Grandpa Ott or Star of Yelta - can't tell difference

I purchased a packet of seeds a year ago and now have hundreds of Grandpa Ott blooms this year. I also bought some Star of Yelta seeds.

I held them side by side and I can't see a difference. They look identical!!!! I compared two different flowers, - bloom deep, bright purple, slightly lighter streaks (5 evenly spaced to look like a star). They match the pictures etc. of what people call Grandpa Ott's.

I'll try and post a pic - I'm wondering if what I originally understood was Grandpa Ott is really Star of Yelta or if the Star of Yelta are Grandpa Ott.

Any thoughts?

OK, now I feel silly - did a quick search on Yelta and found several postings - saying the same thing. Guess it pays to read before posting. :-) Anyways, I love this site, welcome the chance to post and ask questions and reading what other people say.

Have a great weekend.
