Benary’s Award Winning Program

rudbeckia hirta Denver DaiSY rudbeckia hirta Prairie Sun

as the world’s leading rudbeckia hirta breeder, Benary’s accomplishments have been rewarded with

numerous international awards. With a wide selection of heights, flower sizes, flower forms and colors,

no other program offers so much: High versatility, long blooming season, and superior heat tolerance.

rudbeckia from Benary are well known and proven performers.

numerous awards around the world have been given to this long day plant. High quality seed, easy

growing and versatility makes rudbeckia the perfect crop for growers, retailers and home gardeners.

Benary is proud to present maYa, the world’s first dwarf, double

flowering rudbeckia. The compact habit of maYa adds a new and

interesting form to the wide assortment of Benary’s rudbeckias.

Fully double flowers abound on this durable summer garden perfor-

mer. Strong stems hold the 4” (10 cm) bright yellow flowers upright.

Plantings of maYa resemble a bed of brightly colored tennis balls.

Fleuroselect awarded maYa the Gold medal for its outstanding field

performance. maYa also makes an excellent choice for a specimen

plant in containers or mixed combination pots.

Sonora has an extraordinary color combination with a large

mahogany ring on bright golden yellow petals. The very large flowers

5-6” (12-15 cm) and unique color of Sonora make it a great

impulse item at the retail level and an instant winner in the garden.

Sonora is a slightly larger plant than the Toto® series but offers

the same great variety of uses.

Denver DaiSY is a symbol of city-wide beautification for the historic

150th anniversary of the city of Denver. rudbeckia Denver DaiSY

was selected because of its extreme heat tolerance, its summer-long

flower power, and its ability to stand up under the extreme weather

variations in the mile-High city. Growers will love this rudbeckia

because of its high germination rates and high

percentage of usable seedlings. low

cultural inputs and short crop times

ensure that Denver DaiSY will

perform in a wide array of green-

house situations. 20-28”

(50-70 cm) tall, Denver DaiSY

is perfect for 1.0 gallon

production, or for large

landscape plantings.

Flower power is no understatement

for this beauty as large masses of gol-

den flowers adorned with rusty red rings

cover Denver DaiSY from late spring until first

frost. Strong, dense flower stems ensure that Denver DaiSY will not

flop or fall over in adverse weather conditions.

Denver DaiSY is the embodiment of the true pioneering spirit of the

american West. its raw beauty and ability to thrive in very

diverse and rugged areas makes it a perfect fit for the entire country.

Prairie Sun has very large 6.4” (16 cm) flowers with light yellow tips

on golden petals that encircle a green center. This variety looked so

bright and sunny in more than 70 Fleuroselect and all american Se-

lections field trials that judges ruled Prairie Sun a winner in north

america and europe. Prairie Sun’s unique color combination and

sturdy habit make this variety a winner in any garden location.

research on Benary’s rudbeckia varieties has shown how day

length manipulation can be utilized to achieve optimum plant

quality and minimize crop times:

Plants that receive 10 hours of light do not initiate flowering

but form rosettes.

Plants that receive 14 hours of light initiate flowers and have

stem lengths characteristic to the varieties natural height.

For growers looking to produce compact plants without the use

of plant growth regulators, light manipulation can be an effective

tool.

Rudbeckia hirtaTechnical Information

uses: annual

Plants for border, pot and container plants, cut flower production

exposure: Full sun

Garden height: 12-28” / 30-75 cm

Crop time: Plug crop: 288 tray 5-6 weeks; 128 tray 6-7 weeks. Flowering pots: 12-21

weeks depending on species and on the season. long days and high light will shorten

the production time.

Spring: Toto®, Sonora, maYa: ø 15 weeks, Denver Daisy: 14-18 weeks, Prairie

Sun, auTumn ColorS: 15- 21 weeks; Summer: Toto®, Sonora, maYa: 12-14

weeks, Denver DaiSY: 12-14 weeks, Prairie Sun, auTumn ColorS: 13-15

weeks

Seed form: Coated Seed

Sowing method: 1-2 seeds per plug, can be sown directly into final pot.

