I have a question about the Jack in the Pulpit in the attached photo. Until this year it was tall and the star in the garden. From a photo taken last year it was at full height by the middle of August but this year it doesn't look like that is going to happen. It seems to add a new stem each year or so. I am not sure if they are all connected or seedlings. I am not sure if they are crowding each other and so stunting the growth. What should I do and when?
