To help you get going, here are a few pointers. Remember to look at our main article on growing geraniums as well.
Where does Big Root Geranium Grow best?
The greatest places for this geranium to flourish outside are as ground cover, along walkways, and as garden edges. It may also be cultivated in a pot. Make sure it receives enough water if it is grown in a container because plants put there have a tendency to dry up more quickly.
It may make a stunning focal point in the landscape if used as a mass planting. Its abundance of foliage and blossoms will draw interest.
Plant Size
The height of this geranium, which ranges from.75 to 1 foot, makes it an excellent ground cover. It has a spreading habit of growth and can grow to a width of one to two feet. This geranium spreads via rhizomes, forming an underground network of entwined roots.
It develops at a typical rate and matures after three years of growth. Once planted, it can withstand drought. It can be divided easily and has a shallow, dense root system, allowing you to plant more of it and spread its development out across a larger area of your garden.
Growing Zones and Weather Conditions
The USDA plant hardiness zones 3–8 are the ideal ones for growing Big Root Geranium. This variation in hardiness demonstrates that this specific plant is tolerant to a variety of temperatures and environments.
This cultivar is ideal for southern gardeners since it can withstand heat and humidity. However, it also thrives in colder environments, providing the plant a wide range of conditions that it can withstand. It can grow to be almost as tall as an evergreen, depending on the growing environment.
Type of Soil
The optimum performance from the geranium requires wet, well-draining soil. It may grow in sand or dirt but loves rich soil. The several types of soil this plant can grow in really demonstrate how hardy it is.
Light, Water, and Fertilization
It needs full sun to some shade to function at its optimum. Although this geranium can tolerate the sun, it’s preferable to place it where the light isn’t too strong.
The amount of water this geranium requires is average. Don’t let it absorb too much water; just enough to keep the soil moist. Once planted, it can withstand drought.
Early spring fertilization with a 10-10-10 fertilizer will improve the health of this geranium and lengthen its blooming season.

Which geraniums reach the highest heights?
Plants like geraniums or Pelagonium require little care and reward gardeners with a long blooming season from early spring to summer. Depending on the cultivar, vivid flower colors and foliage are available. Geranium plants come in a range of sizes. Let’s examine some of the most popular geranium kinds in more detail.
Ivy-Leaved Geraniums (Pelargonium peltatum)
Because of their trailing habit, ivy-leaved geraniums make a beautiful choice for ground covers, window boxes, or hanging pots. Clusters of delicate blooms in mauve, purple, white, scarlet, or pink are encircled by lobed leaves that have a star form. Geraniums with ivy leaves can spread up to 48 inches and reach heights of 12 to 30 inches.
Zonal Geraniums (Pelargonium x hortum)
The most typical geranium in gardens and residences is the zonal variety. Either planted in outdoor garden beds or in pots indoors or outdoors, this species flourishes. The term “zonal” refers to the zone—a darker band of color—on variegated leaves, which are best recognized for their lush foliage. Single, semi-double, and double flower clusters with vibrant flowers, including red, pink, purple, white, orange, and bicolor variations, are produced by zoning geranium types. Zonal variants can get as tall as wide as 24 inches. The height and width of dwarf zonal geraniums range from 5 to 8 inches.
Regal or Martha Washington Geraniums (Pelargonium x domesticum)
A larger hybrid variety known as “regal geraniums” has erect, bushy growth. Round, somewhat serrated leaves make up the foliage. Regal geranium plants can reach heights of 12 to 48 inches and have clusters of solitary flowers. Purple, red, pink, white, and orange types of flowers have colorful blossoms. Angel geranium (P. crispum), a dwarf cultivar, grows to a height of 9 to 36 inches.
Is Big Root Geranium a perennial plant?
Some of the plants in this area will die after I go; any picky or timid ones will be trampled underfoot by their more ambitious neighbors. However, they do not include the best groundcovers, Geranium macrorrhizum (above), the hardiest epimediums, and other plants that are willing to flourish whether or not I pay them any attention, even in the most difficult environments like the dry shade of trees. I’ve learned to rely on plants like these to put things together quickly and easily:
Big-root geranium, Geranium macrorrhizum: I wonder how much of this plant I have cultivated across how many square miles. The bigroot geranium gets its name from the fact that it doesn’t form clumps and instead spreads out from a rhizome that hardly touches the ground at all. Even in my Zone 5B garden, its gorgeous foliage is virtually evergreen and has a fragrant, spicy perfume.
I don’t believe it will survive in the rain; sun, shade, or even dry shade. All I do is give it a yearly trim, which I perform as summer approaches, the flowers have faded, and the leaves are starting to climb higher. Deadheading is an alternative, although shearing the entire plant at once is quicker in large quantities and also maintains the plant tighter and denser.
If Pepto Bismol isn’t going to work for you, there is the more prim “Ingwersen’s Variety,” with practically white blossoms. The straight species is pink (but not pastel) (and a less rampant overall demeanor, too, I think).
Barrenworts, also known as epimediums, are now widely available in the market thanks in great part to the enthusiasm of Darrell Probst, a renowned epimedium collector and the owner of the Massachusetts nursery Garden Vision Epimediums. I have various excellent ones, but two of the less expensive (and consequently less rare) kinds, E. versicolor ‘Sulphureum’ and E. x rubrum (above, slower but steady and highly floriferous), have worked particularly well for me as groundcover (more ambitious from the start, with early yellow blooms, a real do-er, as they say).
