 2. Lychnis flos cuculi

Lychnis flos cuculi on The Cotswold Garden

3. Tiarella

Tiarella on Defying Gravity School Garden Challenge at RHS Malvern Spring
With its understated white and pink spires, Tiarella softened beds and borders in most of the Show and School Challenge Gardens at the Festival. It was most effectively used as underplanting, where the deeply-lobed leaves reflect the palmate foliage of maples.
 
  • Position: partial or deep shade
  • Soil: cool, moist, humus-rich soil
  • Rate of growth: fast-growing
  • Flowering period: May to July

  • Position: full sun
  • Soil: light, well-drained garden soil
  • Rate of growth: average to fast-growing
  • Flowering period: March to July

5. Aquilegias

Aquilegias on The Grand Appeal Garden
While nearly all of the gardens at RHS Malvern Spring had aquilegiasthey played very different roles. Some brought deep purple colour, as seen on It Doesn’t have to Cost the Earth. On The Laskett Garden, they were largely spent, to represent the different stages of life in a garden. The Grand Appeal Garden used two cultivars of white Aquilegia  ‘White Barlow’ and ‘Green Apples’ – to bring a soft serenity to the garden.
 
  • Position: Full sun or partial shade
  • Soil: Fertile, moist, well-drained soil
  • Rate of growth: Average
  • Flowering period: May to June
  • Hardiness: Fully hardy

6. Hostas

Hosta 'Halcyon' on The Laskett Garden
The large leaves of this show garden favourite gave a tropical feel to The Ugly Bug Ball School Challenge Garden. Variegated and vibrant green forms brought light to shady under planting in Concete 2.0 and Macmillan Legacy Gardens, while The Laskett Garden showed off their impressive ‘Halcyon’ specimens in raised containers, flanking the central path.
 
  • Position: partial or full shade
  • Soil: fertile, moist, well-drained soil
  • Rate of growth: average to fast-growing

  • Rate of growth: average
  • Flowering period: June to July

8. Myosotis sylvatica
