Syagrus romanzoffiana or Queen Palm is, like Beccariophoenix alfredii, a look alike of the cocos palm or Cocos nucifera that can replace him in landscaping in colder climates, though not colder than USDA zone 9.
It was formerly classified in the genus Cocos and bore the name Cocos plumosa. Later it was classified in the genus Arecastrum and finally in the genus Syagrus. Thus we find it often under its former names.
Its rapid growth and low price make it a coveted palm tree.
Syagrus romanzoffiana is a palm tree that grows up to 18 m. The stipe is gray, 30-50 cm in diameter, up to 15 m long and sometimes produces aerial roots at the base.
The leaves are light to dark green, pinnate and measuring up to 5 m long. The dead leaves stay long on the palm tree and removed for aesthetic reasons. The leaf sheaths serve as a breeding place for snails and caterpillars.
The inflorescence is 1.5 m long, highly branched, with a woody spathe and cream colored flowers.
The fruit is a berry, 2-3 cm long, yellow-orange and sweet. She looks like a date and is mainly eaten by birds and small mammals such as the pampavos.

Regions with short winters and wet soils
USDA zone 9-1
Leaf damage at -3 °C, dies at -6°C
water daily during growing season
Fertilize regularly during growing season (every 1-2 weeks, is a fast grower)
- soak the seeds for 3 days in lukewarm water
- sow in a moist mix
- put the pot in a plastic bag or container to keep humidity
- 35-40 °C during the day, 20-25 °C during the night (above the radiator should do the trick)
- germination time: 1 month to a few months
