In the early game they are also extremely valuable because of their photosynthesis trait, which makes them non-taxing on food production.
Plantaurs are interesting "jack of all trades" and bring useful flexibility to the early game battles.
They have average HP and strength which is only slightly lower than a purebred Centaur, can quickly move across plains and charge the enemy while doing so.
This reduction in raw tanking and striking power is counterbalanced by their utilitarian set of skills, passive abilities and traits. Thanks to those a fully skilled out Plantaur is capable of acting as a minor healer (SpawnHealFlower, Rejuvenate, AbsorbWater on move) for himself and others, can whittle down high-value targets (Toxins), act as an engineer of sort, terraforming the map (GrassTrail, AbsorbWater on move), and seduce the enemy while dealing damage to him (Pheromones on attack).
Like purebred Centaurs they suffer from the "BadAnatomy" trait, making them susceptible to enemy seducers if left alone.
The LandMount ability gives them the option to carry smaller party members, reducing the time needed to traverse a land hex.
While Plantaurs virility is not as high as purebred Centaurs, it's still quite high. To make up for this they have high fertility, making them excellent at impregnating and being impregnated. Thanks to that they get high benefits from being Futas.
Their beauty is above average, making them a good candidate for a brothel spot, once their intercourse skills are high enough.
Plantaurs have extremely high semen and milk production, making them prime candidates for farm milking.
To fully exploit Plantaurs semen and milk production potentials, you need to first get the producer trait from Mya. This can be done by raising her relationship until she joins your party. Then you can either breed the trait to Plantaurs or copy it if you're playing Evolution.
Once you have the trait on a Plantaur or two, you can make them start milking each other. They will also produce eggs at the same time, from which you will get even better producers.
Their cum always taste really sweet and has aphrodisiac properties. You can often see others lining up to get a taste. So for this species, not being able to reach their cock is actually no a problem at all.
