UK_Palms 1,326 Report post Posted August 30, 2021 Trachycarpus Fortunei maybe, however if you see lows below 0F and 200 consecutive hours below freezing each winter you can forget about it. A low of 5F and 100 hours below freezing can defoliate them in prolonged, cold-winter climates. What was your lowest temperature last winter and your lowest during the past 10 years?

Allen 1,269 Report post Posted August 30, 2021 The standard medium size Sabal minor (Toughest variety you can get) or needle palm planted protected near south side of house. Only trunking palm to try is Trachycarpus which will need protection every year. Quote Share this post Link to post Share on other sites
EvanM 2 Report post Posted August 30, 2021 (edited) What part of Michigan are you in? Rhapidophyllum hystrix (needle palm) and Sabal minor (dwarf palmetto) are quite hardy, especially when established, although they need summer heat/humidity to thrive. How are your summers?

Looking at the map, I wouldn’t count on any kind of heat island or 6b section to help you. I would suggest doing what @Allen and I mentioned: picking up a R. hystrix or hardy S. minor and planting it in a relatively sheltered, south-facing location (Is your laundry vent on the south side?). First few years at minimum you will want to protect it during the winter (incandescent Christmas lights and a wrap). Quote Share this post Link to post Share on other sites

UK_Palms 1,326 Report post Posted August 30, 2021 You're on the outskirts of Detroit I see and the main airport station is pretty close to you. According to the Wayne County airport station on Wunderground, they had 17 consecutive days/nights below freezing (400+ hours) back in February and an absolute low of -3F. In January 2019 the airport station recorded -15F. Detroit has a record low of -20F and the airport station probably runs a shade warmer than New Boston due to being within Detroit's UHI. I can't see any palm surviving the winters unless it is heavily protected most years. Even right in the centre of Detroit. Quote Share this post Link to post Share on other sites
Chester B 2,935 Report post Posted August 30, 2021 I'm from the Canadian side - there are no palms that will survive unprotected. Simply too cold for too long. You can have success with Sabal minor and Needle palms as long as you can protect and provide supplemental heat. Since they don't trunk they will be easier to box in. 1 Quote Share this post Link to post Share on other sites
