Hehe, yeah they are some of the forest of 40+ plants I'm currently babysitting. (I've already planted about 25 semps outside that I don't have to babysit thankfully).
It is pretty crazy that the ones named "creeping" don't really spread too much but others practically run around spreading at top speed.
Here are two Zebra Grass that just came in today.
Here are some semps that I've planted outside since these pictures were taken.
