Common Names:
The Reflexed Geranium is known by different common names depending on the region. In English, it is called Reflexed Geranium, whilst in German, it is known as the Nerve Geranium because of its distinctive veined leaves. Other common names for Geranium reflexum include Blue-slipper, Cranesbill, Plateau Geranium, and Spreading Geranium.
Uses:
The Geranium reflexum is commonly used as an ornamental plant for landscaping purposes. It is particularly popular because of its vibrant blue flowers that bloom from May to July, making it an excellent selection for gardens, parks, and border planting. It is also utilized in traditional medicine as an antiseptic against mild skin conditions and wounds.
General Appearance:
The Reflexed Geranium is a low-growing plant that often forms mats or spreads over the ground up to 50 cm wide. It has stems that are thin and fragile and usually covered with purple-red hair. The flowers are usually 15-20 mm in diameter and have five bright blue-violet petals. The leaves of Geranium reflexum are unique as they are divided into two parts, the upper part is kidney-shaped, and the lower part has three rounded lobes.
Light Requirements
Geranium reflexum Andrews is a sun-loving plant that requires full sunlight. It grows best in areas that receive at least six hours of direct sunlight every day. If grown indoors, it should be placed near a south-facing window that receives plenty of sunlight.
Temperature Requirements
Geranium reflexum Andrews is a hardy plant that can tolerate a wide range of temperatures. It grows well in most areas and can withstand temperatures as low as -20°C during winter and as high as 35°C during summer. However, it prefers moderate temperatures between 15°C and 24°C for optimal growth.
Soil Requirements
Geranium reflexum Andrews grows best in well-draining soil that is moderately fertile and slightly alkaline. It can tolerate a wide range of soil types, including loam, sand, and clay, but it prefers slightly dry soil. It does not grow well in waterlogged soil or areas with high humidity levels.
Cultivation Methods
The Geranium reflexum Andrews plant is a hardy, low-growing perennial that typically grows in rocky areas and dry, open woodlands. It requires well-draining soil that is slightly acidic and is tolerant of drought and low-nutrient soil. When planting, ensure that the roots are well-covered with soil and the planting hole is deep enough to accommodate the entire root system. Geranium reflexum Andrews requires direct sunlight for at least six hours a day to thrive.
Watering Needs
This plant requires moderate watering and is tolerant of drought. The water should reach the root system, which means that surface watering should be avoided. Overwatering can cause root rot, which could be fatal to the plant. Ensure the soil is dry before watering again. The best times to water are in the early morning or late evening to minimize evaporation and ensure that the roots absorb the moisture before the sun dries out the soil.
Fertilization
Geranium reflexum Andrews prefers low-nutrient soil and does not require frequent fertilization. Fertilizers should be applied sparingly, and it is recommended to use organic fertilizers. Fertilization should be done during the plant's active growing season, which is generally in the spring and summer. Excessive fertilizer application can increase the plant's susceptibility to diseases and pests.
Pruning
Pruning is necessary to keep Geranium reflexum Andrews looking its best. It should be done in the spring after the last frost. Pruning involves the removal of dead, damaged, or diseased parts of the plant. It also helps to keep the plant from becoming overly woody and encourages bushier growth. Geranium reflexum Andrews grows low to the ground, and pruning back the tips will help promote fullness and compact growth.
Propagation of Geranium reflexum Andrews
Geranium reflexum Andrews, commonly known as heath-leaved cranesbill, is a hardy and drought-tolerant perennial plant that can be propagated through several methods. The following are the primary propagation methods for this plant:
Seed Propagation
Seed propagation is one of the most common methods for growing Geranium reflexum. The seeds can be sown directly in the garden in spring or fall, or they can be started indoors in late winter. To start the seeds indoors, fill a seed tray with a moist potting mix, sow the seeds thinly, and cover with a thin layer of soil. Keep the soil moist and warm, and the seeds should germinate within two to three weeks. Once the seedlings are big enough to handle, transplant them into individual pots and then into the garden when they're large enough to handle.
Cuttings Propagation
Geranium reflexum can also be propagated through cuttings. The best time to take cuttings is in late spring or early summer when the plant is actively growing. Take a cutting of about 3-4 inches long, remove the leaves from the lower part of the stem, and dip the end of the cutting in rooting hormone powder. Insert the cutting into a pot filled with moist potting mix, cover it with a clear plastic dome to retain moisture, and place in a warm, bright spot. Keep the soil moist, and the cutting should develop roots within a few weeks. Once the roots have formed, transplant the cutting into the garden.
Division Propagation
The division method is another option for propagating Geranium reflexum. This method involves digging up an established plant in early spring, dividing the root ball into several pieces using a sharp knife or spade, and then planting each division in a new location. Make sure that each division has enough roots to survive on its own and that the soil is moist and well-drained. Water the newly planted divisions and keep the soil consistently moist until they are well-established.
Disease and Pest Management for Geranium reflexum Andrews
Geranium reflexum Andrews, commonly referred to as Heath-leaved Cranesbill, is a perennial plant suitable for gardens due to its excellent ground cover abilities, its attractive foliage, and its showy flowers. While it is usually low maintenance, it can become susceptible to a wide range of pests and diseases, which can cause its demise. Here are some common diseases and pests that might affect the plant and suggestions for managing them:
Common Diseases
Gray Mold (Botrytis cinerea): This disease is characterized by the appearance of gray, fuzzy mold on the leaves, stems, and flowers. It is usually caused by high humidity and damp conditions. To manage this disease, remove all the infected parts and discard them as soon as possible. Maintain excellent air circulation to reduce humidity, and avoid overhead watering.
Root Rot (Pythium spp.): This disease is caused by a soil-borne fungus that damages the roots, causing them to rot. It can be recognized by yellow leaves that slowly wilt before eventually turning brown and dying. To manage this disease, ensure you plant in well-draining soil and avoid overwatering.
Leaf Blight (Alternaria spp.): This disease causes the leaves to develop brown spots, which gradually expand to cover the whole leaf. The plant may also experience premature defoliation if left untreated. The best way to control this disease is by removing all the infected leaves and destroying them. You can also apply fungicides to protect healthy leaves from becoming infected.
Common Pests
Slugs and Snails: These gastropods feed on the leaves and stems of the plant, causing extensive damage. To manage them, you can apply snail bait or use traps like shallow containers filled with beer, which attracts the slugs and snails and causes them to drown. You can also reduce their habitat by keeping your garden free of debris and weeds.
Aphids: These tiny, sap-sucking insects can cause severe damage to your plant, stunting growth and causing leaf curling. To manage them, you can blast them away with a strong stream of water or use neem oil, insecticidal soap, or horticultural oil to control them.
Spider Mites: These minuscule arachnids feed on the underside of leaves, causing them to become mottled and discolored before finally falling off. To manage them, you can remove the affected leaves and destroy them. You can also introduce natural predators like ladybugs or apply insecticidal soap or horticultural oil.
By monitoring your Geranium reflexum Andrews and taking measures to prevent or manage pests and diseases, your plant will thrive, adding beauty to your garden for years to come.
