Crambe cordifolia
Greater sea kale (Crambe cordifolia) is a competitor perennial herb in Supplant — a native-only buffer whose game role is set out below.
The greater sea-kale (colewort) is a large ornamental brassica with edible leaves. In battle it is a Perennial herb — a Competitor on the succession chart. It is native to East Asia, Europe and South Asia and invasive nowhere, so it only ever plays the native buffer role — there is no attacker version of this card.
Its starter attack, Rhizome Creep, is available from Lv 1 for 2 Sun and deals about 29 damage. The free once-per-battle ability, Alkaloid Reservoir, unlocks at Lv 25: Empties a season of alkaloids into the foe — saturating Poison. The advanced attack, Herbaceous Assault (Lv 40, 6 Sun), hits for about 31.
From Lv 10 it carries Basal Rosette, a flat +3 DEF at all times. At Lv 68 a second always-on trait stacks on: Contractile Roots, whose DEF climbs by 1 each checkup up to +5 across the fight as the roots pull the crown deeper.
For field gear, a Calcium/Magnesium amendment adds flat DEF, which a soft-bodied plant like this feels most; feeding it Nitrogen (N), the nutrient matching its edible leaf, pays bonus coins. Its growth habit is not recorded as a climber, so it is not Moss Pole–eligible.
Read at the snapshot level (Lv 40, where its whole kit is unlocked), it shows 84 HP and 22 ATK with 4 DEF. As a native it carries a 15% HP cushion and, while benched, projects an HP overshield bar onto your active. On defence, its DEF stays near the floor, so it relies on tempo and offence rather than soaking hits. Its opening tempo (turn 1) is 25 and its sustained tempo (turn 2 onward) 48 — making it slow to open but relentless once it gets going. Retreating it costs 12 Sun. See Stats and Native Strength for the full picture.
By Lv 100 its HP swells toward 147, but its DEF barely leaves its band at 8 — a soft-category plant stays soft no matter how much biomass it puts on. Attack reaches 39, retreat rises to 24 Sun, and its inverted tempo has sunk to a sliver, so the speed it relied on young is spent. It grows bulkier but never becomes a wall.
On the succession chart a Perennial herb is a Competitor. Competitor plants hit Ruderal categories hard (×1.5) and are resisted by Specialist categories (×0.667); against everything else the matchup is neutral. Weird categories are off the wheel entirely, so it trades neutrally with those.
It carries a distinctly lower HP floor than most of its cohort, so it is frailer than it looks, but its DEF builds over a fight through Basal Rosette and Contractile Roots. Native only — a leaf coin-earner and support herb. Because its edible part (leaf) is recorded, feeding it Nitrogen pays ×1.25 coins; any other nutrient banks ×1.25 XP instead.
It fights as a fast skirmisher until about Lv 31, after which its growing bulk and attack take over from its early speed edge.
Leveling trades speed for power. A plant’s tempo (SPD + INI, the turn-order edge) fades as it grows, while its power (HP + ATK + DEF, net of the rising Sun cost to retreat) climbs. The crossover is the level where power overtakes tempo: below it the plant is a fast skirmisher, above it a heavyweight. Shown for each stance this plant can actually hold — native adds a HP cushion, invasive an attack edge, neutral neither — with the card at its crossover and fully grown at Lv 100.
