Bog Garden Plants
| These Plant Profiles give a brief introduction to some of the more popular bog garden plants that are available for bog garden and waterside planting.These are plants that enjoy from moist, to very wet soil, but will not tolerate being waterlogged, especially during the winter months. A number are capable of tolerating periodic inundation, for in nature they often have to withstand excessive flooding from storms or spring snow melt.

Ligularia enjoys really moist soil, but not waterlogging.
|
Arctic plants, like Trollius, live in soil saturated from snow melt.
|
Not all bog garden plants are stream or pond-side plants, for in the wild there are swamps and bogs that are completely disconnected from water features. Sometimes these result from snow melt, or rain that is trapped in soil over impervious bed rock. In the case of Arctic plants, like the Globe Flower or Trollius, it may be associated with frozen soil well below the top layer of soil preventing water from draining away.

| However, most bog garden plants populate stream or riversides. The Astilbe and Filipendula species also spreading and colonising areas beyond the waterside fringes, and dwelling in the low meadowland areas that are constantly wet and periodically flooded. Here they often compete with, and complement, a thick carpet of grass, and so are excellent for planting in the garden in situations where they may need to accompany other low-growing subjects, for they are used to living in close harmony with other plants.

Filipendulas populate areas that are periodically flooded.
|
Gunnera manicata, produces enormous leaves.
|
Scale is also important in a bog garden, and not just the relationship of the bog garden or planted stream-side area to the pond or other water body.This can be amply demonstrated by the diversity within Gunnera. This group of plants, yields the contrasting tiny creeping species, such as G.magellanica, as well as massive ones like the Brazilian G.manicata.
|
However, the most diverse groups of flowering bog garden plants are the various Asiatic primulas. All will grow well in cool districts, making a spectacular spring and early summer display. The majority are candelabra types with their flowers arranged in whorls, although there are both drumstick and cowslip kinds available too.
