Companion Plants
Growing red Aubrieta plants changed how I think about year-round color—this tough little groundcover delivers bold blooms from early spring until frost, all while barely asking for water. 🌿 The first time I saw it spilling over a rocky slope, I knew it was a game-changer for my dry, sunny borders where other plants give up by July.
Here's the secret: Aubrieta thrives in poor soil and full sun, making it perfect for spots where nothing else survives. You'll need well-draining soil (even rocky or sandy), 6-8 hours of sunlight daily, and almost no water once established—just a quick drink after planting and during extreme drought.
The flowers start in late winter or early spring, with a second flush in fall, and the foliage stays lush and evergreen.
By late spring, your garden will be transformed with vibrant red carpets that attract bees and butterflies while keeping weeds at bay. The plants stay compact—just 6-12 inches tall and wide—so they fit perfectly in rock gardens, between stepping stones, or cascading over walls.
Prune back after flowering to encourage a second bloom cycle, and you'll have color when most gardens are brown.
Whether you're fixing a bare slope, brightening a shady corner with companion plants, or just adding year-round interest, Aubrieta delivers. The best part? It's nearly indestructible—once planted, it'll spread and multiply for years with almost no effort. Let's get yours growing!

What you need
- ● Red Aubrieta plants: Choose between seeds (start indoors 6–8 weeks before last frost) or potted plants (look for healthy, vibrant foliage with no signs of pests).
- ● Well-draining soil: A mix of 50% potting soil, 30% perlite or coarse sand, and 20% compost (or a pre-mixed cactus/succulent blend).
- ● Containers or garden bed: For containers: 6–12" pots with drainage holes (1–2 plants per 6" pot).
- ● For garden beds: Full sun exposure (6+ hours/day) and rocky or sloped areas (Aubrieta thrives in poor soil!).
- ● Slow-release fertilizer: A balanced 10-10-10 or low-phosphorus (5-10-10) blend to avoid leaf burn.
- ○ Mulch (optional but helpful): Gravel or pebbles (1–2 inches) to retain moisture and improve drainage.
- ● Gloves (gardening or nitrile for seed-starting).
- ● Trowel or small shovel (for transplanting).
- ● Spray bottle (for misting seeds) or watering can with a fine rose.
- ● Pruning shears (for shaping or deadheading).
- ○ pH testing kit (optional but useful—ideal pH: 6.0–7.0).
- ● 🌡️ Temperature matters: Aubrieta loves 60–75°F but can tolerate brief chills (down to 20°F once established).
- ● ✨ Drought-proof prep: Water deeply once a week after establishment—these plants hate soggy roots!
- ● 🎯 Sunlight shortcut: If your yard is shady, place plants in a south-facing window or use a grow light for 4–6 hours/day.
How to plant and care for red aubrieta for vibrant year-round color
This hardy ground cover thrives with minimal fuss—here's how to plant and maintain it for bold, drought-resistant beauty.
🪴 Step 1: Choose the Perfect Spot for Planting
Red aubrieta loves full sun—at least 6 hours daily—but tolerates partial shade in hotter climates. I always pick a location with well-draining soil, like slopes or rocky areas where water pools. Test drainage by digging a 6-inch hole—if it fills with water after 10 minutes, amend with sand or gravel.
This plant spreads aggressively, so plan for 12-18 inches between plants if using as a border. For ground cover, space them 6-9 inches apart. The vibrant red blooms will cascade beautifully over walls or edges once established.
🌱 Step 2: Prepare Soil and Plant Correctly
Loosen the soil to a depth of 8-10 inches with a garden fork, breaking up any compacted layers. Mix in a 2-3 inch layer of compost to enrich the soil without making it too heavy. Aubrieta hates soggy roots, so avoid adding organic matter if your soil is already rich.
Dig a hole twice as wide as the root ball but only as deep as the container. Gently remove the plant, tease apart any circling roots, and place it so the top of the root ball sits ½ inch below soil level. This ensures stability and prevents rot. Backfill with native soil, pressing lightly to eliminate air pockets.
💧 Step 3: Water Deeply and Establish the Plants
Water immediately after planting to settle the soil and remove air gaps. Give the area 1 gallon of water per plant for the first week, keeping the soil evenly moist but not soggy. Aubrieta is drought-tolerant once established, but new roots need consistent moisture for the first 4-6 weeks.
