Euphorbia cylindrafolia var. tuberosa

Euphorbia cylindrifolia var. tuberosa, commonly known as tuberous cylindrical spurge, is a variety of the Euphorbia cylindrifolia plant. It is a succulent perennial that belongs to the Euphorbiaceae family. Here’s a description of Euphorbia cylindrifolia var. tuberosa:

1. Appearance: Euphorbia cylindrifolia var. tuberosa has a unique and striking appearance. The plant features cylindrical stems that grow upright or slightly sprawling. The stems are typically green in color and have prominent ridges or ribs along their length. They can grow to be several inches long.
2. Tubers: The variety name “tuberosa” refers to the presence of tuberous structures at the base of the stems. These tubers serve as storage organs, allowing the plant to survive periods of drought or stress. They are usually rounded or elongated and can be partially or fully buried in the soil.
3. Leaves: Euphorbia cylindrifolia var. tuberosa has small, succulent leaves that are reduced in size and often ephemeral. The leaves are typically clustered around the stem tips or are found at the base of the plant. They may be green or have a bluish-green hue.
4. Flowers: The plant produces small, inconspicuous flowers that are often not the main ornamental feature. The flowers are typically green or yellowish-green in color and are borne in clusters at the top of the stems. The flowering period can occur in spring or summer.
5. Growth Habit: Euphorbia cylindrifolia var. tuberosa has an upright or slightly sprawling growth habit. It can form dense clumps over time as new stems emerge from the base of the plant. The stems may branch sparingly, creating a bushy appearance.
6. Cultivation: This succulent is relatively low-maintenance and well-suited to arid or drought-tolerant gardens. It prefers well-draining soil and requires minimal watering, as overwatering can lead to root rot. Euphorbia cylindrifolia var. tuberosa is also adaptable to a range of lighting conditions, from full sun to partial shade.

It’s important to note that Euphorbia species, including Euphorbia cylindrifolia var. tuberosa, contain a milky sap that can be toxic and irritating to the skin and eyes. When handling or pruning the plant, it’s advisable to take precautions and avoid contact with the sap.
