Hardy geraniums, however, generally favor well-drained, somewhat rich soil. The majority thrive in either full sun or partial shade, however they prefer to be reasonably dry as they can develop mildew if kept wet. Hardy geraniums should be planted with their crowns at or just above ground level.
Where should hardy geraniums be planted?
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

- 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.
Hardy geraniums prefer shade or the sun.
While the tiny alpine varieties do best in full sun, most hardy geraniums do best in mild shade. Geraniums that are hardy may grow in any type of soil, and some, like Geranium sylvaticum and its cultivars, can survive in extremely dry conditions.
Hardy geraniums are excellent self-seeders and frequently grow in minuscule paving cracks, demonstrating their hardiness.
How to grow hardy geraniums
Hardy geraniums are frequently purchased in pots, but they can also be acquired bare-root online. When purchasing bare-root geraniums, pot them up as soon as they come and plant them outside once they have grown for a few weeks. Unless the soil is extremely bad, there is no need to improve it.
Can tough geraniums tolerate shade?
Unlike the annual geraniums (which are actually pelargoniums) we buy for porch pots or bedding plants, hardy geranium is a perennial. Hardy geraniums grow in low mounds and bloom in white, red, purple, pink, or blue from spring through October. Some cultivars do perfectly in full shadow, and they will still thrive in part shade. Hardy geraniums also survive dry soil, which is a benefit when growing them under trees. In zones four through eight, they are resilient.
What can I grow beside hardy geraniums?
Late spring to early summer, with some flowers reblooming all summer long in hues including white, blue, and pink.
Actually, geraniums aren’t geraniums. The annual flower Pelargonium is what most gardeners mean by geranium. I discuss them in the annuals chapter. In New England, true geraniums are hardy perennials with low growth and free flowering that come in hues like blue, white, and pink. Due to the seedpod’s resemblance to the bill of this bird, they are also known as cranesbill geraniums. The flowers develop above the lobed foliage and bloom intermittently throughout the summer. Deadhead the plant on a regular basis. This rambunctious plant extends out a few feet, but pruning and division control it. Bees and butterflies are drawn to the tiny, cup-shaped flowers.
Grow resilient geraniums all around New England. After all risk of frost has past, plant locally acquired transplants or divisions from a friend’s garden in the spring till early October. Although they will still bloom in partial shade and on clay soils, they grow and bloom best in full sun on well-drained, compost-amended soil. In beds, leave a foot between plants.
Each spring, plant hardy geraniums with a layer of compost and lots of water and fertilizer. Mulch around plant bases to prevent weed growth and maintain moisture in the soil.
If deadheaded and pruned after the initial blooming time, hardy geraniums will produce flowers again. If plants are divided every three to four years, they appear neater and blossom better. Dig up the cluster in the spring and separate out 1-foot-diameter portions for replanting or sharing. One of the most low-maintenance perennial plants you can cultivate in your garden is a hardy geranium. However, they are susceptible to powdery mildew in partial shade or during humid summers. To lessen the prevalence of this illness, keep plants clipped, spaced far apart, and clear away the fallen leaves in the fall.
In the perennial garden, hardy geraniums make excellent filler plants. They can fill in next to plants that have done flowering, like peonies and iris, or they can enhance other summer blooming plants, like roses, daylilies, and coreopsis. This is because they sprawl and flower in the summer. Keep hardy geranium trimmed so they don’t look too untidy if you plant them in the front of your flower bed. More trailing plants can be planted along a wall to cascade over the top.
My preferred hardy geranium variety is “Rozanne. This cultivar bears violet-blue flowers on a 2-foot-tall plant.” “Ann Folkard is a magenta colored flower kind that barely grows 8 inches tall and is ideal in a rock garden or along a wall. Johnson’s Blue is another similarly small blue blooming variation. White blooms grow on 12-inch-tall plants in the album.
How well do hardy geraniums grow in pots?
Can hardy geraniums be grown in containers? This query has recently come up from new gardeners.
Without a doubt, the response is YES! You can definitely plant your favorite hardy geraniums—say let’s Geranium Rozanne—in your favorite garden containers. Rozanne enjoys dripping from window boxes and hanging plants. She also enjoys leaning over the edge of large planters. As it turns out, container gardening is a great way to highlight Rozanne’s best qualities. Here are some justifications on why this may be the best option for you.
Hardy Geraniums vs. Pelargoniums
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.

Geraniums can they get too much sun?
Are you unsure of where to plant your brand-new geraniums? Do they require full sunlight or perhaps a shaded area? Where to arrange young plants so they receive precisely the right amount of sunlight while avoiding overexposure is one of the major challenges a gardener encounters. We done the study and have an answer for you regarding your new geraniums.
Four to six hours of direct sunlight every day, plus more if the light is filtered, is what geranium plants need to thrive. They can, however, endure in less sunny environments.
There are a few more things we need to talk about before you go outdoors to sow your seeds. Continue reading to learn more about this topic and to learn which geranium varieties thrive in shadow.
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.
