RUDBECKIA fulgida var. fulgida
Plant Description
| Article Type: | (GOLD NUGGET SEED ®) |
| Life Cycle: | Perennial |
| Family: | Asteraceae |
| Origin: | USA: upper south and lower midwest |
| Special Features: | A long-flowering botanical variety with dark green foliage that blooms after 'Goldsturm' until frost. Graceful botanical variety and great season-extender. With more open habit than 'Goldsturm'. |
| Basic Colour: | (yellow / gold) |
| Flower Colour: | yellow-orange with dark center |
| Natural Flowering Period: | September - November |
| Winter Hardiness Zones: |
Z3 - Z8
|
| Foliage: | dark green |
| Growth Habit: | erect / clumping |
| Height with Flowers: | 80 cm |
| Spacing between Plants: | 70 cm |
| Soil Requirements: | average |
| Location: | |
| Characteristics: | groundcover |
| Usage: | honey-bee food plant / suitable for cutting |
| Grams per 1000 seeds: | 0.83333 Gram |
| Seeds per Gram (does not correspond to the number of plants!): |
1200 |
| Sowing Rates/Trays: | 2 per cell |
| Plug tray recommended size(s): | 72 / 128 |
| Sowing Direction: |
(16) See 15 with the exception of germination being slower and more irregular. This poses no problems. (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: | Light-germinator, do not cover, night 18°C, day 26°C. |
| Sowing to Germination: | 3 - 4 weeks |
| Germination to Transplant: | 3 - 10 weeks |
| Transplanting to Potting: | 4 - 6 weeks |
| Cutting back at Transplanting: | Not Necessary. |
| Container Size(s): | 1-2 plugs per 11/12 cm (4 1/2") / 2-3 plugs per 15 cm (6") |
| 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: | There has been no research, but 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. Some later flowering species can be forced in 14 - 16 weeks and perhaps sooner at warmer temperatures. Further experiments are warranted. |
| Fertilizer: | Medium (150-200 ppm) |
