    In Arboretum Mustila, the most significant private tree species collection in Finland, cultivation of exotic conifer species began in the 1910s. Finnish research on exotic conifers stems from the interests of commercial forestry although the focus of cultivating these conifers has shifted to horticultural and landscaping use in practice. This study is an inventory aiming to produce knowledge on the performance of conifer plantations in Mustila Arboretum. In addition, the results of the inventory are usable in targeting the selection of reproduction material in the Arboretum and they enable further discussion on benefits and possibilities of breeding exotic conifers. 41 tree species from genera Abies, Chamaecyparis, Cuprsessus, Larix, Picea, Pinus, Pseudotsuga, Thuja and Tsuga were included in the study. Yield parameters, tree quality, tree damages and phenotypic variability in important properties to horticultural landscaping use were assessed in forest stands and tree groups. 1-4 permanent circular plots were established to each forest stand for measurements and additionally phenotypic variance was estimated visually. Results of the inventory are available for the Arboretum and every single tree can be tracked even after decades. Most of the Arboretums exotic conifer plantations are suitable sources for reproduction of trees for gardens and parks. Abies balsamea, Abies koreana, Abies nephrolepis, Larix gmelinii var. japonica, Larix sibirica, Pinus peuce and Pseudotsuga menziesii var. glauca were most vital of the studied species. Stand volume exceeded 500 m3/ha within 16 species. Results of the inventory indicate that more exotic species perform well in Southern Finnish conditions than former studies have shown.

    Plants strongly affect the atmosphere of and the general feeling produced by amenity landscapes. To preserve the original impression when maintaining or renovating a landscape site, it is essential to know the plant assortment available at the time of construction. Our aim was to find out which landscape plants were popular or typical in Finland in the 1950s and how they were used in ornamental plantings. The study was confined to woody plants in public and semipublic green areas, such as parks, street plantings, playgrounds, cemeteries and shared yards. The back volumes (1950 to 1959) of the Finnish horticultural magazine Puutarha and a few other publications on garden plants and landscape design were used as the main source of information. The relative popularity of different taxa was judged by the frequency they were referred to in the literature. The results showed that even if the assortment of woody ornamentals was rather scanty in the 1950s, there were such taxa on the market that are no longer common in Finland. Domestic nurseries prospered and there seemed to be enthusiasm for trying new, sometimes not quite winter hardy species, such as Ligustrum vulgare, which was often advertised for hedges in the fifties. Some of the most popular ornamental plants were Crataegus grayana, Caragana arborescens, Syringa vulgaris and its cultivars, Salix alba sericea 'Sibirica' and the glaucous-leaved forms of Picea pungens. Hardwoods were favoured in urban settings and Tilia were the most common taxa in street tree plantings.
