In Star Wars Jedi: Fallen Order, you can collect 10 total terrarium seeds from four of the planets. If you collect them all, plant them in Greez’s terrarium on the Mantis, and let them grow, you’ll earn the Green Thumb Achievement or Trophy.
Bogano terrarium seed locations
Kalpi seed // Subterranean Refuge
To grow a Kalpi, you need to find the seed in the Subterranean Refuge on Bogano. Go down to the big circular room — the one before the long hall where you get wall run. Drop into the water and walk around until you find a vine growing out of the water along the wall. Scan it to get the Kalpi seed.
Featherfern seed // Fractured Plain
To pick up the Featherfern, you’ll need to wait until you have the Jedi flip ability. Once you have it, Jedi flip over to the Fracture Plains on Bogano, and position yourself where you can see the three huts in the distance. Look for a single purple flower sitting on the edge of a cliff. Scan it to get the Featherfern seed.
Zeffo seed locations
Royal Fluzz seed // Weathered Monument
In the Weathered Monument on Zeffo — on your way to the Tomb of Eilram — you’ll find a small ramp that leads down to a locked chest. Next to the chest, you’ll find some pink flowers. Scan them to get the Royal Fluzz seed.
Gillypod seed // Windswept Ruins
In the Weathered Monument area on Zeffo, look for a patch of grass in the sand toward the middle structure. It’s on the roof of the ruins. Walk up to the grass patch and scan to get the Gillypod seed.
Dreamwort seed // Crash Site
For the Dreamwort, make your way to the Crash Site on Zeffo. To the right of the area, swim onto the center island. Scan the Dreamwort plant on the edge of the gray island near the water to get the Dreamwort seed.
Kashyyyk seed locations
Bonshyyyr seed // Imperial Refinery
In the Imperial Refinery on Kashyyyk, look for an enormous upturned tree with roots growing all around it. Scan the roots at the base of the tree to pick up the Bonshyyyr seed.
Milk Grass seed // Gloomroot Hollow
In Gloomroot Hollow on Kashyyyk, stay left instead of following the story path right. Look for a giant leaf sitting next to some bark and jagged rocks. Scan it to pick up the Milk Grass seed.
Mushbloom seed // Origin Tree
In the Origin Tree on Kashyyyk, you’ll come across a group of spiders after your mud slide away from the Ninth Sister. Look for a big mushroom in the back of the area, and scan the little mushrooms around it to get the Mushbloom seed.
Dathomir seed locations
Bleeding Gut seed // Swamp of Sacrifice
In the Swamp of Sacrifice on Dathomir, look for yellow rocks near some water. Look toward the cliff in front of you, and you’ll see a wall of red mushrooms. Scan this area to pick up the Bleeding Gut seed.
Mushling seed // Swamp of Sacrifice
In the Swamp of Sacrifice on Dathomir, in the wide, circular area, you’ll find some red flowers sticking out of the ground. Walk up to the plants and scan them to pick up the Mushling seed.
