How many traps do they normally grow
Venus flytraps typically grow around about 4-15 leaves.
Dozens of traps
If your plant is growing 16+ traps and some of them are reasonably sized (1 cm across), then it is possible that you may have more than one plant growing in your pot. This isn’t a big deal and don’t panic. Your extra plants will usually happily coincide in the same pot no problem at all. If they are already in a very small pot (4 x 7 cm) then you may need to repot at some stage to give them room to grow.
If your plant is brand new, it is possible that it is fresh out of tissue culture. Many plants sold in shops are grown in labs with all sorts of exotic chemicals, nutrients and hormones. This process often leaves the plant in a rapidly growing state and they may not get over this for a few months after purchase. They should eventually slow down however, many of the traps will die and the remaining few will hopefully (fingers crossed) grow nice and big.
