A variety of colors can be seen in the leaves and flowers of perennial geraniums. Pink, purple, red, burgundy, blue, and white are among the flower’s colorations. Veins in blossoms are frequently darker in tone, giving petals a whisker look. The blooming season for many hardy geraniums runs from spring to July. This group includes geranium ‘Max Frei,’ a kind of bloody cranesbill (Geranium sanguineum), and wild geranium (Geranium maculatum). Some cultivars, such as Rozanne or Geranium ‘Johnson’s Blue,’ bloom continuously.
The split leaves of hardy geranium plants add a wonderful texture to landscape designs. Green, burgundy, gold, or almost-black leaves, like those of the cranesbill geranium variety “Dark Reiter,” are possible leaf hues (above). Some geraniums, like the natural wildflower Geranium maculatum, have vibrantly colored leaves in the fall that range from orange, gold, and crimson.
Hardy geraniums come in a variety of sizes, from 6 inches to more of a knee-high, 18-inch plant. While some have stems that spread and creep their way across the garden over the growing season, others produce neat tufts in a planting bed. From Zones 5 to 9, perennial geraniums are typically hardy.
What distinguishes my geraniums as perennial or annual?
Are geraniums perennial or annual plants? Are you one of those customers at the garden center who has to pause and clarify the difference between an annual and a perennial? Unless gardening is our one and only true love, the truth is that we have all likely experienced it at some point.
A seasonal plant dies after going through one life cycle. A perennial plant endures for at least two years. Depending on where and how they are grown, geraniums can be either annuals or perennials.
The Latin term for geranium is pelargonium. These plants are typically grown as annuals since they cannot endure cold. However, they can be grown as perennials with a few simple techniques. In the following sections of this post, let us share a few of those tips with you.
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.
How are perennial geraniums cared for?
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.
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.
What kind of plant is an annual geranium?
Annual geraniums are attractive flowering plants for both indoor and outdoor spaces. This plant is perfect for home landscaping because of the range of flower hues, leaf forms, colors, and growing behaviors. These adaptable plants grow beautifully in containers, hanging baskets, and as annual bedding plants. Since they belong to the genus Pelargonium, annual geraniums are not “genuine” geraniums. Perennial plants in the genus Geranium are true geraniums.
Geranium x hortulanum, often known as common garden or zonal geraniums, are frequently sold as bedding or container plants. On its leaves, many feature prominent, black bands or markings (also known as zones). Flowers can be solitary or double and are produced in spectacular, huge clusters. Red, burgundy, lavender, pink, salmon, orange, white, and bicolor are some of the flower hues.
Geranium peltatum, often known as the ivy geranium, has leaves with an ivy form and a more vine-like or trailing growth habit. Flowers come in hues resembling those of the typical garden geranium and can be single or double. In window boxes and hanging baskets, plants thrive. Ivy geraniums benefit from some afternoon shade because they are less heat-tolerant than regular garden geraniums.
There are numerous species, varieties, and Pelargonium hybrids that make up scented geraniums. The sizes, forms, and colors of a plant’s leaves vary greatly. As implied by the name, leaves typically have scents of lemon, rose, peppermint, nutmeg, apple, oak, and other plants. Geraniums with a fragrant scent make wonderful container plants. Less spectacular than most other geraniums, the flowers are often white, pink, or lavender. One variety of scented geranium is the extensively advertised “mosquito geranium.” The leaves exude a citronella scent when they are stroked, brushed, or crushed. Plants in containers on a patio or deck do not deter mosquitoes as the citronella oils are only produced when touched.
The cool-season annual geranium is the Martha Washington or regal geranium (Pelargonium x domesticum). Large, ruffled flowers in the hues white, pink, red, purple, yellow, burgundy, and bicolor are characteristic of this species. These geraniums are typically only offered as container plants in the late winter or early spring because they do best in chilly climates. They make great houseplants for a few weeks, but once flowering is through, they are usually thrown away.
