Enchancement from https://bitbucket.org/binnie567/binnie-mods/issues/373/botany-vanilla-tree-saplings-can-be

Origin text:

Basically, Forestry is able to take unconverted vanilla tree saplings into its analyzer block and be able to scan them and turn them into converted forestry saplings. where as unconverted vanilla flowers can't go into said block. However converted botany flowers can go into the analyzer.

Sorry. This was fixed early. Bugreport is out of date.
