Flerårig pipört "Crimson Night"

Flerårig pipört "Crimson Night" - Centranthus ruber var. coccineus = Valeriana coccinea.
En unik, intressant perenn, kännetecknad av riklig och lång blomning. Långblommande och kalltålig.
Förutom soliga rabatter passar den att plantera på torra sluttningar, i stenpartier, på stenstödmurar, längs stenens kanter, på soliga trappsteg, i takträdgårdar och i planteringar mellan tegelplattor på asfalterade stigar och plattformar.
Dess genombrutna och samtidigt ganska tydligt definierade många blomställningar av ljus hallonröd färg kombineras perfekt med många fleråriga blomgrödor.

Cultural Tips:
Grams per 1000 Seeds: 2,222
Seeds per Gram: 450
Seeding Recommendation: 5 g / 1000 plants
Sowing Rate: 2 seeds per cell 
Plug tray recommended size(s): 128 or 288 
Germination: Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C. Seeds must be covered thinly. Keep in cooler conditions after germination occurs. The germination might be slower and more irregular. This poses no problems.

Scheduling:
Best Sowing Dates: Anytime 
Sowing to Germination: 2 - 3 weeks 
Germination to Transplant: 4 - 6 weeks
Transplanting to Salable Plant: 6 - 8 weeks
Cutting-Back at Transplanting: Cut-back 1-2 times; once at transplanting; once again 4 weeks later to keep more compact

Growing On:
Container Size(s): 1-2 plugs per 11/12 cm ; 2-3 plugs per 15 cm.
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 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 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: Medium (150-200 ppm).
