The Pelargonium barklyi is an attractive geophytic plant (with underground storage organ) that grows from a big tuber and can reach heights of up to 19 inches. During the winter, it produces enormous heart-shaped leaves that differ in shape and size from plant to plant. The leaves are the main reason it is growing; they are really pretty. 

The top of the leaf has a light green color, is hairy, and is covered in deep veins, with dark purple areas frequently around the veins. The leaves have a rich purple underside. During the summer, the plant goes dormant and has no leaves. Because its leaves are so distinctive, Pelargonium barklyi is unlikely to be confused with any other species that has tuberous underground sections. 

The flowers of Barkly's pelargonium are a true delight, showcasing vibrant shades of creamy white, with delicate petals that form a lovely cluster. Barkly's pelargonium produces charming blooms during the late winter to early spring, creating a burst of color in your garden or indoor space. 

The Pelargonium can be propagated through stem cuttings. Simply take a healthy stem cutting, remove the lower leaves, and place it in a well-draining potting mix. Keep the soil lightly moist until roots develop, and then gradually acclimate the new plant to its desired location. 

Watering Needs 

When it comes to watering the Pelargonium, it prefers to be kept slightly on the drier side rather than constantly moist. Overwatering can lead to root rot and other issues, so it's best to allow the top inch of the soil to dry out between waterings. Stick your finger into the soil to check the moisture level. It is time to water if it feels dry at that depth. 

In the spring and summer, during the active growing season, the Pelargonium barklyi appreciates regular watering. However, it's important to avoid waterlogging the soil. A good rule of thumb is to water deeply but sparingly. This means thoroughly saturating the soil until water drains out of the bottom of the pot, and then allowing the soil to dry out before watering again. 

In the fall and winter, during the dormant season, the Pelargonium plant's water requirements decrease. It enters a period of rest, so you'll want to reduce the frequency of watering. Allow the soil to dry out more between waterings but be sure not to let it completely dry out. A light watering every few weeks should be sufficient to keep the plant hydrated during this time.  

Light Requirements 

When growing indoors, the Pelargonium barklyi thrives in bright, indirect sunlight. Place it near a window so it can get plenty of bright, filtered light all day. It should not be placed in direct sunlight, as this could scorch the foliage. If you notice that your Pelargonium plant is stretching towards the light or the leaves are turning pale, it might be an indication that it needs more light. Consider moving it to a brighter area or supplementing it with artificial grow lights. 

When growing outdoors, your Pelargonium loves to bask in the sun outdoors! It prefers full sun or partial shade, so find a location in your garden where it can receive at least 6 hours of direct sunlight daily. This will promote healthy growth and colorful blooms. If you live in a hot climate, providing some afternoon shade can help protect the plant from intense heat. Just make sure it still gets enough sunlight to thrive. 

Remember, every plant is unique, and light requirements can vary slightly. Keep an eye on your Pelargonium barklyi and observe how it responds to light conditions. 

Adjust the lighting accordingly to ensure your Pelargonium barklyi is getting the right amount of light to flourish.   

Optimal Soil & Fertilizer 

The Pelargonium favors very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized succulent potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your Pelargonium succulent to thrive. 

The Pelargonium barklyi appreciates minimal feeding during the growing season in the spring. You can use a balanced (5-10-5), water-soluble NPK fertilizer. Dilute the fertilizer according to the instructions on the package and apply it once a year. Be sure to water the plant before fertilizing to prevent any potential root burn. 

During the dormant season, which is usually in fall and winter, you can reduce the frequency of fertilization to once a month or stop altogether. This allows the plant to rest and prepare for the next growing season. 

Remember, it's always a good idea to monitor your plant's response to fertilizers. If you notice any signs of fertilizer burn, such as yellowing or wilting leaves, reduce the amount of fertilizer or dilute it further. And as always, follow the instructions on the fertilizer packaging for the best results.  

Hardiness Zone & More 

When growing indoors, the Pelargonium barklyi is generally well-suited to average room temperatures. It prefers temperatures between 60°F and 75°F. It's important to avoid exposing the plant to extreme temperature fluctuations or drafts, as this can cause stress and damage to the leaves. The Pelargonium barklyi can tolerate a range of humidity levels, but it generally prefers moderate humidity. If the air in your home is too dry, especially during the winter months, you can increase humidity by using a humidifier or placing a tray of water near the plant. 

For outdoor cultivation, the Pelargonium barklyi is typically suitable for USDA hardiness zones 10-11. It thrives in warm and temperate climates. If you live in a region with colder winters, you can still enjoy this plant outdoors during the warmer months. Just make sure to bring it indoors or provide protection when temperatures drop below your preferred range.  

As for temperature, the Pelargonium barklyi enjoys warm weather and can tolerate temperatures up to 90°F or higher. However, it's important to provide some shade or protection from the intense midday sun, especially in hotter climates.  

Remember, these are general guidelines, and individual plant preferences can vary. It's always a good idea to observe how your Pelargonium barklyi responds to the specific conditions in your home or garden and make adjustments accordingly. By providing the right temperature and humidity, you'll help ensure the plant's overall health and well-being.
