growth and delay flowering. For active growth,
keep day temperatures around 80° F and night
temperatures above 60° F. Lower temperatures
can be used but plants will be slower.
Keep light levels at 5,000 to 7,000
With the Sun Parasol family launch, Suntory Flowers revolutionized the
Mandevilla market for growers and gardeners. These plants are the perfect
solution to create a lush tropical paradise summer after summer.
20 Years
of Planting Paradise
Suntory Flowers has developed many categories in the Sun Parasol lineup,
including unique shrub forms perfect for container gardens and landscape
plantings, large traditional climbing varieties that will cover trellises in the
garden, and fun trailing varieties, perfect for hanging baskets.
footcandles. Buds are initiated with 10- to
11-hour days. Supplemental lighting will be
required in the North for spring sales windows.
High pressure sodium lights or LED lights that
increase day length and light intensity should
be turned on in January and February to
enhance growth and flower development.
The Pretty Group needs full light in the
spring but benefits from partial shade in the
summer. Flower buds can abort if exposed to
too much light.

Media, nutrition and irrigation:
Most well-drained commercial soil mixes
should be satisfactory. Maintain a pH of 5.8
to 6.2 and a fertilizer rate of 100 to 200 ppm
NPK. For large containers, add a controlled
release fertilizer at one fourth the rate.
An EC of 2500 to 3000 is the optimum range.
Keep plants on the dry side when maturing.

TRANSPLANTING
Northern
growers should continue to grow
Sun Parasol plants in the greenhouse. Southern
growers can move plants outside to take
advantage of warm summer temperatures.
Light intensity and temperature are the greatest
influencers on timing for spring sales.
In states with lower humidity, like California
and Arizona, light shade is beneficial to reduce
high transpiration through leaves. In states with
high humidity, like Florida and Texas, plants can
remain in full sun.
Late summer and fall are build-up times
for mandevillas. Northern growers should
keep plants in a greenhouse that maintains
temperatures of 40° F or higher. In the South,
plants can stay outside but frost protection is
recommended to avoid leaf drop. If extreme or
abnormal winter weather is forecasted, make
a plan to move crops inside a greenhouse to
reduce loss counts.

The original Sun Parasol varieties are an interspecific
hybrid between traditional Mandevilla and
Dipladenia varieties. This creates a plant with a
full shrubby habit and a lot of branching, giving us
far more blooms and the large, open flower style
of Mandevilla for a genuinely upscale display.
These are also outstanding garden performers in
containers and the ground with very little
maintenance for summer-long color.
growth. It is beneficial in small containers or to
keep vines better attached to supports. Some
growers prefer not to pinch because it can cause
scarring.
Heavy watering can produce growth with long
internodes. Reducing irrigation frequency can
reduce internode length. Again, mandevilla does
not like to be left too wet or over watered.
To keep side shoots shorter, you can use a

tank mix of Cycocel at 600 ppm and B-Nine at
800 ppm. Apply only as a spray. In general,
the highest Cycocel rate that does not cause
excessive leaf yellowing can be used, and then
B-Nine rate can be raised or lowered to adjust
the strength of the tank mix.

Giant
These traditional trellis varieties are favorites in the garden for creating
a lush tropical display full of vivid color. These classic vining types have
enormous flowers and larger leaves. Natural climbers thrive in heat and
full sun for dramatic displays all summer. Gardeners love Red Emperor
for its intense deep red color. Giant Dark Pink's blooms start out light
and deepen with age, creating a tonal effect. Giant Marbled Crimson has
bright white variegated foliage, unique in this class.
Watering in the morning helps. Prevent fusarium
and botrytis by keeping plants dry in the winter.
If plants are held cool and wet overnight, foliage
can become necrotic.
Pests to monitor include aphids, thrips,
spider mites, whiteflies and mealy bugs.

Pretty
The Pretty varieties, like the Giants, are quick to cover walls and trellises with summer-long
color. This pair is well recognized with a smaller, shiny, dark green leaf and an enormous amount
of smaller blooms. Pretty varieties are also the most cold-tolerant lineup, so they are very popular
with northern growers and gardeners.
