For all plants all the effects apply when planted on a relic, so also for instant use ( calabash ). It just activates the relic and the plant get burned, get frozen in time or get a shield (which is not really helpfull for a instant use plant). The relics stay revealed forever untill they get used that is.

Easy way too not burn or freeze your instant use plants is too just not plant on relics. Or plant a cheap plant first before if you really want to.
