My Mother was a real green thumb with most any plant, she taught me about adding coffee grounds, egg shells, banana peels, compost...etc to my house plants and garden. Anyway, her favorite flower was a Poinsettia, and she passed away weeks before Christmas last year. I ended up saving the yearly Poinsette my job sends me. It's doing well and I really want it to bloom this year. I need to read up on it more.
