Finding an amazing new plant is like falling in love, there's some initial euphoria before reality sets in -- with its compromise and more than a little trial and error. If you've made a bad call or two, don't beat yourself up about it -- too much.
A green thumb is more about perseverance than being a plant whisperer. I've killed so many plants over the years that I'd be on the ten-most-wanted stupid humans list of the plant cosmos -- if there was one. I learned from each mistake, though. I'm not sure which august personage said it, but the adage that: You don't know a plant until you've killed it at least three times can be a comfort. It has been for me, anyway.
Have a great Sunday in the garden.
