BLUE WISTERIA
Wisterias are large, vigorous, deciduous climbers that
flower from late spring to early summer, producing pendent
racemes, 18in (45cm) long or more, of scented, pealike
flowers. These open in shades of white, through pale
lilac-blue, to dark purple, and are sweetly scented. Often
seen growing over the front of buildings, wisterias need
strong support as they become heavy with age, and their
roots may damage building foundations. They prefer fertile,
moist, well-drained soil in full sun or partial shade. Unless
the soil is very poor, don’t fertilize them, as this encourages
excess growth. Choosing wisteria can be confusing because
many varieties are commonly mislabeled.

PERENNIALS
One of the largest plant groups, perennials offer seasonal color,
fragrance, form, and texture, with a wealth of plants to suit
every size and style of garden. They are traditionally grown
in herbaceous borders, using a wall or hedge as the backdrop
for the main summer display, but since most gardens are not
large enough for long borders solely devoted to perennials, they
are usually grown in mixed borders, together with shrubs,
annuals, biennials, and bulbs that extend the seasons of interest.
Although some perennials are evergreen, most die back in fall
and emerge again in spring. While this can leave borders bare in
winter, the seedheads and dried stems of some perennials,
including rudbeckias, echinops, and hylotelephiums,
provide a beautiful display when others have disappeared.

Many tall perennials, such as delphiniums and achilleas, become top-heavy and

DELPHINIUMS
Delphiniums make a bold statement in summer gardens,
with their elegant, showy spires of single or double flowers.
Their classic color is blue, but hybrids are now available in
a broad range of colors, from white and pastel shades of
pink and lilac, to rich mauves, violet-purples, and new red
selections. Grow tall delphiniums in a mixed border or island
bed, and dwarf types in a rock garden. Plants thrive in full
sun and well-drained soil and, apart from dwarf species and
cultivars, all require staking securely to support their heavy
flower spikes. In growth, water all plants freely, applying
a balanced liquid fertilizer every 2–3 weeks. Deadhead by
cutting spent flower spikes back to small, flowering
sideshoots. Protect plants from slugs and snails.

HIMALAYAN POPPIES
With delicate flowers in a wide range
of colors, including beautiful shades
of sky blue, Meconopsis (Himalayan
poppies) are striking garden plants.
Some also have attractive rosettes of
foliage that develop slowly before the
first flowers appear. Many are suited to
moist, woodland conditions in light or
partial shade, and acidic, well-drained
soil; others are best treated as alpines in
raised beds or troughs. All prefer cooler
conditions. Most of the big blue poppy
cultivars are sterile and very long-lived.
Other Meconopsis are monocarpic
perennials, living for a few years before
flowering, setting seed, and then dying.

IRISES I. ‘Ringo’ t [bearded] I. ensata ‘Rose Queen’ t I. japonica t [Evansia]
Few other perennials show such diversity of flower color [bearded]
as irises; and you will find one for almost every position in
the garden. They have a long flowering season, the earliest
appearing in the first months of the year, the latest in early
fall. Their flowers often have “beards” (short hairs) or crests
that add to their appeal, while a few are grown for their
foliage or seed heads. The genus is classified into many
divisions. Of these, the easiest to grow are the bearded,
crested, and Xiphium irises. Siberian and Japanese types
are ideal for bog gardens or watersides, but they will tolerate
drier sites. Juno, Oncocyclus and Regelia irises are more
difficult to grow, though their beautiful flowers are worth
the effort. For more information, see the Plant Dictionary.

AQUILEGIAS
Commonly known as columbines, Aquilegia are ideal cottage
garden plants, well suited to growing in borders, rock
gardens, and as fillers between summer-flowering shrubs.
Most are graceful, elegant plants with divided basal foliage
topped in late spring and summer by a succession of
delicate, bell-shaped, usually spurred flowers, although
some have rounded double blooms. They vary in color
from light and dark blue, purple, almost black, dark red,
and pink, to orange, yellow, and white; many are bicolored.
Aquilegia thrive in moist but well-drained soil, and full sun or
dappled shade. They are normally raised from seed, which is
freely produced, and once established, they tend to self-seed,
although most do not come true to type.

PEONIES P. lactiflora ‘Pillow Talk’

Peonies (Paeonia species and cultivars) are valued for
their showy blooms, filling borders with whites, pinks, P. x suffruticosa ‘Hana-kisoi’

Flowers include single, double, or anemone forms (with t [tree peony]
broad, outer petals and a mass of petaloids in the center);
some are scented. They may need support when in full
bloom and make good cut flowers. The foliage is striking,
too, often tinged bronze when young and rich red in fall.
As well as many attractive species and a wide range of
herbaceous hybrids, there are several tree peonies
(cultivars of P. x suffruticosa), and intersectional hybrids,
which are crosses between the latter two. Peonies prefer
sun, but will tolerate light shade, and need rich, well-
drained soil. These long-lived plants resent transplanting
and are best left undisturbed.

