What colour were the flowers when it was blooming? If yellow, and it grew from a rosette of leaves clustered on the ground, it could be skeleton weed, which is a reportable weed. If so, it would be best to check with the Ag Dept as if it gets hold it can be a big problem.

that's not a biting of anything. it's some kind of damage done to the leaf. It could have been folded or crushed at some point. maybe when it was repotted several leaves got crushed. So not problem there. the rest of the leaf is a good colour of green. Its not lacking sunlight for sure. Now if you placed it outdoors in direct sunlight it would have caused sunburns and damaged the plant. -- an error I made myself when I transplanted here in Canada. I came from the tropics where these plants are plentiful. These are under canopy plants and so they enjoy indirect sunlight -which is the reason they have such large leaves because that's needed for all the sunlight they can get. They are climbers too as they tent to grow up jungle trees to capture that sunlight. But they always stay within the shade. Yep, they can grow upwards of 20 feet. I've seen taller growths in the rainforest. However you do need to consider root space. if it's cramp then it can no longer sustain taller growths. you can always keep it short. Anyway.. you get the point. No direct sunlight. And lots of humidity.

Ledebouria socialis--violet squill. I have a silver squill that looks just like yours but mine has tiny white flowers. This plant spreads fast and is SO easy to care for. Leona
