So, it isn't wrong.


temperatures given by David were 45-50F, wrong!

After reading Dallas historical temps, it's likely C. revoluta could
be used in a microclimate....

"Temperature range is from 15 to 110 degrees F (-11 to 42 C).
Temperatures in the high teens may frost-damage leaves which may turn
yellow or brown. Remove these to reduce stress on the plant and
encourage new leaves in the spring. If temperatures fall below 15,
the sago may die, however, as long as the trunk and leaf crown is hard
wood, it should recover. If the trunk turns soft, your sago may be
damaged beyond recovery. Our field of sago palms survived 11 degrees,
a century low in South Texas, however large live oak trees planted
throughout the "sago patch" provided some protection. We removed all
the damaged leaves and the sagos grew new ones the following spring.

I think a big point you may be missing is that these are considered to
be specimen plants and for that application are not practical to use
as a foundation specimen or in a design because they are not reliably
hardy in Dallas, TX. It indeed would not be worth the money or time
investment you'd need to make in the landscape.
