The Award of Garden Merit (AGM) issued by the Royal Hoticultural Society (RHS) helps gardeners find reliable, consistent plants that will provide particularly good value in the garden.The award is granted after trials at the RHS’ garden at Wisley in Surrey and/or assessment at specialist collections or discussion at meetings. There is a set list of criteria that plants have to meet to be deemed worthy of the AGM. For more information on the AGM please visit the RHS Website.
Nursery owner, Tim Fuller, has been involved with judging the trials at RHS Wisley since 2008.
The super, spring flowering hardy perennial pea relative. Low clumps of deep green foliage and branching stems of bright purple-blue flowers March to May. Some may be near white. 30cm.
The pale pink and white flowered form of this spring flowering hardy perennial pea relative. Low clumps of deep green foliage and branching stems of flowers March to May. Ordinary soil in sun. 30cm.
An elegant variegated form with an upright clump forming habit and fine foliage with white margins. Excellent and airy height for mixing into formal borders or naturalistic gardens. Good soil in sun. 1.5m.
AGM Compact clumps of rich green leaves and upright stems topped with dense, narrow, spikes of brown flowers in midsummer. At its best in autumn when all parts turn orange. 60cm. Good soil in sun.
AGM Not as dwarf as the name suggests! A classic form of catmint well suited to the traditional edging of large herbaceous borders or formal paths where a billowing cloud of lavender blue flowers all summer is required. Drained soil in sun. 60cm.
AGM Delightful white daisies flushed with rose-pink that deepen as they age, opening in sun. On dull days the grey-blue backs are still interesting! Bushy habit for well drained soil in a sheltered sunny spot. 30cm.
AGM Pure white daisies over greyish foliage making a low, rather sprawling plant for the front of the border. Hardy in a warm sunny spot with good drainage. 30cm high, 60cm spread.
TENDER AGM SCENTED One of the best known scented types with deeply divided leaves and heads of smallish pink flowers. The main reason for growing is the scent and flavour of the foliage. 40cm.
TENDER AGM Scented. Glowing coral pink flowers on a neat bushy plant. One of the first to flower with us. Makes a very pretty container plant. Protect from frost. 40cm.
Low clumps of greyish foliage and masses of over-the-top creamy caterpillar-like flowers from midsummer till the frosts. Well drained soil in sun. 45cm.
A delightful, hardy penstemon with masses of rich garnet red flowers and narrow leaves. Bushy habit flowering pretty much all summer and autumn. 45cm. Sun, drained soil.
Stunning lilac pink flowers in large panicles on strong, upright stems to 1.5m or even more! Self-supporting. Smaller flowers than typical border phlox but the better for it! Good soil in sun.

AGM Rich luxuriant red flowers of a good size on this fairly hardy shrubby sage with equally deep green leaves. Well drained soil in full sun for best results. 60cm.
AGM Brilliant glowing magenta pink flowers on a bushy plant to 60cm. Leafier than some types. For a well drained soil in full sun and a sheltered position.
AGM A stunning and well behaved Golden Rod with purple flushed foliage, best in full sun. Open, elegant heads of long narrow branches covered in yellow flowers in late summer. 1.2m. Average to good soil.
