I'm a guy and i want to have a garden when i am older what type of flowers are good to have ?
It really depends on your soil type, the climate, and the amount if sun you receive. Hostas grow without much effort. Coleuses are also pretty easy.
I like daisies and bluebonnets.
Pansies or lilacs
Delphiniums, Bluebells,Lavender, etc.
