Work is progressing on a new garden at RHS Rosemoor in Devon. The Cool Garden
, which will replace the former Spiral Garden, is expected to open in summer 2019.
The many garden rooms within the formal gardens at Rosemoor were always meant to change with time – these areas are ideal to showcase different themes and designs and this is one of the last to have a makeover.
The updated planting will continue the cool, pastel tints of the Spiral Garden to provide a contrasting partner to the fiery hues of the adjacent Hot Garden
Garden designer and Rosemoor advisor Jo Thompson has created the concept, which will be
Rosemoor’s first model garden with a water focus, featuring rills running through the garden to a teardrop-shaped pond.
‘We wanted to show how landscapes can help deal with high volumes of rainfall, which we obviously have in Devon, so the lower section of the garden will be a permeable resin-bound gravel to help reduce surface runoff,’ says Curator Jonathan Webster.
Around half of the plants from the old Spiral Garden will be reused in the new garden, with new cultivars added in order to broaden Rosemoor’s collection as a whole. Flower colour will be predominantly blue, white and pale yellow, complemented by grey foliage, which will be used across all beds.
Visitors will find irises by the water, while birches will add height and echo the woodland and adjacent Winter Garden. Grasses will give movement and texture, and mass herbaceous plantings will give impact, along with Philadelphus
and roses for scent.
In the top corners will be groups of repeat-flowering shrub roses, which give an extra dimension to the plantings during the summer months, and within the bottom corners the rose element will be Rosa rugosa ‘Alba’.
Key plants planted in multiple groups will help knit the garden together including, among others, Caryopteris incana
, Echinops bannaticus
'Taplow Blue' and Geranium 'Orion'.
Bulbs in the central beds will include Allium
‘White Cloud’ and Galtonia candicans
while the corner beds will feature Camassia leichtlinii subsp. leichtlinii.
‘Elsewhere in the garden we have natural watercourses that are planted in a far less formal way, so it is great to be able to further increase the diversity of design here at Rosemoor to help inspire our visitors and members as to what they could do at home,’ says Jonathan.
The new Cool Garden is expected to open in summer 2019.
