10 Low Growing Annuals That Bloom All Summer: Sun-Loving Ground Covers for Instant Garden Fillers

If you want to turn your garden into a honeybee hotspot while adding delicate charm, sweet alyssum is your secret weapon. This low-growing annual creates a fragrant, flower-filled carpet that bees can't resist, all while thriving in spots where other plants struggle.

Plant sweet alyssum in full sun to partial shade along borders, pathways, or as edging—it self-seeds happily for continuous blooms from spring until frost. The tiny white, pink, or purple flowers release a light honey scent that attracts pollinators, making it ideal for pollinator gardens. Even better, it tolerates poor soil and drought once established, so it’s perfect for urban gardens or rocky landscapes.

Beginner gardeners will love how easy it is to grow—just sprinkle seeds directly where you want them to bloom. Urban gardeners can use it in containers or window boxes to add color and fragrance without taking up space. 🌿

Tired of choosing between pretty flowers and practical ground cover? Creeping thyme solves both problems with its fragrant foliage and delicate purple blooms that repel pests while looking stunning between stepping stones or in rockeries.

This hardy perennial spreads effortlessly in full sun to partial shade, thriving in well-drained soil where other plants might struggle. The aromatic leaves deter common garden pests like aphids and cabbage moths, making it a natural protector for nearby vegetables. Simply plant plugs 12-18 inches apart for a dense carpet that stays green all season long.

Perfect for kitchen gardeners and urban spaces, creeping thyme adds culinary value too—harvest leaves fresh for cooking or dry them for winter use. Its drought tolerance makes it ideal for water-wise landscapes where foot traffic is light. 💚

Native to arid regions, portulaca stores water in its thick leaves and blooms most prolifically in full sun and sandy or rocky soil. Deadhead spent flowers to encourage continuous blooming, and enjoy its self-cleaning habit—no messy seed pods to remove. Perfect for rock gardens, pathways, or containers, it even tolerates light foot traffic.

Urban gardeners and desert landscapers will love how portulaca transforms dry spaces into vibrant, low-water havens with minimal effort. 🌻

If your garden battles salty winds, sandy soil, or relentless coastal breezes, Lobularia maritima—also called sweet alyssum—is your secret weapon. This salt-tolerant annual thrives where most plants wilt, turning harsh edges into fragrant, flower-filled havens with almost no effort.
