Hi, Norm...sorry to appear a bit thick, but I'm not sure what is the basis for doubting whether or nor they would grow true to type, especially as you refer to them as 'fresh' seed.
Having said that (although I don't grow them) I can say that they have a purpose in the garden for covering say garage walls or unsightly fences. The only maintenance required is to cut them back to ground height in the spring...of course, they don't have any scent, which is a priority for me when contemplating growing SPs.
