Good morning! I see that I will have to devote myself even more to bellflowers. Otherwise, bellflowers are my love besides alpine sow-thistles, to which I devote myself the most. But essentially, in two years I haven't moved forward. I haven't found a handbook by our authors that devotes itself more to the genus Campanula - I mean species that grow here - I mean the alpine area.
We roughly distinguish tall-growing and low-growing ones. Many tall-growing ones also grow in valleys. The most characteristic are koprivasta, bolonska, razprostrta, klasasta, breskovolistna, repuščevolistna. We also find klopčasta, which we also grow in gardens. All of these we find in mid-mountains and even higher. Brkato, we find somehow higher - it can be found lower too - I don't distinguish it yet. Srhkodlakava is very similar to klopčasta.
There are many low bellflowers on our mid-mountain and high-mountain pastures, on rocks, in rock fissures, scree edges, among dwarf pines, among tall stems.
Of course, we best know zoisova, which has a different flower from the others and cannot be confused with the others. Distinguishing the others is already harder. They differ primarily by leaves, stem height, one or more flowers per stem, leaf rosette. The flowers will seem very similar at first glance. Some have only one flower per stem, others have more flowers and branched stems. The most common are trebušasta, rušnata, scheuchzerjeva, okroglolistna, karnijska or lanolistna - for this one characteristic grassy leaves and we cannot confuse it, witasekina. These we should find most often. Also mentioned are beckova - rare sites, alpska - completely unknown to me - not confirmed here, izrodna - Trnovo Forest, justinova - area of Škocjan Caves, marchesettijeva - Trnovo Forest. I haven't seen these last three yet.
A speciality is also klasasta - violet color - rare - in the Luknja area in Vrata and of course similar white - šopasta, which also has a subspecies.
Outside Slovenia there are even more others.
