Question
Hi, my S.flava has flowered, but my other sarracenia arent' flowering. So can I take the pollen from that flower and pollinate it.

Answer
Hi Jesus,

Yes!  You can use the pollen from the same plant to self-pollinate the flowers.  Within a couple of months, you'll know if the pollination was successful as the pod will swell up.  By early fall, you'll have seeds.

Good growing!
