This attractive plant grows carefree and can tolerate practically any soil. It prefers soil that is humus-rich, loamy, a bit damp, and well-drained—not waterlogged or too saturated.
Cranesbills flourish in the soft shadow provided by high treetops, and they will grow best in areas with morning sun or partial shade.
A perennial with a long lifespan, its growth is modest in the first few years. The spectacle these plants put on, however, lasts from late spring through October after a mound has formed.
Furthermore, they gain from routine deadheading. By mid-summer, growth may be sluggish in some cultivars, and your chubby, attractive mound may appear somewhat worn out and lanky.
To renew, reduce the mound by half to promote fresh blooms and extend the growing season. To keep some blossoms while new growth develops, shear the plant in two, about two weeks apart, or do it all at once.
Seed collection, stem re-rooting in water, semi-ripe wood cuts in the summer, or root division in the fall or spring are all methods of propagation.
For blooms the next season, collect seeds all through the summer and then sow them in the spring or early summer.
Although deadheading keeps the plant compact, it also results in the loss of seedheads. Allow some pods to stay on the plant to mature in place if you want to start plants from seeds.
Cranesbill is one of the plants that may form roots in water due to stem rooting.
Recall all the teacups your grandmother had on her windowsill filled with plant cuttings? They might have been geraniums, for sure!
Cut the stem right below the node where the leaves join the stem with a sharp knife to ensure strong, healthy roots. Leave the top two or three leaves in place and remove the lower leaves. Remove all blooms as well; energy should be used to produce roots rather than seeds.
Put a number of cuttings in a clear container of water, and change the water as needed or every few days. In order to protect and shade the tender new roots, which typically emerge in 3–4 weeks, use an opaque container.
Place the container containing the cuttings on a bright windowsill or in a protected area of the garden that receives 2 to 6 hours of soft sunlight each day. The finest lighting is early morning or dappled shade.
Plant as for stem cuttings below once healthy roots reach a length of about 1-2 inches.
This year’s growth is chosen for the semi-ripe wood. The cuttings’ tips are still sensitive and green, but their bases will be older and harder. From mid-summer until mid-autumn, semi-ripe wood can be harvested whenever it is available.
Put root divisions and stem cuttings in little pots with a light, sandy potting soil. For a period of one to two years, or until they are old enough to be buried, you can also place them in a nursery bed.
Are cranesbill geraniums shade-tolerant?
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.
Are cranesbill geraniums sun-sensitive?
Geraniums are a diverse species of hardy perennials that provide abundantly blooming plants for a variety of settings. The blooms, which come in vivid as well as more muted tones of genuine blue, lavender, pinks, and white, can be just as intriguing as the lobed foliage. The delicate container plants known as Scented Geraniums, Zonal Geraniums, and Martha Washington Geraniums have little in common with these plants (these belong to the same family, but a different genus, Pelargonium).
Light/Watering: These plants will perform at their best in light shade to full sun in the North and part shade in the South. Most are able to adapt to brief dry spells well, and all benefit from routine watering. In milder areas, Geranium sanguineum and its variants can withstand drought.
Geraniums do best on average, well-drained soils that range from slightly acidic to neutral, and they will benefit from a little springtime application of balanced, granular fertilizer. Most people can handle brief, dry periods.
Size & Growth
Although the height of cranesbills varies depending on the species, they often fall under the category of higher shrubs and can grow anywhere between 12 and 20 inches in a year.
However, they have a spread of typically between 18 and 24 inches and are mounding plants.
Although the plants are native to temperate regions, they are extensively grown under similar circumstances all over the world.
Hardy geraniums can be identified by their dark green, citrus-flavored leaves, which is why they are sometimes called scented geraniums.
These plants’ autumnal foliage, which consists of a mixture of brown, golden, burnished bronze, and red hues, produces a stunning display.
Flowering and Fragrance
Beautiful flowers in white, purple, magenta, lilac, blue, violet-blue, and pink hues are produced by the plants in the summer.
The blooming season for many cranesbill species begins in late spring and lasts into late October.
These geranium types are a popular choice for gardens because of their lovely bloom hues.
Light & Temperature
True geraniums thrive in full sun, but they also like midday part shade.
The best locations for these plants are those that provide them with morning sunlight and afternoon light shade.
Watering Requirements and Feeding
However, be careful not to overwater as they cannot thrive in soil that is saturated with water or has standing water.
When the new foliage is just beginning to emerge in the early spring, the flowering perennial plant species benefit from a yearly feeding with a balanced 10-20-10 fertilizer.
After mid-summer deadheading, the fertilizer should be administered again as soon as the plants begin to produce new growth.
These geranium species shouldn’t receive any more fertilizer than this because excessive fertilization frequently results in sprawling and lanky growth.
