U. fulva (Rock Hole, W.A.)

This bladderwort species, hails from Rock Hole, Western Austrailia.

It grows in shallow streams and can be found mostly submerged during the wet season there.

It flowers when the streams start to drop in flow and water level, as the dry season approaches.

This plant arrived to me as a small grassy looking plug about a year ago, and has been growing on a west facing window sill, that receives full sun from about 3:30 pm, until sundown.

It stayed on that west facing window sill all winter long, under about an inch of water, but by about February or early March, i was concerned that it might have perished because all of the photosynthetic leaf stolons had lost their greenness, were now yellowed or even whitish in color.

So I ordered a replacement, but by the time it arrived, the original fulva was beginning to liven up again, with the warmer and longer days approaching



The fact that it survived was welcome news.

I was just about to give the holding reservoir a complete water change, (to rid the pot's water of sunken algal-peat blobs, that float up to the surface when the sun heats the water and when bubbles are formed, they attach to plant debris, and up the blobs rise) but when I pulled the pot up from the water, I was surprised to find this hanging out from the pot's bottom.



With all of the water drained from the pot, the new green growth is now visible.



After that pic was taken, the pot was placed back into the old water, unchanged - just decided to let it be.

With the new sample, I decided to try growing it inside a warm humidity dome, under lights.

The clump was also placed closer to the surface level, with some growth emerging above water level.



Both pots side by side.



These pics were from last month, so will do an update on both of these pots soon.

Still waiting on flowers from this one.
