You can only use this card name’s 1st effect once per turn.
(1) If this card is sent from the Deck to the GY by a monster effect: You can Special Summon this card, then, if you control another Plant monster, you can halve the ATK/DEF of 1 face-up monster on the field.
(2) The first time this card on the field would be destroyed by battle or card effect each turn, you can send 1 Plant monster from your Deck to the GY instead.
