Pelargonium peltatum (Ivy Geranium), a native of South Africa, is a trailing, evergreen perennial with meaty, glossy, brilliant green leaves that are 2-3 inches across (5-7 cm). The common name comes from their pointy lobes, which resemble those of ivy (Hedera), thus the name. From spring to fall, rounded clusters of single or double flowers in hues of red, pink, lavender, or white can be seen. In climates with chilly evenings and sunny days, this plant thrives. Ivy Geranium is a lovely addition to hanging baskets, window boxes, and raised beds where it will cascade elegantly down and create a waterfall appearance. It offers a summer of luxuriant flowering.
- reaches heights of 1-2 feet (30-60 cm) and a width of 3-5 feet (90-150 cm).
- Performs best in full sun or light shade, medium moisture, well-drained soils with average to organically rich soils that are neutral to slightly alkaline. During the growing season, water often. Best in full sun, although in the hottest temperatures, appreciates some partial shade. Once established, it is tolerant of drought.
- Excellent option for Mediterranean gardens, containers, hanging baskets, and window boxes. also makes an excellent groundcover!
- In milder climates, the annual plant Pelargonium peltatum is grown in the ground and is hardy to USDA zones 10 to 11.
Ivy geraniums: Will they reappear?
To ensure a successful overwintering, take the following actions after removing the entire plant from the flowerbed or container:
- In a cold, well-ventilated space, such as a garage or basement, arrange the plants in a single layer on a wire rack or on sheets of newspaper.
- Give the plants three or four days to dry.
- You can get the plants ready for storage once they appear dry and the last of the soil has washed off the roots. Any of the following methods can be used to store ivy geraniums:
- In a calm, dark room, hang the entire plant from the rafters or a clothesline.
- Put each plant in its own paper bag. Fold the top of the bag over, hang them in a basement closet like bare plants, or attach pant hangers to the tops of the bags. The bags allow you to name each plant individually to organise them for planting in the spring and further shield the dormant plants from light.
- The dry plants are stacked in a cardboard box. If utilising this technique, make sure the box is in a location that is well-ventilated and dry.
Repot your ivy geraniums in the early spring, put them in a sunny spot, and start giving them regular waterings. They will soon send out new shoots, allowing you to enjoy your flowers for a second season.
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 centre 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 should ivy geraniums be stored during the winter?
Geraniums are incredibly simple to store for the winter—just place them in a cardboard box or a paper bag and secure the top. The following advice will help them survive:
- Maintain geraniums in a cool, dry area with a temperature of 50 to 60 degrees F.
- Once a month or so, remove dried leaves from the bag or box and check for mould.
- Check the stems quickly at the same time; they should be stiff. Throw away any dried-out, shrivelled stems you uncover.
- If you see that the plants are becoming really dry and crispy, give them a brief soak in water.
- Plants with stems that appear to be blackened or mildewed should be disposed away.
Geraniums are typically kept in a sack upside down. Although the exact cause is unknown, one idea holds that it does so by pushing moisture into the stems. Whatever the cause, storing them in this manner is neither harmful nor necessarily harmful.
Are annuals trailing geraniums?
Numerous cultivars and hybrids produced from Pelargonium peltatum, one of several species that are frequently referred to as “annual” or “garden” geraniums, are given the common name ivy geranium (or ivy-leafed geranium). The trailing habit of the P. peltatum kinds makes them perfect for hanging baskets, window boxes, and other containers. Ivy geraniums, like perfumed or regal geraniums, are perennial evergreen plants that are indigenous to South Africa and do not belong to the geranium genus at all. Its broad, fleshy lobed leaves and flower umbrels that extend on stalks are similar to those of other Pelargonium species. Ivy geraniums, meanwhile, have stems that trail and cascade and can grow up to 5 feet long. Except in tropical climes, where they are typically grown as annuals, pelargoniums are delicate perennials (zones 10 to 12). Warm spring months encourage rapid plant growth, allowing you to fill large containers or baskets with more affordable, quicker-maturing smaller plants.
Ivy geraniums are often grown as container annuals that are planted in the spring and bloom up until the first frost. Ivy geraniums, like other Pelargonium species, contain mildly poisonous geraniol and linalool chemicals that can irritate the skin and gastrointestinal tract in both humans and animals. Cats are particularly prone.
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 mouldy, 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 utilising 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.

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 favourite mulch, and your favourite 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.

Which geraniums grow year round?
Geraniums actually belong to two different botanical subgroups. The perennial varieties are the real geraniums. The geraniums that most people envision when they go plant shopping are the annual bedding varieties with flowers that resemble lollipops and are mounted on stick stems. The plant genus Pelargonium includes several bedding plants. Ivy geraniums, aromatic geraniums, and Martha Washington geraniums are just a few of the numerous additional geraniums that belong in the Pelargonium genus.
