Pelargoniums should not be confused with hardy geraniums. You might be wondering what makes a geranium different from a pelargonium. Similar to some siblings, they are both members of the same plant family, but they could not be more unlike.
Pelargoniums cannot withstand frost, while hardy geraniums can. Pelargoniums are usually treated as annuals and replanted each year, but true hardy geraniums are perennials that grow back every year. Pelargoniums die in the winter.
Prune your Hardy Geraniums
Your sturdy geraniums will look their best and promote new growth if you prune them properly. By correctly pruning your hardy geraniums after the blooming season, you can encourage repeat blooming. The majority of geraniums can be cut back twice in a single season, which allows them to bloom at least three times.
When to Prune
Your hardy geraniums should be pruned in accordance with the season you are in. Rozanne will require various cuts in the spring, summer, and fall. To maintain your blooms rich and healthy, mark your calendar and adhere to our seasonal trimming recommendations.
What tools you need
Your geraniums may be pruned fairly easily. All you’ll need is the ability to prune, a pair of sharp pruners, your favorite mulch, and your favorite gardening gloves. Watch this video to learn more about pruning strategies in detail.
How to prune
You shouldn’t be concerned that pruning your flower’s back will harm her. The majority of hardy geraniums require trimming to promote new growth and prevent them from encroaching upon other plants.
Trim the plant back to within a few inches of the ground or to about an inch above the main stem once the flowering is completed or you find old growth. Remove any brown stems or yellow leaves after that by going inside.
Soon after trimming, more leaves will start to appear. Some resilient geraniums even have the ability to blossom again. Maintaining correct pruning on your plants encourages new development and keeps them from spilling out throughout your landscape.

Do geraniums grow year-round?
Many perennials are grown exclusively for their flowers due to the lack of interest in their leaves. However, geraniums sometimes have stunning foliage. Many geranium species, such Bigroot geranium and Renards geranium, have leaves that are strongly lobed and dissected. Others are available in hues like gold, burgundy, bronze, gray, and green. A few species also put on a show of fall colors at the end of the growth season, displaying hues of orange, red, and yellow.
Are hardy geraniums contagious?
Among the most common garden perennials are hardy geraniums, sometimes known as cranesbills. And it’s clear why. They require little care and maintenance, are hardy, easy to grow, and tolerant of a variety of environmental factors.
The bloom color ranges from vibrant to subdued violet, blue, pink, magenta, and white hues, and many have appealing veining in a stronger, contrasting hue. Throughout the summer and well into autumn, several types flower nonstop for months at a time, and some even begin blooming as early as late April. When in bloom, the flowers, which are typically rather small, are produced in such great quantities that they almost completely cover the plants.
Numerous species’ hand-like foliage, which exhibits varied quilting, veining, and color blotching, is also very appealing in and of itself. Additionally, because many of the popularly cultivated kinds are low-growing, they make wonderful ground cover plants due to their dense, carpet-like leaf.
They should not be mistaken with the very similarly related pelargoniums, which aren’t and are primarily used as summer bedding plants, as they are cold- and frost-hardy.
Cultivation
There are kinds that can thrive in direct sunlight, light shade, and even pretty deep shadow. They generally thrive in early morning and late afternoon sun, while some, like Geranium sanguineum and Geranium pratense and their variants, grow well in full light as long as the soil has enough moisture.
Hardy geranium varieties
There is at least one hardy geranium for every garden, every gardener, and every circumstance as there are about 70 species and 700 types to choose from!
Here are the top 10 items that the Royal Horticultural Society suggests:
- Ann Folkard, geranium
- (Cinereum Group) Ballerina named Geranium
- Clarkei Kashmir White Geranium
- Red geraniums
- Theodora Mavis Simpson
- Ingersoll Orion
- The Mrs. Kendall Clark geranium
- Wageningen’s Geranium x oxonianum
- Renardii geranium
- Jolly Bee and Geranium Rozanne (Gerwat)
Planting hardy geraniums
Hardy geraniums can be planted at any time of year, but planting in the fall or winter will ensure that the plants take root effectively and provide an abundance of flowers in their first season. For planting from late autumn to late winter, mail-order vendors often offer bare-rooted plants.
