A thorny frost plant that bristles with ice spines around its stem, dealing contact damage and applying cryo to any zombie that attacks it and retaliating with a thorn burst when its toughness drops below 50%.

Details
Passively deals 15 damage and 1 cryo point per second to all zombies within adjacent tiles (contact damage). When toughness drops to 50% or below, automatically releases a one-time cryo thorn burst dealing 60 damage to all zombies in a 3x3 area. Burst can only trigger once per planting.
Snowthorn Weed is a reactive defensive plant with two damage modes: passive ice spine contact damage on any zombie that attacks it, and a one-time 60-damage cryo thorn burst when its toughness drops below 50%. Place it in front-row positions where zombies will inevitably contact it, triggering both the passive spine damage and eventually the burst. In Survival Mode, a column of Snowthorn Weeds creates a passive spine-damage barrier that chips away at zombies while they are adjacent. The half-health burst at 60 damage in a 3x3 area punishes the zombie cluster responsible for the damage reduction. Pair with Snow Lotus for combined aura slow and contact cryo from spine hits. At 100 Sun, Snowthorn Weed provides excellent defensive value for its cost especially in lanes with frequent zombie contact pressure.
Snowthorn Weed is most effective against slow melee-focused zombies that linger in adjacent tiles for extended contact time, maximizing spine damage accumulation. The thorn burst at 50% health specifically punishes the zombie group responsible for bringing it low.
✓ Strengths
Passive contact spine damage continuously harms any adjacent zombie
1.5x toughness of 1500 is high for a 100 Sun plant
Cryo point application on spine hits stacks toward freeze
One-time burst at 50% toughness deals 60 damage in 3x3 area
Excellent defensive value per sun spent
✗ Weaknesses
Contact damage only activates when zombies are adjacent - ranged attackers avoid it
Thorn burst only triggers once making replacement necessary after use
Cold-immune zombies receive no cryo stacking from spine hits
Aerial zombies bypass all contact effects
Burst cannot be saved for a strategic moment - triggers automatically at 50% health

Place in the front column to maximize zombie contact time for passive spine damage
2
Pair with Snow Lotus for combined aura slow and contact cryo from dual sources
3
Use Aqua Aloe behind it to restore toughness and delay the 50% burst trigger for a larger zombie cluster to accumulate
4
Combine with Coldsnap Bean for triple cryo stacking on front-row zombies

In Endless Mode, a front line of Snowthorn Weeds provides passive damage and burst punishment without any player management
