“…The performance of native Mediterranean plants on green roofs could be improved by adopting a plant community instead of a monoculture. Varela-Stasinopoulou et al [127] analyzed the growth, flowering, and self-reproduction rate of three plant communities, artificially created and made up of native Mediterranean plants, placed in substrates of different depths (8 and 15 cm) and with two irrigation regimes (high, 20% ETo and low, 10% ETo). The plant communities simulated those on the islands of Crete and Greece.…”

In recent years, owing to intense urbanization and global change with the consequent extreme climate effects, interest in green roofs, even extensive ones, in the Mediterranean environment has increased. To this end, the choice of plant species is crucial because, owing to the identification of the most suitable plants, it will be possible to expand this type of green infrastructure and increase its ecosystem services in the urban environment. In this context, the objective of the review, through a critical analysis of some of the references on the topic, is to identify suitable criteria for plant species selection that are simple to apply and able to respond to the need to have plants capable of surviving, ensuring a suitable aesthetic effect, and providing essential ecosystem services. We also investigated whether, and to what extent, associations of different species can better adapt to the difficult environmental conditions of Mediterranean green roofs. Two possible strategies to identify the plant idiotype were analyzed: the analysis of plants present in habitat analogues or the identification of morpho-functional characters capable of discriminating the response to abiotic stress, and in particular to drought stress. The use of plant communities, rather than a single species, seems capable of improving aesthetic effects, plant survival, and ecosystem services.

“…All the above morphological characteristics make evident the expediency of its inclusion in the floricultural industry for the production of potted plants, landscape plants and cut flowers, as similar shrubs of small stature [5][6][7][8][9][10][11][12][13]. E. cretica is the second species of the genus native to Greece, endemic but quite common on the island of Crete, which also has strong potential for use as a new floricultural crop [14] and has been studied as a member of plant communities for use in urban, Mediterranean, green roofs [15].…”

The introduction of new ornamental species is a challenge for the floriculture industry. Ebenus sibthorpii is an endemic species of Greece, with a strong ornamental potential. To the best of our knowledge, there are no studies on the in vitro propagation of this species. Therefore, the current study aimed to determine the possibility of micropropagation of Ebenus sibthorpii as a first step for its introduction into the floriculture industry. A preliminary study on the germination ability of the species was also conducted on 1/2-strength Murashige and Skoog medium (MS/2), in the range of 5–35 °C. Seeds germinated at 46–64% indifferently of temperature between the range of 10–30 °C. In vitro cultures were successfully established (77–80% explant response) from single-node explants excised from seedlings, on MS medium either hormone-free (Hf) or supplemented with 6-benzyladenine (BA) at 0.5 and 1 mg L−1. The subsequent multiplication stage involved subcultures in MS medium either Hf or supplemented with various cytokinin types and concentrations, while the combination of 0.01 mg L−1 naphthaleneacetic acid (NAA) with BA was also tested. Τhe highest multiplication indices (3.6–4.6) were observed in media containing BA at 0.1–0.5 mg L−1, regardless of NAA presence, and in those with 0.5 mg L−1 ZEA or 1 mg L−1 TDZ. The highest number of shoots were formed in TDZ media, but almost half of them did not elongate. To address this, a two-fold culture was developed, where micro-shoots produced on TDZ media were transferred to Hf, MS or MS/2 medium to elongate. Thus, the highest multiplication index (16.4) was achieved when micro-shoots from 1 mg L−1 TDZ medium were transferred to MS medium. The present study could be the basis of further exploitation and conservation of E. sibthorpii.