Make a hole that is sufficiently large to readily fit the rootball. Fork in a layer of organic material, such as compost or planting compost, at the bottom of the hole.
Place the rootball in the planting hole, adjusting the planting depth until the rootball’s top is level with the soil and the rootball is planted at the same depth as it was growing initially.
Fill the planting hole with the excavated soil after adding more organic matter to it. To maintain soil moisture and aid in weed control, thoroughly water the area around the tree, then sprinkle a granular general feed over the surrounding soil. Finally, put a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or bark chips around the tree’s root area.
How to care for hardy geraniums
The majority of hardy geraniums are undemanding, low-maintenance plants.
When the weather is dry during the first year, water thoroughly. To maintain healthy plant growth in succeeding years, watering may be required during extended dry spells.
Late spring mulching around the plants will assist retain soil moisture and control weed growth.
Plants may start to seem messy with sloppy growth after the first early flush of blossoms has faded. After the initial flowering, the majority benefit from a trim to freshen the foliage and promote more blooms. To get rid of the outdated, messy growth, just cut the plants with a pair of shears or secateurs, or more forcefully if necessary, to a height of 5-7.5cm (2-3in) above the ground.
Then feed them with a liquid plant food to promote new growth and additional flowering flushes. After each flowering, pruning and fertilizing can be done again to extend the flowering season of many kinds well into the fall.
With the arrival of colder weather in late autumn, most geraniums’ foliage will start to fade. If you trim the plants’ leftover stems and leaves, they’ll grow new, fresh growth the following spring.
Over time, hardy geranium plants expand, spread, and form enormous clumps. These can be chopped into halves or quarters with a sharp spade. This can be done in the spring when they begin to grow or in the autumn. Every three to five years, divide them to maintain good growth and flowering.
What is the lifespan of hardy geraniums?
Nowadays, it seems that everyone is interested in discovering the key to longevity. How can we lengthen our lives while maintaining the health and vitality of our bodies? The same information is sought after by gardeners for their prized plants. How long does a geranium live? Rozanne and other hardy geraniums could possibly survive forever. What can we do to ensure that they have long and healthy lives as their gardeners?
Even our lovely Rozanne and other real geraniums don’t survive forever. With proper care and some luck, you can help maximize a healthy lifespan, giving your plants a long, happy life. Some amateur gardeners have even reported their lovely geraniums lasting generationsup to 40 years or longer!
How can I save my geraniums for the following season?
Geraniums have the advantage of easily entering dormancy, allowing for storage in a manner akin to that of sensitive bulbs. This method of storing geraniums for the winter entails digging the plant up in the fall and carefully removing the soil from the roots. The roots should not be spotless, just clear of dirt clumps.
In a room with a constant temperature of roughly 50 degrees Fahrenheit, such as your garage or basement, hang the plants upside down (10 C.). Rehang the geranium plant after soaking the roots in water for an hour once a month. All of the leaves on the geranium will fall off, but the stems will still be alive. Replant the dormant geraniums in the ground in the spring, and they will come to life.
Do you prune geraniums that are hardy in the winter?
Hardy geraniums can be grown in the sun or the shade in moist but well-drained soil. After flowering, prune back the plant to promote a second flush of blooms. Hardy geraniums wither in the fall and reappear in the spring. Plants will continue to grow well for several years if they are mulched annually with leaf mold, well-rotted compost, or horse manure.
Huge, vivid violet blue, saucer-shaped flowers are held above mounds of deep green foliage that has a faint chartreuse marbling and prominent white eyes. One of the garden’s perennials with the longest bloom times is the geranium “Rozanne.” Given that its flowers are sterile, it is an impressively free-flowering variety that continues to bloom from late spring until mid-fall.
Give this perennial lots of freedom to expand widely. One healthy plant can cover an area of 2-3 square feet in a single season. When combined with yellow or chartreuse flowers or foliage, it looks very lovely. the Rozanne and FriendsTM series.
