| Trees:
Cercidiphyllum
japonicum (Katsura
Tree)
This has got to be one of my favourite trees. In Autumn, delicious
candy floss aromas drift tantalisingly through the air from the
drying fallen leaves. It's a fast growing deciduous tree, growing
between 7 -15m high x spread (books will not agree!) with light
airy branches. The delicate heart shaped leaves are bluish-green
in colour with red stalks. New emerging leaves are bronze (spring
flowers are barely noticeable). Turns yellow, pink, and red in autumn,
colouring more dramatically in acid soils. Likes sun/partial shade.
Prefers moist humus- rich soils and this will probably dictate its
height (in Westonbirt arboretum the trees are 20m high). |

Sorbus
huphensis
(Rowan)
An elegant medium sized deciduous tree, originating from China. It
has striking white-blush pink berries on red stalks, which ripen from
September onwards and last well in to the winter. It's foliage is
divided and a bluish-green, and like other Rowans also turns good
autumnal colours. Clustered heads of white flowers appear in late
Spring.
Height & Spread: 6-8m. Sun and moisture retentive soil (is short
lived on shallow chalky soil).

| Climbers:
Clematis
tangutica 'Bill Mackenzie'
(Clematis)
Late
flowering clematis with finely divided leaves. Flowers are yellow
and bell-shaped appearing from July-October, fading to leave attractive
silvery silky bearded seedheads.This clematis looks good scrambling
into a tree. Likes moist to well drained soil. Sun/partial shade.
Height: 4 - 6m. |

|
| Parthenocissus
henryana
Related to the Virginia Creeper (Parthenocissus quinquefolia) -
this is a less vigorous variety. The decorative 5- fingered leaves
are variegated, providing year long interest. The leaves are mainly
green/ reddish purple, but with a subtle silver veining - particularly
prominent in shadier areas. The new leaves are a bronzey green turning
a rich red in autumn. This climber is self-clinging, but it may
take a couple of years before it climbs strongly. Height: 4-6m.
Fertile soil in sun/ partial shade/shade.

| Vitis
'Leon Millot'
(Grapes)
An
early ripening black grape. Deliciously sweet grapes, reminiscent
of large blackcurrants in size and flavour. Vigorous. Prune out
excessive grape bunches in June to allow the remainder to develop
and ripen properly. Also strategically remove vine leaves to allow
the sun to reach the ripening grapes, but leaving enough to still
provide nutrients to the vine. |

|
| Shrubs:
Abelia
x grandiflora (Abelia)
This graceful semi-evergreen usefully fills the late summer gap.
The fragrant trumpet shaped flowers are white/pink, flowering from
July to September. It needs a sheltered sunny aspect and well drained
soil. Prune in spring to remove twiggy growth if necessary. Height
spread 1.2 x 1.2m.

| Caryopteris
x clanodensis 'Heavenly
Blue' (Blue
spiraea)
A small sized upright deciduous shrub with low branches. The small-medium
sized foliage is greenish grey and aromatic. The 1cm wide flowers
are tubular and are a striking violet blue appearing from Sept-Oct.
Height: 1m x 1m spread. Thrives in dry soils (partic.chalk) and
hot sun. |

| Perennials:
Sedum 'Autumn Joy (Icelandic
Plant)
Succulent
grey-green leaves form attractive solid, rounded shapes which associate
well with grasses. The wide green flower heads appear in August,
transforming in September from a pale pink colour through to dusky
dark pink and eventually brown (seed heads) which last all winter
if you leave them. Sedums are wonderful structure plants for the
winter garden. Cut the dried stems and flowers off just before the
onset of spring to reveal the new green rosettes at the base. Bees
and butterflies love the flowers which provide valuable nectar in
the late season. Likes sun and will thrive in hot dry conditions.
Size: 60cmx 60cm.

Rudbeckia 'Goldsturm'
(Black
eyes Susan)
Golden
yellow daisy-like flowers with rich brown centres. Lasts for weeks
from July through to October, the yellow petals falling away to
leave striking dark buttons. Mid-green toothed leaves can sometimes
wilt in hot sun so make sure soil is moist enough. Plant in drifts.
Mine seem fairly resistant to slugs and snails here in Bristol but
no doubt opinions will differ! Likes sun/partial shade. Height 60cm
x 60cm spread.

| Miscanthus
'Malepartus' (Maiden Grass)
Dramatic
flower plumes fade from pink/reddish brown to silver which then
last all winter, giving you extra interest through the dormant months.
Grasses are great for introducing movement to garden, and as well
as catching the breeze they also catch the low autumn sun beautifully.This
diverse genus of grasses are excellent structure plants and a great
backdrop for late season flowers. Height 1.8m - 2.2m (with the flowers).
Spread: 1m. Dislikes very dry soils. Needs sun
