“…Such bud and leaf sprouting time is at least a dozen days later than that noted in many Pimpinellifolias (R. pimpinellifolia) [24] and Rugosas (R. rugosa) [25,30] as well as in numerous ground covers [26]. At the time when in most Pimpinellifolias (R. pimpinellifolia) [24] and Rugosas (R. rugosa) [25,30] as well as in numerous ground covers [26] leaves had already developed and young shoots had started their growth, in the Gallicas buds just opened and the leaf development process only started.…”

“…A few cultivars ('Charles de Mills', 'Complicata', 'Officinalis', 'Splendens', 'Versicolor', 'Violacea') produce decorative hips. The Gallicas start flowering a few days later than Rugosas [25,30] and Pimpinellifolias [24], but earlier than classic ground covers [26].…”

“…Grootendorst', 'Frau Dagmar Hastrup', 'Rugeaux du Japon' [25]. They show, however, much higher frost resistance than ground covers [26], English roses [27], hybrid teas, floribundas, shrub roses, ramblers or climbers growing in the same Collection of PAS BG CBDC, in which shoots often freeze to the ground level during severe winters [28]. Even small freezing classified as level 1 damage according to ukaszewicz's scale (1992) results in the need to prune down to the healthy tissues in most rose shrubs of modern rose cultivars, while freezing at a level of 6 according to this scale often in the need to cut right down to the ground level.…”

<em>Rosa gallica</em> is a native species under strict protection and its cultivars are practically unknown in Poland. The aim of the observations was to evaluate the possibilities of growing the studied cultivars in the climate of Central Poland. In the years 2000–2012, observations were conducted of shrubs derived from the French rose (<em>R. gallica</em> L.) gathered in the Collection of Rose Cultivars of the PAS Botanical Garden CBDC in Powsin, Poland. 13 cultivars were studied: ‘Ambroise Paré’, ‘Belle Herminie’, ‘Camaïeux’, ‘Cardinal de Richelieu’, ‘Charles de Mills’, ‘Complicata’, ‘Duchesse d’Angoulême’, ‘Duchesse de Montebello’, ‘Officinalis’, ‘Splendens’, ‘Tuscany Superb’, ‘Versicolor’, and ‘Violacea’. Every year, frost damage to shrubs, the date of bud breaking and leaf development as well as the dates of initial, full and final flowering were recorded and the presence of symptoms of damage from diseases was observed. During the observation years, periods of weather conditions unfavorable for roses often occurred, both in autumn-winter-spring and in summer. Only small differences were observed in winter hardiness, development during the growing season, and blooming period. The majority of the studied rose cultivars overwinter without frost damage, even through severe winters. The shrubs begin their growth late, usually until the second half of April. Gallicas start flowering early, in the third decade of May – first decade of June. Most Gallicas should find a wider application as shrubs or hedges for parks, green areas in cities, historical places, or home gardens. They are recommendable for their high resistance to frost and diseases as well as for their small size.

“…The climber roses were evaluated from the year of planting to the end of 2017 (Table 1). The degree of frost damage was noted every spring according to a 0-7 point valuation scale developed in the Botanical Garden for rose research [38][39][40][41][42][43][44][45], as below: 0 -plants without frost damage; 1 -buds develop, but darkened vascular bundles on stem cross-section; 2 -buds on stem frost-damaged; 3 -the tips of one-year-old shoot frosted; 4 -one-year-old shoots overall frosted or solely their base living; 5 -two-year-old and older shoots frosted; 6 -all the shoots frosted to the ground surface; 7 -shrubs frosted, without young shoots. The chosen phenological stages were recorded according to the basic principles of the BBCH (Biologische Bundesortenamt, CHemische Industrie) scale [13,46] after winter dormancy or the resting period (BBCH scale 00) from the beginning of bud break to flowering, according to chosen points of the BBCH scale described for cultivated roses [12].…”

The genetic pool of valuable old ornamental cultivars and their in situ maintenance may be threated by climate change. Meanwhile, the ornamental plants like roses make up an important share of both gardens and urban green spaces, where they are particularly vulnerable to multistress growth conditions. The aim of this research was to evaluate the effect of changing climatic conditions on growth and flowering of 11 historic climber roses through long-term studies (2000-2017) conducted in Central Europe. The evaluation of plants consisted of assessment of frost damage and the timing of early phenological stages (starting of bud break, leaf unfolding) as well as gathering data on beginning, fullness and end of flowering and its abundance. Frost damage was not recorded in any year only in ‘Mme Plantier’, and did not occur for any cultivar after the winter in the years 2007, 2008, and 2014. Only a little damage to one-year shoots was recorded after the winter in the years 2015-2017. Frost damage to ‘Alberic Barbier’, ‘Albertine’, ‘Chaplin's Pink Climber’, ‘Orange Triumph clg’ and ‘Venusta Pendula’ led to pruning to ground level in every year excluding those listed above. Frost damage of once blooming roses limited their flowering; however, the many-year data-sets showed a trend for decreased frost damage and improved abundance of flowering, and these results can be interpreted as a response to the increase of average air temperature. The timing of bud breaking and leaf development in all climber roses was strictly correlated with average air temperature in the dormancy period. The reactions of climber roses to weather conditions confirmed the influence of climatic changes on ornamental crop plants in Central Europe, introducing the potential possibility for the wider application of climber roses, but without certainty of flowering every year.

“…Numerous publications, as well as observations of growth and fl owering in the climatic conditions of Central Poland in the Polish Academy of Sciences Botanical Garden in Powsin, Warsaw, indicate the great decorative value of many park rose cultivars (Monder 2007a(Monder , b, 2011(Monder , 2012a(Monder , 2014. They exhibit higher resistance to frost and winter hardiness than the recommended contemporary ground cover roses, which is a determinant of successful cultivation (Monder 2004(Monder , 2008(Monder , 2012c. Their decorative qualities, especially fl owers and their fragrance, are high.…”

Parkowe róże historyczne w przestrzeni miejskiej. Tradycja uprawy róż sięga czasów antycznych i do dziś są one jedną z najważniejszych roślin ozdobnych. Liczne gatunki i odmiany starszego pochodzenia mają duże walory dekoracyjne, a ponadto spełniają warunki stawiane roślinom przeznaczonym do sadzenia w mieście: są bardzo odporne na warunki zimowe i rosną dobrze na własnych korzeniach; tolerują upały oraz susze; są wystarczająco odporne na choroby i szkodniki; mają zróżnicowane i nieduże wymagania glebowe; „czysto" przekwitają; mają niewielkie wymagania pielęgnacyjne sprzyjające ograniczeniu nakładów finansowych. Istotny jest ich udział w ekosystemach miejskich: gęste i kolczaste krzewy róż stanowią schronienie, a pseudo-owoce pożywienie dla ptaków i małych ssaków; nektar i pyłek kwiatowy wabią owady. W Polsce nie ma tradycji stosowania róż historycznych w zieleni publicznej. Możliwy odpowiedni dobór róż historycznych o wymienionych korzystnych cechach dotyczy terenów zurbanizowanych, w tym na przydroża, do zieleńców i parków, a przede wszystkim do założeń historycznych i zabytkowych. Wiele róż z tej grupy jest zalecanych do założeń o charakterze naturalistycznym. Wśród nich są taksony odpowiednie do stosowania w nasadzeń rabatowych, grupowych, jako żywopłoty nieformowane, do kompozycji z innymi gatunkami roślin na stanowiskach słonecznych lub częściowo zacienionych.
