“The phrase “scented geranium” is a general name for Pelargonium species with fragrant leaves and/or flowers.
Compared to garden geraniums, these species and cultivars often have smaller leaves and blooms (P. x hortorum).
For example, in the image below, the plant on the right is a zonal geranium, whereas the plant on the left is a “geranium with a lemon scent.
These plants have glands that produce the fragrant oil. The oils are produced when the leaves are crushed or otherwise disturbed, giving off a sweet perfume.
Although perennial in USDA Hardiness Zones 10 and 11, scented geraniums are typically planted as annuals.
You can bring your magnificent plants indoors for the winter if you don’t live in one of these places and don’t want to toss them on the compost pile every year.
Naturally, scented geraniums can’t tolerate much cold, but some plants, especially the smaller-leaved variety, can tolerate temperatures as low as Zone 8.
Some can flourish in Zone 12. In Zone 8, plants often die back to the ground in the winter and emerge again in the spring.
A Note of Caution:
Dogs and cats are poisoned by all Pelargonium species. Any portion can cause ataxia, depression, and hypothermia in big dosages and vomiting, nausea, and diarrhea in pets when consumed in modest levels.
Can fragrant geraniums endure winter?
Scented geraniums’ lovely scent should be all around you. These fragrant plants, which belong to the genus Pelargonium, are relatives of the common garden geranium. Numerous fragrant geraniums are heirloom plants that have endured over time because of gardeners who took cuttings and shared the fragrant offspring. Like other fragrant geraniums, rose geranium produces fragrant oils in its leaves. Scented geraniums are attractive flowers that are simple to grow. Green, blue-green, and variegated tones can all be seen in the leaves as they unfold. Give plants a position in full sun, fertile soil, and well-drained soil. Provide protection from the harsh afternoon sun in southern locations.
Temperatures between 55 and 70 degrees Fahrenheit are ideal for scented geranium growth. Plants are stressed by higher temperatures, so when the summer heat comes, be sure to give them enough moisture.
Grow aromatic geraniums in pots or garden beds, such as rose geranium. Due to their lack of winter hardiness, most gardeners plant these aromatic beauties as annuals. Use a commercial soil-free planting mix designed for use in pots if you’re growing fragrant geraniums in them. These mixtures offer the superior drainage that fragrant geraniums require.
It is simple to overwinter these fragrant plants, either in containers or by using cuttings. Give potted scented geraniums a place next to a light east or south window for the optimum growth if you move them indoors for the winter. Inside, plants will slenderize. Trim them as necessary to control growth.
Another method for preserving scented geraniums through the winter is to take cuttings. Cuttings of scented geraniums are more prone to decay than other geraniums from the Pelargonium genus. Cuttings should be dipped in a mixture of 2 tablespoons of home bleach and 4 drops of liquid dish soap in 2 quarts of water to avoid this. Cuttings should be let to dry overnight before planting the following day.
Scented geraniums are adaptable indoor plants. You can use fresh leaves in the kitchen or dry them out to make potpourri. Chopping fragrant geranium leaves fresh to add to cookie or cake mixes is a typical kitchen usage. Or use full leaves to line a cake pan before adding batter and baking. Slice the leaves off the bottom of the cake after baking, or leave them on and enjoy the crunchy bite. A tasty sweetener is made by layering whole perfumed geranium leaves with sugar.
Native to South Africa, scented geraniums are from the Cape of Good Hope. Scented geraniums, such as rose geranium, gained to popularity as perfume ingredients in the 1700s. In place of pricey rose attar in perfume, the rose geranium Pelargonium capitatum, sometimes known as Attar of Roses, was utilized.
In Kenya, which was then owned by the British, rose geranium farms started to appear. Although the geraniums are grown in Egypt, China, and India, rose geranium oil is still used today to substitute expensive rose attar in perfumes. 2.5 pounds of rose essence are produced from one ton of rose geranium leaves.
How can I tell if my geranium is a perennial or annual plant?
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.
How old are fragrant geraniums?
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.
How are scented geraniums overwintered?
Given that pelargoniums are indigenous to South Africa, it is not unexpected that they cannot withstand extremely cold temperatures, let alone icy winters.
Only the U.S. Department of Agriculture plant hardiness zones 10 and 11 are suitable for growing scented geraniums in the winter.
In other zones, their main protection from frost damage is overwintering techniques.
Having said that, geraniums like a minimum temperature of about 19 degrees Fahrenheit. This does not imply that the plant won’t suffer harm at this temperature, but rather that the harm from the cold might only be slight.
Your pelargoniums should typically be prepared for overwintering when the fall evening lows begin to fall below 55 degrees Fahrenheit.
Placing potted geranium in cool storage
What you must do if you have decided to use the cool storage overwintering approach is as follows:
- Find an area where the temperature doesn’t drop below freezing for your geraniums (garage, basement, shed, cellar, etc.). It ought to be a cool location.
- Trim the plant back by a third to a half, and take out any sick or damaged areas.
- deeply wet, then put in storage
- During the winter, water sparingly and inspect the plant for illness symptoms.
Placing bare root geranium in cool storage
Similar to the last example, you can also overwinter scented geraniums in cool storage by placing them in an unheated area where the temperature doesn’t drop below freezing, but this time you won’t be using pots or soil.
What you must do is as follows:
- Remove the plant from its container and clean the roots’ dirt.
- After letting the plant dry naturally for a few days, wrap it in paper, newspaper, or cardboard and set it on a shelf.
- Every month, bathe the plants for one to two hours in warm water.
- Let dry a little before putting back in storage.
The geranium should be kept dry and away from moisture, which would encourage mold. Never let it dry up entirely though. The plant can be kept alive by giving it a monthly watering.
Do geraniums survive the cold outside?
- Make sure you thoroughly inspect your geranium plants before bringing them inside for the winter. Look for symptoms of pests and illnesses like rust and remove any dead leaves or wilting blossoms. Only zonal pelargoniums are impacted by this, but it is becoming more widespread. It arrived in the nation for the first time in 1968, and it does best in the moist summer or fall months. Fortunately, it doesn’t seem to spread to the plants quickly and is simple to treat, so merely plucking the afflicted leaves is an effective management. You might also consider using the fungicide Dithane 945 as a spray.
- Placing your overwintering plants somewhere bright and sunny will help them retain their need for light throughout the winter. Your plants will receive 50% less light if they are placed more than three feet from a window!
- Because your plants continue to thrive throughout the winter, keep the roots moist. While geraniums frequently survive droughts, they rarely flourish. Show plant growers take special care to keep the roots of their plants damp but never soggy during the winter.
- Ventilate as frequently as you can to maintain a dry environment surrounding your plants. Your plants will turn into a moldy, rotting heap if you don’t allow the air to circulate. The greatest electric fan heaters are those that operate automatically since they circulate air while simultaneously raising air temperature.
- Geraniums are fairly inexpensive to overwinter in the greenhouse because they only need to be kept frost-free. To keep temperatures above freezing, however, we do advise utilizing a heater. Set the thermostat on your heater to 5C, which is 41F. The plant will not survive if the stems become frosty! The winter months are a great time to store your delicate pelargoniums in porches, sunrooms, or conservatories.

Can I store my geraniums for the following season?
Amazingly, annual geraniums (Pelargonium hybrids) thrive and flower wonderfully from spring till frost with little effort. The next spring, these resilient tiny plants will take off and grow once more if you dig them out in the fall and store them in a cardboard box or paper bag for the winter. Learn how to preserve your geraniums over the winter so you can enjoy them year after year by watching our video and reading the article below.
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.
