Here's an amazing plant that can transform a damp, shady, neglected corner of the garden with its great beauty. 'Great' is an appropriate description as this is the largest of all the blue Hostas. It will slowly grow to form enormous clumps with grey-blue leaves up to 40cm (1'4) long. In early summer it produces white flowers on erect stems which grow up to 1m (3'3) high. Hosta 'Blue Angel' holds the RHS Award of Garden Merit for its excellent garden performance. Plantain Lilies prefer moist soil and a shady location. Height: 90cm (3'0). Spread: 1.2m (4'0).
Known for its glossy dark-green foliage and late summer deep-blue flowers, Caryopteris ?Petit Bleu? is a low-mounding, deciduous shrub with an elegant free-branching habit. Not only does the foliage and flower colour contrast well, providing the garden with a late summer splash of colour, this shrub is extremely attractive to butterflies and other beneficial insects, due to its nectar-rich blooms. What?s more impressive is that wherever you choose to site this superior cultivar, it will continue to produce a dramatic and eye-catching feature, especially when planted in a sunny spot. Height: 60cm (2?). Spread: 90cm (3?).
Clematis 'Blue Ravine' blooms in late spring/early summer, bearing huge 20cm lavender blue flowers with contrasting purple/red anthers, then again in late summer with slightly smaller flowers.

This Old Man's Beard variety is the perfect choice for containers, pergolas, trellises and even peering through garden shrubs. Height: 2.5m (8'). Spread: 1m (3'). Pruning group: 2.
A rather unique lobelia that is non-seeding, so it'll flower much longer in your summer displays.

Supplied as plug plants.
A compact, perennial scabious producing masses of lilac-blue blooms throughout the summer, above neat cushions of green foliage.

Now here?s something a little different for your garden! Sollya heterophylla is better known as the Bluebell Creeper. Its twining stems are cloaked in evergreen foliage that makes a splendid backdrop for its nodding sky blue flowers throughout summer.
A rare treat for any garden enthusiast, Acnistus australis 'Blue Angel's Trumpet' will give you a magnificent display of true blue trumpet shaped flowers during the summer. This tender, semi evergreen shrub is best suited to a conservatory or sunny patio as it will need to be brought in over the winter to protect it from frosts, but whilst it is in season it is certainly an impressive impact plant. The 2 - 3 inch (5 - 8 cm) blooms are produced in abundance and hang along the entire length of the branches, standing out beautifully against the dark green foliage. Stand a pot at the back of a flower border too and let it become the backdrop for your summer display.
