None of those plants will produce a Citrus Reptans. Seriously, since you have so much time invested in the game, the best approach is to buy the common seeds from the store each day until you get a Citrus Reptans. You could always start a second game in another player slot and use that to experiment. If you don't get the plants you want right off, you can start over until you do. Then, at least, you'll have experience making the plants you need. \:\)

None of the Magic Plants require Tier 4 plants, which are very difficult to get, anyway, and are intended as a late-game (optional) quest.
