There is one Golden Seed location in the Siofra River region of Elden Ring. It is found under a glowing golden Erdtree sapling and can be reached relatively early by descending the Siofra River Well in eastern Limgrave (Mistwood).
Worshipper’s Woods Golden Seed
This seed sits under a golden tree on a cliffside ledge near the large castle-like structure on the northern side of the river, close to the lift that leads up to Caelid.
From the Worshipper’s Woods Site of Grace (near Hallowhorn Grounds), head north toward the massive stone structure.
Look for a narrow natural stone bridge crossing a gap. Cross the bridge carefully while watching for Ancestral Follower archers firing from above.
Once across, the golden sapling is on the left/uphill side near the cliff edge. The seed is at the base of the tree. You can also reach it easily from the Below the Well Site of Grace by heading southwest across the nearby ledges and supports.
Buff pierce resistance or use Torrent and stealth to make the bridge crossing safer. Minor enemies such as rats may be nearby, but no boss fight is required for this seed.
