Origami

Origami&#153; is a perennial bred by Goldsmith Seeds for first-year blooming. 'Origami' come in six varieties, blue & white, pink & white, red & white, rose & white, white, and yellow. Use as either an annual or a perennial.

Specifications

 * Crop Time: 20-24 weeks
 * Container Size: jumbos - 6 in. (15 cm.)
 * Exposure: filtered shade to full sun
 * Height: 14-16 in )35 - 40 cm.)
 * Width: 10-14 in. (25 - 30 cm.)

Flowering

 * Time Frame when plants are receptive to flower initiation: 4 – 6 leaves present.
 * Flowering Type: Facultative Long Day Plant – long days enhance flowering.
 * Specific Flowering Mechanism: A vernalization treatment is needed to initiate flowering. ‘Origami’ can be vernalized once the plugs have established root systems and are at least 6 – 8 weeks old. Light intensity enhances flowering.

Plug Culture
Expect radicle emergence in 6 – 8 days.
 * Germination –Optimum conditions for seedling development that begins the day the crop is sown until cotyledon expansion.
 * Seed Handling: No special treatments are needed prior to sowing. Chilling the seed prior to sowing is not advisable. It may be desirable to double sow larger plug trays.
 * Cover: No cover is necessary. However,seeds may be covered with a thin layer of coarse vermiculite to maintain moisture levels.
 * Media: pH: 5.5 – 5.8, EC: 0.5
 * Light: Light is necessary for germination. If utilizing a chamber, providing a light source of 10 – 100 foot candles (100 – 1000 lux) will improve germination and reduce stretch.
 * Temperature: 70°– 72°F (21°– 22°C)
 * Moisture: Wet (4) until radicle emergence. Then reduce moisture level to medium (2).
 * Humidity: 100% until radicle emergence then reduce to 70%.
 * Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration,allowing better penetration of oxygen to the roots.
 * Plug Bulking –Optimum conditions during the vegetative period,beginning at cotyledon expansion,needed for the root to reach the edge of the plug cell.
 * Media: pH: 5.5 – 5.8, EC: 0.5 – 0.75
 * Temperature: 65°– 68°F (18°– 20°C)
 * Moisture: Alternate between moisture levels moist (3) and medium (2). Allow media to approach level (2) before re-saturating to level (3).
 * Humidity: 65 – 70%. Provide horizontal airflow to aid in drying down the media through evapotranspiration under cool,low light conditions.
 * Fertilizers: 50 – 100 ppm Nitrogen weekly or as needed with a calcium-based fertilizer (13-2-13 or 14-4-14).


 * Plug Flower Initiation –Optimum conditions to make plant receptive to flower initiation.
 * Light: Provide 3500 – 4500 foot candles (12 – 15 total moles or 35,000 – 45,000 lux) to hasten flower induction. Supplemental lighting under low light conditions at 350 – 450 foot candles (35,000 – 45,000 lux) will enhance shoot and root growth.
 * Temperature: Maintain night temperatures within 40°– 50°F (5°– 10°C) for 14 – 21 days. Bred in Gilroy,California,‘Origami’ is more tolerant of higher vernalization temperatures than other Aquilegia. This is an advantage for Southern growers.
 * Average Daily Temperature (ADT): After vernalization ADT is 65°– 67°F (18°– 19°C).
 * Fertilizers: 100 ppm Nitrogen as needed of a calcium-based fertilizer 13-2-13 or 14-4-14). Growth Regulators: If necessary,‘Origami’ will respond to B-Nine (daminozide) at 2500 ppm. PGR’s are more effective in the early stages of production.
 * Fungicides: Apply preventative fungicides for Botrytis prior to vernalization.

Growing On
‘Origami’s’ unique habit easily adapts to a variety of container sizes. Suitable for packs and larger containers,‘Origami’ naturally adjusts to finish habit to fit proportionally into whatever container you choose – without the use of growth regulators!
 * Transplant Ready: 9 – 10 weeks from sow in a ‘288’ tray.
 * Finish Bulking –Optimum conditions during the vegetative period, beginning at transplant,needed for the root to reach the edge of the container.
 * Media: pH: 5.5 – 5.8, EC: 1.0 – 1.2
 * Light: Provide 3500 – 4500 foot candles (12 – 15 total moles or 35,000 – 45,000 lux) to hasten flower induction. Supplemental lighting under low light conditions at 350 – 450 foot candles (35,000 – 45,000 lux) will enhance shoot and root growth.
 * Temperature: After crop has been vernalized,night temperatures may be increased to 60°– 65°F (16°– 18°C). Cooler temperatures are tolerated but will increase the final crop time. Keep day temperatures cool. High night temperatures will negate the vernalizing process and reduce uniformity to flower.
 * Average Daily Temperature (ADT): After vernalization ADT is 65°– 67°F (18°– 19°C).
 * Moisture: Alternate between moisture levels wet (4) and medium (2). Allow media to approach level (2) before re-saturating to level (4).
 * Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration,allowing better penetration of oxygen to the roots.
 * Fertilizers: Aquilegia is a moderate feeder. Alternate between potassium and calcium-based fertilizers at 150 – 200 ppm Nitrogen as needed. Under cool weather conditions,avoid ammonium-based fertilizers that may encourage root rot problems and excessive vegetative growth or stretching. Excessive phosphorus will promote stretching.
 * Growth Regulators: If necessary,‘Origami’ will respond to B-Nine (daminozide) at 2500 ppm. PGR’s are more effective in the early stages of production.
 * Finish Flower Initiation –Optimum conditions to make plant receptive to flower initiation.
 * Temperature: Locate plants in a cool area where they will not freeze for 14 – 21 days. The upper temperature threshold for proper vernalization is 40°– 50°F (5°– 10°C). Plants will grow slower at lower temperatures. If plants turn purple, temperatures are too low.
 * Average Daily Temperature (ADT): After vernalization ADT is 65°– 67°F (18°– 19°C).

Pre-Shipping Techniques to Enhance Post Harvest Quality

 * When to treat: 1 – 2 weeks prior to finish or shipping.
 * Fertilizer: Calcium nitrate at 150 ppm Nitrogen. A calcium chloride spray at 150ppm Nitrogen applied one week prior to shipping may discourage flower drop in shipment.
 * Common Diseases: Powdery Mildew
 * Common Pests: Spider Mites, Aphids

Scheduling

 * Total crop time: 20 – 24 weeks
 * ‘288’Plug crop time: 9 – 10 weeks
 * Vernalization in finish container: 2 – 3 weeks. A well established root system is required before plants are vernalized.
 * 4”crop: 9 – 11 weeks

Product Use
Packs, pots, containers, mass plantings. Traditionally a spring blooming perennial, ‘Origami’ has been bred for an extended bloom window that will increase its value in the landscape.
