Description

Details

Germination
Approximate seed count (raw): 1,820-2,380 S./oz. (65-85 S./g)
Key flowering facts:
• Sparkle Gaura is a first year-flowering perennial.
• Photoperiod response: a facultative long-day plant and requires 13 hours or longer daylength for uniform and faster flowering.
• Vernalization: Not required. May result in earlier flowering following a minimum of six weeks cold treatment.
• Flower timing:
- Sown in January for Spring production, will flower naturally in early May to early June dependent on temperature.
- Sown in July to early September for overwinter production, will flower mid to late May of the following year.

Media
Use a well-drained, disease-free, soilless media with a pH of 5.5 to 6.2 and a medium initial nutrient charge (EC 0.75 mmhos/cm).

Sowing
Sow 1 seed per cell to 288-plug tray. Covering seed with vermiculite is recommended.

Stage 1 – Germination takes 5 to 6 days.
Soil temperature: 65 to 68°F (18 to 20°C)
Light: not required.
Moisture: Keep soil wet (level 4) during Stage 1.
Humidity: Maintain 95%+ relative humidity (RH) until radicles emerge.

Plug Production
Stage 2
Soil temperature: 66 to 70°F (19 to 21°C)
Light: Up to 2,500 f.c. (26,900 Lux)

Moisture: Reduce soil moisture slightly (level 3 to 4) to allow the roots to penetrate into the media.
Fertilizer: Apply fertilizer at rate 1 (less than 100 ppm N/less than 0.7 mS/cm EC) from nitrate-form fertilizers with low phosphorous.

Stage 3
Soil temperature: 65 to 67°F (18 to 19°C)
Light: Up to 2,500 f.c. (26,900 Lux)
Moisture: Allow media to dry further until the surface becomes light brown (level 2) before watering. Keep the moisture to wet-dry cycle (moisture level 4 to 2).
Fertilizer: Increase fertilizer to rate 2 (100 to 175 ppm N/0.7 to 1.2 mS/cm EC). If growth is slow, apply a balanced ammonium and nitrate-form fertilizer with
every other fertilization. Maintain medium pH of 5.8 to 6.2 and EC between 1.0 and 1.5 mS/cm (1:2 extraction).
Growth Regulators: Generally not needed.

Stage 4
Soil temperature: 59 to 64°F (15 to 18°C)
Light: Up to 5,000 f.c. (53,800 Lux) if temperature can be controlled.
Moisture: Same as Stage 3.
Fertilizer: Same as Stage 3.
Note: Gaura seed is a nutlet and may have up to 4 seeds, so there may be greater than one seedling per cell.

Growing On to Finish
Container Size
4.5 to 6-in. (11 to 15-cm) or quart pots: 1 plant per pot
Gallon (18-cm) pots: 1 plant per pot

Media
Use a well-drained, disease-free, soilless media with a pH of 5.5 to 6.2 and a medium initial nutrient charge (EC 0.75 mmhos/cm).
For overwinter production, bark-based media is recommended for better drainage to protect plants from root rot due to being too wet.

Temperature
Nights: 50 to 64°F (10 to 18°C)
Days: 59 to 70°F (15 to 21°C)
Sparkle Gaura can be grown at lower temperatures (frost-free cold frame/poly house); however, crop times will be increased.

Light
Maintain light levels as high as possible (DLI >= 15 mol) while maintaining moderate temperature.

Photoperiod
Sparkle Gaura is a facultative long-day plant and requires 13 hours or longer daylength for uniform and faster flowering.

Irrigation
Grow plant on slightly dry side but do not allow plant dry to wilt.

Fertilizer
Apply fertilizer at rate 3 (175 to 225 ppm N/1.2 to 1.5 mS/cm) using predominantly nitrate-form fertilizer with low phosphorus and high potassium. Maintain media
EC at 1.5 to 2.0 mS/cm and pH at 5.8 to 6.2.
For a constant fertilizer program, apply fertilizer at 75 to 100 ppm N (0.5 to 0.7 mS/cm) while maintaining the above recommended EC and pH ranges.

Growth Regulators
Sparkle Gaura is responsive to tank mix of B-Nine/Alar (daminozide) 2,500 ppm (3.0 g/l 85% formulation or 4.0 g/l of 64% formulation) and Cycocel (chlormequat) 750-1000 ppm (6.4-8.5 ml/l 11.8% formulation or 1.0-1.3 g/l of 75% formulation). Repeat if necessary.

In northern European conditions: 2,500 ppm BNine/Alar (3.0 g/l 85% formulation or 4.0 g/l of 64% formulation) works well. Multiple applications may be necessary.

Pinching
Pinching is not needed.

Spacing
Can be grown pot tight.

Crop Scheduling
Sow to transplant (288-cell plug): 5 to 6 weeks
Transplant to flower (annual production):

Container Size: 4.5 to 5-in. (11 to 13-cm) or Quart pot
Number of Plants: 1 plant per pot
Warm Production (@68F/20C): 7 to 8 weeks
Cold Production (@55F/13C): 11 to 13 weeks

Container Size: Gallon (18-cm) pot or 6-in. (15-cm)
Number of Plants: 1 plant per pot
Warm Production (@68F/20C): 8 to 9 weeks
Cold Production (@55F/13C): 12 to 14 weeks
Spring Production: Sow in January for natural flowering in early May to early June dependent on temperature.
Overwinter Production: Sow in July to early September for natural flowering mid to late May of the following year.
Plants from overwinter production flower about 1 to 2 weeks earlier and are about 1/3 taller and bushier than plants from Spring production under the same
environmental conditions.

Common Problems
Insect: Watch for aphids.
Disease: None

Garden and Landscape Information
• Sparkle Gaura is first-year-flowering perennial in
USDA Hardiness Zones 5b to 9. No vernalization
is required.
• Plant in full sun to part shade after all danger of
frost is past.
• Space plants 12 to 15 in. (30 to 38 cm) apart in
well-drained soil.
• After plants are established, Sparkle Gaura is quite
drought tolerant.
• In areas subject to wet winter conditions and frequent temperature fluctuations, roots may be
prone to root rot pathogens affecting Gaura’s
ability to overwinter.
• Garden height is 20 to 30 in. (50 to 75 cm); spread
is 12 to 20 in. (30 to 50 cm).
