Watering can become a chore in hot summer weather, but some garden plants are better equipped for longer periods of heat and dry soil. Deep roots, fleshy growth and silvery or textured leaves help some plants cope when rainfall is low.
Agapanthus, yarrow, sea holly, lavender and lamb’s ear are plants that can handle dry conditions once established. They also bring flowers, foliage and structure to borders without turning a drought-resistant garden into a bed of succulents.
Lavender can take up sunny spots that other plants struggle with
Lavender fills the narrow planting beds between the steps, with spikes of purple flowers extending over the stone edges. Location reflects the conditions lavender favors: open exposure, drainage around the roots and room for stems to spread over a hard surface.
Lavender comes from the Mediterranean region and can tolerate dry periods once established. Palframand includes rosemary, oregano, and thyme because those herbs adapt to the sun, although plants in containers still need water because pots dry out faster than garden soil.
Yarrow brings flowers to dry, open borders
Yellow and pink yarrow flowers grow among grasses and other perennials, with large rocks breaking up the plantings. Instead of relying on dense green foliage, the border incorporates fine leaves, flower heads, stones and open spaces between plants.
Achillea, or yarrow, favors full sun and well-draining soil. Its flat flower clusters also make it useful when a drought-tolerant garden needs more than grasses, succulents and silvery foliage.
Yarrow works with ornamental grasses
Pink yarrow grows from clumps of beautiful ornamental grasses, while tall perennials add height to beds. Grass yarrow occupies most of the ground without hiding the flowers, creating a planting border that does not depend on shrubs or clipped hedges for structure.
This type of combination suits a dry garden because plants with different forms can fill the border without the need for blocks like a green lawn. Yarrow provides broad flower heads while grasses provide movement and cover around the stems.
Red yarrow adds strong color without large flowers
This mixed border features red and rust-colored yarrow above blue flowers and fine green foliage. Each yarrow stem has a cluster made up of many small flowers, so the plant produces broad areas of color without producing large blooms.
According to Palframand, yarrow can rebloom after its first display when it is cut back. It lends a perennial role in the summer border while its sun and passive soil preferences make it a strong choice for gardens where water use is a concern.
Agapanthus can grow alongside larger foliage plants
Clusters of white agapanthus flowers stand among large fern fronds beside a winding gravel path. Their tall stems lift the flowers above the lower foliage, while the narrow leaves form clusters at ground level.
Agapanthus stores water in fleshy roots and grows well in heat, but drainage matters. Palframand recommends it for warm patios and sunny areas and notes that the plant also does well when its roots have limited space, making pots another option.
Lamb’s ear uses its leaves to cope with dry conditions
A flock of silver-green sheep’s wool ears sits beside a gray gravel path, bordered by lime foliage, groundcover and ornamental grasses. Its thick, soft leaves stand out from the lush greenery around it, giving the border contrast without relying on flowers.
Lamb’s ear is not one of Palframand’s five main choices, but it does name it among plants adapted to heat and drought. Its pale, hairy leaves are found in many plants suited to sunny, dry sites, making them useful when aiming to create a drought-resistant garden around foliage as well as flowers.
Agapanthus dominates warm, sunny garden beds
Blue agapanthus flowers grow from tall ornamental grasses, their round flower clusters held high above the narrow foliage that surrounds them. The combination shows how agapanthus can fit into a planting border without needing open ground around each plant.
A native of South Africa, agapanthus can handle heat and dry periods once established, while wet soil around the roots can cause problems. Palframond recommends it for warm patios and sunny areas and notes that its preference for stunted roots also makes it suitable for containers.
Sea holly brings blue flowers to dry borders
Blue sea holly is at the front of this mixed border, where its spiky flower heads and pale stems contrast with purple flowers, grasses, ferns, and green foliage. Plants add a distinct shape to a bed without relying on broad leaves or large flowers.
Eryngium, or sea holly, favors full sun and soil with strong drainage, including sandy, gravelly and loamy soils. Its deep root system helps it withstand dry conditions, while the blue flower heads provide a summer food source for bees and other pollinators.
Drought tolerance does not mean that the plant can go without water from the day it enters the soil. New plants need water when the roots are established, and the container dries out before the same plant grows in garden soil. For established plantings, choosing species suited to sun and dry soil can reduce the amount of water the garden needs during hot summer periods.
