Well, my windelov java fern puts out new leaves like crazy, one leaf every few days. And my narrow leaf java is slower, but still at least one new leaf per week or 2 at most. So I guess it depends on your definition of slow, but I'm pretty happy with their growth rate when you factor in their ease of growth. I literally have not fertilized the tank with the windelov in it ever and it's growing like crazy. I got it about a month and a half ago with about 10-15 leaves on it and i'm at about 25-30 now, with 2 baby plantlets growing off the tips of some of the leaves.
