Penstemon 'Heavenly Blue' is a striking perennial with tall spires of soft blue flowers, each with a pale throat that adds depth and contrast. Flowering from early summer to autumn, this variety brings a refreshing, cool-toned colour to borders, gravel gardens and cottage-style planting schemes.

The neat, upright habit makes it a perfect choice for adding height and movement to garden beds, while its long flowering season ensures months of interest. Easy to grow and low maintenance, it is ideal for gardeners of all experience levels and is a magnet for bees and butterflies.
