My night blooming cereus is about 7 years old and I have shared cuttings for years. I put it outside after the last frost and it has turned red – looks sunburned. I have kept it in the same spot for years and it blooms and seems happy there. Any idea what could have caused it to turn red? And will the green return?

Moving a plant from the indoors to outdoors without an adjustment period can cause the leaves to sunburn. You can move it to a shadier area for a week or so, then gradually increase the light. The burned leaves may fall off but should be replaced with new, green leaves.
