General Comments:

They are included here because they are valuable to insects and because they are lovely and good to have in a native garden if you are lucky enough to have them naturally.  

Data on culture has been assumed from where this grows in nature -- it is not typically grown and no reliable data appears to be available.

Can parasatize southern pines leading, in heavy infestations, to loss of vigor.
