Nasturtium
Nasturtiums bring a burst of color to your garden while working quietly as a natural pest repellent. These trailing or bushy plants produce bright blooms in shades of orange, red, and yellow, and their peppery scent drives away mosquitoes, aphids, and whiteflies. While not as aromatic as herbs like basil or mint, nasturtiums act as a trap crop, attracting pests away from more vulnerable plants. This makes them an excellent companion for vegetables like tomatoes, beans, and cucumbers. Nasturtiums grow well in poor soil and need only moderate watering and full to partial sun. They’re also easy to grow from seed, making them a great pick for beginner gardeners. Bonus: the leaves and flowers are edible and add a peppery kick to salads and dishes.
