En - Juniperus communis - is 'common juniper. It's the third conifer hereabouts, after gran - spruce - and fur (or tall) - pine.
The old saying goes:
"När alla enbär mogna
Blir alla flickor gifta - och trogna"
"When all juniper berries ripen
All girls will be married - and faithful"
The catch is that juniper berries take time to ripen - there are unripe green berries and ripe dark blue ones on the same twig.
(I just looked for a translation of kart in my English dictionary and it was translated as "unripe green berry", and äppelkart as "unripe apple")
