Ironwood

Ironwood is the seventh plant unlocked in Lightning Ridge in Plants vs. Zombies: Lost World, after beating Level 13A. Ironwood is essentially a Tall-nut with the additional ability to withstand 2 Gargantuar smashes (which are reduced to 4000 DPS worth of damage on Ironwood) and a cheaper cost, but, however, one downside of Ironwood is that, after 20 seconds, Ironwood will begin to rust and take 2.5 times more damage than usual. This rusting process can be sped up by water, where rain (like the rain in Lightning Ridge) will cause him to rust 1.5 times faster, and any water splashes (e.g. from Firefighter Zombie) will reduce the rusting time by 3 seconds.
In order to prevent Ironwood from rusting, electricity and/or fire-based attacks from plants need to pass by Ironwood to encourage the rusting process to revert by 1 second for every 20 DPS worth of attacks. If Ironwood is already rusted, 100 DPS worth of electricity and/or fire-based attacks is required to remove the rust (this will reset the rusting timer back to 20 seconds).
==Origins==
Ironwood's name is based on the same common name that is used for woods or plants that are known to be very hard or have a higher density than water. The word 'iron' in his name refers to the iron that he utilizes for his defense, and his rust being removed from electricity and fire refers to how rust in real life can be chemically reduced with high energy sources (i.e. electricity and fire) to form back iron.
==Almanac entry==
Ironwood
Sun cost: 75
Recharge: Sluggish
A defensive plant with very high health and the ability to block flying zombies for a relatively cheap cost, but can rust over time, especially in the presence of water.
Special: Withstands 2 Gargantuar attacks
Special: Electricity and fire attacks can reverse the rusting process
Ironwood now has second thoughts on whether welding a bunch of iron sheets around himself was a good idea. In fact, he’s starting to regret it quite a bit now. Such a silly idea, isn’t it? Of all things, he chose to plaster himself with iron all over his face instead of following his brother, Stainless Steelwood.
==Upgrades==
===Plant Food power===
When fed Plant Food, Ironwood will regenerate all his health and gain stainless steel armour that protects Ironwood from rusting until the armour is destroyed. The armour can withstand 8000 DPS and 2 Gargantuar smashes (damage from Gargantuars is reduced to 4000 DPS).

==Strategies==
Ironwood on their own is not a very good defensive plant as they will eventually take significantly much more damage from zombies once they rust, and requires support from other plants, namely electric and/or fire plants, to prevent them from rusting in order to be effective. This makes Ironwood a situational plant that would tend to synergize more well with defenses that utilize mainly electric or fire plants rather than defenses that use other plants, so if you would prefer to use Ironwood over Tall-nut, try to pair them up with electric and/or fire plants. Take note that water sources will speed up Ironwood's rusting process, so in the presence of water (e.g. the rain in the area which Ironwood is obtained from or water attacks from zombies), it is recommended to build a stable electric/fire offense before placing Ironwood.
