9 Thyme plants for your dry garden
When facing extreme weather conditions, thyme plants are an excellent choice. If you’re seeking resilient, drought-tolerant shrubs for a low-maintenance dry garden, you’ve found the perfect guide. Explore our selection of nine thyme species, each with unique sizes and colours, to find the ideal fit for your garden.
I will describe each Thyme plant with plenty of images so you can easily see what they look like and compare them in terms of size, hardiness, drought tolerance and blooming times.
Let’s walk through each plant and then compare them so that you can select the right ones for your garden.
Types of Thyme plants
Thyme plants are mostly native to the Mediterranean basin, adapted to grow in full sun and poor, well-drained soils. This makes them an ideal choice for a Mediterranean garden style.
They are drought-tolerant, hardy and can tolerate most types of soils, from acid to mildly alkaline.
These robust evergreen shrubs can be very diverse:
- Foliage can vary from silver to dark green.
- Flowers can come in shades of pink, violet, blue and white,
- Habit can vary from upright to mounding to creeping.
- Size can range from very small (1 – 5 cm / 0.4 – 2 in) to medium (30 – 40 cm / 12 – 15 in).
I am sure you will find one that suits your personal taste, literally, as they can also be used as a condiment in your cooking.

What do Thyme plants look like?
Thyme inflorescence has a globose or spike form with whorls of tiny flowers and bracts. The lowest whorls are often separated.
The flower colour can be pink, violet, purple, blue, or white.
The leaves are quite varied. They are entire but can have different shapes, from linear to lanceolate to oval to broadly elliptic. Their colour can range from grey-green to mid-green to dark green.
Stems are squared and become more rounded and woody as they age.
The size and habit are diverse, from spreading to mounding to upright. The size is small (1-5 cm / 0.4-2 in) to medium (30-40cm / 12-15in).
In the chart, you may see how the different parts of the selected Thymes compare.
Height and Width of Thyme plants
The height and width of Thyme plants can be varied from shorter spreading types, such as Thymus serpyllum and T. ciliatus, to slightly taller ones with a more mounding shape, like T. citrioduous, T. vulgaris, T. capitatus, T. zygis, T. pulegiodes, and T. camphoratus and taller still with an upright shape like T. mastichina. However, the plant size will vary based on the weather, sun exposure, soil and fertilization. So you may end up with different sizes than those shown in the chart.
Which is the tallest Thyme?
The size of any plant can vary based on many factors, such as soil, weather, watering and so on. However, the tallest Thyme species is usually Thymus mastichina, with an upright habit whose height can reach 40 cm (1.3 ft). Because there are so many different varieties, including hybrids and cultivars, you may find even taller ones among these.
Thymes bloom times
Thyme plants will bloom around spring and summer. Some types start a little earlier than others, and the duration of the bloom time also varies a little.
Many factors affect flowering, such as temperature, sunlight availability, and soil fertility; slight variations may depend on your garden´s environment.
But generally, the bloom times for the 9 selected species in this article are shown on the chart.
Which is the hardiest Thyme?
The hardiest thymes are Thymus vulgaris (Common Thyme) and Thymus serpyllum (Breckland Thyme) which can tolerate temperatures down to -15ºC (5ºF).
However, most Thymes will be quite hardy if you give them the right growing conditions, such as well-drained soil and little or no fertilization. They will only suffer in very wet and cold winters.
In this article, I have selected the most cold-hardy types because I always try to choose the plants better adapted to weather extremes that we face with climate change.
Nevertheless, some Thymes are naturally tougher than others. Depending on your climate, you may choose the best ones for your garden based on the hardiness chart shown here.
Which is the most drought-tolerant Thyme?
Thymes are amazingly tough plants that can survive hot and dry weather for long periods and remain evergreen with showy blooms.
Although Thymes are drought-tolerant, some are incredibly drought-resistant, such as Mastic time, while others are only moderately drought-tolerant, like Breckland Thyme and Moroccan Wild Thyme. The rest are somewhere between 3 to 4 months of drought resistance.
The chart uses the drought-tolerance code defined by Olivier Filippi (https://jardin-sec.com/), which I find very useful and have found to be correct based on my own experience.
Which Thyme is the most fragrant?
The different thyme species have varying fragrance intensities. The most fragrant species I have found is Mastic thyme (Thymus mastichina). You can smell the lovely and intense aroma just by going near it. You don´t even need to touch it. This is the best thyme for aromatic gardens.
Which is the best Thyme for your garden?
This is the question that I hope to answer with all the information provided in this article. The best thyme will be different for different people and different environments.
While you cannot change some conditions, such as the size and hardiness of the plant, others you can adjust, like soil and watering.
