Sure. I have ordered from them twice. This season, one frutescens which germinated at 60%. The two annuums I won't start until March, but their seeds have always been good performers for me.
I have ordered from them a few times over the past several years. Their seeds have always done very well for me, and they usually arrive in a couple of weeks or so. I have never had any issues with them coming from overseas. THSC is an excellent seed vendor.
