This isn't the best picture I've ever taken, but I hope it's good enough that you can identify the plant.
Stonecrop is a succulent herb that includes perhaps 600 species -- mostly in the North Temperate Zone. Many make excellent garden subjects, but they are usually not found in most nursery centers and are only available from the various rock garden societies. The genus name is from the ancient Latin term, sedere, "to sit," referring to their low-spreading habit or possibly from sedere, "to quiet," alluding to their supposed sedative properties.
Sedum acre ("biting stonecrop") contains high quantities of piperidine alkaloids [namely (+)-sedridine, (-)-sedamine, sedinone and isopelletierine] which give it a sharp, peppery and acrid taste and make it somewhat toxic. Depending on the amount consumed, it may cause irritations of the mucous membranes, cramps, paralysis, and respiratory paralysis. In ancient Greece, Sedum acre was used to treat epilepsy and skin disease, as well as inducing miscarriage.

I'm not sure of Finnish species, but it looks like a Stonecrop, possibly Sedum acre,known as Bitter Stonecrop a member of the crassulacaea family. Hope this helps.
thank you! you are correct!
