AZaleas can be an overwhelming maze of deciduous and evergreen species, cultivars,
and selections – with many designed for the cold northern regions as well as others
tailored towards greenhouse forcing. Finding one suitable to your [landscape](https://lifeandwork.blog/gardening-how-to-use-azaleas-in-your-landscaping/)
may prove a difficult challenge.

Breeding efforts by the University of Minnesota have resulted in an array of azalea
varieties suitable for our climate, boasting stunning colors and shapes.

## Climate Zones

When selecting azaleas for your [landscape](https://lifeandwork.blog/gardening-how-to-use-azaleas-in-your-landscaping/),
pay careful consideration to their appropriate climate zones. Zones indicate which
temperatures a variety will tolerate and selecting one that thrives in that zone
will give you longer-term enjoyment from it.

Cold-hardy azalea varieties specifically tailored for Zone 4 tend to be evergreen
varieties with an array of [bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
colors. Common examples are Northern Hi-Lights, Rosy Lights and Arctic Tern varieties
of cold hardy azaleas bred specifically for this zone; these plants can withstand
the bitter winter conditions found here.

Dawn’s Chorus Azalea (Rhododendron x Dawn’s Chorus) is an hardy hybrid rhododendron
with light pink flowers sporting deep yellow blotches that [grow](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
to approximately one meter tall, making it suitable for mass planting in shrub borders
and coastal Southern gardens. Furthermore, it is resistant to Rhizoctonia blight.

Evergreen azaleas require well-draining acidic soil, partial shade and regular watering.
Proper [pruning](https://lifeandwork.blog/pruning-azaleas/) to encourage new growth
and shape should also be undertaken, while mulch can help retain moisture and protect
roots during cold winter weather. Fertilization with balanced, slow release fertilizers
is also recommended to promote healthy growth and flowering; root cuttings should
be used if propagating these evergreen beauties; just snip a branch at least 6 inches
long then strip back all but one leaf from its lower inch for root propagation purposes.

## Kurume Azaleas

The Kurume Azalea is a low-[growing](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
evergreen shrub that [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
early to mid spring and reappears again throughout fall, hardy in zones 7 and 8,
and suitable for foundation plantings, gardens, woodland gardens or foundation plantings
in general. They can also be found hardy enough for use as woodland gardens. Hardy
in zones 7 and 8, Kurume azaleas can be used in foundation plantings, gardens or
woodland gardens and known for their vibrant pink or coral flowers with dark pink
centers that come together into single hose-in-hose arrangements although some cultivars
come with different flower shapes like ‘Rikyugonomi’* with stripes along its pale
throat; Mino double hose-in-hose form; and finally Yae with narrowly-shaped petals
that look like skirt-shaped petals! Hardy in zones 7 and 8.

Plants of this variety tend to be compact and create as much spread as height. Flowers
[bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/) profusely
while foliage remains evergreen for added interest and protection from cold temperatures.
Some popular cultivars of the R. kiusianum family include Coral Bells – with abundant
coral pink hose-in-hose flowers featuring darker pink centers and veins; Hinodegiri
with its vivid red [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/);
Pink Pearl which produces white [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/);
Hinodegiri hybrid with vivid red [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/);
Hino-Crimson developed by crossing R. kiusianum with other hardy hardy azalea species
for low [growing](https://lifeandwork.blog/gardening-how-to-grow-azaleas/) yet compact
growth twiggy low [growing](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
hybrid hybrid plants which also produces single forms such as ‘Hino-Crimson’ which
was developed through cross breeding; developed from breeding between R. Kiusianum
hybrid azalea species; produced hybridized offspring.

## Kaempferi Azaleas

Many reblooming varieties have been designed to [bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
again in late summer and fall even when temperatures rise, regardless of temperature
fluctuations. Although they prefer full sunlight, these perennials also thrive when
exposed to part shade or wooded areas that receive filtered sunlight. Acidic soil
with pH levels between 4.6-6 provides ideal [growing](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
conditions; soil testing provides accurate results.

Azalea flowers come in an assortment of colors, shapes, sizes and fragrances that
range from linear petal shapes to pointed petals with round [tips](https://lifeandwork.blog/common-mistakes-to-avoid-when-caring-for-azaleas/)
or even ruffled edges, varying depending on its species or variety of flower. Color
options may include white, pink and purple tones as well as funnel bell tubular 
or recurved varieties.

Evergreen azaleas are low-[growing](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
plants that tend to spread as wide as they [grow](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
tall. Some popular hybrid varieties that thrive in the South include Linwood and
Gable cultivars, Pennington and Harris hybrids, and Encore azaleas that [bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
again during autumn blooming seasons.

