Which flowers are best suited for window boxes?

For window boxes, geraniums, impatiens, and pansies are really great because they bloom for ages and don't need that much attention 🌺. Petunias look amazing too and last until the first frost, but you have to water them regularly. If you've got more shade, go for impatiens or begonias - they'll forgive you if you skip watering for a day. The main thing is just to use loose soil and deadhead regularly, then you'll have color all summer long 😊
