    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.

    Ornamental Malus cultivars with pendulous branches are called weeping or hanging crabapples. This report is part of a project aimed at identification and characterization of weeping crabapple clones. We used DNA-fingerprinting techniques, morphological characters and historical records to unravel the name and origin of 13 Finnish and Swedish weeping crabapple specimens. One Swedish and four Finnish trees were identified as Malus prunifolia ‘Pendula’, which originated at the experimental station of the Royal Swedish Academy of Agriculture in Stockholm in 1859 or 1860. Two old Swedish trees were concluded to represent M. p. ‘Pendula Nova’, another weeping clone born in the same station in 1873 and regarded as extinct long ago. Malus ‘Hyvingiensis’ was verified as a unique, triploid cultivar grown from seed at the Finnish State Railways Nurseries, Hyvinkää around 1900. DNA-fingerprinting revealed several mislabellings among both the local and the reference samples. Three of the local trees and two of the reference accessions remained unidentified. The three historical cultivars will be preserved in the national gene banks.

    Puu-Käpylä (“Wooden Käpylä”), a neighbourhood of Helsinki, is the earliest example of the Garden City Movement in Finland. The suburb of valuable wooden architecture was built between 1920 and 1925, with the aim to provide a healthy housing area for working-class families with many children. The houses were erected by a co-operative (Käpylän kansanasunnot, “People?s Dwellings”) and they are protected by the city plan since 1960?s. However, the historical value of the sheltered courtyards has not been investigated. The aim of this study was to survey the garden flora of Puu-Käpylä and to evaluate the authenticity of the courtyard gardens. The survey covered the area of one residential quarter (1.2 ha) with twelve 2-storey semi-detached timber houses arranged around a common yard, which was originally appointed for the tenants? vegetable gardens. The houses are still rented, and each flat is allowed a small lot of the courtyard for cultivation. A complete list was made of all perennial, ornamental plant taxa present in the quarter. Spring bulbs were missed due to the timing of the survey. Generally, the plants were recorded on species level, with the exception of common lilacs, shrub roses, irises and peonies that were thoroughly studied for cultivar identification. It was assumed that plants initially grown in the courtyard could be distinguished by studying Finnish garden magazines, books and nursery catalogues published in the 1920?s and by comparing the present vegetation to surviving documents from the quarter. The total number of ornamental plant taxa identified was 172, of which 17 were trees, 47 shrubs, 7 climbers and 101 herbaceous perennials. The results indicated that a major part of the shrubs, climbers and perennials presumably originated from the 1970?s or later, whereas ca. 70 % of the tree specimens were deemed as original. The survey disclosed a heritage variety of common lilac, resembling cultivar „Prince Notger?, a specific peony taxon, Paeonia humilis Retz., cultivated in Nordic countries since long ago, and a few historic iris varieties. Well-preserved design elements included front gardens on one side of the quarter, a maple alley on another side as well as trees at the garden gates. Old garden books and magazines did not shed much light on the Finnish garden flora commonly used in the period when Puu-Käpylä was built. However, they gave a valuable picture of contemporary planting design. Nursery catalogues offered insight into the assortment of ornamental plants traded in the 1920?s. Conclusions on the authenticity of the current flora were mainly drawn on the basis of old photographs and a vegetation survey map drawn in the 1970?s. This study revealed a need for standardization of syrvey methods applied when investigating garden floras. Uniform survey techniques would make the results comparable and enable a future compilation of data from e.g. historic gardens.
