I think you should remove the word micro on your heading. This defitnally is not a micro list. It's a huge collection.
I would also like to know how you grow your highlanders and highland hybrids. I realised you have quite a few highlanders with you. Would sure like to learn from you. It is my dream to grow N. macfarlanei. Just love this highland.
Do you have a picture of your N. petiolata?
