Below is a screenshot of a cross that produces a Thavnairian Onion seed (click to enlarge).

Planting a Broombush seed next to a Curiel Root seed (or vice-versa) will yield a Thavnairian Onion seed when you harvest either the Broombush or the Curiel Root. The two arrows indicate that it doesn't matter which seed is planted or harvested first to obtain the desired crossed seed. If a seed has a loop (meaning you can use a seed to obtain more of the same seed) the cross will be highlighted in yellow.

As of Patch 2.3 every cross can produce different seeds if the crossbreed was successful. In the example shown above the Alternate Cross is Shroud Tea which means there is a chance you will obtain a Shroud Tea seed instead of a Thavnairian Onion seed upon harvest.

Definitions of each column:

Parent A: This is one of the seeds required to obtain a specified cross. It should be planted next to Parent B.

Parent B: This is the second seed required to obtain a specified cross. It should be planted next to Parent A.

Grow Time: This is how long (in Earth Days) the seed will take to grow from seed to harvest. The grow times do not take into account for fertilizing. They represent the actual grow time without fertilizing. It is possible to reduce the grow time by using Fertilizer, however, there is a limit to how much you can use before it becomes ineffective. Please see the Fertilizer Analysis page for an in-depth discussion on the effects of fertilizer on plants.

Alternate Cross: Many crosses have the potential to produce two different types of seeds. If a cross is known to produce another seed the alternate crossed seed will be shown here with a link to the respective seed.

Efficiency: This is measure of how efficient a cross is. This is explained in detail below.

Wilt Time *: The time it takes for a plant to turn purple (in Earth Hours) without tending. All plants wither (die) 24 hours after turning purple without tending.

Crop Yield *: The number of crops yielded based on the soil type used. Order is:

G1-3 La Noscean & Thanalan / G1 Shroud / G2 Shroud / G3 Shroud.

Seed Yield *: The number of seeds yielded based on the soil type used. Order is:

G1-3 La Noscean & Thanalan / G1 Shroud / G2 Shroud / G3 Shroud.

* found on seed details page


The Efficiency System is a scale that determines the cheapest, quickest and most reliable way to obtain a cross for a specified seed. Each cross takes into account the Availability and Cost of each seed as well as the Grow Time of each seed and whether or not it can produce alternate seeds.

Each cross has a colored icon and shape next to it which gives a general idea of the efficiency of each cross. The cost of each seed is an estimated average across all servers, however, this will of course lead to some inaccuracies in the output so be sure to check current Market Board prices before committing.

The crossbreed table will automatically sort by Efficiency with the most efficient crosses being listed at the top and least efficient at the bottom.

An explanation of the icons and weight categories is listed below:

Icon Explanation

Most efficient; use any (preferably higher in the list)

Can become costly and/or time consuming; use if no green available

Very expensive & time consuming; avoid at all costs

Abundant (Tier 1 Seeds & Grade 1 & 2 Nodes)
Normal (Tier 2 Seeds & Grade 3 Nodes)
Rare (Tier 3 Seeds)

Cheap (< 10,000 gil)
Average (Between 10,000 & 40,000 gil)
Expensive (> 40,000 gil)

Grow Time
Takes the average grow time between the seeds

Alternate Crosses
It is preferable to use a cross that does not produce alternate seeds. So if a cross only produces one seed this will raise the efficiency of the cross.
