Geranium Himalayense Plenum, commonly known as the ‘Double-flowered Himalayan Cranesbill’, is a captivating perennial plant celebrated for its exquisite double blooms and attractive foliage. This cultivar is a delightful variation of the species Geranium Himalayense, originating from the mountainous regions of the Himalayas.
The plant forms a compact mound of deeply lobed, palmate leaves with a lush green colour and a slightly hairy texture. These leaves provide an appealing backdrop for the profusion of charming flowers that emerge during the Summer.
What sets this Geranium apart is its unique double flowers, which resemble miniature rosettes or pompons. Each flower features multiple layers of petals, creating a dense and intricate appearance and are blue-purple in colour, adding a delightful splash of colour to garden borders, rockeries, or cottage-style plantings.
This is a versatile and low-maintenance plant that thrives in a variety of growing conditions. It prefers well-draining soil enriched with organic matter and performs best in a location with partial to full sunlight. However, it can tolerate some shade, especially in regions with hot Summers.
This cultivar requires regular watering to keep the soil consistently moist but not waterlogged. Mulching around the base of the plant can help retain soil moisture and suppress weed growth. Deadheading spent flowers can encourage continuous blooming and maintain the plant’s tidy appearance throughout the growing season.
With its charming double blooms, vibrant foliage, and easy-to-grow nature, Geranium Himalayense Plenum is a delightful addition to any garden or landscape, bringing beauty and charm. Whether planted as a focal point or massed in drifts, this cultivar is sure to enchant and delight garden enthusiasts with its timeless appeal.
How to care for your Geranium Himalayense Plenum
- Sunlight: Plant in a location with partial to full sunlight. While it can tolerate some shade, it tends to bloom more profusely in sunnier spots.
- Soil: Ensure the soil is well-draining and fertile. Amend heavy soils with organic matter such as compost to improve drainage and provide nutrients. A slightly acidic to neutral pH is ideal for optimal growth.
- Watering: Water the plant regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases.
- Mulching: Apply a layer of organic mulch, such as shredded bark or compost, around the base of the plant to help retain soil moisture, suppress weeds, and regulate soil temperature. Maintain a mulch layer about 2-3 inches thick, but keep it a few inches away from the stem to prevent rotting.
- Fertilisation: Apply a balanced, slow-release fertiliser in early Spring, just as new growth begins. Follow the manufacturer’s instructions for application rates. Avoid over-fertilising, as excessive nutrients can lead to lush foliage at the expense of flowers.
- Deadheading: Remove spent flowers regularly to encourage continuous blooming throughout the growing season. This practice also helps maintain the plant’s tidy appearance and prevents self-seeding, which can lead to overcrowding.
- Pruning: Trim back any leggy or unruly growth as needed to promote a compact, bushy habit. Pruning can also rejuvenate the plant and stimulate new growth. Cut back the entire plant by one-third after the main flush of blooms to encourage a second round of flowering.
By following these care guidelines, you can enjoy the beauty of Geranium Himalayense Plenum’s double blooms and vibrant foliage in your garden for years to come.
