My steroid champion was Chlorophytum comosum, the lowly Spider plant. In late May I ordered a collection off evil bay, I received unrooted pups and started them outdoors in 4" pots. Today they are in 8" baskets, the largest is 18-20" and I had my first flower last week.
Runner up is my Davallia, Rabbit's foot fern, I bought 4 var. in late May and two are filling 8" baskets already. I let one get to dry and lost all foliage but it's coming back great My D. Canarionsis came as a pair of roots, it took a while to get that first shoot but it's growing and it's going to be much larger than any other. Very large stems and upright growth. First leaf when up 20+ inches.
