Please share your examples. At The Arboretum at Flagstaff our garden soil was volcanic, but we had many rare species that required limestone soil.  We created a limestone mound along a planned garden path to support several rare limestone species in the region.

Looking at the types of horticulture practice that we may want to present in the Horticulture best practices in the Propagation sub-section, we plan to have seed, cuttings, propagating from division and we could have grafting or layering.  Is the latter used for rare plants?  Can you please share your examples?

Our summer fellow pointed me in the direction of this interactive platform for seed germination analysis. I can see it being a useful instrument for producing visualizations for reports if can make the fields fit your needs.

Apologies for cross posting (this is why we need an announcements channel :)), but the CPC National Meeting Videos are ready for viewing in the PI Portal. They will be moved to plant nucleus in our next phase of development (coming soon!). Take a sneak peak at Cheryl's

According to the attached review of germination data analysis (McNair et al. 2012), time to event analysis (survival analysis) is the recommended approach for analyzing germination data. Does anyone know of a study that incorporates phylogeny as a covariate in a survival analysis?

I'm new to germination testing and will be running germination trials on lots of different species (mostly midwest natives). What kind of plates/containers do you use? What kind of media- agar, blotter paper, sand?) do you use and what do I need to know about keeping it watered/sterilized/labeled?  Do you always steralize your seeds before "planting" them? If so, what protocol do you follow? Please share your trials and tribulations! Thanks!

We are looking to propagate seeds from several Lapanthes species via micropropagation - if anyone has experience and protocols we would appreciate hearing from you.  We are working with several species, listed below, but we are looking for general information also.   Lepanthes eltoroensis Lepanthes rupestris Lepanthes woodburyana Thank you!

We germinated seeds of Goodyera in tissue culture with great success. Once they had 3 to 4 leaves in a test tube, we planted them in the greenhouse. However, they rapidly declined. We have tried planting them both in our usual potting mix (containing compost and topsoil) and New Zealand sphagnum moss. Any thoughts or suggestions?

Does anyone have experience with seed treatments and/or tips for germination of Solidago squarrosa?
