Lysimachia × producta is a hybrid of flowering plants in the primrose family Primulaceae.

[2] The hybrid specific epithet producta means "stretched out, extended",[3] a reference to the shape of its inflorescence.

[4] Lysimachia × producta has erect stems 4 to 10 dm (16 to 39 in) long.

The flowers are 5-merous with yellow petals, streaked with reddish or reddish-black markings.

The flowers of the hybrid and its parents are very similar but overall L. × producta more closely resembles L. terrestris since both have terminal racemes.
