Why Our Ancestors Planted These Flowers During Droughts | Garden Folklore & Drought-Tolerant Plants

Have you ever wondered why certain flowers seem to thrive no matter how hot or dry the summer becomes? Long before garden centres, irrigation systems and weather forecasts, our ancestors had to depend on plants that could survive naturally. Every flower they chose had to earn its place. Welcome to the Bear in the Garden channel. Today we're exploring the fascinating history, folklore and practical wisdom behind drought tolerant plants and discovering why many of these centuries-old favourites are just as valuable in today's gardens. For much of history, drought wasn't simply inconvenient. It could threaten food supplies, livestock and entire communities. Gardeners couldn't simply turn on a tap. Water had to be carried by hand from wells, collected in barrels or saved from precious rainfall. Every drop mattered. That meant choosing plants that could cope with difficult conditions. Many of those same plants are still popular today, not because they're fashionable but because they have quietly proven themselves for hundreds of years. Let's begin with one of the most recognisable, lavender. Native to sunny Mediterranean, lavender evolved in dry rocky soils where rainfall could be scarce for months. Its narrow silver grey leaves are coated with tiny hairs and aromatic oils which help reduce the moisture loss. Medieval monasteries grew lavender for medicine, fragrance and household use, while folklore suggested it brought calm, purity and protection to the home. Even today, lavender remains one of the finest plants for bees, butterflies and drought-prone borders. Next comes house leek, also known by its botanical name Sempervivum, meaning always living. Its fleshy leaves act like tiny water tanks, storing moisture for long dry spells. Across Britain and Europe, people planted house leeks on rooftops, believing they protected homes from lightning, storms and even fire. Whilst science doesn't support those magical claims, their ability to survive on roofs and stone walls certainly made them appear almost indestructible. Yarrow was another trusted companion. With its finely divided leaves and deep reaching roots, yarrow can continue flowering when many other plants begin to fail. It was valued both as a medicinal herb and as a symbol of healing and courage. Some traditions even claimed yarrow could predict the weather or reveal future love, adding another layer of mystery to this remarkable resilient plant. Then there are the familiar culinary herbs, sage, thyme and rosemary. These Mediterranean natives naturally evolved where summers are hot and rainfall is limited. Thick leaves, aromatic oils and compact growth help them conserve moisture. Medieval gardeners treasured them not only for cooking but for medicine and symbolism. Sage represented wisdom, rosemary was linked with remembrance and loyalty, while thyme was believed to inspire courage. Verbena has an equally rich story. In ancient Rome it was regarded as a sacred plant, while later folklore associated with blessings and protection and good fortune. Today gardeners appreciate for something more practical, long-lasting flowers that attract pollinators while coping well with the dry conditions once they're established. And finally we come to sedums, now often known as stone crops. These remarkable succulents store water inside their fleshy leaves allowing them to flourish where other plants struggle. Their late season flowers provide an important source of nectar for bees and butterflies, just when many other blooms are fading, proving that drought tolerant doesn't have to mean we work wildlife is less. But the plants themselves are only part of the story. People search for signs that a dry summer was on the way. When a drought could mean failed harvests and hungry families, every unusual change in nature seemed important. And across Britain, one of the best known pieces of weather folklore, oak before ash, we're in for a splash. Ash before oak, we're in for a soak. People believe that order in which oak and ash trees came into leaf could predict the kind of summer ahead. The saying survives because generations of gardeners carefully observed the natural world. Another widespread belief was an unusually heavy crop of berries or acorns meant a difficult year was coming. Some thought nature was preparing birds and wildlife for hard times ahead, including long dry spells. But modern ecology tells us these bumper crops are more closely linked to the previous year's growing conditions than to the still to come. But it's easy to understand why people made that connection. In farming communities, the behavior of animals was watched just as closely. Bees staying unusually close to the hive, swallows flying differently, and ants building especially tall nests were all taken as possible signs that the weather was about to change. Some of these observations may reflect short-term changes in temperature, humidity, or air pressure, but they can't predict a drought weeks or months in advance. Perhaps the most enduring lesson from these old traditions isn't that they could control the weather, but they could encourage people to pay close attention to the landscape around them. They noticed when birds nested earlier than usual, when wild flowers bloomed ahead of schedule, or when streams began to run lower than expected. Today we have weather models and rainfall records and climate data, but there's still something valuable in slowing down and observing our gardens. The folklore may not predict drought with scientific accuracy, yet it reminds us that successful gardeners have always learned by watching nature carefully season after season. So what can modern gardeners learn from all this? Our ancestors didn't fight against nature, they worked with it. Instead of trying to force thirsty plants to survive in dry soils, they selected species already adapted to local conditions. They improved the soil with organic matter, mulch to retain moisture, and collected rainfall wherever possible, and accepted that some plants were simply best suited to hot summers than others. Today with warmer drier summers becoming more common across parts of the UK, those lessons feel more relevant than ever. Choosing resilient plants can reduce watering, support pollinators, and create gardens that remain colourful even during prolonged dry spells. Of course not every piece of folklore was rooted in fact. Lavender won't magically protect your home and house leaks won't stop lightning, but behind many of these old beliefs lies generations of careful observations. These were the plants that survived when others failed, becoming symbols of hope because people witnessed their remarkable resilience year after year. And perhaps that's why these traditional favourites have never truly gone out of fashion. They connect us not only with nature but also with countless generations of gardeners who observed, experimented, and passed on their knowledge through the stories as well as their experience.
