Plant Description

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.

Gram to get 1000 plants
(if sown directly into pots etc. you will need a larger quantity):
5 Gram
Sowing Rates/Trays: 6 - 7 per cell
Plug tray recommended size(s): 72 / 128
Sowing Direction:

(8) These perennial seeds germinate very irregularly over a long period. Lower temperatures of less than +5°C [41°F] are very effective. Seed trays should not be discarded prematurely. Constant moisture must be maintained. Do not leave in direct sunlight. For Alstroemeria we recommend to keep sowing for 3 weeks at approximately +30°C [86°F], then 3 weeks at +5°C [41°F], then at +21°C [70°F].

Best Sowing Date
(northern Hemisphere, Field condition):
late autumn - early spring
Sowing to Germination: 6 - 8 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)
