Sea Holly, also known as Eryngium, is a delightful addition to any garden or landscape. One of the primary concerns many gardeners have when considering planting Sea Holly is its invasive nature. However, I am pleased to inform you that Sea Holly is not invasive like many other thistles. It is a well-behaved plant that will not take over your garden.
Unlike its thistle relatives, Sea Holly does not spread aggressively through seeds or underground runners. This means that once you plant it in your garden, you can rest assured that it will not overrun your other plants or become a nuisance. This is especially important if you have a small garden or limited space.
The ornamental qualities of Sea Holly are what make it such a desirable plant. Its foliage comes in a variety of stunning colors, ranging from silver and green to blue, purple, and even white. These unique hues can add a touch of elegance and intrigue to any garden or landscape design.
In addition to its beautiful foliage, Sea Holly also produces intriguing flower heads. These flower heads are composed of small, spiky blooms that can range in color from vibrant blue and purple to white or even yellow. These flowers are not only visually appealing but also attract pollinators such as bees and butterflies, making Sea Holly a valuable addition to any pollinator garden.
Personally, I have had the pleasure of growing Sea Holly in my own garden, and I can attest to its non-invasive nature. I found that it remained contained within the designated area and did not encroach on neighboring plants. Its unique foliage and striking flowers added a lovely touch to my garden, and I received many compliments from visitors.
To summarize, Sea Holly is not invasive like many other thistles. Its ornamental qualities, including its colored foliage and striking flowers, make it a desirable addition to any garden or landscape. It is a well-behaved plant that will not spread aggressively or take over your garden. So, if you are looking for a low-maintenance, visually appealing plant, Sea Holly is an excellent choice.
