Well. At first, its kinda hard, but after about a month, you'll have most of the scientific names down pat... I personally would try to forget common names as there are mixups alot of the time...
I would stay away from North American Pitcher Plants (Sarracenia) if you are going to grow them indoors. Obvisously, you don't have too many yet, and I'm supposing you dont have light ballasta with plant bulbs hanging over a table now, do you? Ya, me neither... Hehehe... Sarrs are HARD for me to grow indoors without
proper plant lighting... Even a purpurea...
I would go with Drosera capensis:
or Nepenthes ventricosa:
They are both, as some people say, bombproof...
Choose one of these if you really want a 100% success rate... The only way you can fail is lack of enthusiasm... Really...
Ask for care instructions after you choose... Ifeel its easier that way...
That way you've dont your own exploring, and not only discovered the easy ones, but maybe some more vague ones... even if you dont get htose, you can still have learned, know what i mean?