PERSICARIA P. microcephala ‘Red Dragon’
The popularity of Persicaria have
increased in recent years, as gardeners
realize the value of these plants in a
range of different situations. Most
flower profusely for many weeks during
summer, while those with handsome
foliage are prized for the beauty of their
leaves rather than their blooms. Taller
selections are usually self-supporting,
while lower growing types will form
useful, weed-suppressing ground cover.
Grow Persicaria in moist soil in sun or
partial shade; P. bistorta tolerates drier
soil. A word of warning: some, such as
P. microcephala ‘Red Dragon’, can be
invasive and will need to be controlled.

PENSTEMONS
Valued for their racemes of foxglovelike flowers,
Penstemons are elegant and reliable border perennials.
Numerous cultivars are available, in colors that include
white, pale and dark pink, warm cherry-red, clear blue,
and shades of purple. Many flowers have contrasting white
throats or are streaked with other colors. Penstemons flower
prolifically in summer and the display can be prolonged,
provided the plants are regularly deadheaded. Some taller
cultivars may need staking. All types thrive in well-drained
soil, preferably in full sun. Some are not fully hardy, and
where winters are severe, plants should be overwintered in
a cold frame. Plants are more likely to survive frost if grown
in a sheltered spot and mulched in fall. Penstemons are simple
to propagate and can easily be raised as cuttings.

ORIENTAL POPPIES
The large-flowered selections of
Papaver orientale are stars of the

petals, borne in profusion above
mounds of hairy foliage. Numerous
selections are available, with flowers
in pastel shades of white, pink, and
plum-purple, or red and orange for
dramatic hot-hued borders. Large
round seed heads keep the display
going for a few more weeks after the
flowers have faded. Poppies thrive in
fertile soil in full sun, but plants die
down in midsummer; ensure that
other later performers fill the gaps.

DAYLILIES H. ‘Neyron Rose’
Although they belong to the lily family (Liliaceae), daylilies
(Hemerocallis) are not true lilies; their common name comes
from their lilylike flowers that last just one day, but appear
in succession for many weeks in summer. Daylilies range in
size from compact plants that grow 12–15in (30–38cm) tall,
to large plants that may reach 5ft (1.5m). They form clumps
of arching, strappy foliage, and flower colors range from
creamy-white, yellow, orange, red, pink, and purple to
almost black; some also have bands of contrasting colors
on the petals. The flower forms are classified as single,
double, or spider and some are fragrant. They thrive in
most soils, except waterlogged, in sun or shade, but
flower best when in the sun for at least part of the day.

PINK YARROW
Stalwarts of the summer garden, yarrow (Achillea) are
easy-to-grow perennials for sunny sites and well-drained
soils. Taller types are best planted toward the back of
herbaceous borders, while shorter forms associate well
with grasses in naturalistic planting schemes. Both selections
also look at home in mixed beds and gravel gardens. Most
have flattened flower heads, creating a horizontal plane that
contrasts well with vertical flower spikes. Available in a range
of colors, including white, yellow, pink, peach, and red, the
flowers change color as they age, creating a two-tone effect.
Many make good cut flowers; some can also be dried.

MICHAELMAS DAISIES
Invaluable border plants, Michaelmas daisies (comprising
Aster and Symphyotrichum, mostly S. novae-angliae and
S. novi-belgii species and cultivars) flower later than many
other perennials and continue the display until late fall. The
smaller-flowered species and selections associate well with
grasses and naturalistic planting schemes, while the larger
flowers are excellent for cutting. The daisylike, single or
double flowers range in color from white, pink, and red
to purple and blue. Michaelmas daisies thrive in sun or partial
shade and well-drained soil, and tall cultivars may need
staking. For large flowers, pinch out weaker shoots in spring;
for bushier plants with a greater number of smaller flowers,
pinch out the top 1–2in (2.5–5cm) of all shoots in late spring.

SALVIAS S. pratensis ‘Pink Delight’ S. x sylvestris ‘Mainacht’ S. nemorosa ‘Caradonna’
Hardy perennial salvias are useful
plants, many flowering profusely in late
summer and lasting well into fall. The
genus is quite diverse, with plants in
a range of sizes and flower colors,
including white, true blue, purple, pink,
and red. A few, such as S. argentea, are
also grown for their foliage, which in
many species is aromatic. Salvias thrive
in hot, sunny sites and free-draining
soil, and grow quickly, many developing
into shrublike plants within a season. To
ensure they survive cold winters, in fall
spread a thick mulch over the plants to
protect the roots.
