@tinypixie - I think yours need more light which will bring up the purplish coloration. I also think the soil looks too heavy (looks like topsoil?) If you look at the others, they are planted in somewhat gravelly mix (about 10-15% smallest aquarium gravel, 10-15% builder's sand. OR something like the patio paver underlayment which is a mixture of sand and gravel). The downward curling of the leaves I think is symptom of the heavy soil and struggling root system.
The babies will form by the "thousands" when the plant is happy and healthy.
I haven't had one in a while but when I did, It was kept a group with other sun-loving container plants, and the babies basically RAINED down on them and rooted everywhere.
(... I'm not sure that technically those babies can be called "pups" -- I believe "pups" are ground-level offshoots. I think there's another word for them that I can't remember at the moment.... It's driving me crazy!
