I have a question for the pro's: My first game I got the Fabled Lemonbush first and it was priced at 227.00. I had no problems planting it in regular soil, then on up to Isola soil.
Now my second game, I found it first again, but it came up priced 304.00 and it won't thrive in the blue organic soil either. I don't know what has changed. In the first game I used this plant to make my money to buy the organic then the Isola, now it doesn't work. Any ideas??? Ame thing happened with my 2nd plant also.

There is a random element to certain aspects of the game, so that no two games will ever be exactly the same. The Fabled Lemonbush is a Tier 2 plant with a Tier 3 flower, so it technically cannot "thrive" in the Bio-organic soil and will require Soil from Isola to truly do well. How hardy a given plant will be in soil that is not adequate for its growth may vary from game to game.

Got ya! Thanks for responding!

does it vary from plant to plant?

for example, if i have a fabled lemonbush that i discovered from breeding while in lvl 2 soil and it does not survive, and then later in the game i discover it again from a different parent pairing, will i have a chance for the second fabled lemonbush to survive?

I don't think it matters what set of parents produced the seed, however other environmental factors may exist on how well a plant survives, including use of the various formulas and how many dead plants can be trimmed away.
