Roselia can have one of two Abilities: Natural Cure, which heals any status conditions that it may have become afflicted with; or Poison Point, an Ability that has a 30% chance of poisoning an opponent that uses an attack that requires physical contact against a Pokémon with this Ability, except for another Poison Type or a Steel Type, or a Pokémon that has the Immunity Ability.
A third Ability is available to Roselia from the Dream World, the Leaf Guard Ability. This Ability heals all stats problems when the weather is strong sunlight, either due to the Drought Ability or the move Sunny Day.
When it was introduced in Generation III Roselia could not evolve and did not have a pre-evolved form. Generation IV saw the introduction of a pre-evolved form, Budew, and an evolved form, Roserade. Budew can evolve into Roselia by becoming loyal to its trainer and leveling up (a Friendship Evolution) during the daytime. Roselia's evolved form, Roserade, can be obtained through the usage of a Shiny Stone.
Roselia is in the Egg Groups Fairy and Grass, and its Egg takes approximately 5,120 Steps to hatch; a Roselia will hatch unless the Roselia in the breeding pair is holding a Rose Incense. If this happens, a Budew will hatch instead, requiring the same number of Steps. It takes Roselia 1,059,860 Experience Points to reach Level 100.
Roselia takes on the appearance of a green plant that is holding two roses, one red and one blue. On its head are three thorns.
The leaf that covers a Roselia's midsection is slightly longer on the female than the male.
Roselia appears at Route 212, Route 221, Route 224, Route 225, Route 229, the Trophy Garden and the Great Marsh as a Daily Binocular Pokémon in Diamond, Pearl, and Platinum. In addition to those locations, Roselia appears at Routes 208, 209, and 210 in Platinum. Roselia appears at the Safari Zone's Marshland area after 25 Forest Objects have been placed in the area. Once this happens, Roselia will start to appear in this area 20 days later.
Roselia appears at Phobos Train, Endless Level 6 and Mr. Who's Den in Pokémon Trozei!.
In the first round of Mystery Dungeon games, Roselia is exclusive to the Red version, appearing at Uproar Forest 4F-7F. In Explorers of Time, Explorers of Darkness and Explorers of Sky, Roselia appears at Mystifying Forest B1-B13, Mystery Jungle B1-B29, and Midnight Forest (called Dark Night Forest in Explorers of Sky) B1-B24. Roselia also appears at Sky Summit PTC1-PTC4 1F-3F, PTC5-PTC8 1F-4F & PTC9 1F-5F in Explorers of Sky.
Roselia did not appear in the first Pokémon Ranger game, but made its debut in the series in Pokémon Ranger: Shadows of Almia at Vien Forest. Roselia also appears at the eastern part of Sophian Road on Sophian Island in Pokémon Ranger: Guardian Signs in the Present. Roselia does not appear in the past missions.
Roselia appears at Shimmering Lake Treetops 2-4 in Pokémon Rumble Blast.
Trading Card Game
Roselia appears in a total of seven sets. Roselia appears as a Common Card in the Diamond and Pearl, Stormfront, Supreme Victors and Unleashed sets. It is listed as an Uncommon Card in the EX Legend Maker and Secret Wonders sets. Roselia's lone listing as a Rare card came in its TCG debut appearance in the EX Dragon set.
The majority of Roselia's anime appearances occurred as one of the Pokémon that Drew used in various Pokémon Contests starting with the episode Now That's Flower Power! and continuing to The Unbeatable Lightness of Seeing!
Another trainer used a Roselia in the film Arceus and the Jewel of Life, the lone appearance for Roselia in the movies to date.
Roselia's Manga info is unknown at this time.
Roselia is in the PU tier of competitive battling. With a good defensive typing and high Special Defense thanks to Eviolite, Roselia makes for a solid support Pokémon. It can check Water, Grass, and Electric-type attackers in the tier very well. With access to Spikes, Roselia can provide entry hazard support for a team and has other great support moves in Sleep Powder and Synthesis. It can have a decently strong offensive presence due to a usable 100 Special Attack and solid STAB combination in Leaf Storm and Sludge Bomb. Roselia's biggest flaws are its lackluster physical bulk and reliance on Eviolite, which can be highly problematic when matched up against threats that it would normally beat but cannot due to them running a set that can beat Roselia, such as physical Floatzel and Knock Off Simisage.
Roselia is a viable option in the Neverused (NU) tier of competitive battling. With access to Spikes and Toxic Spikes, Roselia can be a highly useful Pokémon for a team to have and sets it apart from other defensive Grass-types like Vileplume. It has some very useful resistances to Water, Grass, Electric, and Fighting attacks, and its defenses can be bolstered quite a bit thanks to Eviolite. A very nice Special Attack stat allows for it to function pretty well as an offensive Spikes user as well and prevents it from being too easy to be set up bait. Outside of the standard specially defensive Spikes set, Roselia can run a Focus Sash lead set for hyper offense teams and surprise factor as well as an offensive Spikes set with Eviolite that can hit hard with Leaf Storm and Sludge Bomb. However, Roselia faces immense competition from Vileplume, which has much better physical defense and is not as susceptible to Knock Off, which allows for it to check much more Pokémon in the tier. Roselia also has competition as a Spikes user from the likes of Garbodor and Ferroseed, which have a different set of resistances that can allow for them to function better than Roselia.
Roselia is also usable in the Rarelyused (RU) tier of competitive battling. With access to Spikes and Eviolite boosted bulk, Roselia can function pretty well on stall and bulkier defensive balance teams. It can absorb Toxic Spikes and switch into Water and Grass-types very well due to its typing. Thanks to Natural Cure, it can switch into Scald burns and shrug them off once it switches, giving it even more utility as a Pokémon. Roselia's biggest flaw lies in its low base 45 Defense that is still susceptible to being taken advantage of even after the Eviolite boost. Its dependence on Eviolite is huge, and if removed, Roselia loses a lot of its utility in the process. It is also very much weak to Fire and Psychic-types, which are very common and will be able to take advantage of Roselia's presence. Defog users like Flygon and Togetic are very common so keeping entry hazards on the field can be difficult.
