Sunberry

The Sunberry is a plant introduced in Roman Empire that can be bought for a price of 129 gems. Sunberries are instant-use plants that produce 250 sun when planted, giving a profit of 200 sun.

Suburban Almanac Entry
Sunberry is devoted to the sun. The sun is her religion. The sun is her GOD. "ALL HAIL THE MIGHTY SUN!" yells Sunberry. Sunberry has thought long and hard about what she wants to achieve in this world. Should she shoot zombies with sun? No, that's just sun bashing. Should she protect those planted with sun from being eaten? Maybe, but that doesn't get to the root of the cause now, does it? No. Sunberry knows what she has to do. She must sacrifice herself to the great sun god. "Yes, yes, appease the mighty deity's great appetite" says Sunberry, "that is the only way." Her friends have tried to convince her otherwise, but she won't listen. "My mind is set!" Well, at least it beats a potential Groaneo and Juliet situation with Ra Zombie. That wouldn't end well for sure.

Strategies
Sunberry produces about as much sun on average as 5 Sunflowers, so it is possible to use Sunberries exclusively as a sun production method when space is of concern. If this is done, less sun will be produced compared to other methods, such as two rows of Sunflowers, a row of Twin Sunflowers or a row of Sun-shrooms. However, there is a huge advantage to being able to save space and not have to replace eaten sun-production plants. Sunberries can also be brought alongside other sun-producing plants to give a huge boost to sun production and minimise dependence on placed sun-producing plants. The Sunberry can also provide a much-needed boost at the start of the game when there are insufficient sun-producing plants to defend against early zombies.

Keep in mind, that the use of the Sunberry requires continual replanting, so this must be observed carefully by the player.

Trivia

 * The Sunberry is based off the solanum retroflexum.
 * Groaneo and Juliet is a pun on Shakespeare's tragic play Romeo and Juliet. It is a joke on how a romantic relationship could develop between Sunberry and Ra Zombie as they both worship the sun. Of course, they would be on opposite sides of enemy 'families' so to speak, similar to the story of Romeo and Juliet.