What should you do with geraniums in pots throughout the winter?
Geraniums can be overwintered inside in three different ways: as a houseplant, as a dormant bare root, or as cuttings. Your decision will be influenced by the amount of room you have indoors and the range of temperatures you can tolerate. Here is a closer examination of each method.
Overwintering geraniums as houseplants
If you want to keep the entire potted plant and have lots of room close to a window that gets bright, direct light, go with this option. A draughty west-facing window would be the ideal place for your potted geranium to spend the winter because geraniums prefer it chilly (55 to 65 F is optimum).
Wash the foliage well with your hose and repot the plant in new potting soil to prevent bringing unwanted pests from outside. You might also use insecticidal soap, which is sold in most garden centres and hardware stores as well as online. Avoid taking the plant indoors if it shows any signs of pests or illness. Only strong plants have a chance of successfully overwintering indoors.
During the winter, keep the soil wet but not damp. No more humidity is required. If the stems begin to sag, pinch them back to keep the plant compact throughout the winter. When springtime comes around, you may start fertilising once more and transfer the plant back outside as soon as the temperature reliably rises above 50 F.
Overwintering geraniums as dormant bare root plants
This is the most typical way to overwinter geraniums, but it won’t work unless you have a dark, dry place that stays around 50 degrees throughout the winter.
First, dig up your geranium before it freezes and shake the dirt off the roots. To stop mould from forming, let the plant sit and dry for a few days before storage. Before moving onto the following phase, the roots must be completely dry.
The roots should be kept in a dark, dry place that doesn’t get colder than 45 degrees throughout the winter. Geranium roots should be kept at a temperature of 50 F. You can keep them by doing:
- It has been customary for generations to hang the plants upside-down from the rafters;
- placing them on a shelf after wrapping them in newspaper or a paper bag;
- they were put in a cardboard box.
Step 3: Every month or so, look for mould, black leaves, or limp stems at the roots. Remove any plant or root components that are harmful. Most of the stems should endure the winter in good shape. Before re-storing them if they become too wilted, give them a good bath in water and let them air dry.
Step 4: Reviving your geraniums involves cleaning them up, pruning the stems back to healthy green growth, and replanting them in new potting soil about six weeks before your final frost date. Where the new roots will grow, bury the stems two nodes deep. When you notice fresh growth in one to two weeks, keep the plants somewhat dry; after that, keep the soil moist until the plants are big enough to replant outside.
Overwintering geraniums as cuttings
If your light windowsill area is limited or you are concerned that bringing in your entire potted plant would also attract unwanted bugs, this is a nice technique to try. Additionally, it’s a fantastic way to multiply your existing geraniums.
To trim plants, you’ll need:
- a cutting edge.
- Most hardware stores and garden centres sell rooting hormone, which is sold online.
- Use little terracotta or plastic pots, or recycle a clear takeaway container for roasted chicken.
- If you don’t eat chicken, use clear plastic bags to cover the pans.
How hardy are ivy geraniums?
The plant can reach heights of 1’2 feet and a width of 3’5 feet under ideal conditions.
It can grow relatively quickly and produce flowers if watered often in the summer and protected from the elements in the winter.
Flowering and Fragrance
The characteristics of ivy geranium plants that are most liked are their compact growth and profusion of flowers.
The plant creates inflorescences that resemble umbels and are filled with 2 to 10 symmetrical, odourless flower buds.
The two upper petals curl back about 90 degrees and may feature dark patterns.
Throughout most places, the plant blooms in the summer, but all year in its country of origin.
Ivy geraniums open their blooms in semi-double flower clusters, although they have a looser shape than their zonal geranium relatives, who have ball-shaped blooms.
Light & Temperature
Although the Ivy Geranium plant is sturdy and thrives in full sun or light shade, prolonged exposure to high temperatures is not advised.
It may grow as an annual in milder climates and is hardy in USDA hardiness zones 10 to 11.
The plant does require some protection when the temperature lowers because it is dormant throughout the winter.
Watering and Feeding
Water the plants more regularly to maintain soil moisture when it gets too hot and dry outside.
Ivy Geranium needs to be fertilised frequently because it is a greedy plant.
Use organic fertiliser or a slow-release fertiliser if your Ivy Geranium is planted in a garden.
Maintain soil moisture, paying close attention to geraniums in hanging baskets so that air can flow freely throughout.
Soil & Transplanting
Ivy Geraniums dislike soggy soils because they are prone to root rot.
The ideal option is to stick with well-drained garden soil that has been treated with organic compost.
Grooming and Maintenance
You don’t need to spend a lot of effort pruning or shaping this plant.
Regular deadheading promotes a consistent supply of flower buds throughout the flowering season.