## Glenn Dale Hybrids

Benjamin Y. Morrison at the National Arboretum created these hybrids primarily to
meet winter hardiness criteria but are also quite decorative shrubs. Single flowers
and clusters of [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
were selected, as were varieties in colors ranging from white through pink, red 
and purple – as well as features like stripes, flecks or variegated margins on petals
or throats – creating low and spreading habits perfect for beds, borders or woodland
gardens.

“Dauntless” (Rhododendron ‘Rhododendron’ x ‘Amoenum’) is an exceptional Glenn Dale
hybrid variety, an extremely hardy repeat-bloomer with exceptional late spring [bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
color and exceptional [bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
durability. Its deep purplish red flowers feature scarlet eye zones complemented
by deeper red freckles for an eye-catching display of [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
that burst forth late.

This activity’s aim is to reestablish accurate, complete collections of 454 Glenn
Dale azaleas at Annmarie Garden as well as other arboreta and public gardens throughout
the country. By having such collections available, researchers will be able to undertake
numerous activities from identifying parent plants to comparing performance under
various climate conditions.

## Girard Azaleas

Girard azaleas are hardy perennial plants that excel in various climate zones and
feature an array of flower colors, such as double flowers that resist rebloom and
[disease](https://lifeandwork.blog/azalea-pests-and-diseases/). Girards make excellent
evergreen additions to mixed shrub or perennial plantings as well as foundation 
landscapes.

The Double Shot Watermeon variety features bright ‘watermelons pink’ flowers complemented
by darker pink throats for an eye-catching contrast. A compact plant, it works well
in most garden beds and containers and boasts attractive foliage to keep landscapes
looking good after flowers fade away.

“Raspberry Sundae” azalea is an attractive double-flowering reblooming variety with
beautiful raspberry-hued pink [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
that [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
twice each season – perfect for use as part of any flower bed or container arrangement!
It makes an eye-catching display.

Girard azaleas make excellent selections for gardens featuring dappled shade. Hardy
to five degrees Fahrenheit, they perform well as mixed border plants or foundation
plants in shaded mixed borders or cottage gardens.

## Indica Hybrids

Evergreen azaleas, which [bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
in spring and provide year-round color, make an excellent choice for warm climate
areas without winter chill. American breeders have developed hardy varieties that
flourish in local conditions while withstanding any [pest](https://lifeandwork.blog/azalea-pests-and-diseases/)
issues that arise.

Their efforts have resulted in an abundance of azalea varieties suitable for any
[landscape](https://lifeandwork.blog/gardening-how-to-use-azaleas-in-your-landscaping/)
or container, as well as flower beds or containers. From compact dwarfs to large
shrubs – with sizes and flower colors that span from compact dwarfs to large shrubs–
these azaleas make an impressive display in any setting.

Mississippi’s Encore and Re-[Bloom](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
hardy azalea series is among the most beloved hardy bloomers, designed to produce
continuous flower [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
throughout summer and fall and resistant to heat, humidity, drought, frost and [diseases](https://lifeandwork.blog/azalea-pests-and-diseases/)
like Phytophthora. However, other more recent azalea varieties also possess great
promise in our climate, including Girard hybrids bred specifically to withstand 
colder climates and Sherwood violet azaleas with abundant [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
and rich colors. These plants are perfect for massing or creating focal points in
shrub borders and perennial beds. Red Sunset produces large displays of coral pink
hose-in-hose flowers with darker pink centers and veins on low mounds; while Sherwood
Orchid produces vibrant violet [blooms](https://lifeandwork.blog/maximizing-azalea-blooms-tips-and-tricks/)
that contrast beautifully with delicate evergreen foliage.

## Satsuki Azaleas

Satsuki azaleas are ancient Japanese varieties that have been hybridized over 500
years, producing late season blooming flowers with single, hose-in-hose, semi-double
and single flowers ranging in hue from white through pink, yellowish pink, reddish
orange and exotic splotching to solids, stripes, flakes or lines of color on the
petals woven through solids, stripes or lines woven through them, with either round,
overlapped petals or narrow wide spaces between each petal that range in lobe size
from round or overlapped or narrow wide spaced and smooth edges flat to frilled 
edges.

These azaleas are easy to [grow](https://lifeandwork.blog/gardening-how-to-grow-azaleas/)
as they adapt well to various climate zones. Bunkwa (pink), Gumpo Pink, Higasa and
Shinnyo-no-Tsuki varieties are the most widely grown.

Bee vigilant in protecting your blooming satsukis from insects, as these flowers
are more vulnerable than their non-blooming counterparts to damage by insects. Also
be careful with water supply – your plants require steady but not too much at once
or they’ll get root-soaked! Overwatering could result in flower rot while under 
watering could halt progress on blooming; balance is key – particularly leading 
up to your show date! Nutrients are important but don’t go dumping nutrients like
you would onto fries – you’ll see bigger yield with less restraint.
