YELLOW HOUSELEEKS
The main attraction of houseleeks (Sempervivum) is their
colorful rosettes of leaves. These range from bright yellow
through various shades of green, gray, pink, purple, red, and
orange to almost black. The leaves may be dull or glossy, or
covered with soft down or longer hairs. Leaf shape can also
vary from short and succulent to long and tapering. The
rosettes are most striking in the spring and summer, but even
in the winter, many varieties remain attractively colored. It is
the endless range of different leaf shapes, shades, and
textures that make this group so interesting to enthusiasts.
Houseleeks do not like damp or shaded conditions, but thrive
in well-drained soil in full sun. They are ideal for pots or sink
gardens on a south-facing patio, or can be planted out in
rockeries or in the crevices of stone walls.

BULBS
Bulbous plants are found throughout the world in habitats as
diverse as woodland and scrub, meadows, river banks, the edges
of streams, and rocky hills and mountains. There are bulbs to
suit every garden site and design—from the tiny Iris danfordiae
for a rock garden, to daffodils and tulips in beds and borders,
and carpeting erythroniums or the statuesque Cardiocrinum
giganteum for a woodland garden. Most have a distinct flowering
season, yet with careful planning it is possible to extend or
enhance this period of interest. The majority bloom in spring or
early summer, producing splashes of color before many shrubs
and perennials reach their peak; others (such as snowdrops)
provide a late winter display, while colchicums, cyclamen, and
some crocuses will brighten a fall day.

GLADIOLI G. ‘Her Majesty’
[Grandiflorus Group]
Comprising about 180 species, with more than 10,000
hybrids and cultivars for garden cultivation, exhibiting, and
cutting, gladioli are prized for their showy spikes of usually
open, funnel-shaped flowers. Gladiolus hybrids are divided
into the Grandiflorus Group, with long, densely packed
flower spikes, categorized as miniature, small, medium-
sized, large, or giant, according to the width of the lowest
flowers, and the Primulinus and Nanus Groups, which have
loose spikes of small flowers. Plant gladioli in borders or
pots for late spring to early fall displays, and store corms
in a frost-free place over winter. In cold areas, grow them
by a sheltered, sunny wall; winter-flowering South African
gladioli require a cool greenhouse. For more information
see the Plant Dictionary.

ALSTROEMERIAS
Commonly known as the Peruvian lily, lily of the Incas,
or parrot lily, these South American tuberous perennials
are prized for their delicate, funnel-shaped blooms in
yellow, orange, pink, red, white, or purple, with decorative
markings in contrasting colors. They also have an
exceptionally long flowering season—from midsummer
to the first frosts—and make excellent cut flowers. Most
suppliers offer plants, rather than tubers, which are best
planted in spring after the late frosts in a sunny site and
free-draining soil, giving the roots time to establish before
winter. Although reasonably hardy, young plants are
vulnerable to cold, wet conditions—protect them in winter
with a thick mulch of well-rotted compost or manure.

LILIES L. ‘Casa Blanca’
L. martagon var. album
Lilies (Lilium species and cultivars) make elegant additions
to summer borders and containers. Their flamboyant flowers
range from nodding, upright, and trumpet-shaped forms to
turkscaps with recurved petals. The blooms are often spotted
with a darker or contrasting color, or have conspicuous
stamens. Many lilies have a powerful, sweet fragrance, most
notably the Oriental and Longiflorum hybrids, although a
few species are unpleasantly scented. The hybrids thrive
in sun and well-drained soil, and are available in a dazzling
array of colors, from white, pink, and red to shades of yellow
and orange. Lily species prefer partially shaded sites; some
also require acidic soil. Leave plants undisturbed once
established, as the bulbs are easily damaged. For more
information see the Plant Dictionary.

CANNAS
Grown as much for their dramatic foliage as for their
flamboyant flowers, cannas are ideal for lush, tropical
planting schemes, as an accent plant in a border, or as
a bold addition to container displays. Large paddle- or
broadly lance-shaped leaves are produced in a range of
colors, from green to dark maroon, and many are striped
or variegated, while the vibrant red, orange, or yellow
flowers bloom for many months from summer to early fall.
Plant these tender South American rhizomatic perennials
after the last frost in spring in fertile soil and full sun—they
require heat to flower well. In fall, cut down the stems and
leaves when frost blackens the foliage, and store the
rhizomes in a frost-free place over winter.

DAHLIAS
The wide spectrum of dahlia hybrids offers a bold display of color and form
from summer to the first frosts in fall. Dahlias flower prolifically—in the right
conditions a single plant may produce up to 100 blooms during a single season.
Flowers range in size from tiny 2in (5cm) pompons to huge exhibition blooms
more than 10in (25cm) across. They make beautiful border plants, the compact
types are ideal for containers, and all are good for cutting. In addition, no special
skills are required to grow them, except protecting the tubers from frost. Dahlias
are divided into groups according to the form of their flower heads. The most
commonly grown are illustrated below. Some dahlias have fimbriated (split
or notched) petals, and some (such as orchid-flowering dahlias) are available
in single and double forms.

TULIPS T. ‘White Dream’ t [Div. 3] T. ‘White Triumphator’ t T. ‘Purissima’ t [Div. 13]
Tulips are excellent for rock gardens, formal bedding, as [Div. 6]
elegant cut flowers, and for containers. Their bold flowers
are generally simple in outline and held upright, often with
bright, strong colors. Many of the species deserve to be
more widely grown alongside the large variety of hybrids
currently available. Tulipa is classified in 15 divisions, which
are described below.
Div. 1 Single early—cup-shaped, single flowers, often opening T. ‘Spring Green’ t T. turkestanica t

Div. 2 Double early—long-lasting, double flowers open wide in [Div. 8] [Div. 15]

Div. 3 Triumph—sturdy stems bear rather conical, single flowers, T. saxatilis Bakeri Groupt T. ‘Shirley’ t [Div. 3] T. ‘China Pink’ t
becoming more rounded, in mid- and late spring.
Div. 4 Darwin hybrids—large, single flowers are borne on strong [Div. 15] [Div. 6]
stems from mid- to late spring.
Div. 5 Single late—single flowers, usually with pointed petals, T. ‘Albert Heijn’ t [Div. 13] T. ‘Dreamland’ t [Div. 5]
are borne in late spring and very early summer.
Div. 6 Lily-flowered—strong stems bear narrow-waisted, single
flowers, with long, pointed, often reflexed petals, in late spring.
Div. 7 Fringed—flowers are similar to those in Div. 6, but have
fringed petals.
Div. 8 Viridiflora—variable, single flowers, with partly greenish
petals, are borne in late spring.
Div. 9 Rembrandt—flowers are similar to those in Div. 6, but have striped
or feathered patterns caused by virus, and are borne in late spring.
Div. 10 Parrot—bear large, variable, single flowers, with frilled or fringed
and usually twisted petals, in late spring.
Div. 11 Double late (peony-flowered)—usually bowl-shaped, double
flowers are borne in late spring.
Div. 12 Kaufmanniana hybrids—single flowers are usually bicolored, open
flat in sun, and are borne in early spring; leaves are often mottled or striped.
Div. 13 Fosteriana hybrids—large, single flowers open wide in the
sun from early to mid-spring. Leaves are often mottled or striped.
Div. 14 Greigii hybrids—large, single flowers are borne in mid- and
late spring. Mottled or striped leaves are often wavy-edged.
Div. 15 Miscellaneous—a diverse category of other species and their
cultivars and hybrids. Flowers are borne in spring and early summer.
