Blue is the rarest colour in the garden, which is exactly why a genuine blue flower stops you in your tracks. These are the plants that bring it.
18 products
True blue is unusual in nature, so most gardens have very little of it. That scarcity is the appeal. A drift of real blue reads as cool and calm, pushes the back of a border further away, and makes yellows and oranges sing when you plant them nearby.
The plants here range from low, spreading types for the front of a bed to taller spires for the middle. Many prefer sun and open ground, though a few of the woodland kinds take some shade. Grouping several together gives the strongest effect, since blue can get lost when it is dotted about on its own.
All grown for UK gardens and sent out well rooted.
Genuinely blue flowers are less common than the photos online suggest, since many so-called blue plants lean purple. Each plant page here describes the real colour honestly so you know what you are getting.
Most do best in an open, sunny spot, which brings out the strongest colour. A few woodland types tolerate part shade. Check the aspect listed on each plant.
Blue and yellow is one of the most reliable pairings in gardening, each making the other brighter. Blue also cools hot borders and sits beautifully with silver foliage and white flowers.
The ones here are chosen to cope with UK conditions. Hardiness varies by plant, so check the rating on each page if your garden is cold or exposed.
