i'm looking for a temperate drosera, or Utricularia, the one on soil not the aquatic one(i've never tried these). or small square pot(s)

i have like 7 flower stalk coming up right now... just wondering if there's any way to save the pollen until the other one opens, or how long until the flower closes. i have 2 that's definitely like 2 days apart, and the rest will be like 3-6 days apart

ps. i'm pretty sure its a typical.
