One Phalaenopsis has decent aerial roots and a single mature leaf. The
centre looks dead, though.

Do they ever come back from this (growing centre damaged) or is it the
great compost heap in the sky?


Not normally once the growing centre is damaged.
Did water lay in the growing centre during the night?

No idea how it happened.

Just turned black and crunchy.

At some point in the indeterminate past.


If you'd overwatered it or wet the crown of the plant, I would have
expected it to be black and soft/slimy, rather than crispy. Could it be
underwatered/ too close to a radiator? Since you haven't much to lose,
why not tip it out of its pot and see if there's any living root and
crown worth saving?


Just wondering, do they bulk up with age and become multi crowned, if so
it must be from the sides not just from the crown.

In this case, with a Phalaenopsis, the plant is monopodial (having one
foot), so it adds leaves and grows upwards, but doesn't increase its
crown. Young plantlets (keikis) occasionally develop on old flowering
stems; just a tiny leaf at first, then aerial roots and more leaves.
When big enough to support itself, it can be removed and potted up.
