Seeking input of plants safe for Pygmy Hippo enclosure
Hi everyone! I’m looking for advice from keepers, horticulturists, and anyone with experience managing browse or exhibit plants for pygmy hippos or other large browsing mammals.
I’ve been talking with a local Michigan zoo about donating plants for their pygmy hippo enclosure, which is currently very bare aside from a concrete pool. I’m not affiliated with the zoo—just a visitor who loves these animals and wants to support their wellbeing in a meaningful way.
The head keeper suggested options like hibiscus, non‑toxic grasses or ferns, sweet potato vine, bamboo (non‑invasive, cold‑hardy species), or potted tropicals that can be moved indoors for winter. I’ve had trouble finding mature bamboo this late in the season and am on waitlists for next year.
Because the zoo is in Michigan (Zone 5–6), I’m specifically looking for plants that meet all three criteria:
- Safe / non‑toxic for pygmy hippos
- Able to survive Michigan winters outdoors
- Tolerant of consistently wet or damp soil
I’d love to hear from anyone who has managed hippo habitats, wetland exhibits, or browse programs. What shrubs, trees, or perennials have worked well for you? What should I avoid? Any toxicity lists or horticulture resources your facility relies on would also be helpful.
I’m also hoping to confirm whether these plants meet the criteria above:
- Pennsylvania Sedge (Carex pensylvanica)
- Miscanthus ‘Gracillimus’
- Musa ‘Basjoo’ (cold‑hardy banana)
- Hibiscus Summerific ‘All Eyes on Me’
- Majesty Palm
- Sweet Potato Vine (Ipomoea)
Thanks in advance for any guidance or experience you can share!!
