to my surprise walking our neighbourhood i bumped into as described above a small lot of zinnias........i stopped took a photo and the owner who saw me interested said these flowers sow themselves from year to year.he picked a dead-head for me.
my question is will i get something like what i saw......height and diametre?next year?

Probably yes but it will depend on your soil and sun conditions.

thanks did you see my other question?

I see the one question here about what you will get next year as far as size/height/diameter, etc. If there is another question on a different thread I 'm sure it will be answered in due time.

Thankyou
