I have just recently self-pollinated Paperwhite narcissus, it was not as hard as i thought, but it will take some time to actually see what it is you are looking for. What i did was i grew 4 bulb plants (paperwhite narcissus) it did not take that long for them to bloom, 2 of them actually bloomed on Christmas. but the trick i do; i read in a book,
is pick two plants either of the same flower or of a different plant. Clip the flower off and then clip the petals off and make sure that you do not knock off the anther(pollin). use the anthers of the flower that you just clipped off, and rub it on the stigma of the other flower/plant that you are pollinating. make sure you get abunch on it just incase. next all you have to do is repeat to as many other flowers you want. Then just let them grow, keep watering them and plenty of sun like you would do normally. Finally just wait for the plants to die and you should if all went well see seed pods becoming larger. Then you know that you have done a job well done. That is as far as i am with mine so i have 3-4 more weeks before my seeds are done maturing, but i will post you again if you would like me to answer anymore of your questions.

I would recommend starting with a bulb flower, they are easy to grow. I would suggest paperwhite narcissus, right now rather than roses because of your money situation, but i can't remember if they will grow this time of year or not? You may have to ask someone else. Also i am growing these inside.

Sincerely,
