside it, so dark were the newest flowers.) The soft blending of mauve and blue shades in Arabella’s petals delights me. That means there’s good chance that I’ll be trying to grow this small clematis elsewhere in the garden too.
Soon, these beauties will be joined by different shades of blue, as the flowers of campanulas, scabious, geraniums and catanache start to open. I’m looking forward to some summer blues!
