I know how you feel. Two years ago I got an Easter lily, didn’t last a week.
Our church youth gave all the ladies at church begonias for Mother’s Day. I put them in a hanging basket outside.......so far so good.
I’m fine with veggies and herbs —— but ebony black is my thumb when it comes to flowers or any kind of houseplant.
I kill all houseplants...usually. I have one that thrives. It’s a plant that friends sent me after my Mom passed away in 2001. She had a very green thumb ( why didn’t I get that gene?), I think she has a hand in my care of that plant. :)
