Looking for a beautiful and unique aquatic addition to your garden pond? Look no further than the graceful Sparganium angustifolium, more commonly known as Narrow-leaved Bur Reed. This native plant, with its long, slender leaves and intriguing seed heads, is surprisingly easy to propagate.
For those unfamiliar, Sparganium angustifolium is a freshwater perennial plant that thrives in shallow water. It features long, narrow leaves that can grow up to 4 feet high and adds visual interest to any pond or water garden. One of its most distinctive features is its quirky seed head, which resembles a tiny, brown burr. This is where the “bur reed” name comes from.
But the real beauty of Sparganium angustifolium lies in its ease of propagation. Here’s a step-by-step guide on how to get this lovely plant growing in your pond:
1. Using Seed:
- Harvesting: In late summer or early fall, the mature seed heads will turn brown. Carefully collect these heads and allow them to dry in a cool, dry place. Once dried, gently rub the seeds out of the heads.
- Sowing: Direct sow the seeds into damp soil in your pond or water garden, ensuring the depth is no more than 6 inches.
- Patience: Seeds can take a little time to germinate, so be patient. Germination generally occurs in the spring.
2. Division:
- Choosing the Right Time: The best time to divide Sparganium angustifolium is in spring or early summer when the plant is actively growing.
- The Process: Gently remove the plant from its current location in your pond. Using a sharp knife or shovel, carefully divide the plant, ensuring each division has a good amount of roots and foliage.
- Replanting: Plant the divisions in a suitable location in your pond, ensuring the depth is no more than 6 inches.
- Care: Water the newly planted divisions well and be sure to provide consistent moisture.
