I like gardening.
From my experience:
Daffodils are easy. They also multiply a lot. Tulips are hard and not worth the trouble.
Irises are great but may take until the second year until they bloom. Once they get acclimated, they produce lots of flowers.
I get all of these from White Flower Farm that was recommended by my uncle Sam many years ago. Their stuff isn’t cheap but the quality is great. I especially recommend Thalia, a daffodil which has several small flowers on each stem.
At my old house, I grew roses. They were a pain in the ass. Great flowers but the plants caught lots of diseases. There are a few photos here of the variety Tropicana.
