With the coming graphical update now seems like a good time to revive a discussion that
lost steam years ago, about dwarven vegetation.
Something that DF is currently almost entirely lacking is flowers, and with graphics they seem like a perfect addition. Small unobtrusive wildflowers (and underground mushrooms) can spice up the currently monotone grass fields in a visually pleasing way, and when cultivated in a garden (later) they could become larger and more vibrant with cultivation. Dwarves with the right personality traits (artwork, tranquility, harmony, leisure time, peace, and especially nature) would be able to spend time admiring them and gain a positive thought, and perhaps satisfy a need while they're at it, all while at a higher risk of being stung by a bee.
In order to plant your flowers, mushrooms and even trees, of course you'd need a new option for the Building menu: [P]. From here you could choose to plant a seed, either gathered by an herbalist or traded for, and as long as it's an appropriate tile (same as a farm plot) a dwarf with the grower labour can plant it in the ground. If you don't want to deal with dirt and mud indoors, a small pot (distinct from a large pot but made of any of the same materials) can be placed first to allow the seed to grow. Of course you can only pot a small plant, not a whole tree!
Of course, what's the point of putting down plants if nobody's going out of their way to admire them? That's what the new Garden location is for. Assigned the same way as any other location, gardens (or orchards if they're filled with planted trees) require containers to put seeds and fertilizer in, and can have gardeners assigned as an occupation. Dwarves will hang out in gardens when they want to fulfill their needs to admire or spend time among nature, without having to risk wandering out into the wilderness. Once there they may decide to spend time in solitude or they may occasionally throw a garden party with music and dancing. They will generally take care not to trample on any of the planted vegetation, though be careful of any dwarves with pets, because their pets will have no such compunctions! On the other hand, cats will keep the vermin population down too, as bees aren't the only vermin that love to hang out in your gardens.
That's all I've got on this topic for now. Thanks for reading!
