This plant has been fun watching it grow. It has expressed numerous uncommon traits such as variegation and seeds that grow "naked" or without a calyx. Now it has sap forming on the butt end of one of the naked seeds! While you may have heard or seen sap secretions in certain varietals or under certain conditions. The sap is comprised of water and plant sugars. Why if forms is not fully understood. I have never seen this before until now. How did the seed excrete sap? How did the seeds become naked? Are the traits inheritable? Will we ever know? Probably not.
