Euphorbia paralias aka Sea Spurge

Taxonomy

Euphorbia paralias, commonly known as sea spurge, is a species of flowering plant in the family Euphorbiaceae. Native to Europe, northern Africa, and western Asia, it has also been widely naturalized in Australia. This invasive species poses a threat to coastal areas, displacing local plants and colonizing open sandy areas that are preferred nesting sites for certain bird species. To combat its spread, eradication programs have been successfully implemented, such as the efforts of the Sea Spurge Remote Area Teams in Tasmania. Sea spurge is a succulent sub-shrub that typically reaches a height of 70cm. Its upright stems are adorned with small, bluish-green leaves and terminal clusters of green flowers. Although it is native to Britain and exclusively found on sand dunes, it has become a problematic invader in other regions. Interestingly, sea spurge can also be grown as a rare houseplant. Thriving with minimal water, it prefers long-lasting direct light and should be positioned within one foot of a window. The plant thrives in extremely well-draining soil and does not require additional fertilizers if repotted each time it doubles in size.

How to care for Sea Spurge

Water

Sea Spurge does best in dry soil and should only be watered sparingly.

Soil

The Sea Spurge is delicate when it comes to soil that is too damp, therefore, it is crucial to select a potting soil that has efficient drainage and doesn't hold an excessive amount of moisture. An ideal soil should consist of a substantial amount of perlite or vermiculite for proper drainage and some organic matter for nutrition. Mixing a few handfuls of perlite with commercially available cactus soil should produce the desired result.

Lighting

Sea Spurge requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Sea Spurge will be sure to bring you many years of beauty and enjoyment.

Dormancy

During the cold period, it is common for Sea Spurge to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Toxicity

Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.

Humidity

Sea Spurge thrives in dry environments, but if you provide extra humidity or mist your plant, the lingering water on its leaves could create an ideal environment for certain fungal diseases.

Fertilizer

The growth of Sea Spurge is gradual and it doesn't necessitate any additional fertilizers. Replacing the soil in its pot once a year should suffice to provide the plant with sufficient nutrition. It's important to keep in mind that plants derive their energy from the sun's rays, not fertilizers.

Region of origin

Sea Spurge’s native range is Worldwide.
