I actually planted this a couple of months ago. There were two of them that were of this variety - M. Tomoc. Both were two foot long sword pups. The other is growing really good, but this one just kept getting black and mushy until it was just 6" tall and 3/4' diameter of black sheath, although I was spraying it with fungicide twice a week.
4 weeks ago, I saw what I thought was a weed, but turned out to be a new slender pup. The following week, this was followed by a green slit in the blackened original sheath that turned out to be the original plant pushing out some growth. Another week after that, there was another pup growing. This was taken over a week ago. The newest pup has actually leafed out some.
Original plant is in the middle back, first pup is the one in the back on the right, newest pup is in the front.
