Trying to finagle a way to make a more considered version of this guide... it seems some of the information I got from the Sims Wiki was... inaccurate? Or at the very least outdated.

Hmmm.

EDIT:

Current analysis suggests that, in the base game, every possible 'special' grafting combination can be held within a minimum space of:

two 2x2 garden planters, which each hold four small plants or one tree (eight plants)
three 1x1 garden pots, which each hold one small plant or tree (one plant, two trees)
total number of squares occupied: 11

With the vertical planters (which are very space efficient, but cannot hold snapdragons, lilies, or orchids) from Eco Lifestyle:

four 1x1 vertical planters, which each hold two small plants (seven plants + one free slot)
four 1x1 garden pots (two plants, two trees)
total number of squares occupied: 8

The wiki claims that Dragon Fruit can't be held in vertical planters, but this seems to be...wrong?

Further notes.

In my original post, I claimed that growth rate influences how often product is generated. This is untrue - it was true in old builds on the game, but in the modern version of the game all plants produce product at 5 am every morning, regardless of growth rate. It may still have some influence on how long a plant takes to mature, though.

In an outdoor garden, with Seasons installed, the optimal grafts (listing the "base" plant first, and the "donating" plant second) for max production days are:

Snapdragon (Spring/Fall) + Strawberry (Spring) = Dragon Fruit
Snapdragon (Spring/Fall) + Dragon Fruit (Fall) = Cow Berry
Snapdragon (Spring/Fall) + Lily (Summer) = Orchid
Orchid (Spring/Winter) + Pomegranate (Winter) = Death Flower
Bluebells (Spring/Summer) + Strawberry (Spring) = Grapes
Rose (Spring/Fall) + Grapes (Fall) = Bonsai Buds
Sage (All Seasons) + Basil (Summer, Fall) = Parsley
Chrysanthemum (Summer/Fall) + Tulip (Spring) = Bird of Paradise
Lemon (All Seasons) + Pear (Fall/Winter) = Plantain

Additional notes:

For an indoor garden with vertical planters, the first two snapdragon recipes should be reversed.
Daisies (Spring) and Strawberries (Spring) are basically interchangeable in their grafting recipe.
Apples (Fall) and Cherries (Summer) are both active for one season each, though Cherries have a slower growth rate.

Finally, the following base game plants are neither components nor products of any splicing "recipes":
