Introduction
Backwardsn’s Optimized ACNH Hybrid Recipes. Yet another doc of hybrid recipes, with a twist: each recipe was discovered by a recipe optimizer program. Possible due to Paleh’s guide on Mendelian genetics in this game https://bit.ly/348DAmJ and dataminers finding the flower flags https://bit.ly/3b7MB25 and J_MASTER’s studies on dense block shapes. Also the general ACNH discord. Code is on gitlab (click)

Optimal Layouts
TIP: Use dirt, sand, dark dirt, etc. pathing to mark the squares that contain parents or those where offspring should spawn. That way, if you ignore your garden for multiple days and it rains you can still keep track of which are the original parents and what are offspring. Flowers will reproduce onto any square that you can shovel, except the beach.
Cloning a single color
To make more of a single color, place individual flowers separated by a gap on all sides (diagonals not touching.) This produces genetically identical clones only: no crossbreeding occurs in this layout (click here for an explanation). You can weave multiple species to make better use of the space, as in the second and third examples below.
Note: If you are trying to clone Blue or Black roses or Purple Hyacinths, Pansies, Tulips or Windflowers and you are limited by space, not flowers it’s more space efficient to do dense blocks because for these flowers all crossbreeds have the same color see Identical Parents.
PROS: Produces genetically identical clones, works with just a few flowers.
CONS: Not space efficient unless you weave multiple species
________________
Identical parents
If both parents have the same color and came from the same recipe step place the parents in dense block shapes. This section of the guide by J_MASTER.
PROS: Can be arbitrarily dense (70+%) and has high yield, negligible self cloning
CONS: Only works if parents are the same color and species.

Different parents, desired offspring same color as parent
If both parents are different, use independent pairs. This layout gives you the opportunity to cross two different species simultaneously while ensuring all offspring are true crossbreeds.
PROS: Fairly dense (66%) and has high yield, no self cloning
CONS: Requires a second species
This intertwined diamonds layout works equally well, and is quite fetching:
It might surprise you that this layout also prevents self clones. This is because each diamond every flower has exactly 2 pairs, and there’s no way to end up in a self-clone situation. Neat!
________________
Another good option is 5x1s, this layout uses only a single species! It is slightly less dense than independent pairs in a block with two species, but this layout can line paths in an elegant way. The flower on both ends can self-clone, the other flower cannot. So, in order to ensure you get a pure yield of the desired color, put the parent with the same color as the desired offspring in positions 2 and 4, and not in positions 1, 3, or 5.
PROS: High yield per flower, lines paths, flower in position 2 and 4 doesn’t self-clone.
CONS: Not as dense as independent pairs.
So, there are lots of options for this case - which is best? In this graph, higher is better.

Parents, desired offspring different colors
When the parents and desired offspring are all different colors, try the alternating snake:
Or alternating rows/columns:
PROS: Both give high offspring per flower. Snake line paths but is slightly less dense than alternating rows/columns for filling block areas. Denser than 5x1s.
CONS: Not as dense as independent pairs. Many self clones.
Another layout that would work for this case is X-shapes in a grid. This layout is not recommended because the overall number of desired crosses per area is low, due to a high fraction of self clones. This layout can be adapted to any size, just make sure that no two flowers of the same parent type are touching (even diagonally.) Examples:

How do I get more offspring?
Usually, flowers that are watered by you will give ~1 offspring for every 10 each day. There is no limit on how many offspring you can get each day [1]. If the flowers are watered by visitors from another island, it increases the offspring you get per day, and this stacks for up to 5 distinct visitors. The game counts how many times you’ve watered a flower and adds 5% to reproduction rates per day since the flower last reproduced starting after the 3rd such day. This means that the game prevents you from having very bad luck. It also means you should definitely water planted flowers at every step as they’re growing, because the hidden counter increases and will give you higher rates when the flower matures [5]. Here’s a table of all of this:
Base reproduction rate
(per flower)
With “bad luck” counter (per pair, simulated, 10d)
Multiplier over self-watered
Self watered
0.05
0.171
N/A
1 visitor watered
0.25
0.451
2.63x
2 visitors watered
0.35
0.588
3.43x
3 visitors watered
0.50
0.740
4.33x
4 visitors watered
0.65
0.874
5.11x
5+ visitors watered
0.8
0.960
5.61x
At 0, 1, 2, 3, 4, and 5 visitors, a flower without any neighbors will self-clone at a rate of 12%, 28%, 37%, 51%, 65% and 80% per day, respectively (simulated, 10d).
UPDATE 2020-04-21: Lillies of the valley have no effect on flower reproduction [6].”
