I wish biology teachers had Plant Tycoon based on real plants to help students learn about genetics and trait inheritance. The game is all about breeding and cross-pollinating plants to create expensive and rare plants as well as the six magic plants. This one is more an interactive experience in pumping up your green thumb than it is a game.
The game looks familiar to Virtual Villagers players because it comes from the same developers, Last Day of Work (yet they keep working!), and these plants hail from the exotic island of Isola. Virtual Villagers takes place on Isola and the graphics style and dialog boxes are the same. You’ll also recognize many customer faces in the nursery as they look like the people of Isola wearing modern clothes.
Also like its ancestors, Plant Tycoon is a real-time game where the plants continue growing even after closing the game. Players have the option to pause time and change the speed of time to slow, normal or fast. So if you’re off to bed or work for the day, either pause the game or switch to slow mode to ensure your plants don’t check out.
The game isn’t without its pests — figuratively and literally. The literal part involves catching butterflies and insects with a net. This is an optional game within the game. Virtual Villagers fans will recall the adventures they had trying to catch every rock, bug, and shell to complete the collection.
The nursery where you sell the plants is the biggest pest — figuratively. If you exit the nursery to change a price or anything else and go back in, the customers start over. If you had hordes of people inside the nursery, they’ll be gone and you’ll have to sit and wait for them to show up again. I wish there was a way to change prices while in the nursery and that the nursery would keep running even if I’m not in that screen. When it comes time to sell the plants to make room for new ones, I open the nursery and go do something else to past time.
Shop at the store for supplies, which includes three levels of soil, water, clippers, nets, and seed collection box. You must buy a level one item before a level two, a level two item before level three. The level of supplies affects your ability to grow exotic and rare plants as well as in catching the little buggers.
Oh, how this game can go on for days and weeks! I tried to keep track of the plants and seeds on paper. That didn’t work. It was too complicated since there were too many similar seeds and plants. Then I tried using the amazing spreadsheet that contains the breeding charts, but there were too many combinations and I couldn’t make up my mind which to do.
If I had more time on my hands, I’d study these guides to better understand the breeding formula. It makes sense when I break down the chart to a small 5×5 grid, but to apply that to every single combination with over 500 plant possibilities… forget it! That’s what makes this game unique (other than Fish Tycoon from the same developer) is that it makes you think. You can only store so many seeds that it’s tough to decide which to keep as it takes no time to fill up the seed box.
For busy and impatient folks, Last Day of Work posted great guides, charts, and spoilers in its forum. Clicking the link takes you to the forum list where no spoilers appear. You can see the post titles so you can decide what to look at. Be prepared to have patience when starting the game. It takes time to grow plants and build up the funds for bigger purchases.
I love creating new plants and seeing what would show up after cross-pollinating two plants. It would be nice to have a feature that keeps track of all the plants I’ve made. I tried doing that myself, but it was a monstrous task. The game does have stats indicating the number of species you discover, plants sold, bugs caught along with your rank for each.
I also enjoy clipping the dead parts of the plants and seeing the plant change to reflect the clipping. Those with brown thumbs like mine can play Plant Tycoon without worrying about killing plants. Gregor Mendel, “father of modern genetics,” would be proud.

what is the best plant send mix to ecwisthebest@googlemail.co.uk
thank you
What do the bubbles above the villagers heads mean? Is there a place where I can go and look up all the symbols that show up?
Actually, Brother Mendel would be hopelessly confused by the plants of Isola and their weird genetics. They seem to follow the principle of “blending inheritance” which was a theory of genetics popular in the Victorian era, but was actually refuted by Mendel’s experiments.
Example from Isola:
If I cross a fourpetal plant with a jalapa-flowered plant, I get hybrid seeds that grow into plants with fragrant flowers.
Genetic interpretation: Maybe fourpetal and jalapa are co-dominant and therefore their combination causes the fragrant phenotype, which is different from the parents. So let’s call the gene locus for flower types “A” and assume that fourpetal is caused by allele A1 while jalapa is caused by allele A2. Every plant has two alleles of the gene (one from the mother plant, one from the father plant) and A1A1 is a fourpetal plant, A2A2 is a jalapa plant, and interestingly A1A2 is a fragrant plant (due to co-dominance of the two alleles).
The cross is:
A1A1 x A2A2
All F1 hybrids are A1A2 and all are fragrant. This still makes sense.
The problem is the F2 generation. When I take the fragrant F1 plants and self-pollinate them, Mendel’s law of segregation predicts that I should get:
F1: A1A2 x A1A2 =
F2: 0.25% A1A1 + 0.5% A1A2 + 0.25% A2A2
So there should be fourpetal, fragrant, and jalapa flowers in a 1:2:1 ratio.
But all I get on Isola are fragrant flowers in the F2 generation. How?
I assume what happens on Isola is the following:
Parents: A1A1 x A2A2
Hybrids (F1, F2,…): A3A3
The two alleles of the parents blend together to form something new (A1+A2=A3) that wasn’t there before and there is no way to recover the original alleles from the hybrid plant.
This is completely contradictory to what Mendel found. He saw that the characteristics of the parents in a cross will segregate in the F2 generation. This doesn’t happen on Isola at all. I’ve never seen anything segregating in these plants. (And as a genetics teacher, I was a little disappointed by that.) They just blend together to form new species and all the seeds you get from that new plant then grow into more of the same new species. Back-crosses (e.g. A3xA1 or A3xA2) don’t work either. They give you yet new species of plants again (A4, A5 etc).
So Isola appears to be a fantasy world based on a Victorian era idea of genetics where the parents’ genes blend together to form new genes, and where Mendel’s rules do not apply. It’s still a fun puzzle game, but it has nothing to do with modern genetics at all and won’t teach you anything useful for biology class in that regard. In the real world, traits might blend, but alleles never do and the evidence for that is in the F2 generation producing parental phenotypes again. The genetics of Isola don’t work that way.
