Take advantage of Geranium Rozanne, which marketers have dubbed the geranium of the new century. This variety of cranesbill geranium blooms on a perennial basis. The name is derived from the Greek word geranium, which means crane. The geranium seed capsule, which has a long, column-like beak, is referred to as a cranesbill in this phrase. Although the Rozanne geranium is sterile and does not set seed, it has ancestors that are other cranesbill geraniums.
A Somerset, England, home garden is where the Rozanne geranium was first found. The two blue-flowered cranesbill geraniums, Geranium himalayense and Geranium wallichianum ‘Buxton’s Variety, naturally crossed to produce it. In comparison to its parents or other cranesbill geraniums, the offspring has larger blooms, stronger heat tolerance, and a longer flowering window.
When the flowers of the Rozanne geranium open, they appear to nearly shine in the garden. Each flower has a white eye in the middle. Petals have darker violet-blue streaks that act as a nectar-guide for pollination insects. From late spring through early October, the Rozanne geranium continuously releases its 2.5-inch-wide flowers. Gardeners describe spots of flowers as late as December in areas with mild winters.
This geranium also has some shimmering leaves. These leaves have the deep lobes typical of cranesbill geraniums, but they also contain chartreuse-colored marbling. The leaves changes to crimson and copper colors in the fall, enhancing the color of the garden.
The rozanne geranium spreads 24 to 28 inches wide and develops to a height of around 20 inches. Rozanne doesn’t always grow into a tidy mound like other cranesbill geraniums. Instead, it meanders aimlessly about the garden, climbing other trees and shrubs. Simply trim rambling stems to the desired length whenever you feel they are becoming too much during the growth season. In response, the plant will branch out and maybe flower.
Despite being hardy in Zones 5 to 8, gardeners in Zone 4 report years of good overwintering with this cranesbill geranium. If there is no snow cover in your Zone 4 garden, add a winter mulch. This geranium should be planted in an area with organically rich soil. The soil has to be damp but well-drained. Rozanne geraniums can grow in full sun or light shade, but full sun promotes the finest flowering. In hotter areas, definitely provide shade in the afternoon. Deer and bunnies typically avoid this flower, according to gardeners.
Rozanne geranium plants don’t require deadheading because they are sterile. After the first flush of flowers, shear plants back to reduce their size somewhat. To promote branching development and subsequently shorter stems, trim stems as short as three inches. Cut stems in the late fall after the first frost or in the early spring before new growth appears to clean up the garden.
Rozanne geranium complements roses effectively because of the way it wanders, which helps conceal canes with knobby knees. It fits perfectly in with a rock garden and gets along well with daffodils. Rozanne geranium leaves can be relied upon to cover up withering daffodil stems. Use Rozanne geranium near the front of a border to create a riot of color.
Do I need to deadhead the geranium Rozanne?
Hardy geraniums, also known as cranesbill, are perennial border plants with saucer-shaped flowers in pink, purple, and blue hues. They are simple to grow, do well in the shade, and bloom for months. Geraniums are well-liked in cottage garden plans and provide a lengthy season of pollen and nectar for many pollinators, especially bees.

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.

Pruning Geraniums After Winter Dormancy
The optimum time to prune geraniums is in the early spring if you put them into dormancy for the winter or if you live in a region where they lose some of their leaves over the winter.
Take off all of the geranium’s brown and dead leaves. After that, remove any diseased stems. Squeezing a healthy geranium stem will feel firm. Cut down the geranium plant by one-third, paying particular attention to stems that have begun to turn woody if you want a less woody and lanky plant.
Cutting Back Geraniums That are Wintered Alive
The best time to prune geraniums is in late fall or right before you bring them inside, if you intend to bring them indoors. If you do not put your geraniums into dormancy for the winter and they remain green in the ground or in containers year round.
Trim the geranium plant back by one-third to one-half, paying special attention to lanky or woody stems.
How to Pinch Geraniums
In order to make the plant grow more bushy and compact, geraniums are sometimes pruned. You can pinch either newly purchased bedding geranium plants or geraniums that have been overwintered. Pinching of geraniums begins in the spring.
When a stem on a geranium plant reaches a few inches (7.5–10 cm), cut off 1/4–1/2 inch (0.5–1.5 cm) of the stem with a sharp pair of scissors, or even with your fingers. Repeat over all stems. The geranium will be forced to produce two new stems off of the original stem as a result, which will result in a bushier, fuller plant. If you prefer, you can keep pinching geraniums all throughout spring.
Geranium pruning is simple and improves the appearance of your plant. You may enjoy your geraniums more now that you know how to prune geranium plants.

After flowering, should you prune 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.
Spring Perennial Pruning
Geranium as In order to gently trim around the young green shoots that are starting to force their way upward through the earth, Rozanne carefully prunes back dead foliage to a height of around 7 cm (3 inches) as she awakens from her winter rest.

When should hardy geraniums be pruned?
Hardy geraniums require hardly any maintenance. Rabbits don’t seek them, while slugs and snails prefer to consume other plants. After their initial flowering, they can be trimmed right back to the ground, and the next summer, they will produce new foliage and additional blooms. Avoid cutting back too soon after flowering because some hardy geraniums have lovely autumn leaves.
Propagating hardy geraniums
Hardy geraniums don’t typically need to be propagated because seedlings may be easily removed from the garden and potted up. In the spring, plants can be lifted and divided. Hardy geraniums can be challenging and time-consuming to grow from seed.
Growing hardy geraniums: problem solving
Geraniums that are hardy are generally trouble-free. However, the geranium sawfly larvae have been known to attack them (Ametastegia carpini). These appear to be 12mm long, small grey caterpillars. They leave unattractive lace-like holes in the leaves after they eat them. In your garden, the more resilient geraniums you have, the more probable it is that they will reproduce.
Since they fall off the leaves when the plant is disturbed, the larvae might be challenging to see. The months of May and September see the most activity; the September generation pupates in the soil and spends the winter there before emerging in the spring to deposit eggs on the foliage. Even though the damage can be extremely unattractive, the plant rarely becomes less vigorous as a result. The following steps could assist in keeping them in check:
- Many geranium sawfly larvae overwinter in the soil, therefore clearing away debris and lightly raking the soil beneath vulnerable plants will expose the larvae to the elements, where they will be killed by frost and devoured by birds and other predators.
- From May on, carefully inspect the undersides of leaves for signs of the eggs and larvae and remove them by hand if possible to prevent numbers from growing.
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.
What is causing my geraniums to get leggy?
If hardy geraniums are planted in their growing zone, they will return year after year. These plants, which add color and cheer, are typical of cottage gardens. Depending on the cultivar, its blossom color ranges from a delicate blue to a deeper purple, occasionally with pinkish undertones.
They often spread throughout a garden bed as they mature, reaching heights of 1 to 1 1/2 feet. The Missouri Botanical Garden notes that certain dwarf types, such Geranium ‘Bertie Crg,’ may only grow to be 4 inches tall.
Full sun is ideal for geraniums. Make sure to place them where they can soak up the light because one reason they could get leggy is if they are growing in too much shadow. Additionally, they need soil that drains well, as waterlogged soil can also cause lanky geraniums.
