A lot of the pots I've seen it in are much deeper, so it takes a much longer times to reach down to that point (and half the time if they get that far they just break the pot instead because the rhizome got too thick for the pot to hold). The growth point pointing straight down is a little weirder, but a bit easier to achieve with the prophylls present rather than the leaves that, as the other points show, twist around and grow upward fairly quickly.
