What to Plant With Rosemary and Lavender
Rosemary and lavender are two Mediterranean herbs that grow beautifully together, and there are plenty of plants that make great companions for them.
If you’ve been wondering what to plant with rosemary and lavender, you’re in the right place.
Both plants love full sun, well-drained soil, and dry conditions, so the best companion plants share those same needs.
In this post, we’ll explore what to plant with rosemary and lavender, why these companions work, and how to set up a garden bed where everything thrives together.
Let’s dig in.
Why Companion Planting Works With Rosemary and Lavender
Planting with rosemary and lavender works so well because these two herbs have nearly identical growing requirements.
They both originate from the Mediterranean region, which means they crave sunshine and hate soggy roots.
When you plant with rosemary and lavender, you’re creating a low-water, high-drainage garden zone.
Any plant you add should match that same environment, or it will struggle while your herbs flourish.
Companion planting with rosemary and lavender also brings practical benefits.
Rosemary and lavender both repel certain pests, and their strong aromas can confuse insects looking for weaker plants nearby.
So pairing them with the right neighbors creates a naturally protective garden bed.
1. They Share the Same Soil Needs
Rosemary and lavender both prefer sandy or rocky soil that drains quickly.
They hate sitting in water, and their roots rot fast in heavy clay.
So anything you plant with rosemary and lavender must tolerate dry, lean soil too.
2. They Love Full Sun
Both herbs need at least six to eight hours of direct sunlight daily.
Companion plants for rosemary and lavender should be sun-worshippers as well.
If a plant needs shade, it won’t survive next to these two.
3. They Have Similar Watering Schedules
Rosemary and lavender are drought-tolerant once established.
They’d rather be too dry than too wet.
So the plants you grow with rosemary and lavender should thrive on infrequent watering.
Best Plants to Grow With Rosemary and Lavender
Now for the fun part.
Here are the best plants to plant with rosemary and lavender, all of which love the same sunny, dry conditions.
1. Thyme
Thyme is a perfect companion for rosemary and lavender.
It’s a low-growing herb that spreads nicely between the taller rosemary and lavender plants.
Like them, thyme loves full sun and sharp drainage.
Plus, growing thyme with rosemary and lavender gives you a trio of culinary herbs ready for harvest.
2. Oregano
Oregano shares the same Mediterranean roots as rosemary and lavender.
It thrives in poor, rocky soil and loves the heat.
Planting oregano with rosemary and lavender fills the middle layer of your herb bed beautifully.
3. Sage
Sage is another drought-tolerant herb that pairs well with rosemary and lavender.
Its gray-green leaves complement the silvery foliage of both herbs.
Just give sage room to breathe, since it dislikes humidity as much as its neighbors do.
4. Marjoram
Marjoram is closely related to oregano and shares the same love for dry, sunny spots.
It’s a gentle, bushy plant that looks lovely when planted with rosemary and lavender.
Its sweet scent also blends nicely with their aromatic oils.
5. Sedum
If you want ornamental plants to grow with rosemary and lavender, sedum is a fantastic choice.
These succulents store water in their leaves and need almost no extra watering.
Their late-season flowers feed pollinators while rosemary and lavender are between blooms.
6. ornamental grasses
Ornamental grasses like blue fescue or Mexican feather grass are great companions.
They add movement and texture when planted with rosemary and lavender.
These grasses also tolerate drought and poor soil without complaint.
7. Coneflower (Echinacea)
Coneflowers are tough perennials that thrive alongside rosemary and lavender.
They attract bees and butterflies, boosting pollination in your herb garden.
Once established, coneflowers need very little water, just like their companions.
8. Yarrow
Yarrow is another drought-loving perennial that works well with rosemary and lavender.
Its flat flower clusters create a nice contrast against the spiky rosemary leaves and lavender spikes.
Yarrow also repels some garden pests, adding another layer of protection.
9. Russian Sage
Russian sage looks stunning when planted with rosemary and lavender.
Its tall, silvery stems and purple-blue flowers echo the lavender blooms.
Like them, Russian sage loves hot, dry conditions and poor soil.
10. California Lilac
California lilac is a flowering shrub that fits right in with rosemary and lavender.
It’s drought-tolerant, sun-loving, and produces gorgeous blue blossoms in spring.
Planting California lilac with rosemary and lavender creates a shrubby, pollinator-friendly border.
Plants to Avoid With Rosemary and Lavender
Just as important as knowing what to plant with rosemary and lavender is knowing what not to plant.
Avoid moisture-loving plants like mint, basil, and parsley.
These need consistent water and rich soil, which is the opposite of what rosemary and lavender want.
Also skip plants that need shade, like hostas or ferns.
They’ll fry in the same full sun that keeps rosemary and lavender happy.
And don’t plant anything that spreads aggressively, like mint, or it will crowd out your herbs.
So, What to Plant With Rosemary and Lavender?
Rosemary and lavender pair best with drought-tolerant, sun-loving plants like thyme, oregano, sage, sedum, and yarrow.
These companions share the same soil, water, and light needs, so everyone thrives together.
By choosing the right plants to grow with rosemary and lavender, you create a beautiful, low-maintenance garden bed that smells amazing and attracts pollinators.
Just remember to avoid moisture-loving or shade-seeking plants, and give everything plenty of sun and sharp drainage.
With the right companions, your rosemary and lavender will reward you with years of fragrance and beauty.
