The source in Torah is from vayikra ch 19 verse 19
You shall observe My statutes: You shall not crossbreed your livestock with different species. You shall not sow your field with a mixture of seeds, and a garment which has a mixture of shaatnez shall not come upon you.
יטאֶת־חֻקֹּתַי֘ תִּשְׁמֹ֒רוּ֒ בְּהֶמְתְּךָ֙ לֹֽא־תַרְבִּ֣יעַ כִּלְאַ֔יִם שָֽׂדְךָ֖ לֹֽא־תִזְרַ֣ע כִּלְאָ֑יִם וּבֶ֤גֶד כִּלְאַ֨יִם֙ שַֽׁעַטְנֵ֔ז לֹ֥א יַֽעֲלֶ֖ה עָלֶֽיךָ
(translation from chabad.org)
What exactly is the name of the prohibition of to "not sow your field with a mixture of seeds"?
Is this prohibition just the creation of a plant/tree or does it also apply to eating, growing, or benefiting as well?
If a Jew bought a hybrid plant/tree could he plant it or would he have to get rid of it? Would knowledge of the plant being a hybrid make a difference? For example if he didn't know it was a hybrid would he then have to remove the plant after the fact?