After two weeks, reduce watering to once weekly unless your area experiences extreme heat or drought. You'll know it's thriving when you see new growth within 3-4 weeks—the deep green foliage signals strong root development.
☀️ Step 4: Maintain for Continuous Blooms
Fertilize lightly in early spring with a balanced 10-10-10 formula (½ teaspoon per plant). Aubrieta doesn't need much—over-fertilizing causes weak growth and fewer blooms. Deadhead spent flowers in late spring to encourage a second flush of color, but leave some for winter interest.
This plant handles drought beautifully once established, but water deeply once monthly during prolonged dry spells. Mulch lightly with ½ inch of gravel to suppress weeds and retain moisture without smothering the low-growing foliage.
✂️ Step 5: Prune and Divide for Long-Term Health
Cut back one-third of the plant in early spring to promote bushiness and remove any winter-damaged growth. Aubrieta spreads rapidly, so divide clumps every 3-4 years in early fall. Dig up sections with a sharp spade, separate into 3-inch chunks, and replant immediately.
This is the secret to keeping your aubrieta vibrant—regular division prevents overcrowding and rejuvenates older plants. You'll notice a surge of new growth within 2-3 weeks after dividing, proving how resilient this plant truly is.
Tips & tricks for perfect red aubrieta planting and care
Here's what I've learned after years of growing vibrant red aubrieta—these tricks will help you avoid common mistakes and keep your plants thriving.
Sunlight Secret: While red aubrieta loves full sun, I've found that in extremely hot climates, it actually benefits from morning sun and afternoon shade. The key is to avoid the harshest afternoon rays that can scorch the delicate foliage. If your location gets intense afternoon heat, consider planting near a structure that provides light shade during those hours.
Soil Test Hack: Before planting, do a quick soil test by digging a 6-inch hole and filling it with water. If it drains completely within 10 minutes, your soil is perfect. If it takes longer, mix in sand or gravel to improve drainage. I've seen soggy soil completely ruin aubrieta plants—this simple test saves so much trouble later.
Planting Depth Tip: The ½ inch below soil level placement is critical—it prevents rot while ensuring stability. I like to make a small mound of soil when planting so I can easily check the depth. If you plant too deep, the plant may suffocate; too shallow and it won't anchor properly. Use your finger to verify the depth before backfilling.
Watering Wisdom: The first 4-6 weeks are crucial for root establishment. I've found that watering early in the morning prevents evaporation and fungal issues. After the initial period, let the soil dry slightly between waterings—this encourages deep root growth. The deep green foliage you'll see after 3-4 weeks is your signal that roots are developing properly.

Frequently asked questions
Got questions about growing and caring for red aubrieta plants?
You’re not alone! Here are answers to the most common queries to help you keep your cascading red blooms thriving year-round.
When is the best time to plant red aubrieta?
For perennial results, plant red aubrieta in early spring or fall when soil temps are mild (50–70°F). This gives roots time to establish before summer heat or winter frost. If using as an annual, spring planting works too—just expect blooms to fade after the first frost.
How often should I water red aubrieta?
Once established, red aubrieta is drought-tolerant—water deeply but infrequently (every 1–2 weeks in dry spells). New plants need weekly watering until roots spread. Overwatering causes root rot, so prioritize well-draining soil (like rocky slopes or containers with drainage holes).
Do I need to prune red aubrieta after it blooms?
Yes! Trim back spent flowers (deadhead) to encourage more blooms and a tidy look. For perennials, cut back 1–2 inches in early spring to promote fresh growth. Avoid heavy pruning in late summer—this can delay fall blooms.
What pests or diseases should I watch for?
Red aubrieta is resistant but may face aphids or powdery mildew in humid climates. Treat aphids with a soapy water spray; improve airflow to prevent mildew. Slugs? Use organic bait or beer traps—these plants are too tender to compete!
Can I grow red aubrieta in containers or hanging baskets?
Aubrieta thrives in containers (6+ inches deep) with fast-draining mix (add perlite or sand). For hanging baskets, choose trailing varieties like ‘Doctor Mule’ and water from the bottom to avoid soggy roots. Pro tip: Mix with thyme or sedum for a drought-proof combo!
