I like weeping plants a lot. I have read that there is a kind of Skipper Butterfly that only lives in a mountain in South Korea. It has a similar name in Korean too.
I would love to have a garden like yours. It is amazing. What a nice thing to do and good for the world. The unknown low growing orange flowering plants might be Gazania. If you have any Passion Vine seeds to spare, I would like to buy or trade for some. I have Campsis radicans vine seeds aplenty.
Beautiful garden! Do you every see any fritillaries? Oh, I guess that's one in your avatar lol Gulf fritillary? How about hairstreaks? (the little gray butterflies)
