African Ocotillo

The African Ocotillo, scientifically known as Euphorbia tirucalli, is a unique and visually striking plant, often sought after for its architectural qualities. Native to Africa, this plant can grow quite tall, reaching up to 20 feet in height, with a spread of 4 to 6 feet.

The African Ocotillo is characterized by its pencil-thin, green, cylindrical branches, which grow vertically and branch out from the main stem. This growth habit gives it a sparse, tree-like appearance. Its branches contain a milky sap that is toxic and can be irritating to the skin and eyes, so caution should be exercised when handling this plant.

One of the distinctive features of Euphorbia tirucalli is its lack of traditional leaves. The plant performs photosynthesis through its green branches. This adaptation makes it highly suited to arid environments and an excellent choice for xeriscaping.

Although not a frequent bloomer, when it does produce flowers, they are small and red, adding a subtle pop of color. The African Ocotillo thrives in full sun, which encourages robust growth and contributes to its overall health.

This plant is suitable for large, open landscapes where its height and unique form can be appreciated. It is also popular as a container plant for patios or indoors, where it adds a dramatic and sculptural element. Due to its drought tolerance and minimal maintenance requirements, it is a popular choice for gardens in dry climates and for gardeners seeking low-maintenance, high-impact plants.

Planting Guide:

• Location: Full sun (at least 6 hours of direct sunlight daily)
• Soil: Well-drained, sandy or gravelly soil (avoid heavy, clay-based soils)
• Spacing: Space plants 6-10 feet apart to allow for mature growth and proper airflow
• Planting Depth: Plant at the same depth as the root ball, ensuring the top of the root ball is level with the surrounding soil surface
• Support: No support is typically needed. This plant is well-suited to arid conditions and can thrive in exposed areas.

Watering Guide:

Watering After Planting:

• Initial Watering: Water thoroughly immediately after planting to saturate the root ball and surrounding soil
• Frequency: Water every 2-3 days for the first 2 weeks, depending on weather conditions and the soil’s moisture retention
• Watering Amount: Provide about 1 inch of water per session to ensure deep watering and proper root establishment

When is the Plant Established?

• Timeframe: The African Ocotillo is considered established after 2-3 months when the roots have spread and the plant begins to show consistent new growth

Watering Once Established:

• Summer: Water every 10-14 days during the hotter months, ensuring the soil is thoroughly moistened. Provide about 2 inches of water per session.
• Winter: Water every 3-4 weeks, depending on rainfall. The African Ocotillo can tolerate drought and requires minimal watering during winter dormancy.

General Watering Tips:

• Soil Check: Regularly check soil moisture. Water when the top 2-3 inches of soil are dry to the touch.
• Avoid Overwatering: The African Ocotillo is drought-tolerant and thrives in dry conditions. Overwatering can cause root rot.
• Mulch: Apply mulch sparingly around the base of the plant to retain moisture but avoid letting it touch the plant’s trunk.