In some parts of the US, fancy-leaf or variegated garaniums are growing in popularity. They are variations or hybrids of geraniums from the common or zonal group, which are distinguished by their vibrant, multicolored foliage. These gorgeous plants make excellent indoor and outdoor container plants because of their combinations of green, yellow, white, red, burgundy, bronze, or coral foliage. Several have fragrant leaves. Although the blooms on the plants are smaller and less flamboyant than the ordinary garden geraniums, they might be red, pink, lavender, or white.
The best time to plant annual geraniums outdoors is after the risk of frost has passed. In much of Iowa, this is often mid- to late-May. The majority of geraniums favor full light, soil that is moist, fertile, and well-drained (at least 6 hours of direct sun per day). In places with less than six hours of sunlight per day, flowering will be limited.
both fertilizing and water
In hot, dry weather, geraniums growing in containers need frequent watering, often twice or three times per week. In ground beds and borders, geraniums need about an inch of rain per week. During dry conditions, water once per week for the greatest results. Avoid soaking the leaves when watering as this could encourage the spread of disease. Nearly all geraniums, especially those in containers, benefit from frequent fertilizer. During the summer, it’s best to apply a diluted solution of a water-soluble fertilizer once or twice a month.
promoting the growth of flowers
Deadheading geraniums regularly is beneficial (removal of spent blooms). By avoiding seed formation, deadheading encourages the growth of more flowers. It also enhances the way that plants look overall.
Winterizing possibilities
As container houseplants, geraniums can be kept indoors throughout the winter. They require constant watering, comfortable temperatures, and bright light near a window. The common garden geranium can also be overwintered by being stored as bare-root plants. Before the first frost in the fall, remove plants from ground beds or containers, gently shake off the soil from the roots, and place the bare-root plants in a sizable paper grocery bag. For the most of the winter, keep the geraniums in a dark, chilly environment (about 50–55 degrees F). Remove the dead stem tips in March and plant the remaining stems in containers after pruning down to firm, green stem tissue. Place the containers in a light-filled window and water as necessary. In May, you can put flowers outside.
How do you maintain the flowering of perennial geraniums?
How to Increase Hardy Geranium Blooms
- Give the Right Lighting. Make sure your blooms are receiving enough sunlight.
- Maintain Soil Moistness. Keep the soil damp but not soggy.
- Detach any leggy growth. Midsummer is the time to prune the plants.
- Give Your Plants Food. To promote blooming, apply a fertilizer strong in potash.
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.

What kind of plants are hardy geraniums?
Hardy geraniums are a group of flowering perennials that include many cultivars of the genus Geranium’s several species and hybrids. They go by the names real geraniums, perennial geraniums, and wild geraniums collectively. Other popular names for geraniums are wild geranium, crimson geranium, and cranesbill geranium (Geraniummacrorrhizum) (Geraniummaculatum). Many garden cultivars are the offspring of hybrids created by combining different species.
Tip
Beginners frequently mistake these perennial kinds for an other kind of plant that goes by the name of geranium. They may also be known as zonal geraniums, although the classic annual “geraniums” you see in deck planters and cemetery urns are actually Pelargonium x hortorum hybrids.
The Geranium genus contains a wide range of species, but the majority of those that are grown commercially are low-growing, thick carpet-like plants with flower stalks that poke and weave among other plants. The plant’s surface is covered in flowers that are various colours of white, pink, magenta, purple, and blue. The tiny, cup-shaped flowers, which are about an inch in diameter, draw a lot of butterflies and bees.
Depending on the variety, hardy geraniums can be used in a variety of ways in the landscape. While some types make excellent ground cover or rock garden plants, others are perfect for forest gardens and settings with some shade. Some hardy geraniums only bloom once, generally early in the growing season, while the majority begin to bloom in the middle of the summer and continue to bloom occasionally all through the growing season. Newer cultivars, including “Rozanne,” bloom continuously all summer long.
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.
