Barbara Bloom started out as meme but turned out to be so good. The idea is stacking Barbara with as much Elemental Mastery as you can, apply dendro, then use Barbara to trigger bloom reaction.
I guess we can say that Barbara is, late bloomer
When using Barbara in Bloom team, after applying dendro you will need use elemental skill then running around to melee distance of the enemy to get them wet, triggering bloom in the process.
Barbara can also using her Normal and Charged Attack albeit not so efficient when it comes to stamina consumption, so use it wisely.
Barbara have quite long skill cooldown: 32s. For this reason, it’s recommended to use Sacrificial Fragments that have passive to reset character skill cooldown.
A Thousand Floating Dreams is superior due to it’s bigger EM and passive value, but by choosing this you will have to spam Normal and Charged Attack while waiting her elemental skill cooldown.
Last one is 3 star Magic Guide, easy to get and max refine.
Best artifact for EM Barbara is 4 Flower of Paradise Lost with 4 set effect to increase damage for Bloom, Hyperbloom, and Burgeon elemental reaction.
|4 Flower of Paradise Lost||(2) Increases Elemental Mastery by 80.|
(4) The equipping character’s Bloom, Hyperbloom, and Burgeon reaction DMG are increased by 40%. Additionally, after the equipping character triggers Bloom, Hyperbloom, or Burgeon, they will gain another 25% bonus to the effect mentioned prior. Each stack of this lasts 10s. Max 4 stacks simultaneously. This effect can only be triggered once per second. The character who equips this can still trigger its effects when not on the field.
2nd best is 4 Gilded Dreams.

(4) Within 8s of triggering an Elemental Reaction, the character equipping this will obtain buffs based on the Elemental Type of the other party members. ATK is increased by 14% for each party member whose Elemental Type is the same as the equipping character, and Elemental Mastery is increased by 50 for every party member with a different Elemental Type. Each of the aforementioned buffs will count up to 3 characters. This effect can be triggered once every 8s. The character who equips this can still trigger its effects when not on the field.
And for last resort, you can go with combination of 2 artifact set with +80 EM Bonus

Team for Barbara Bloom?
Nilou Bloom Team
There’s no Bloom Team without Nilou. This team consisting of 2 Hydro with Nilou being one of them, and in this case we are using Barbara. Other character is 2 dendro character or 1 dendro and 1 EM anemo support.
Nilou Bloom team
Frozen Bloom, Fridge Bloom whatever you want to call it. Using 1 dendro, 1 cryo, 1 hydro enabler, and 1 utility (shield, healing,anemo 4vv). In this example, we are using Collei, Rosaria, Barbara (EM),and Sucrose.
Since cryo didn’t react with Dendro, this team allow us to utilize both frozen and bloom reaction. Sucrose or other EM swirl also help to gather enemy in one place so Barbara didn’t have to run too often.
