grey cranesbill 'Splendens'


The Geranium 'Splendens' is characterized by its strikingly vibrant magenta-pink flowers, which make a bold statement in any garden setting. Each petal is distinctively veined and may feature a slight gradient of color, giving depth and intricacy to the overall floral display. The center of the flowers is marked by a darker magenta hue, sometimes appearing almost black, which highlights a striking contrast against the lighter tones of the petals. Foliage on the Geranium 'Splendens' is equally notable with its impressive, dense clusters of leaves that are as attractive as the blooms themselves. The leaves are broadly circular in shape, with a rich green color and a lush appearance that provides a perfect backdrop to highlight the bright flowers. These leaves often have a slightly ruffled or lobed edge, which adds texture and visual interest to the plant. Seasonally, this Geranium variety comes to life with its blooms, typically drawing attention from late spring to early summer. The plant continues to provide visual interest throughout the growing season with its enduring foliage, which can turn to attractive shades as the days grow shorter, depending on the surrounding climate conditions. The Geranium 'Splendens' is a low-maintenance addition that ultimately brings splashes of vibrant color and a touch of natural beauty to rock gardens, borders, or containers where its ornamental qualities can be fully appreciated even without taking its size into consideration.

  • water dropWater

    Grey-leaf geranium prefers soil that is kept evenly moist but not soggy. You should water the plant when the top inch of soil feels dry to the touch, which typically means watering once a week. Depending on the environmental conditions, such as temperature and humidity, the frequency may vary. When watering, provide enough water to saturate the soil without leaving standing water, which can be about 1-2 gallons for an average-sized plant in a pot. During the winter months, reduce watering frequency as the plant enters a dormant period and requires less moisture.

  • sunLight

    Grey-leaf geranium thrives best in full sun to partial shade conditions. An ideal spot would be one where the plant receives at least six hours of sunlight daily. If grown indoors, a south or west-facing window can be a good location, ensuring the plant gets enough light without exposing it to the scorching midday sun, which could cause leaf burn.

  • thermometerTemperature

    Grey-leaf geranium favors temperate climates and performs well in temperature ranges of 55 to 75 degrees Fahrenheit. It can tolerate minimum temperatures down to 30 degrees Fahrenheit but should be protected from frost. Ideal conditions include daytime temperatures around 70 degrees Fahrenheit and slightly cooler temperatures at night, but not below 55 degrees Fahrenheit.

  • scissorsPruning

    Pruning grey-leaf geranium helps maintain its shape, encourage bushier growth, and remove spent flowers and damaged leaves. Prune lightly throughout the growing season as needed to remove dead flower heads and encourage a second bloom. The best time for a more thorough pruning is in early spring or after the last frost date in your area, when you can cut back leggy stems to promote new growth.

Regular organic matter amendments will help maintain soil fertility.

  • circleLife cycle

    Geranium subcaulescens 'Splendens', commonly known as Geranium or Cranesbill, begins its life cycle when the seeds germinate, ideally in spring or early summer, after experiencing moist, cool conditions. The seedlings develop into rosettes of leaves close to the ground and, given adequate light and water, will grow and establish a root system. Over time, the plant matures and produces distinctive lobed leaves and erect flowering stems, generally during late spring or early summer. The flowers are hermaphroditic, featuring five vividly colored petals, and are pollinated by insects, after which they produce the characteristic beak-like fruit that gives the Cranesbill its common name. Once mature, the plant experiences a period of dormancy, usually during colder months when growth ceases temporarily. Every year, the plant can reemerge from dormancy to start a new growth cycle, continuing this process for several years as a perennial.

      Spring to Summer

    • The most popular method of propagating Geranium subcaulescens 'Splendens', commonly known as Hardy Geranium or Cranesbill, is through division. This should ideally be done in the early spring or autumn. To propagate by division, carefully dig up the whole plant, ensuring to keep as much of the root system intact as possible. Use a sharp, clean knife or spade to gently split the plant into smaller sections, each with a portion of root and several shoots. These sections can be immediately replanted in well-draining soil, watering them well after planting to help establish the root system. Within a few weeks, these divisions should begin to grow and flourish, replicating the parent plant's characteristics.
