Thank you for the welcome too grannygarden
I do understand that that's an unending process, but I don't mind that - I love to work in the garden
I hope I'm not too quick with my decisions, but I just found out that Mid America Garden has an option to ship to Europe but the minimum order to EU is 100$. I would order from domestic nurseries where I can get less irises, but I'm sooo picky with the cultivars :D
So.. I'm from a country from EU and to answer your question - I'm in the zone 6. About the markings of irises - I will for sure make a map, I already have one for my roses (which are btw. beige/light yellow/peach colored). Thank you about the tips of the height and time of blooming - I will check this out.
tveguy3 thanks again for the info
If anybody can also say anything about the comparison of Coffee Trader and Dragon Dance I would be pleased
Edit: forgot to answer the photo question... each point on the photo represents a rhizome. So a small triangle represents one cultivar.
