I lucked into the first 5 magic plants. The last one I worked for about 2 full days of playing and finally got this evening. The aureus scandens. I just kept cross breeding all the scandens I could get and then breeding again. I finally got it tonight. I'll probably start all over again once I get the last 3 bugs. This time I'll know to keep some seeds that I'll need later in the game. It's been great fun.
