FAQ – Moist packed seeds
Many NA native species, especially spring flowering, are included in the ‘moist packed seeds‘ category (see also Corydalis & allies). By late spring this category is almost depleted of available seeds (with exception of Caulophyllum sometimes) because
the seeds not sold out during the fall/early winter season, will start to germinate in moist storage. You will find these species listed in green in the SEED LIST.
FAQ
Why are moist packed seeds not available year round?
- Because in the eventuality they are not sold out, they start to germinate in moist storage.
Even if large quantities were to be collected, shipping past due germination dates would not be possible.
- When do they start to germinate?
Depending on the species, it can happen as early as November (Paris quadrifolia and Asarum canadense) and December (Claytonia) and then gradually till February-March (most other species). In some cases ‘germination’ refers to roots only, with a another cycle of cold or warm/cold required for complete germination.
- When is it best to purchase moist packed species?
As soon as they are announced available in the Shop (please subscribe to the blog) or at any time before they start to germinate or temperatures drop below zero (in the winter), at which point they cannot be shipped safely.
To be on the sure side, I would consider June (for the first species available) and September/October/November ideal; these seeds are active physiologically and shipping them during deep freezes in the winter can be detrimental.
Various species with limited seeds on offer sell out fast (Claytonia, Hepatica forms) and it is best to buy them as soon as they are announced in the shop, starting in late May/June, (depending on the weather).
To facilitate a faster shipping (and easier sowing) the first such fresh seeds of the season are being shipped packed only in glassine envelopes. which are included in plastic bags (with no vermiculite). The method was tested and works very well for the month of June.
For this reason we usually have a ‘flash’ sale in June for Hepatica, Claytonia and Corydalis when you can purchase them slightly discounted. Hepatica seeds are sold in this manner ONLY for a short period after collecting.
