Twin Sunflower

The Twin Sunflower is a two-headed Sunflower. It gives out two sun each time. It is an upgrade plant in Plants vs. Zombies, while in Plants vs. Zombies 2: It's About Time, it is a normal plant, unlocked after beating the penultimate level of Ancient Egypt.

Plants vs. Zombies
To get it, the player must buy its seed packet from Crazy Dave's Twiddydinkies for $5,000. It appears on sale after beating level 3-4, along with the Gatling Pea. It costs 150 sun to plant and must be placed on an existing Sunflower. Twin Sunflower double the sun production of the Sunflower, which means it increases from 25 sun exactly 24 seconds to 50 sun over the same amount of time.

Plants vs. Zombies Adventures
Twin Sunflower is unlocked after reclaiming The Sunny Lot. Twin Sunflower still gives out two sun each time, but its sun cost is reduced to 50 only and not an upgrade of Sunflower. This makes Twin Sunflower a very effective sun-producer for any level. If the player uses a Plant Perk on it, it will stun all the nearby zombies, in the same manner as Sunflower.

Plants vs. Zombies 2: It's About Time
Twin Sunflower is unlocked after completing Ancient Egypt - Day 24. It is not an upgrade of Sunflower and costs 125 sun in this game.

Plant Food upgrade
The Twin Sunflower instantly produces 250 sun when given Plant Food. Before the 1.7 update, it gave 225 sun when fed Plant Food. Exiting and entering a level, however, activates a glitch where Twin Sunflowers give 600 sun when fed Plant Food, but after two uses, it gives 350 sun by doing so until it reverts back to 250 sun; exiting and entering a level again will reset the glitch.

Twin Sunflower's super-chic line of ultra-expensive sunglasses has been a huge hit wherever she goes. Due to this she has been unable to travel without being swarmed by the Poppyrazzi.

Strategies
Twin Sunflowers can be used for later and longer levels that require heavier attacking plants or abilities. They're especially valuable in Survival Mode due to lack of space for many Sunflowers. Although Twin Sunflowers are not as efficient as Sunflowers, they take up half the space as Sunflowers producing the same amount of Sun, so are more helpful for levels with large numbers of zombies that require more space for offensive plants.

Use the Umbrella Leaf to protect Twin Sunflowers, especially those in the back of the lawn, against the Bungee Zombies and Catapult Zombies. However, if you have enough firepower nearby, the Bungee Zombies should not be able to survive long enough to steal the Twin Sunflowers.

In Survival Mode, you'll want at least five or six of these so that you can build up your defense quickly.

Flower Power Achievement
If you plant 10 Twin Sunflowers and keep them alive, you will earn the Flower Power Achievement. The easiest way is to get the achievement is to play an easy level. Play a Survival Level (not Endless), preferably Survival: Pool, (due to it being a level in the daytime that has six rows) and plant Sunflowers to be upgraded to Twin Sunflowers. It is recommended that you protect them with Pumpkins and Umbrella Leaves. Replace the Pumpkins when and if needed. Of course, use your usual Survival strategy for that level. All 10 Twin Sunflowers should make through to the end. Or you can play ZomBotany 2, because there are three flags. It's better to use six Gloom-shrooms and two Garlics and then keep 10 Twin Sunflowers to alive and don't let them get shot down by peas.
