I'm assuming that you can, but unlike the premium gachas, there's no button that lets us see the contents, so I was wondering what 4-stars other people have gotten from the machine. 4-stars I've seen from the free machine so far:

4 - Yulan
3 - Cepha Lanthera
2 - St. Paulia
2 - Cyani Cornflower
1 - Violetta Tulip
1 - Snowflake
1 - Dandelion

I'm mostly bothered that I haven't gotten any pierce units yet, but it's probably just RNG (not to mention there are fewer pierce 4-stars). Also, has anyone gotten the new 4-star in the free gacha? I'm not sure if she's in the free gacha if she hasn't even been added to normal premium gacha yet.

2 snowflakes....not so unique now are you?

Yes, you can get 4* units from seed (free) gacha. The only ones I've yet to get are Hibiscus and Snowflake.
As for Lilac (new 4*), no idea if she's already in the seed gacha. If she's not, she'll be added once that limited gacha thing for her is over (probably?).
And yes, I had the same issue in getting pierce units. I already have Cary Ophyllus and Marigold evolved when I pulled Canola from the seed gacha.

I think I got Saffron Tulip, Casablanca, Saint Paulia, Canola and Hinoki Cypress, 1x of each. But 4 Yulans? gimme

I got the following *4 incl 1 from a code
1) 1x Bianca Tulip
2) 1x VioletteTulip (From code?)
3) 2x Sweetea
4) 4x Dandulion
5) 1x Di Yu
6) 2x Hioki Cupress
7) 4x St. Paulia
7) 2x Canola
8) 1x Hibiscus

Side note...go get and use the code if you haven't already. There's a list of them right here in this site's wiki:

Alright thanks for the confirmations. I guess I'll save up normal gacha seeds and hope they add the new 4-star to the free gacha after the event is over.
