The spectacular flowering of the evergreen azaleas is nearly over and the stage is left to the late rhododendrons and deciduous azaleas, many of which are fragrant.
The huge prickly leaves of the Gunnera manicata conceal its stout flowering spikes, and contrast with delicate fern fronds and the ribbed, glaucous leaves of hostas. Here and elsewhere bordering the streams, you will find Primula japonica, a candelabra type, in its red, white and magenta forms; lilac-purple Primula beesiana and fragrant yellow Primula florindae. Several iris species are also in flower, including Iris pseudoacorus, our native yellow flag. The Day Lilly, Hemerocallis hyperion, with its lemon-yellow flowers also grows in the beds beside the stream. The new island bed looks stunning at this time of year with the fern Dryopteris erythrosora showing coppery pink young fronds and the Swamp Honeysuckle, Rhododendron viscosum, bearing its spicily fragrant, white flowers.
The Birthday Mound
Digitalis purpurea 'Alba', the "White foxglove" is naturalised throughout this area which was planted in 2003 to celebrate Isabella's 50th anniversary. This european native produces spikes of white bell-shaped flowers with a maroon spotted throat from a rosette of rich green leaves.
Along the Main Stream look out for Galax urceolata, a clump forming perennial with large, round, leathery, mid-green leaves which turn bronze in autumn. It has dense spikes of small, white flowers.
Look out for Neillia thibetica which grows opposite the Beauty Bush, Kolkwitzia amabilis, with its profusion of small foxglove-like pink flowers. This medium sized shrub has slender terminal racemes of pink, tubular flowers. Cornus kousa chinensis also grows in Wilson's Glade, its numerous flowers which have conspicuous white bracts poised on slender stalks cover its spreading branches in June.
Flowering trees and shrubs worth seeking out
- Liriodendron tulipifera, the "Tulip Tree" stands at the Broomfield Hill Top Gate and other locations within the garden. As well as having odd shaped leaves which turn butter yellow in autumn. It has peculiar yellow-green flowers, with internal orange markings, which appear in June and are tulip-shaped.
- Calycanthus floridus, "Carolina Allspice" grows in the "V between the Streams", this Californian species produces aromatic red-brown flowers throughout the summer months.
- Stewartia pseudocamellia, grows by the path above the Heather Garden. This deciduous tree bears five petalled white flowers with orange-yellow centres.
- Kalmia latifolia, which can be found where the path to the Still Pond crosses the Main Stream. It is an evergreen shrub, whose intricate pink flowers, when in bud, resemble 'Iced Gem' biscuits.
- Styrax japonicus, the "Snowbell Tree", has a profusion of small white bell-shaped flowers dangling below its slender branches. One of several can be found in the bay to the east of Thompsons Lawn.
- Azaleodendron 'Govenianum' has trusses of funnel shaped lilac-purple flowers which are very fragrant. A group grows by the sandy path leading to the west of the Garden from the behind the iron '1831' sign.
