Which Plants Grow in Alkaline Soil


If you have alkaline soil in your garden, you might be wondering what plants are best suited for this type of environment. Alkaline soil, also known as sweet soil, has a pH level above 7, which means it has a higher concentration of alkaline or basic elements. While most plants prefer neutral or slightly acidic soil, there are still many options available for those with alkaline soil. In this article, we will explore some plants that thrive in alkaline soil and provide tips on how to create the best growing conditions for them.

Plants that Thrive in Alkaline Soil


Lavender is a beautiful flowering plant that not only adds color and fragrance to your garden but also thrives in alkaline soil. It loves the dry and rocky conditions typically found in alkaline soil and requires minimal water once established.


Yarrow is a hardy perennial plant that is well-suited for alkaline soil. It produces clusters of small flowers in various colors and can tolerate drought conditions. Yarrow is also known for attracting butterflies and other pollinators to your garden.

Russian Sage

Another great option for alkaline soil is Russian sage. This perennial plant features silver-gray leaves and produces beautiful lavender-blue flowers. It is drought-tolerant, deer-resistant, and attracts bees and butterflies.


Agastache, also known as hyssop or hummingbird mint, is a vibrant and fragrant plant that thrives in alkaline soil. It produces spikes of tubular flowers in shades of purple, pink, and orange, which attract hummingbirds and butterflies to your garden.


Salvia is a diverse genus of plants that includes many species suitable for alkaline soil. These plants are known for their vibrant flowers in various colors, including red, purple, blue, and white. Salvia is also a favorite among pollinators.

Creating the Best Growing Conditions

While these plants are well-suited for alkaline soil, it is still important to create the best growing conditions for them. Here are some tips:

Soil Amendment

If your soil is highly alkaline, you can amend it by adding organic matter such as compost or well-rotted manure. This will help improve the soil structure and provide essential nutrients for plant growth.

Proper Watering

Ensure that you water your plants deeply and infrequently rather than shallowly and frequently. This encourages deep root growth and helps the plants tolerate dry conditions.


Apply a layer of organic mulch around your plants to help conserve moisture, suppress weed growth, and regulate soil temperature. This is especially important in alkaline soil, which tends to dry out quickly.


Having alkaline soil doesn’t mean you have to limit your plant choices. There are plenty of beautiful and hardy plants that thrive in alkaline conditions. By selecting the right plants and providing them with the best growing conditions, you can create a vibrant and flourishing garden.
