SECTION ALEURITIA 

This section contains small, often farinose, plants
which inhabit marshes or stream beds. They are
excellent subjects for troughs, planters, or shady
rock garden. The flowers may be lavender, pink, rose
or white. Many have a brief life cycle and can be
propagated easily by division or seed.

ARMERINA 

These species are without farina, usually small,
moisture and shade-loving. In nature, they grow in
meadows and bogs and will not tolerate drought
conditions. They can be propagated best by fresh seed
and division.

AUGANTHUS 

These rhizomatous, evergreen plants often have lobed
leaves with distinct petioles. The most common, P.
sinensis, is not hardy in winter frost areas. Primula
sinensis has dinstinctive, bonnet-shaped calyces.

AURICULA 

This section contains leathery-leaved, evergreen
alpine plants which, when not in bloom, are often
mistaken for succulents. Many are commonly grown in a
moist section of the rock garden. Some of the
exhibition auricula hybrids have been cherished by
gardeners for centuries. Propagation is by offsets or
seed.

CAPITATAE 

As the name implies, the flowers are contained in
dense head-like umbels. Plant parts are generally
farinose and hairy. White farina dusting the dark
purple flowers adds to the charm of these
late-flowering plants. Plants need partial shade with
adequate summer moisture and good drainage. Propagate
by fresh seed or division after flowering.

CORTUSOIDES 

These woodland species are deciduous, or rarely
evergreen, with soft, hairy leaves. The stems hold
umbels of white, pink or purple flowers well above the
leaves. Some species, like P. sieboldii , can be found
in a wide variety of flower colors and forms. Easy to
cultivate, they can be propagated by seed or division
as the leaves emerge in the spring.

CRYSTALLOPHLOMIS 

These tall, stately plants inhabit wet meadows, screes
or bogs. The species are deciduous, forming large
winter resting buds. They do best in a cool summer
climate, but the vigorous root system needs good
drainage during wet winter months. Propagate by seed
or division.

CUNEIFOLIA 

This section contains small, alpine tundra plants with
glossy green, dentate leaves. Flowers, typically
white, pink or rose, are held above the leaf rosettes
in generous umbels. They are best grown in partial
shade in pots or troughs in a well drained, peaty soil
mix, with some protection against winter wet.
Propagate by seed, division or cuttings.

DENTICULATA 

This is the "Drumstick Primula" section. These robust
perennials send up tight, spherical flower heads early
in the spring. Flowering often occurs just as the
long, leathery leaves are emerging from a winter
resting bud. Easy to cultivate, most species can
thrive in any soil condition, provided they do not dry
out in the summer. Plants can be propagated by seed,
division or root cuttings.

MONOCARPICAE 

As the name implies, these species often bloom only
once. The most common, P. malacoides , is a popular
plant for a cool greenhouse or conservatory. Not hardy
in cold climates, they are often used as an early
blooming, bedding plant in warmer areas. The hairy
leaves with farina on the underside combined with
clouds of purple, rose, lavender, pink or white
flowers make an attractive container plant. They can
be easily grown from seed.

MUSCARIOIDES 

These short-lived perennials contain some of the most
striking and unusual primulas. In nature, they are
found in wet meadows as the snow recedes. All have
deciduous basal leaves and spikes or dense heads of
small, usually fragrant, flowers. P. vialii resembles
a red-hot poker with scarlet calyces and blue violet
flowers giving the appearance of a blue poker with a
red tip. It flowers later than most primulas. All
species are propagated from seed or division.

OREOPHLOMIS 

These small to medium-sized perennials bloom very
early in the spring. Above smooth-textured, toothed
leaves rises a stalk of bright rose pink, yellow-eyed
flowers. The leaves continue to elongate as the
blooming season progresses. The most commonly grown
species, P. rosea , is best grown in a rich, wet soil
that does not dry out in the summer. Propagation is by
division as it comes into spring growth or by seed.

PRIMULA 

The best known of the primula sections, this one
includes the common primrose (P. vulgaris ), the
cowslip (P. veris ) and the oxlip (P. elatior ) as
well as many horticulturally important hybrids. Easy
to grow in fertile, water retentive soil, they can be
free- flowering and long lived. Most are winter hardy,
by should not be allowed to dry out in the summer.
Propagation is by division after flowering or by seed.

PROLIFERAE & HYBRIDS 

Earlier named the Candelabra Section, the flowers
appear in whorls on tall stalks. These robust
perennials are easy to grow in a moist, fertile soil
that does not dry out. They make excellent bog or
stream side plantings that flower in May and June. The
flowers are very attractive to hummingbirds and
butterflies. Depending on the species, the flowers can
be found in almost every color except blue.
Propagation is by division as they come into growth or
by seed.

SIKKIMENSIS 

Small to very robust, deciduous perennials are found
in this Himalayan section. Their natural habitat is a
monsoon climate in bogs, alpine meadows or along
streamsides. The largest and most commonly grown
species (P. florindae, P. sikkimensis, P. alpicola )
are excellent choices for the bog garden or along
streams. The yellow, fragrant, farinose flowers of P.
florindae and P. sikkimensis are held in umbels on
stems from 12 to 30 inches tall making a striking
statement in a semi-shady location. Propagate by
division or seed.

SOLDANELLOIDES 

With flowers like a very fragrant soldanella, these
plants are extremely beautiful, but somewhat difficult
to grow. The bell- shaped white or lavender flowers
are very large in comparison to the small stature of
the plant. They are usually grown in containers with a
humusy, but well-drained soil mix that is watered
regularly in the summer, but kept almost dry in the
winter. The containers should be placed in a cool,
semi-shady location during the summer. They are best
propagated by seed.

SPHONDYLIA

The species in this section are not hardy in colder
climates. However, they make excellent container
plants in a cool room or conservatory. The bright
yellow flowers appear from Decenber to April above
leaves often covered with white meal. A peat-based
soil should be kept rather dry during the winter and
more moist during the summer months. Hybridization of
two of these species gave rise to the popular P. x
kewensis . Propagation is primarily by seed. 

verticillata 


SREDINSKYA 

Some experts list this monospecific group as a
separate genus; one source classes it as a subgenus
and section of primula. Primula grandis has pale
yellow, nodding, urn-shaped flowers with a style that
extends beyond the petals. An umbel containing large
numbers of flowers tops a sturdy stalk about 30 inches
tall. The basal leaves are rounded with a heart-shaped
base. These plants require adequate moisture,
nutrients and a cool, partially shady location.
Propagation is primarily by seed.
