Like its modern counterpart, Primal Sunflower's design is based on the Helianthus annuus, known as the common sunflower.
Sun cost: 75
Primal Sunflowers pop out large suns instead of regular ones.
Sun Production: Large suns
Primal Sunflower is new to all this sun-giving business, so be patient with her. She's an early adopter of the all-you-can-stuff-yourself buffet style of sun production.
When given Plant Food, Primal Sunflower generates three big suns worth 225 sun in total. The amount of sun produced is identical to Sun-shroom's Plant Food ability.
Primal Sunflower serves the middle ground between Sunflower and Twin Sunflower, functioning identically to a fully grown Sun-shroom both in sun production and Plant Food ability. Therefore, the choice between Primal Sunflower and Sun-shroom is entirely up to the player: The former has full production capability from the start but costs more to build, while the latter is more disposable and can be planted in larger amounts early on, but takes a long period of time to grow.
For Endless Zones, the player may bring Twin Sunflower along so that the sun production would be faster and would be more conserving to handle for the player to set their defenses up.
- It is the second plant to create large suns, the first being a third-stage Sun-shroom.
- Primal Sunflower is one of the six plants based on the common sunflower, the others being Sunflower, Twin Sunflower, Triplet Sunflower, Sunflower Singer, and Power Flower.
- Primal Sunflower currently can be used in almost all Last Stand and Sun Bombs levels, with the only exception being the levels in Jurassic Marsh.
- One of Primal Sunflower's petals appears to have been cut.
