What's a jam, a jelly or a marmalade seems to vary even between English-speaking countries, even more so outside the Anglosphere.
This elderflower marmalade is admittedly an orange and elderflower marmalade. It's a spreadable semi-solid orange concoction with orange peels, enriched with elderflower juice. Available at an IKEA near you.
IKEA also sells delicious elderflower juice concentrate. It's supposed to be mixed 1+4 with water, but I highly recommend mixing it 1+1+1 juice+water+gin for an invigorating summer afternoon lemonade.
