Ok, so as expected that seedling didn't make it. Haiz. I thought it might be the transport that killed it, but the remaining seedlings at my uncle's house died too. Hmm... going to try growing from seeds myself. Bought a packet of seeds from NTUC and a 10-inch pot from Giant. But I'm worried that the pot might be too small, cos I read that sunflower roots can grow to 4 feet below the soil surface (!!). I don't know what species that author is referring to though...
