AZALEA 'AUTUMN ENCORES'
Unlike traditional azaleas that flower only for a short period in
spring, Encore Azaleas have their peak flowering in autumn, then continue
to bloom through winter and into spring. They are free flowering and
have attractive evergreen foliage, will perform in sun or shade and
are cold and heat tolerant. Different varieties are Autumn Amethyst
(Conlee), Autumn Cheer (Conlef), Autumn Coral (Conled), Autumn Embers
(Conleb), Autumn Monarch (Conleo) and Autumn Royalty (Conlec). They
come in a range of growth habits and flower colours that make them
suited to varied uses. More varieties will follow in the years ahead.
All varieties are protected by Plant Breeder's Rights in Australia.
Vibrant purple single flowers. Dense,
spreading growth habit to 1m X 1m. Lustrous rough textured
green foliage in summer that gains purple colouration in the
winter. The most cold hardy of the Encore Azaleas.
Autumn Bravo
"Conlen"
Strong Orange/Red single flowers
up to 12mm across. The variety has strong dark green foliage
and will grow to 0.75m high and 1m across. The eye-catching
blooms add brilliant colour to any landscape.
Autumn Carnivale
"Conlet"
Brilliant mid-pink single flowers.
A dense spreading growth habit to 1m high and 1m wide. Heavy
summer flowering is typical. It is a real mid-summer traffic
stopper. Plant as mass planting or as a specimen.
Autumn Cheer
"Conlef"
Rose pink small single flowers. The
most compact of the Encore Azaleas, growing 60cm tall x 1m
wide. It’s growth habit and flowers resemble one of its parents,
the Kurume hybrid ‘Pink Cheer’, the flowers being slightly
larger and deeper in colour. Slow growing and particularly
suited to containers
Autumn Coral
"Conled"
Medium-sized coral to salmon pink
flowers with fuchsia flecking in the centre. In the U.S. it
has been an especially heavy bloomer throughout the summer
and autumn. Mounding growth habit to 1m x 1.2m
Autumn Embers
"Conleb"
Deep orange-red semi-double blooms,
especially prolific in autumn. Dense, spreading habit and
medium growth rate to 1m x 1.2m
Autumn Empress
"Conles"
Medium to Light Pink semi-double
blooms in massed bunches. A medium spreading bush to 0.8m
wide and 1m high. Dense dark green foliage makes “Empress”
ideal for planting around the foundation of a home or building.
Autumn Monarch
"Conleo"
A robust, tall variety to 1.25m x
1.25m, suitable as a background plant. Ruffled semi-double
blooms in a designer shade of dark orange-pink with reddish-purple
flecking offset by bright green foliage
Autumn Princess
"Roblea"
Semi-double medium sized pink flowers.
During the cold of winter the foliage may turn a vivid burgundy.
Growing to 1.2m high and 1m wide, the growth habit makes it
suitable for a specimen or as hedge planting.
Autumn Royalty
"Conlec"
Large single rich purple blooms and
large dark green foliage on rapid growing tall, upright plants
1.25m x 1.25m. Autumn Royalty is excellent for foundation
planting and as a background plant and it makes a fine hedge
Autumn Ruby
"Conler"
Ruby’s deep rose pink double
flowers contrast with emerald green foliage and are complemented
by an unusual red tinge on new stems. Ruby is an upright grower
reaching 1.2 metres, well suited to formal gardens, containers
and being clipped as hedging.
The story of Encore Azaleas
Robert E. Lee (no relation to the Civil War
general) worked in an azalea nursery when he was in high school,
but was employed as a nurse when he started experimenting with
a bit of breeding in his backyard. In 1982, visiting a friend
in midsummer, he noticed a tray of rooted cuttings of the relatively
rare Rhododendron oldhamii in flower. He started hybridising these
with traditional spring flowering varieties. This resulted in
7500 plants of different twice-blooming azaleas.
Ten years later Mr Lee turned to Flowerwood
Nursery in Alabama to help him select and commercialise the best,
and over five years they were narrowed down to six with outstanding
growth, flowering, foliage and colour characteristics. More varieties
followed, providing a greater selection of bloom colour and plant
size. Mr. Lee is still working to develop a wider array of Encore
Azalea varieties. Encore Azaleas have been grown and evaluated
in 21 public and botanic gardens across the U.S.
Small numbers of the first six varieties
were test marketed in the ‘fall’ of 1997, and larger
numbers released the following year. In the U.S. Flowerwood Nursery
has elevated these ‘azaleas that know no season’ out
of the traditional azalea market with special packaging and presentation,
brochures and point of sales material. Huge publicity about this
new class of plants from garden writers to Wall Street journalists
resulted in phenomenal sales.
Encore Azaleas flower on new wood, not
on old wood like traditional flowering azaleas. In the United
States spring flushes of flower are followed by a period of new
growth when new shoots appear. Then plants suddenly stop growing
and start setting buds. The ‘first act’ starts when
the buds begin blooming in mid- to late-summer. Flowering continues
and hits a high note in autumn, stopping only when temperatures
drop very low. In spring the flowering cycle starts again.
It remains to be seen exactly when the
different varieties stop and start flowering in different locations
in Australia. Edward Bunker has grown them for seven years at
Redlands, near Brisbane and says: “up here they flower all
year round except in the hottest months, and we have found the
same in Western Australia”.
Care Instructions
Encore Azaleas have similar planting, watering, and growing conditions
as traditional spring flowering azaleas. Plant into well-drained,
slightly acidic soil with average soil moisture. Will grow in
full sun or where they receive filtered light throughout the day,
or morning sun and afternoon shade.
Planting
Encore Azaleas are best planted in autumn when they will be most
widely available. Additional organic matter or peat moss worked
into the planting hole will prove beneficial, as will mulch. Water
Encore Azaleas well when first planted and keep the soil moist
until winter. New Encore Azaleas need regular watering until they
are established and in periods of drought.
Fertilising
Fertilise Encore Azaleas with slow release fertiliser or special
azalea food at recommended rates in spring. Do not fertilise in
autumn.
Pruning
Encore Azaleas require very little pruning to retain good form,
but can be pruned immediately after spring flowering for maximum
bud set. Spent flower removal is not necessary.
Uses
There is an Encore Azalea to suit most purposes and locations.
Plant Encore Azaleas in drifts or as specimens in gardens. Autumn
Monarch
is tall and robust and is suited to background planting; Autumn
Royalty
is an upright grower that is excellent for foundation planting
and for hedging. Autumn Coral
is a lower grower with a mounding habit. Autumn Cheer
is smaller and slow growing and ideal for container planting.
Autumn Amethyst
and Autumn Embers
have a dense, spreading habit. All grow and flower best on in
full sun or light shade. As cut flowers and foliage they will
last well over a week in floral arrangements.
