North Carolina Botanical Garden has a little blurb on it in their latest newsletter What's Blooming - "sun/med, easy care, little-known large decidious shrub known for its yellow color and red berries, etc." but you probably already knew all that. :) But you might be able to get some additional info on it from them.

Here is a link that might be useful: NCBG

Hello Fellow Gardener ,
I was wondering how your Lindera Erythrocarpa is performing for you ?? As a 58 year old plant collector , I have been searching in earnest for this plant for a number of years and was wondering if that plant ever set seeds in it's location ?? I know the seeds lose viability very fast ( especially unwashed and dry stored ) but if it sets seeds so would you be willing to donate a few ?? If that is impossible could you possibly link me to any gardeners in your area that possess this plant ?? Currently I have Lindera obtusiloba , Linder benzoin , and Lindera angustifolia in our collection and all seem to be doing well.
I appreciate your time and input . Thanks again and HAPPY GROWING 2013 ! .
Please feel free to contact me :davidia6555NOSPAM@yahoo.com

I am still searching for FRESH lindera erythrocarpa seed so does anyone out there have any positive suggestions ??? TIA :)
