Plant Description

Article Type: (GOLD NUGGET SEED®)
Life Cycle: Perennial
Family: Rosaceae
Origin: Hybrid Origin
Special Features: Compact and free-flowering seed strain with orange-red blooms, reblooms often September-October. Can withstand dry periods in any good garden soil.
Historical: Once, while Wilhelm Schacht was on Musala, in the Rila mountains with King Boris III of Bulgaria, he found a natural G. hybrid, which he then named G. x borisii after his employer. The name x borisii for the cross between G. bulgaricum and Geum reptans, was then mistakenly given to several breeds of G. coccineum. Later, Georg Ahrends also named his new breeds G. x borisii plus cultivar. The true G. x borisii can still be found in the UK but is seldom cultivated.

Sowing Rates/Trays: 3 - 4 per cell
Plug tray recommended size(s): 72 / 128
Sowing Direction:

(15) Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Seeds must be covered thinly. Do not cover very small seeds, but tightly press into the earth. Keep in cooler conditions after germination occurs.

Best Sowing Date
(northern Hemisphere, Field condition):
Anytime
Sowing Time Hint: Varying temperatures, night 18°C, day 26°C, of benefit.
Sowing to Germination: 3 - 4 weeks
Germination to Transplant: 4 - 6 weeks
Transplanting to Potting: 6 - 8 weeks
Cutting back at Transplanting: Cut-back once to keep more compact.
Container Size(s): 1 plug per 8/9 cm (3 1/2") / 1-2 plugs per 11/12 cm (4 1/2") / 2-3 plugs per 15 cm (6")
Vernalization: A prudent recommendation would be to provide 6-12 weeks at an average daily temperature of 40°F (5°C). Exposure to cold may not be necessary for flowering but might improve quality.
Forcing: An obvious place to experiment - following vernalization - would be raising daytime temperatures to 60° - 65°F (15° - 17°C). Provide 16 hours of continuous lighting. During the short days of winter, provide a night interruption lighting of 4 hours between 10:00 p.m. and 2:00 a.m.
Fertilizer: Medium (150-200 ppm)
