Euphorbia myrsinites, commonly known as myrtle spurge, is a plant that has a mixed reputation when it comes to invasiveness. In England, it has been recognized by the Royal Horticulture Society and awarded the prestigious Award of Garden Merit. This suggests that it is a plant of high quality and value for gardeners in that region.
However, in several western states of the United States, myrtle spurge is considered a noxious weed and is not recommended for planting. This is because it has been observed to have invasive tendencies, spreading rapidly and outcompeting native plant species. As a result, it can have negative impacts on the local ecosystem and biodiversity.
It is important to note that the invasiveness of myrtle spurge can vary depending on the climate and environmental conditions. In moister regions of the eastern United States, where it is less likely to become invasive, myrtle spurge can be a good addition to some gardens. Its unique succulent-like foliage and yellow flowers can add interesting texture and color to a landscape.
In terms of hardiness, myrtle spurge is suitable for zones 4-8, which covers a wide range of climates. This means that it can withstand cold winters and thrive in moderately warm summers. If you are considering planting myrtle spurge, it is advisable to check your specific hardiness zone to ensure it is suitable for your area.
It is worth noting that myrtle spurge contains a toxic milky sap that can cause skin irritation and be harmful if ingested. Therefore, it is important to handle this plant with caution and wear gloves when working with it. This is especially important if you have children or pets in your garden, as they may be more susceptible to accidental contact or ingestion.
To summarize, while myrtle spurge has been recognized for its merits in England, it is considered a noxious weed in several western states of the US. In moister eastern regions, it can be a good addition to some gardens, but caution should be exercised to prevent its invasive spread. It is hardy in zones 4-8 and should be handled with care due to its toxic sap.
