Crinum asiaticum - grow & care (herbaceous geophyte bulb) 

I have a 16 Years indoor Asiaticum Crinum and and 3 Years Old Pink Crinum i grow it outdoor in my garden and already blooming I don't know it's Crinum or not but 3 years ago i bought it's bulb in the name of Crinum ❤️

I have a question, can they grow in water? my mom just gave me one and I'm trying to think what to do with it cause she put it in water and now gave it to me saying it doesn't grow.
