Queen Palm (Syagrus romanzoffiana) is a popular ornamental palm native to South America. Seeds exhibit dormancy and slow, erratic germination requiring specific pretreatment for successful propagation.
Before sowing
Fresh seed from intermediate or mature fruits recommended; operculum perforation + 24hr water soaking yields best results (82-90% germination)
Sowing
What to expect
Tips
Use fresh seeds from mature fruits; seed storage reduces germination dramatically (less than 10% after 2 years); constant light during incubation beneficial; very high temperature (90-95°F/32-35°C) recommended; maintain high humidity; seeds are slow and erratic germinating
