Liverworts

[stevebradford]

From time to time I get liverworts popping up in my carnivourous plant pots. I usually just let them grow, do their thing as they never take over and they look interesting. This is the first time I seen one produce little Gemmae wading pools.

I never knew those were gemmae. I thought they made spores.

Both!

I believe they release spores from these openings.

I believe they release spores from these openings.

No, those are air pores that this moss uses for breathing. Marchantia polymorpha releases spores from little starl-like/umbrella strucures (gametophores). Male ones have a small disc on top with spores underneath.
This is one of the few mosses I prefer to remove from pots. Those splash cups are too efficient.

star-like/umbrella spore strucures!

Cool.

They do have a prehistoric kind of look to them but if left unchecked, very hard to get rid of. It does embed itself in the media reaching a couple inches down when it starts to colonize.

Found this Marchantia when weeding my Senpervivum planters. Thought might as well try and grow it instead of just tossing it in the compost. Kept in a northern windowsill in nutrient rich peat+perlite, watered when the pot feels pretty light.

I have those lacy-like liverworts that can go crazy. They aren't obviously herbicidal.

I love those little baby palm tree looking guys! I love bringing them home in plants I get from commercial growers, but I haven't been able to keep them alive at home yet.... Then again, I've only tried keeping them outside (north facing, shaded yard). Next season I'm bringing some inside!!
