Recently introduced to gardens and a hit Chelsea Flower Show, Lysimachia ‘Beaujolais’ feature flower spikes of deep claret which bloom continuously from May to September.

Matthiola incana 'Sweetheart' with the delicate pale-pink blooms is a variety that is traditionally grown for the floral industry. They can be sown early in spring to give a good summer flower display or can be treated as biennials. Seedlings started inside in October will have the flowers ready for Valentine’s Day.

Penstemon barbatus 'Twizzle Coral' adds a graceful twist to the garden. A first year flowering perennial, that is hardy and vigorous, it boasts twice the length of flowering stems, giving longer, more elegant wands for the vase while preserving the natural elegance of Penstemon barbatus.

A winner of both an AAS and Fleuroselect Awards, Penstemon ‘Twizzle Purple' is a first year flowering perennial that boasts twice the length of flowering stem. Strong, trouble-free plants produce trumpet shaped magenta-violet blooms that flutter all along tall, slender stems.

Russian Sage is one of the great garden plants of all time, but if you've been frustrated by their floppy nature, this new variety will be a welcome addition. Growing to about 60 to 75cm tall, Perovskia atriplicifolia 'Taiga' is also the first Russian sage available as a first year flowering perennial.

Potentilla 'Helen Jane' is a beautiful new semi-dwarf cultivar that displays gorgeous crimson-eyed, bright pink flowers, with petals that are attractively crinkled just like crepe paper. Flowering over a long period, new buds open repeatedly in a long succession, from late June to September.

Venerating a former plant curator at the Royal Botanic Garden in Edinburgh, Scotland, 'Ron McBeath' is a beautiful new semi-dwarf cultivar. This diminutive potentilla repeat-flowers for months, sending up wands of rosy carmine flowers even in shade. It outlasts other potentillas by far.

An absolute gift to flower arrangers, this is a noble and ornamental plant for the back of any border making nice clumps of foliage. It is, of course, the flowers that are remarkable: three or four inches across, “green” is one’s immediate impression on seeing them.

'Fama' is a most elegant flower. With long stems and intense blue blooms, it is the largest flowering and most uniform strain of the Blue Pincushion. They mature into dense tufts of lance shaped, grey-green leaves from which arise a beautiful display of intense lilac-blue flowers each with a silvery centre.
