Growing a Nepenthes Terrarium

Look what my spouse brought home for me yesterday as a gift for being sick. If this is what I get for being sick what do I get for being a fully-functioning, productive member of society? Actually being sick was a nice excuse to lay in bed watching Wonder Woman reruns and re-reading back issues of Bitch Magazine until today, the forth day, which just happens to be one day too long. I am both exhausted and bored out of my skull. Those last days of summer are passing me by while I sleep all day, wallowing in my own unshowered filth.
But this is not about being sick, this is supposed to be about the plant. When he presented me with this Nepenthes ventricosa all fancified in a perfect little box, complete with tissue paper and ribbon I have to admit that after the initial excitement and flattery my “thriftiness” (read cheapness) kicked in and my second thought was “But I could have put this together myself for about ten bucks!” I haven’t asked him how much it actually cost. I don’t want to know. Knowing might kill me if this unknown virus or utter boredom doesn’t first.

If you want to make something like this easily and without gift-store/fancy-pants floral shop prices here’s what you do:
1. Get yourself a pretty glass bowl, fish bowl, candy bowl or terrarium. Department stores sell them in the pet section and so do thrift stores.
2. Line the bowl with approximately 2-3 inches of gravel. This can also be purchased cheaply in a pet store. Gravel is inexpensive when purchased from the pet department. Repackaged as floral gravel and the price is jacked sky high. Go figure.
3. Add about 2 inches of long fiber sphagnum moss to the bowl. Remove the small Nepenthes plant from it’s pot and plant into the sphagnum. Personally I am not a fan of pure sphagnum as the “soil” for this plant. The Nepenthes will certainly survive since the sphagnum provides a light and airy bed that doesn’t stay too damp just as Nepenthes’ roots require, however the sphagnum can dry out too easily if you don’t watch it like a hawk. Try the following instead:
Nepenthes Soil Mix
-
Mix together:
- 1 part long fiber sphagnum moss
- 1 part orchid bark mix
- 1 part regular peat or coir
Quick Nepenthes Growing Tips:
Nepenthes do not like wet feet — let the water in the gravel dry out just a little before adding more.

Sorry to hear you are sick, but you did luck out with the plant! You gave some great info and I’m going to look into getting myself one of these. They are beautiful and I love carnivorous plants… and I want one!
Hope you are feeling better soon!

How sad that you are sick at the end of summer!! I hate being sick any time the temperature is over zero celsius!
I wanted to ask you about the gravel you speak of: when you say it can be acquired from the pet store do you mean fish tank gravel, or kitty litter? Thanks - I love your site!

I’m actually going to hear Peter D’Amato speak at the Atlanta Botanical Garden about carnivorous plants in a couple of hours. I’ll have to pick up his book.
I’ve got a few glass bowls lying around that I need to do something with. Any other plants you’d think would work well in that situation?

That’s awesome cara. I would recommend a Sundew (Drosera) or two, or three for these little terrarium setups. The Nepenthes are great but they can grow to be quite large and will eventually need to live in a hanging basket. Sundews stay small forever and are just gorgeous.
You can also try Sarrancenia purpurea, the cold hardy pitcher plant that is native to my part of the world. They stay short enough for a terrarium.

I was really excited by this post because I’ve lately become obsessed with terrariums and can’t wait to start making my own. I’ve found that ebay has a lot of nice, inexpensive glass containers, apothecary jars, and the like.
Thank you for the info. Get well soon!

Oh yes I love apothecary jars. Here are a few more carnivorous terrariums I built for a gardening event last year.

I did a bromeliad terrarium as well but will have to dig up a photo.

Wendy: Sorry I missed your question. Definitely use fish gravel. It comes in all sorts of colours and is usually only $2-5 at most for the amount you will need for a small bowl.

hmm, actually, I bet that isn’t gravel at all at the bottom of your terrarium. It’s probably charcoal. charcoal’s supposed to help absorb the stinkiness that accumulates in undrained containers.

Flytrap: No it’s gravel. They didn’t put charcoal in this one.
I don’t think it is necessary with the nepenthes that dries slightly before rewatering but I do with the bog plants.

Hey there:
I have been painting the image of these pods in many ways for many, many years. The pods or pitchers they form are visually astounding! I finally got, as a gift, one of these wonderful plants. It is alive one year now! But all the pitchers dried up. It did very well hanging from a tree outside during the summer in NJ. It is back inside now but not growing any new pitchers, I would imagine because of the humidity problem. Is it fine that the cloche (when I get one) is open on top and still sufficient for humidity? My plant is pretty big and hanging (about 12 inches tall). The pitchers that were on the plant when I first received it hung down beyond the pot. Will planting in the cloche hinder the pitcher growth or happiness at all?
Thanks for response.

I had a flytrap but it died quick.:(

Danielle: Venus flytraps are not easy.
Tina: The trick is to get both humidity and air circulation so it is definitely important that the cloche is open at the top.

[…] Venus fly traps, on the other hand are easy to come by, sold as a novelty plants at fall fairs and the impulse sections of home renovation stores but I do not care for them, finding them particularly difficult to keep alive for more than a few months stretch. If you’re going to choose a carnivorous plant to grow on a windowsill I recommend little bitty sundews. I find them to be more forgiving than flytraps and their jewel-like, dew-speckled leaves are a whole lot more interesting too. […]
