Customer reviews

Rated 5.00 out of 5 based on 12 customer reviews for Sweet Flag.

Rated 5 out of 5. Gentle, grounding, and well packaged I’ve been really impressed with the Sweet Flag from Mudbrick Herb Cottage. The quality is excellent — fresh, fragrant, and clearly handled with care. I popped these in a pot and put them in a bird bath outside my door and it has this calm, earthy feeling that instantly makes my space feel more grounded and quiet. What I love most is how thoughtful everything feels, from the product itself to the communication. You can tell they are grown by people who actually care about herbs and the people using them. I highly recommend Mudbrick Herb Cottage for anyone who values quality and a gentle, positive experience. Amanda Layer , May 2026.
