You don’t need to live in the desert to think about conserving water. Gardening is challenging enough without worrying whether or not your plants will survive a dry spell. Drought hardy flowers make life a bit easier. Drought tolerant plants have special features that help them survive when rain doesn’t come.

Some of the most reliable drought-hardy flowers are perennials that’ll grow back year after year. They may develop deep roots that can reach water more easily, or grow low to the ground with less surface area exposed to drying wind. Some have thick leaves with a reduced surface area. With so many ways of adapting to dry conditions, there’s no shortage of plants to choose from. Following are some of the easiest drought-tolerant flowers you can grow.

Echinacea

Purple coneflower, Echinacea purpurea, is one of the most popular drought-tolerant plants for numerous reasons. This native North American flower is well adapted to hot summers and cold winters across the continent. The long lasting flowers attract wildlife from early summer through fall, from the butterflies and bees that sip its nectar, to the birds that devour its seedheads.

Although echinacea appreciates consistent soil moisture, once established it only needs irrigation during extended, extreme drought. Purple coneflower is just one of seven native Echinacea species, along with dozens of popular hybrids, that will perform well.

Lavender

Like other members of the mint family, lavender, Lavandula spp., is a rugged plant that thrives where other plants struggle. This native of the Mediterranean region grows best in full sun and well-drained soil, and looks striking in rock gardens and perennial borders.

Whether you plant lavender plants in containers or in your garden, they thrive with low moisture while they look and smell wonderful. Another favorite of pollinators, lavender’s purple or blue flowers add a hint of coolness to the hot summer landscape. And, you can cut and dry the foliage or flowers for tea, sachets, or to add a delicious flavor to homemade ice cream.

Penstemon

Rugged and reliable Beardtongue, or Penstemon spp., thrives in hot, dry locations, including soils that are mostly gravel and sand. In fact they suffer in wet or poorly drained soil. Simply put, you’ll likely never need to water it once it’s established.

These North American natives offer tons of variability in size, bloom color, foliage, and form. They’re an excellent choice for perennial borders, container plantings, and natural areas due to their reputation for deer and rabbit resistance. Some varieties have foliage that remains year round in regions with mild winter weather. Pollinators adore them and you will too.

Rudbeckia

Black-eyed Susans, Rudbeckia spp., are iconic North American wildflowers and perennial garden staples. Their sunny yellow-ray petals and dark centers bring a punch of color to the landscape throughout the summer, while the mature seedheads add structure to the fall and winter garden. Rudbeckia are beloved by birds and bees, and they’re easy to grow in difficult locations.

There’s a Rudbeckia species for virtually every need. The ubiquitous Rudbeckia fulgida remains about knee high and thrives in poor soil. R. hirta cultivars feature soft, fuzzy leaves and large flowers, often with a blush of maroon, orange, or red. The mammoth R. maxima may reach heights well over seven feet.

Salvia

Salvias, commonly called sages, are some of the most useful flowers around. The foliage is typically lightly fragrant and resistant to browsing by deer and rabbits. The blue, purple, red, or white flower spikes are colorful, long lasting, and attractive to pollinators. Use them in wild areas, pollinator gardens, perennial borders, or containers.

There are about 50 species of salvia that are native to North America, many of which are drought tolerant. Choose from popular annual or perennial herbaceous species like blue salvia (S. azurea), autumn sage (S. greggii), black and blue salvia (S. guaranitica), mealycup sage (S. farinacea), Texas sage (S. coccinea), and more.

Hylotelephium

What list of drought-hardy flowers would be complete without succulents? Formerly categorized within the Sedum genus, Hylotelephium encompasses several species of showy-flowered succulents. These plants are thick and fleshy, thornless, and hold up well to heat and drought. In addition to their showy flowers, many of these succulents display colorful, attractive foliage for an extended season of interest. Plus, they attract pollinators.

Plant upright selections like ‘Autumn Fire’ or ‘Purple Emperor’ (H. telephium) among perennials and low shrubs. Trailing types such as ‘Japanese Stonecrop’ (H. sieboldii) or ‘Pink Mongolian Stonecrop’ (H. ewersii) in mixed container plantings, among stepping stones, or as a rock garden groundcover.

For easy maintenance, wise water usage, and season-long garden interest, plant a diverse selection of drought-tolerant flowers. Once they’ve become established, just keep them mulched and divide them every three to five years for a beautiful, healthy, eco-friendly landscape.

How to choose and grow afternoon sun plants that will thrive
Sunlit garden path and flowers

There are many challenges regarding the sun when it comes to gardening. There's too much, then there's too little. For example, some fruit trees thrive in shady backyards — except most trees do require full sunlight. This is why pruning is necessary. And then there are those conditions where too much sun can affect our plants.

Afternoon sun is challenging. Direct sunlight between midday and sunset is the most intense exposure. Although some plants are labeled for "full sun," extended exposure in that hot afternoon sun may be too much — not all of these are suitable as afternoon sun plants. This is especially so if the sunlight is further intensified by a wall or fence that traps and reflects the sun’s heat during the day, then continues to radiate heat after sundown. These tough areas require tough plants.

Knowing how to grow lavender is a useful skill. Lavender is a beautiful and useful flower to add to your garden. It has many different uses, due its beauty, soothing scent, and delicious flavor. Aside from the ways it benefits us directly, lavender also attracts many beneficial insects and is an excellent addition to pollinator gardens.

Lavender is easy to grow indoors and out, making it a great fit for practically any garden or living situation. Want to get started growing your own lavender? Here's everything you need to know to grow it from seed!
Planting lavender
Growing lavender from seed is fairly easy, but requires patience. You can sow lavender seeds directly in the garden, but they germinate much more reliably when started indoors inside a seed tray. Use a light, seed-specific potting mix, and gently cover each seed with a thin layer of soil. Lavender germinates more quickly when it's exposed to sunlight, so don’t cover them entirely. Make sure they’re in a warm location or use a heating mat to keep the seedlings warm.

Zone 9b planting guide: Everything you need to know about nourishing a garden in this warm climate
The best plants to grow in zone 9b and when to grow them
A happy gardener with gloves

From show-stopping roses to hardy agave, zone 9b is home to plants of all stripes, thanks to its warm, sunny conditions. It’s also an ideal environment for a wide range of fruits and veggies, whether you’re partial to hot peppers or sweet cherries. Its hot summers can be challenging, but it’s generally a productive and lush area for thriving plant life. Here’s your zone 9b planting guide so you can nourish a fruitful and beautiful garden in one of the country's warmest areas.
What is a climate zone?
With climate zones on the Plant Hardiness Zone Map, the United States Department of Agriculture divides the country into 13 regions based on average annual minimum temperature ranges. The temperature ranges go from coldest to hottest as we move from zone 1 to 13. Zone 9b, as you may have already guessed, falls on the warmer parts of the map.

Whenever you buy a plant from a store, look for the label that indicates the "plant hardiness zone." If your zone is within that range, the plant is a perennial in your area, meaning it’ll last more than one growing season there. If not, you’ll have an annual on your hands, which means it probably won't survive more than one growing season in your region.
