Solar Radish

The Solar Radish is a PvZ2 plant that collects sun for the player in a 4 tile radius. They will charge up for every sun collected until 500, at which point they become fully charged. Once charged, they cannot collect any more sun but can be tapped to unleash a powerful sun beam similar to the Magnifying Grass' plant food effect. After this, they will revert back to their initial state.

Suburban Almanac Entry
As a recreational beach-goer, Solar Radish enjoys soaking in the hot rays on a nice summer day. Of course, he likes to give a little something back to his community too.

Plant Food
Focuses a large, destructive beam of sunlight that instantly incinerates the zombies in its lane, doing insta-kill damage.

Strategies
The Solar Radish is best utilised for strategies requiring high sun-production, as it can aid the player in collecting sun and will provide additional offensive support. Solar Radishes are also ideal for situations where lots of small sun is created, such as with the Sun Bean or Helioscope, as they make it significantly easier for players to collect the dropped sun. Solar Radishes are also ideal for situations with sun-stealing zombies, such as the Ra Zombie and Turquoise Skull Zombie.

Planting just one Solar Radish is limited as it will not collect sun for the player when charged, forcing them to use the attack or collect the sun manually for a period. Planting two or three Solar Radishes can allow one or more Solar Radishes to be charged while still allowing sun to still be collected by the others. Avoid planting too many of these plants as they're expensive and this could serve to be pointless. However, larger numbers might be needed to provide the player with a decent coverage of the lawn.

Trivia
