4. Sweet Alyssum

Don’t be fooled by its tiny blooms—sweet alyssum is a powerhouse of perfume. This low-growing plant spreads quickly, forming fragrant carpets of white, lavender, or pink flowers that look like a floral mist along borders, garden edges, or containers. The scent is light and honey-like, especially noticeable during cooler parts of the day or in early morning sun. It’s incredibly easy to grow, tolerates poor soil, and reseeds freely, making it one of the most budget-friendly ways to add aroma to your space. Sweet alyssum is also great at attracting pollinators and beneficial insects, helping your whole garden thrive while making it smell delightful.
