In Germany, juvenile detention is up to 24 years. Juvenile law is also not that straightforward, if it’s applicable also depends on how “childish” someone still behaves. In some cases one can be 20 and still go to an adult prison, e.g. if they’re very violent and wouldn’t fit into the education-oriented juvenile detention. On the other hand, older people who behave very childish (e.g. because of a disability) will usually not be put into an adult prison and instead get something more therapy oriented similar to juvenile detention.
Close relatives to strawberries are other similar plants like Sibbaldia. More distantly related are roses and lots of other fruits like raspberries, apples, peaches and so on. Hazelnuts are even more distantly related (not super far, but also not super close). You’re probably thinking of hazelnuts because the small seeds on strawberries are technically nuts.
