I guess it depends on your definition of "continent". We know that this here is the full landmass of the game. https://cdn.discordapp.com/attachments/441573352197324801/918540425936121876/SPOILER_Complete_Map_without_Markers.png
Every seed is located somewhere within this map. There's some bigger islands in there but nothing I would personally call a "continent".
