Ianto nodded as Sulu spoke, following along alongside him, although not really following what he had to say aloud very fast at all. He wasn't sure exactly what iceplant was, but it was alright that he didn't, he figured. Sulu would probably point out anything dangerous (because let's be honest here, Sulu and Jack were still that protective or him, even after all this time since everything had gone wrong).

"Anything that looks 'weird as all get out'," he said, repeating Sulu's words with a smile and a nod. "Alright. I think I can do that. I mean. It shouldn't be too hard, especially if it really is going to be just a matter of noticing plants that are fundamentally different from anything that I'm used to at the Hub in Owen's old hot house." Some of the plants from which had been saved from the blast. Others, the more finicky ones, weren't as lucky, Ianto was afraid, but it was no matter. They'd get other ones to fill in the missing spaces, and Sulu could even help figure out how to keep them alive, and then Ianto wouldn't feel half as bad about losing them in the first place.
