Blue de Blue
For some reason, Blue seems to be the hardest colour to find in flowers. Our garden has a few blue flowers and I treasure them. Here are a few of them.
Siberian Bellflower (above) is a heavy flowering midget that adapts well to growing against a rock or along a fence.
Clustered Bellflowers come out in late June and are definitely one of my top picks for a blue flower.
The Peach Leafed Campanula comes both in blue and White. I have both but prefer the blue. It begins to flower mid-June.
Ajuga is more of a groundcover plant, but in the late Spring, it produces masses of short blue spikes.
Brunnera is an attractive plant that has lovely heart-shaped leaves, which can be solid green or have pretty silver-white patterns in them. It produces striking blue flowers which are similar to Forget-Me-Not flowers.
In the late Spring, one of my clients has a garden full of the Virginia Bluebells. They look lovely and they tend to be somewhat invasive, so as soon as they stop flowering, she wants me to pull them out.