Epimediums thrive in shady areas, and once established, they can withstand extreme aridity. Their woody rhizomes will actually rebel against a moist area and decay. Like many woodlanders with these woody underground components, I’ve discovered that they occasionally benefit from my intervention. When a cluster becomes excessively full, I go in and divide it and then repeat my success elsewhere with the divisions.
As we have previously indicated, prepare to trim back their virtually evergreen leaves in late winter.
I strongly advise contacting or writing Garden Vision, which is now owned by Karen Perkins, who has collaborated with Darrell from the company’s foundation in 1997. There will soon be a website, but in the meanwhile, contact epimediums at earthlink dot net by phone at (978) 249-3863.
Hybrid Hellborus orientalis: At the risk of stating the obvious, the hybrid hellebores (seen in mass above) are highly resilient, spreading widely as their evergreen clumps enlarge. The primer on these tough guys (and a slideshow of some beauties).
Do you have any spots where one of these would be helpful in preventing weeds, shading the soil, and simply aesthetically connecting things? Or do you have any other trustworthy, excellent groundcovers to suggest?
Big Root Geranium: Is it harmful?
The species’ petals are pink in hue. Flowers come in a variety of colors, from white to magenta. Soft pink describes “Ingwerson’s Variety.” This was the conventional source for the harmful to dogs and cats oil of geranium.
Are geraniums rooted deeply?
Garden geraniums make excellent bedding plants as long as you give them enough room to breathe and prevent moisture buildup that could result in fungus.
When looking for a summer bloomer for border edging, they also work well.
They thrive in pots and are a go-to for window boxes and hanging baskets thanks to their short roots and compact form.
For striking mixed groupings, try mixing them with lobelia, fuchsia, trees from the conifer family, and other geraniums.
Pelargonium x hortorum can be grown indoors in addition to outdoors, which is especially helpful in cold climates as plants can overwinter there.
Long regarded as a gardener’s friend, the leaves’ strong aroma deters nuisance herbivores like rabbits, especially when crushed or rubbed. Even Japanese beetles might be repelled by them.
It appears that when the bugs eat the leaves, they become inebriated and become easy prey for birds and other animals that consume beetles.
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.

Are geraniums a suitable choice for landscaping?
Hardy geraniums are the ideal choice if you’re searching for a gorgeous groundcover to hide garden blights or fill up beds. In case there’s any confusion, they are not annual geraniums, which are found in the genus Pelargonium. Common names (which can be perplexing!)
Instead, perennial geraniums are wonderful as a groundcover in gardens. With their “spilling propensity,” they look stunning in hanging baskets and containers as well. They make a good, useful addition to landscapes since pollinators adore them and deer don’t like them.
Meet Geranium “Rozanne” if you want to add a celebrity with awards to your landscape or garden. She is renowned for her incredible performances in gardens, as you may already be aware. From late April until the first frost, this hardy geranium’s magnificent 2-1/2-inch violet-blue flowers with white centers bloom. While the abundance of blooms gives gardens beautiful color, the foliage adds year-round interest by changing from a deep green to a reddish-brown hue in the fall. “Rozanne” spreads out between 24 and 28 inches, covering the garden in a carpet of vivid blue.
You’ll spend less time weeding and watering and more time resting and enjoying your garden if low-maintenance groundcovers are used to address your gardening concerns.
Do tough geraniums thrive in the 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 geranium has the longest flowering period?
For your Garden: Long-Blooming Hardy Geraniums
- Plant named “Ann Folkard” (Cranesbill)
- Plant named “Elke” (Cranesbill)
- Plant named “Mavis Simpson” (Cranesbill)
- “Orion” geranium (Cranesbill)
- Gardenia patricia (Cranesbill)
- Rosane geranium (Cranesbill)
- Pink “Sweet Heidy” geranium (Cranesbill)
Prune Heavy Once per Year
Hardy geraniums enter a dormant state over the winter every year. Most people can endure colder temperatures. Most of them won’t die, but they don’t grow.
That depends on the local climate. Cut back the geraniums to three to four inches in the fall if the weather is consistently below zero, and then overwinter the plant indoors.
Geraniums may often survive the winter outdoors in mild winters with just a nice, thick covering of mulch.
Spring Prune to Prepare for Blooms
The spring cutback is the first reduction of the year. Check the plant at this point for brown or fading leaves. Since they offer no benefit to the plant, they are the first to perish.
Examine the stems for rigidity. Cut off any stems that feel spongy. When gently squeezed, healthy stems should feel solid.
Summer Prune for More Vibrant Blooms
Deadheading season is during the summer. removing the stems that the flower buds were attached to in order to remove spent and fading flowers.
Geraniums should ideally be clipped three times a year, not including routine deadheading of the season’s wasted flowers. The best seasons to prune geraniums for shape and to promote bushy growth are spring or fall.
Because they are promoted as being simple to grow, geraniums are quite popular. They are that. They are not shrubs, though. They are shrubs that develop tall, slender stems on their own.
Geraniums must be regularly pruned to maintain their shape; otherwise, they will continue to grow straight up.
