Yes i realise that i have stated that most plants produce between 3 and 8 leaves. This is true for naturally grown Venus Flytraps. However there are nurseries out there that grow plants through tissue culture.

This basically means that the plant was born in a laboratory environment in a dish of nutrient-enriched agar, stuffed with hormones. The plant was then moved to a peat mix to be commercially sold through a nursery.

The Venus Flytrap will gradually slow, over the course of a few months, to a natural growth rate and will have the usual 3 to 8 leaves.

Why tissue cultured plants exhibit these strange growth spurts is unclear. Possibly because of the residual hormones still present in the plants cells even after transportation.