Germination:

Stage i and ii: 14-21 days at 68-72 °F / 20-22 °C,

Stage iii and iv: 10-14 days at 64-68 °F / 18-20 °C

requires light for germination. Before sowing treat substrate with fungicide. Cover

seed lightly with vermiculite after sowing. avoid direct sunlight by shading seeds after

sowing.

Sowing media: media with very low soluble salt levels; pH: 5.8-6.2. Keep soil slightly

moist but not wet.

Plug culture: media should be slightly less than saturated in Stage i. From Stage ii

reduce the soil moisture, but the plug should not dry out. Do not let soluble salt level

rise above 0,75 eC. The roots are sensitive to high salt levels in substrate. Start

fertilization at 50-75 ppm nitrogen in a well balanced formula. During Stage iii and

Stage iv fertilization levels can be increased to 150 ppm.

Growing on: if broad casting the seeds into open flats 3-4 weeks after germination

transplant 1 plant per cell into plug trays (1x1” / 3x3 cm) or per pot (2-3” / 6-8 cm)

and 5-6 weeks later transplant 1-3 plants into a larger pot (4-7” / 10-17 cm) or into

a container (3-5 l). Plant cut flowers (frost free) in 10-12” x 12-14” / 25-30 x 30-35 cm

space.

Media: use a well-drained, growing substrate with 20-30 % clay, 1-1,5 kg/m³

complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3-6 months), iron-chelate,

micronutrients, pH: 5.8-6.2. Field: loamy sandy to sandy humus soils with good

drainage and good nutrition levels. Standard fertilization: 80-100 g/m2 of a slow

release fertilizer.

Temperature: Grow at 64-68 °F / 18-20 °C. rudbeckia hirta needs warm

temperatures for the growth. Temperatures of 61 °F / 16 °C increase the cultivation

time by 3 weeks. Temperatures below 61 °F / 16 °C can be a cause for red coloring of

leaves. rudbeckia hirta does not tolerate frost.

Fertilization: moderate fertilization levels are required. Fertilize the crop weekly

with 100-150 ppm nitrogen (at 0 kg/m³ slow release fertilizer in substrate), using a

potassium balanced fertilizer (n: K2o-ratio: 1:1,5). avoid high ammonium and high

nitrogen levels. Prevent magnesium deficiency by applying magnesium sulphate

(0,05 %) 1-2 times and in case of iron deficiency (above pH 6.0) apply iron-chelate

1-2 times. Field: Take care of possible iron deficiency and apply iron-chelate1-2 times.

n min soil value: approximately 130 g n/m².

Light: long day plant. For flower initiation long days greater than 13 hr. are required.

We recommend somewhere between 14-16 hrs. for best results. Flowering initiation is

well timed 2 weeks (Toto®, Sonora and maYa) or 4 weeks (Denver DaiSY, Prairie

Sun and Denver DaiSY) after transplantation. Keep light level high, because high

light levels improve the plant quality and prevents excessive stem elongation. in winter

and in early spring additional assimilation light is required for pot plant and cut flower

production. night interruption is possible. a short day period can be used to control

the plant growth. 2-5 weeks after transplantation cultivate at short day (10 hr.)

conditions for 7-10 days for a compact plant growth. afterwards return to long day

conditions (14-16 hrs.) again. For Toto® in 4” / 9 cm pot extend the cultivation of short

days to 6-7 weeks until the end of cultivation.

Plant Growth Regulators: Seedlings are very responsive to sprays with B-nine

(daminozide) at 2,500-5,000 ppm. Bonzi (paclobutrazol) sprays can also be used at

10-20 ppm. light drenches at 1-2 ppm can be used on plants that are well established

in the final containers. Sumagic (uniconazol) can also be used. Due to differences in

locations produced trial applications are recommended. Contact a Benary

representative for exact recommendations.

Cultural hints: Keep humidity low and provide good ventilation. avoid over watering

and drought stress. Drought stress can be a cause for necrosis of leaf edges. avoid

over head irrigation and avoid late day watering to reduce the risk of Botrytis, especially

at cooler growing conditions.

The cultural recommendations are based on results from trials conducted under Central european conditions.Different conditions in other parts of the world may lead to deviations in results achieved.
