If I plant a SoapNut will it grow?
No, the SoapNut used for washing is the berry casing, which has been dried and deseeded. Occasionally you may find a seed still attached to the berry in your bag of SoapNuts- it is a small, black, and hard, it looks like a solid blueberry. If you find one soak it overnight in warm water and then plant into seed mix and keep damp, warm and in bright light, it will take time to germinate but you can grow yourself a SoapNut tree.
