Haworthia picta 'Okubo'
The windows on these leaves are covered with lines and white spots that have blended together, You can see a hint of pink starting in the inner leaf of this one, which will get more pronounced with more light.
Haworthias can do well indoors if you have a bright window. They like morning sun but should not bake in hot afternoon sun. They are also extra sensitive to staying wet, they need very fast draining soil or their roots will rot.
Current plants offered are very established, grown in deep pots with robust roots. I left the old photos at the end.
