Zebra grass, scientifically known as Miscanthus sinensis, can indeed propagate by seed. If you are interested in growing this beautiful ornamental grass in your garden, there are a couple of ways you can go about it. One option is to sow the seeds in pots in a cold frame during the spring. This method allows you to control the growing conditions and gives the seeds a good start before transplanting them into your desired location.
Another method of propagation is through division, which is typically done in the spring. This involves carefully digging up an established clump of zebra grass and dividing it into smaller sections. Each section should have a good amount of roots and shoots, ensuring that it has the potential to grow into a new plant. These divisions can then be replanted in your garden, allowing the zebra grass to spread and fill out the desired area.
It is worth mentioning that while zebra grass is a beautiful addition to any garden, it is important to be aware of its invasive potential. The species form of Miscanthus sinensis is considered invasive in several US states. This means that if left unchecked, it has the potential to spread aggressively and outcompete native plants. However, many of the ornamental cultivars of zebra grass are sterile, which means they do not produce viable seeds. This greatly reduces their invasive potential and makes them a safer choice for gardeners.
In my own experience, I have grown zebra grass from both seeds and divisions. Sowing the seeds in pots in a cold frame allowed me to closely monitor their growth and ensure they had the best possible start. Once they were large enough, I transplanted them into my garden beds and watched as they established themselves and added a touch of elegance to my landscape.
I have also divided established clumps of zebra grass to create new plants. This method is particularly useful when you want to expand the presence of zebra grass in your garden or share it with friends and family. By carefully dividing the clump into smaller sections, I was able to create multiple new plants that thrived in their new locations.
Zebra grass can spread by seed if allowed to, but the invasive potential is of less concern for many of its ornamental cultivars. Whether you choose to start from seeds or divisions, this beautiful grass can bring a unique and striking element to your garden. Just be sure to monitor its growth and take necessary precautions to prevent it from becoming invasive in your area.
