Instead of writing about seeds, I was in collecting them ;) therefore a combined post about Chamaedaphne calyculata, the Leatherleaf or ground laurel.
The sole member of the genus Chamaedaphne (Ericaceae), leatherleaf is a low growing evergreen small shrub (up to 1.5 m tall). It is native to cool regions of the Northern Hemisphere, from North America, NE Europe to N. Japan, Mongolia and Siberia, where grows in all types of bogs, sedge fens, and open wetlands.
It is characteristic of mature and late stages of moss shrub communities, where it forms colonies, with rhizomes spreading in the sphagnum moss. It actually helps the installation of other species with whom is found growing, like Sarracenia, Drosera, Kalmia polifolia, Ledum groenlandica, various Vaccinium species.
The common name comes from the thick, leathery leaves, which are turning red-brown in the winter. It has a dense branching and the older stems turn gray with a fine exfoliating bark texture.
The white, bell shaped flowers on long inflorescences appear in April-July, depending on the region. Somewhat resembles Andromeda flowers, which is why Linnaeus first named it Andromeda calyculata.
Fruits are capsules with split open and release the seeds shown below (wedged shaped, golden brown).
It would make a great addition for small and large bog gardens. For those who have conditions and enjoy growing Ericaceous species – the seeds require cold/moist stratification and probably best to germinate them like in nature on a piece of sphagnum moss (in a pot/or ‘in situ’). I showed in a previous post how to easily germinate Gaultheria procumbens and Saxifraga cuneifolia in moss (Read here Sowing in moss).
