The Party Rose cannot be unlocked through normal methods, which are sticker packs (excluding the Infinity Packs). Instead, the player must open Infinite Infinity Chests in Infinity Time to get her stickers, and that means he or she has to collect at least 25,000 Time Shards in that mode to have a chance at unlocking her.
There's never a dull moment when Party Rose comes around. Her Party Thistle fireworks routinely keep the Plant forces partying well past their bedtimes.

Party Time!
Party Time! is the variant ability for Party Rose. By getting Vanquishes, the bar for Party Time! fills up. When the meter is filled up, Party Time! activates (giving Party Rose a temporary speed and damage boost until the bar either depletes or until she is vanquished). If Party Rose is Vanquished before the meter is filled, the meter will reset.

Strategies
With
Party Rose benefits greatly from being a Party Variant, as she deals only 1 less damage than her stock counterpart, but has 2 less ammo. Considering how strong her stock counterpart already is, she can be one of the strongest Plants in the game. Party Rose appreciates the damage bonus and the speed bonus provided by "Party Time!" as it will be very easy to achieve this mode, whether against the AI or against players, since its damage output is strong until then. A strategy to achieve the Party Time is vanquishing one zombie at a time or hide if low on health. Use spells when in danger. Using Arcane Enigma during "Party Time!" stops and resets the meter. Due to Party Rose's low ammo capacity, it can be quite difficult for some players to vanquish high health Zombies (All-Star, Super Brainz). Try to aim at weaker Zombies like the Imp and Scientist.
Against
Zombies should be very cautious around the Party Rose, as her homing attacks make it very easy for her to vanquish you. She also has a stun, an Escape, and a debuff if any Zombie tries to get close. Try to avoid contact with her if she is in "Party Time!", as the buffs she gets from the ability make it hard to take her out. She is rare in multiplayer, but as always, avoid her spells and you will have less of an issue dealing with her. Ice variants are very effective counters to Party Rose due to the fact that projectiles fired by them can slow and eventually freeze her in place (making it easier for you to finish her off).
Just like the normal Rose, her sound effect when she shot continuously was changed from an ascending tone to a descending tone in the Trials of Gnomus DLC.
