Cute game, I liked the art style.
I think interact would have been more comfortable on spacebar, since you're not using it for another more important action.
I liked the selection of flowers, but I think I would have liked if the flowers grew slower, but I could build up a stock. maybe try to predict the demand for each of the flowers for the day. The mechanics lend themselves to garden tending, and I think exploring that further would be a cool way to grow the game should you desire.
