The plant arrived healthy and has grown well in my pond setup. The variegated leaves add a nice visual contrast. I keep the roots in water and the top part above, which matches the care instructions. It’s easy to maintain and looks great in the spring.

I planted it in a marginal zone with moist soil. The foliage has spread nicely over a few weeks. It doesn’t need extra CO₂, which is a relief. The color pattern is unique and stands out in the water garden.

Grew quickly in my outdoor pond. The plant adapts well to partial shade and stays green with white variegation. I appreciate the clear care instructions. No issues with root rot or leaf loss so far.
