Do you need ideas about NA native woodland species to introduce into your garden? Take a hike into the woods; nature is the best expert in providing answers ;)

Trillium grandiflorum, the large white trillium and some of its companions are in flower right now and, with the current summer-like temperatures will not last long.
(other species not seen in the gallery: Erythronium americanum, Actaea rubra and A. pachypoda, Sambucus, Lonicera canadensis, Thalictrum dioicum, Hydrophyllum virginianum…)

Notes for the Seeds Shop

• The inventory of dry seeds will not be updated from now on (with the exception of two stage germinators: Lilium and Paeonia). This is the time to concentrate on the first seed collections, and most species, as it happens, require moist storage; it is a lot of work.
  Updates and new additions to the Seeds List will follow in late summer–early fall.
  
• Some Corydalis seeds have been collected; they will be available at the same time with the first Hepatica seeds in June. And fingers crossed that Claytonia virginica will also be available again this year.
• The collection of Hepatica seeds will most likely start at the end of the month/early June, and will be followed by Asarum, Stylophorum diphyllum and towards end of June: Sanguinaria canadensis and Erythronium americanum (if possible to collect).
  The availability of these species will be announced. They all require moist storage and are best sown right away.

This is how most Hepatica plants are looking at this time: new foliage has developed and the pedicels holding the fruit heads are hiding under the new leaves. This makes them hard to spot and is a good sign to keep in mind that the collecting has to be done soon.
Until the seeds are collected, I suggest a visit to the Hepatica page  where you can read more on the subject.
