In my perpetual search for a white plant, the Lagenandra thwaitesii just may really strike an accord. Does anyone have practical experience with this species? Does it retain the beautiful white edges when submerged?



Other images of this plant lack the attractive white outline. What could account for such drastically different variations?

As always, my thanks.

I've got what I think is L. thwaitesii (it hasn't flowered yet) growing in the a greenhouse. It's done best in a well drained pot with soil. In the past I've had it in a clay based substrate in a small indoor stream feature as well as in the above soil with a self-watering dish under the pot. As soon as I took the dish away and let the pot drain after its daily watering new leaves started growing. I'm hopeful that it will flower sometime this summer.

After trying the different types of substrates and growing conditions I'd have to make the guess that these plants prefer a loose substrate with decent circulation. They may be a good candidate for undergravel heating as well.

Best,
Phil

Thank you for the information Phil. Have you tried growing it submersed yet?

Not yet, it's still trying to get used to growing again. Once it's big enough for me to split it I may try it submersed, it's a BIG plant though. We'll see.

Best,
Phil

Hi Phill,

Large plant? Mine never got very big at all - about the size of an emergent growth C. wendtii.

Do you have L. ovata? Now that is a large plant.

I think the white edges are an artifact of the photo media used and the lighting. Mine don't have white edges. What makes us think it should have white edges?

I could have any species to tell the truth, I got it at a club meeting and have forgotten the species and have no label. That's why I want so badly to flower it. Right now the tallest leaf is on an 8" petiole and the leaf itself is 4-5" long.

Looking at the leaves on that plant it looks as though they have a darker, glossy, green center portion and a lighter outer rim. That may be why it's supposed to have those white edges.

Best,
Phil

Phil, a plant this size sounds more like L. ovata - the only other Laganandra commonly offered or even seen here in the Western Hemisphere.

It could be something else, but odds are it's ovata. No Lag. t. I've run across was ever THAT big!
