Growing On:
Family: Crassulaceae
Origin: Rocky hillsides along the Amur River - the border between China and Russia
Special Features: This is the true species that is often misidentified in the trade with Sedum ellacombianum.
Hairy on all of its parts, 'Goldilocks' produces tight round hummocks and flowering in the first year
History: Introduced by JELITTO PERENNIAL SEEDS in 2006
Colour: Rich golden glowers
Natural Flowering Period: August - September
Winter Hardiness Zones: Z4-8
Growth Habit: Tight low growing mounds
Foliage: Attractive, narrow lance-shaped leaves
Height with Flowers: 20 cm (8'')
Spacing between Plants: 25 cm (10'')
Soil Requirements: Well-drained, gritty soils, pH 5.8 - 7.2
Location: Full sun
Use: Plant in troughs or the rock garden with other sedums and drought tolerant plants like Oenothera 'Silver Wings', Dracecephalum 'Blue Dragon' and Thymus 'Magic Carpet'
Specialities: First-year flowering if sown early. No maintenance required
Grams per 1000 Seeds: 0,040
Seeds per Gram: 25000
Seeding Recommendation: 0,25 g / 1000 plants
Sowing Rate: 10-12 seeds per cell
Plug tray recommended size(s): 128, 288, or open flats
Germination: These are very tiny seeds which should be mixed with the finest sand or talcum for an even sowing. Do not cover with compost, only press them in gently. Irrigate from the bottom or with a hand-sprayer, so that the seeds will not be washed away. Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C (68°F). Keep in cooler conditions after germination occurs.
Best Sowing Dates: November - March
Sowing to Germination: 2 - 4 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to Salable Plant: 6 - 10 weeks
Cutting-Back at Transplanting: Not necessary
Container Size(s): 1 plug per 8/9 cm (3 1/2''); 1 plug per 11/12 cm (4 1/2'')
Vernalization: There is no current research on vernalization but a prudent recommendation for any perennial would be 6-12 weeks (a few might need 15 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.
Fertilization: Light (100-150 ppm)
