Caltha palustris Marginal Pond Plant

Caltha palustris brings early, dense yellow flowering to the pond margin, giving colour before many other marginal plants have got going. A slow-growing native plant, it suits shallow planting pockets or the pond shelf and needs little dividing once settled. Choose a single potted plant in a 1 litre or 3 litre basket, or a pack of three 9cm potted plants for covering more ground.

Caltha palustris is a native marginal pond plant that, once established, flowers so heavily in early spring it can look like a solid ball of yellow blossom. It suits pond keepers planting the shallow margins or shelf area of a pond, and gives colour at a time when many other marginal plants have barely started growing.

You get a single plant already potted in a mesh aquatic basket with the 1 litre and 3 litre sizes, or three individual plants each in a 9cm pot with the pack option. The smaller pot size is a useful way to cover more planting area without buying several larger baskets.

The plant tolerates full sun through to part shade, so there is some flexibility in where it goes around the pond edge. It is slow-growing too, meaning it will not need dividing or cutting back as often as some faster-spreading marginals.

Its mature size keeps it in scale with smaller pond margins and planting pockets, so it is unlikely to crowd out neighbouring plants once settled.
