Anchusa azurea - 'DROPMORE BLUE'. I love blue flowers and the Anchusas are so beautiful.
Salvia superba 'Blue Queen' - Excellent garden value on account of its dwarf habit (40cm) and long lasting rich blue flowers enhanced by dark purple bracts. Best grown in full sun.
Stonecrop 'Ruby Glow' herbaceous perennial forming a low clump of spreading deep red stems to 25cm in height . Summer flowering. Grow in moderately fertile, well-drained, neutral to slightly alkaline soil in full sun. A drought-tolerant plant
Libertia grandiflora a lovely white flower on an evergreen foliage, perfect for the front garden. Will look great with Heuchera and grasses.
