I think verbena is an ideal plant for window boxes because it comes in so many gorgeous colors like white, red, and pink. It is a hardy plant that prefers full sun with very little water, which I find makes it wonderfully low-maintenance. I also love putting mine in hanging baskets or on balconies for a cascading effect. This versatile flower is perfect for anyone who wants constant color with minimal fuss.
5. Coleus: Vivid Foliage That Steals the Show
I am completely obsessed with coleus because it produces stunning foliage in such vivid colors that sometimes I forget it even flowers. This plant prefers a lot of bright, indirect light, which makes it perfect for windows that do not get harsh midday sun. I think the leaves look like living paintings with their intricate patterns and bold hues. It is one of my personal favorites for adding artistic flair to any window display.

I think Red Salvia is absolutely gorgeous with its spiky flowers and beautifully scented foliage that adds vertical interest. From summer to fall, this perennial does wonderfully in hot and dry climates, which I find incredibly resilient. I love how the bright red spikes attract hummingbirds right to my window. This plant is a stunning option if you want drama and height in your box.
8. Cyclamens: Bright but Toxic Beauty for Pet Owners
I find cyclamens absolutely stunning with their bright, upswept flowers that bring such elegance to my window boxes. However, I always keep in mind that the petals are poisonous and can be hazardous to cats and dogs, though thankfully not fatal. I make sure to place mine where my pets cannot reach them to keep everyone safe. Despite the toxicity concern, I think their beauty makes them worth the extra caution.
9. Petunias: Drought-Tolerant Cascades of Color
I absolutely love petunias because they are such a great plant for balconies and can tolerate some drought without complaint.

I appreciate that they do not need daily watering, making them perfect for my sometimes busy schedule. The trailing habit creates the most beautiful cascading effect I adore.
10. Dianthus: Sweetly Scented Butterfly Magnets
I think dianthus is absolutely delightful because its sweetly scented blooms attract butterflies from spring all the way to frost. I grow mine in window boxes, sunny beds, containers, and borders because they are so wonderfully versatile. The fringed petals in pink, white, and red always remind me of tiny carnations. This flower is one of my personal favorites for adding both fragrance and charm to any space.
11. Pansies: Charming Faces in Every Shade
I find pansies absolutely charming with their little faces peeking out from pots and flower boxes on my windowsill.

Their bright, happy blooms never fail to make me smile when I look outside.
13. Sweet Alyssum: A Pollinator Paradise in Miniature
I adore Sweet Alyssum because it acts as a wonderful ground cover while attracting so many beneficial insects to my window. Mine regularly brings in predatory wasps, crab spiders, lacewings, and ladybugs that help keep my garden healthy. I think growing this flower is one of the best ways to invite pollinator species to visit your living space. The delicate honey-scented blooms create such a lovely, soft carpet of white and purple.
14. Geraniums: Classic Beauty Trained to Climb
I think geraniums are absolute classics that can be trained to wrap beautifully around banisters or walls of your window boxes. They love growing in well-draining soil with watering just once a week, which I find very manageable. I give mine full sun most days with some afternoon shade to keep them blooming their best. The clustered flowers in red, pink, and white never go out of style in my book.
