## Quick answer

Yes. Calendula — pot marigold, Calendula officinalis — is on RVC's safe Wild Garden Herbs/Weeds/Flowers list. The orange flower heads and petals are the part people pick, and the plant has a long history as an edible flower.

The register is the standard wild-herb shape: RVC lists it, the sweep found nothing against it, and no feeding study of calendula in guinea pigs exists. Our recommendation: petals in small rotated amounts, with one naming caution the FAQ covers — the "marigold" label covers more than one plant.

## Is calendula good for guinea pigs?

Calendula fills the flowers slot of the weeds-and-herbs band — the fresh 10–15% of the diet on the RVC factsheet. Petals bring color and foraging interest to the bowl, which is a real enrichment gain even with no nutrient register behind them.

The register holds no vitamin C or mineral figures for calendula, so it does not count toward the 10–30 mg of vitamin C guinea pigs need daily. Treat the petals as a rotating accent, not a nutrient source.

## How to feed calendula

Pick flower heads or loose petals from unsprayed plants — garden rows or pots that have never seen pesticide, since florist and bedding-plant flowers are routinely treated. Rinse, then serve fresh and raw.

A pinch of petals is a serving; this is an accent plant. First time, watch the usual next-day droppings, then let it rotate through the forage slot with the leafy herbs.

## Frequently asked questions

**Q: Can guinea pigs eat calendula petals?**

Yes — the petals and whole flower heads are the usual picked part, and the RVC listing covers the plant with no part qualification. Fresh, raw, unsprayed, in small rotated amounts.

**Q: Is calendula the same as marigold?**

This is the name trap on this page: pot marigold (Calendula officinalis) is the plant on the RVC list. The bedding plant most gardens call marigold is Tagetes — a different genus. The register names Calendula; RVC's "confident in identification" rule is the tiebreaker at the flower bed.

**Q: Can guinea pigs eat dried calendula flowers?**

Dried calendula is a common small-pet forage topping, and drying does not change the register status of the plant. Feed it like any dried herb — a pinch in rotation, no more "because it is dry".

**Q: How much calendula can a guinea pig have?**

A pinch or two of petals, a few times a week at most — it is an accent inside the fresh portion, not a salad. Flowers rotate with the leafy weeds and herbs rather than replacing them.

## Safety notes

Introduce any new food gradually: a small taste at first, building up over a week or so, and keep every serving fresh and raw. Hay stays the main event at around 80% of the day's eating, with fresh vegetables as the supplement.

**When to contact your vet**: Guinea pigs hide illness well. Contact your vet promptly if your guinea pig stops eating or passes fewer droppings, seems lethargic or in pain, has diarrhea, or shows any sudden change in behavior — small pets go downhill fast, and same-day advice is always the safe call.
