Reference for Ketubot 157:13

אבא זרדתא ופירא דכוורי אמרי לה פירא ואמרי לה קרנא כללא דמילתא גזעו מחליף פירא אין גזעו מחליף קרנא

[What, however, is the ruling if the husband desires to purchase] a thicket of sorb or a fish pond? Some maintain that it is regarded as produce; and others maintain that it is regarded as capital. This is the general rule: If the stump grows new shoots it is regarded as (capital) produce, but if the stump grows no new shoots it is regarded as (produce) capital.
