Question
I have read all of your rose of sharon answers and they were very helpful.  Do you know where I can purchase red rose of sharon seed?  Every place I find sells assorted seed and I just want red.     Thank you.   Bill

Answer
Hi Bill,
I'm sorry this took so long to answer.  Thanx for your question.  Go to ebay and do a search for red rose of sharon or rose of sharon.  There are some Rose of Sharon that are almost red but they're more of a reddish-purple than a red like in the hibiscus.  Now, there are true red hibiscus that are hard to zone 4 with huge red flowers.  There are some blogspots you might find some red hibiscus seeds.  I hope this helps.
