queen palm syagrus romanzoffiana santa catarina and Phoenix sylvestris

[ShaneHarding]

Hi guys I’m fairly new to tropical gardening started this year in may and I have fallen head first into things and have learnt an awful lot already . 

I've already got 2 x Phoenix canariensis  - 5x Washingtonia robustas and a trachycarpus fortunei which are doing really well but I want to branch out abit and see what’s possible to grow in my area!
I live in the coastal village of Braunton in North Devon - south west England zone 9b and I’m around 10 meters above sea level .

I'm wondering if anyone has tried to grow syagrus romanzoffiana santa catarina (supposedly hardy queen palm ) and Phoenix sylvestris (silver date palm) I’m the south of England or even England in general with any success? 
 

thanks in advance

Phoenix Sylvesteris is more cold hardy than the Queen Palm.
