What will happen in nature if all plants can germinate seeds?

Such as the germination of seeds in all plants without exception or the germination of all seeds should not be categorically. Such a “invasion” of vegetation can be compared, perhaps, with a tsunami, but this “tsunami” is not water, but plant. Then there will be a lot of greenery in our world. Plants will overwhelm everything and everyone and it will be very difficult to fight it. People will only be busy fighting plants. Sprouted seeds will grow into plants and give seeds again, but in even larger quantities, because there will be more plants than usual. Vegetable greenery literally floods everything and everyone around.
