“…Outdoor palm species grown in the EU as ornamental plants differ in their requirements on soil types, moisture, humidity, cold tolerance, air pollution, exposition and ornamental value (Broschat et al, 2014). Planting positions for palms are usually previously assessed, with possible amelioration actions (Hosek and Roloff, 2016). Generally, they have higher growth (up to 5-6 m) but dwarf species (up to 2 m) are also used.…”

This technical report was prepared in the context of EFSA's mandate on plant pest surveillance (M-2020-0114), at the request of the European Commission. Its purpose is to support the Member States in the planning and preparation of crop-based surveys of regulated pests in line with Commission Implementing Regulation (EU) 2019/2072. In particular, the report includes the list of palms and ornamental species reported as hosts of regulated pests within the scope of grant GP/EFSA/PLANTS/2022/10 'Development of crop-based survey tools for plant pests of fruit trees, conifers, and palms and ornamentals in the EU'. A list of pests associated with palms and ornamentals is provided. In addition, the occurrence, phenology, main uses, management, distribution and climate suitability of palms and ornamentals in the EU is elaborated. Finally, the regulatory requirements and data on trade and import for palms and ornamentals are reported. In total, 111 palm tree species are reported as hosts of at least one of the regulated pests. Among them, only three are native to the EU, four are nonnative but locally abundant in the EU, while 104 palm species are considered to be very rare or absent in the EU. With the exception of the date palm, all palm species present in the EU are used for ornamental purposes. The ornamental crop group comprises 36 plant species, of which three are native to the EU, 14 are non-native but locally abundant in the EU, and 19 are considered to be absent or very rare in the EU. Ornamentals are often cultivated in production systems ranging from low shelters or tunnels to high-technology greenhouses or glasshouses. The most common ornamental plants in the EU that are grown as potted plants, seedlings, bulbs, corms or cut flowers include chrysanthemums, carnations, dahlias, pelargonium, gerbera and violas. Ornamentals are cultivated in all Member States; the Netherlands being by far the biggest producer.

“…However, Broschat [62] observed that planting season in southern Florida may not be important as warm temperatures allow for near year-round root and shoot elongation. Hosek and Roloff [63] assessed urban site factors (aboveground space and distance to roadway) but found weak or no correlation with palm health.…”

Urban tree planting initiatives can experience high levels of mortality during establishment years. Mortality tied to the stresses of transplanting can be partially negated or exacerbated depending on the species selected, nursery materials used, site conditions present, and management practices employed. Past research has quantified post-planting survival, health, and growth. However, varying climates, species, land use types, and management practices warrant additional region-specific research. The purpose of this study is to assess the success of plantings along Florida highways and identify species, site, and management factors related to tree and palm health and establishment. Results show high annual establishment survival (98.5%) across 21 planting projects ranging from 9 to 58 months after installation, (n = 2711). For transplanted palms, the presence of on-site irrigation significantly improved establishment from 96.2% to 99.4%. No establishment differences were detected with regard to irrigation treatment for small-stature trees, shade trees, and conifers. Additionally, there were significant differences in tree health response among tree groups given species, management, and site factors.

“…Landscape trees and palms are commonly planted in many cities for scenic views and are maintained with frequent irrigation. Palms can be found planted alongside trees in many cities, such as Los Angeles in USA, Olhão in Portugal and Bangalore in India [12][13][14]. To obtain the information for effective maintenance of urban tree and palm species, one can explore how their physiological parameters respond to various environmental conditions.…”

An Urban Tree (Tabebuia argentea) Exhibits Higher Sensitivity to Environmental Conditions than an Urban Palm (Ptychosperma macarthurii) Growing in the Same Roof Garden: An Implication for Sustainable Urban Water Use

et al. 2023

Roof gardening is popular for increasing green space in cities due to the restricted urban areas. However, when watering plants on a roof garden, one should consider loading capacity of the roof, which may limit water supply to the plants therein. To improve the efficiency in irrigating trees in a roof garden, we evaluated plant water status, represented by midday leaf water potential (ΨL), and leaf gas exchange parameters including stomatal conductance (gs) and net photosynthesis (An) of a tree (Tabebuia argentea, Ta) and a palm (Ptychosperma macarthurii, Pm) species, which dominate the garden. The ΨL mediated responses of gs and An, regulating plant water use and growth, to soil moisture. Results showed that ΨL of Ta significantly varied with changes in soil moisture, being low at low and high soil moisture. Nevertheless, gs of Ta linearly decreased when ΨL increased, suggesting a stronger response of gs to atmospheric demand. In contrast, no significant responses among the study variables were observed in Pm. For both species, An initially increased with gs and saturated after gs reached 200 mmol m-2 s-1, indicating similar stomatal regulation on atmospheric carbon dioxide absorption. The limited space for root growth and the location with surrounded building walls contributed to unconventional response patterns observed in Ta. Nonetheless, our results suggested that Ta was more sensitive to changing environments, especially the atmospheric demand, than Pm. Additionally, Ta should be irrigated during daytime and when atmospheric vapor pressure deficit is less than 2.6 kPa to allow high photosynthesis and evaporative cooling while Pm may be watered less frequently to reduce the roof’s loading and save water. This initial investigation implied that maintaining urban trees using appropriate irrigation that is specific to tree species is the key to maximize benefits from urban trees and optimize urban water use.