Hardy geraniums make excellent filler plants for both home and commercial landscapes. They complement the majority of other perennials well and provide constant color all year long.
Are your hardy geraniums deadheaded?
Once established, hardy geraniums require minimal maintenance. After blooming, the plants might become a little scraggly, and deadheading is challenging due of the abundance of thin stems. Restoring the plants to their basal growth will enhance their appearance and promote reblooming. Within a few weeks, the plants recover.

Perennial geraniums live how long?
You may divide geraniums into two primary groups. There are real geraniums, also known as cranesbill and hardy geraniums. They are frequently mistaken for common or scented geraniums, which belong to the related but distinct genus Pelargoniums. Compared to true geraniums, these offer a considerably more impressive flower display, but they are more difficult to maintain over the winter.
Only USDA zones 10 and 11 are suitable for growing pelargoniums, which are native to South Africa. They are typically only grown as annuals in most countries, despite the fact that they can live for many years in warm regions. They may also be raised in containers and brought indoors to overwinter. As long as it doesn’t get too cold, the common geranium can live for many years.
On the other hand, true geraniums can be cultivated as perennials in a considerably wider range of conditions because they are far more cold hardy. For the most part, USDA zones 5 through 8 are winter-hardy. Some types can withstand the hotter summers in zone 9, while others can endure winters that are as chilly as those in zone 3, at least for the roots.
As long as it is properly cared for, geraniums can live for many years. Additionally, they are easily overwintered. Some other kinds, like the biennial Geranium maderense, only live for two years but can withstand most winters.
In order to answer the question “how long do geraniums live,” it is important to consider both your location and the sort of geranium plant you own.
Do I need to trim back my perennial geraniums?
reducing after blossoming After flowering, early-flowering perennials like geraniums and delphiniums are pruned to almost ground level to promote new growth and late-summer blooming. Then, in the fall or spring, these are again pruned.
Can geraniums survive the cold outside?
Knowing how to overwinter geraniums is very useful for gardeners since it can help them save money and extend the life of particular varieties they enjoy.
Pelargoniums, sometimes known as geraniums, are mainstays of the summer garden. Geraniums are ideal for adding cheer and long-lasting color to hanging baskets, containers, and borders since they come in a variety of colors and flower continually as long as they are deadheaded.
However, when making your job list, you might consider including them as one of your winter garden ideas.
When growing frost-sensitive plants, planning a winter garden is crucial. Geraniums are perennial plants that put on a long display, but they are frost tender, which means they won’t survive harsh winters. If you are interested in cultivating geraniums, you must learn how to overwinter them.
Geraniums are South African natives that thrive in the heat and can withstand periods of drought with little water.
Pelargoniums, sometimes known as geraniums, may live in USDA zones 7 to temperatures of -12oF (0oC) if they are sheltered. They are hardy in climates between 20oF and 50oF in zones 9 through 12. They need to be sheltered in these conditions because, while they can withstand brief frosts (temperatures slightly below freezing), they cannot withstand prolonged exposure.
The Pelargonium genus contains a wide range of cultivars, all of which are categorized as delicate perennials. According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “this means that they are not cold hardy as the majority of the founding species come from the warmer climbs of the Southern Hemisphere.
Perennial plants are able to flourish for a number of years, however in the UK this would mean that they would also need to be sheltered from winter wet and damp in addition to frost.
Geraniums can be cared for like annuals by being dug out in the fall, composted, and then replaced with fresh plants the following year. The appropriate care and attention, however, will enable you to winterize geraniums, keeping them alive throughout the winter so they can bloom once more the following year.
According to David Taylor, vice chairman of the UK Pelargonium and Geranium Society, “Keen enthusiasts keep their pelargoniums in growth during the winter and continue to feed and water but a few key points can be undertaken by anyone to keep your pelargoniums (geraniums) alive throughout the winter” (opens in new tab).
Pelargoniums are known as geraniums, but these plants are not the same as hardy geraniums or cranesbill, which are a different kind of plant and don’t need to be overwintered.
