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.
AGM Very similar to the well known A. sphaerocephalon but this has light yellow flowers. Well behaved and very pretty mixed with grasses. Drained soil in sun. 60cm.
Amazing white spathes with pink candy stripes inside appear slightly before the leaves in late spring. Big rounded trifoliate leaves make an attractive feature later. Good soil that never sits wet in shade. Flowers to 30cm, leaves to 75cm.
One of the best in the recent RHS trials with a compact habit, good purple-red winter foliage and lots of clear pink flowers in spring. Good for a sunny drained position. 40cm.
AGM Neat clumps of glossy green foliage and short spikes of bright reddish-purple flowers in summer. Compact plants for the front of the border. Average soil in sun. 25cm.
AGM The best form of this species in our opinion! Light grey-blue-pink flowers on tall strong stems in summer to 1.8m. Best in good soil in sun or light shade.
AGM Probably the largest flowered Crocosmia, easily to 8cm across when happy. Open, narrow petalled flowers in a clear orange with a yellow throat. 80cm. Sun.
AGM Stunning white flowered forms of the hardiest autumn flowering cyclamen. Triangular leaves marbled with silver. Best in sunny places under woody plants. 10cm.
AGM Near white flowers soon flush pink then near purple on dark burgundy stems over clumps of striking leaves the same colour. Full sun, drained soil. 60cm.
AGM A elegant species with slender bright reddish pink flowers with purple corollas and red filaments. Smallish but broad leaves try to be evergreen. Borderline hardy - drained soil in a sheltered position, light shade. 60cm?
AGM Striking milky white flowers in short branching spikes above fresh green foliage on this clump former. Sterile so no self-seeding. Ordinary soil in sun or part shade.
AGM An unusual form with many bright rosy pink flowers with reddish veins on a compact plant to 20cm. For drained soil in sun, ideal for the front of a border.
AGM Glorious shining white flowers over clumps of grey foliage from midwinter throughout spring. Well drained soil in full sun. Even better in a porch or cold greenhouse. 15cm.
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.
A good doer with upright columns of fresh green foliage topped with metallic reddish flowers that fade to a golden buff. September through winter. 1.8m. Full sun in reasonable soil.
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.
