Pennywort is a popular marsh plant that grows quickly and produces pretty yellow flowers. When it's in the aquarium, the winter cold isn't a problem. But what's it like outside on the bank of a pond or in a window box?

Pennywort can handle sub-zero temperatures very well

Pennywort is completely hardy

According to experts, this fast-growing ground cover can withstand temperatures down to -35 °C when planted out. This makes the plant suitable for both mild and harsh areas of our country. She also doesn't need any precautions to protect her from frostbite, so she can be left to her own devices.

Dry damage is possible

Even if pennywort is hardy, it can still be damaged in winter. On dry, sunny winter days there is a risk of frost. Dry damage to the shoots also occurs if the crop is not protected by a layer of snow.

If pennywort is planted in a sunny spot, you should shade it in winter. For example, by covering it with a thin layer of brushwood.

tips

If parts of the pennywort have not survived the winter unscathed, there is no reason to despair. Cut back the plant early in spring. It will sprout again soon after.

pruning and winter hardiness

Some gardeners shy away from keeping the garden "clean" in the fall. The above-ground parts are also cut off from pennywort. This does not diminish its survivability in the approaching cold season. In addition, the plant tolerates pruning all year round.

However, ecological reasons speak in favor of postponing the pruning until spring. Because the dense evergreen foliage of the pennywort is a sought-after winter quarters for many insects.

care in winter

Not much care is required during the winter. Only the water balance must be kept in mind. As a swamp plant, pennywort requires moisture all year round. Continue watering as needed, if only on frost-free days.

Tub specimens overwinter

Pennywort is not only a sought-after marsh plant for the shore zone of a garden pond. It also grows decoratively in balcony boxes or pots and maintains its long flowering period from May to August.

Planters outside in winter must be protected from frost. Wrap the jar in foil, plant fleece or reed mats and place it on insulating styrofoam. Its winter location should be protected as much as possible. If it is not covered, tilt the pot slightly so that excess rainwater can drain off.
