I really like this smaller pine tree. I saw them years ago at the Morton Arboretum and a few in England. I am not sure who designed the Aptos Village green space but they picked a great tree on one side and a bit of a mistake on the other, oh well.
The Bosnian pine develops a tight upright conical shape with a height in Bosnia of maybe 50 feet tall. The older one's I have seen are no more than 25' tall. There are several cultivars in the trade but most are dwarf selections, though there is one that was really dark green and compact. But I'm not sure if it's one of those so I'll stick with the species. This image is the Aptos Village tree taken 6/24.
Bark is whitish gray, The older name for this species in Pinus leucodermis (white skin.)
There is a cultivar named 'Compact Gem' which the plant in Aptos could be one though this cultivar is a bit rounded.
Misidentification: Austrian pine for sure, but the cones on the Austrian pine are not purple and are larger, the needles are longer as well.
