Last fall these two neoregelia 'Jeffery Block' plants bloomed and have remained pretty all summer but are starting to turn yellow now. I had not expected them to last this long. The plant on the right has sent up about a dozen pups but the plant on the left has not sent up any pups and is turning yellow quickly. Is this normal for this plant? A third plant on the back side is starting to blush now so I can enjoy it in my greenhouse this winter.

Sorry, my title didn't show up. It was question about 'Jeffery Block' pups.

Sammy, We're the three large plants you have growing offsets from one original plant?
It may not be too late to encourage the yellowing plant on the left to produce pups. Cut from the group with a sharp knife getting a bit of the underground roots. Pot it up on its own and it will probably produce pups.

Thanks for the information Scott. I will have plenty of pups from the one plant. I was just curious why there was so much difference. The three plants are probably connected. I don't have space for individual plants so I leave them in communal pots. When I bought the 'Jeffery Block' plant at a local nursery I didn't have any other Bromeliads and was not familiar with their growth. It was a pot full of plants and now I realize it must have been pups from one plant with the mother removed. I lot of the plants died due to my neglect leaving the three plants I have now.
