It does not have any traits, and its ability creates a Seedling in its lane and in each lane adjacent to it when it is destroyed, unless those lanes are aquatic lanes or occupied by a non Team-Up plant.
It is based on the pomegranate (Punica granatum), a fruit-bearing deciduous shrub or small tree. It might also be based on the plant, Bombegranate in Plants vs. Zombies 2 with a similar name.
Its name is a portmanteau of "atomic bomb," referring to its bomb-like appearance, and "pomegranate," the real-life plant it is based on.
Its description references how atomic bombs work.

Strategies
With
Atomic Bombegranate has low stats for its cost; while it does hit fairly hard, its low health means that it is able to be easily destroyed. However, it is able to make up for it with its ability. The Seedlings it produces can turn into very powerful plants, including legendary cards such as Brainana, Three-Headed Chomper, and Bananasaurus Rex if you get lucky. But remember that this ability is luck-based in nature, so do not expect good results every time a Bombegrante is destroyed.
The Seedling on the left will be made on a lane where combat has already occurred, allowing it nearly guaranteed survival until the next turn when it will transform. The Seedling on the right, however, will have a harder time surviving the Fight! phase, so you may want to play a Team-Up plant there first. If necessary, the Seedling on the right can function as a shield to block an attack, and the Seedling's two health may allow it to survive if there happens to be a weak Zombie in that lane.
Atomic Bombegranate's downside is that unless you have Team-Up plants, it requires three empty lanes to be fully functional, which means you will either have to settle for less Seedlings or risk leaving two lanes open to zombie attacks. This naturally makes it tougher to use it with Muscle Sprout and Astro-Shroom too, as their ability activating thrice may not compensate for the sacrifice you made to do so.
Against
While Atomic Bombegranate itself is easy to destroy, as there will be many options available by turn 5, doing so will not end the problem completely, as the Seedling it makes have the chance to turn into dangerous plants.
Since the Seedlings will transform right after the Fight! phase on the turn Atomic Bombegranate is destroyed, you only have the Fight! phase that turn to destroy the Seedlings before they transform. As you will most likely be unable to destroy the Seedling on the left due to the combat order, you should expect to face at least one surprise the next turn.
This outcome is avoidable if you can destroy Atomic Bombegranate (and possibly the Seedlings too) during the Zombie Tricks phase, but this is only possible if you are a Crazy, Brainy, or Beastly hero, as only these classes have access to instant-kills and damaging cards (including Total Eclipse).
Another way to deal with the Seedlings is to move the Atomic Bombegrante to the leftmost or the lane right next to the aquatic lane such that it will only make at most two Seedlings upon destruction or Bouncing this plant to prevent its ability from activating. Since your opponent may have left many lanes open for the future Seedlings, doing so can also potentially deal lots of damage to their hero.
Assuming they survive, Frenzy zombies are also able to destroy both the Atomic Bombegrante and the Seedling it produces. Frenzy cards that give rewards upon destroying a plant, such as Ancient Vimpire or Interstellar Bounty Hunter will trigger their ability twice, and Supernova Gargantuar in particular deals with both the Atomic Bombegrante and its offspring very well.

Trivia
Prior to the Colossal Fossils update, it was one of the two non-legendary cards to have the legendary shine effect attached to them when they were played, the other one being Octo-Pet.
It was also the third card in the game to display the aura again, in this case, when attacking and activating its ability. The first and second were Soul Patch and Wannabe Hero (when attacking).
In promotional advertisements featuring it, it appears to have a fuse. The only other time this fuse is present is when it activates its ability and when it is played.
