“…Biogeography addresses questions related to where organisms occur across space and time as well as why certain species occur in given areas and why others do not (Norris, 2011). Phytogeography is the branch of biogeography that is concerned with the distributions of plant taxa and the factors that contribute to those distributions (Lomolino et al, 2006).…”

“…Although ecological planting styles, i.e. geographic (aiming to recreate vegetation types or their essential characteristics from areas around the world) or physiognomic (aiming to recreate natural characteristics/patterns and vegetation function, but with little regard to the geographic origin of the component species) have been present in garden design for about 200 years (Flynn, 2009), horticulture and biogeography in common practice still seem to be an odd couple (Norris, 2011). However, inferences from biogeography can lead horticulturists to make regionally adapted selections for cultivation and utilise genetic resources from a particular geographic area (native plants) to enhance the productivity or adaptability of cultivated plants (Norris, 2011).…”

The design and creation of the Ionian Islands Unique Rock Garden (IIURG), an innovative plant display in Thessaloniki, Greece, is described. This includes seven naturalistic rock gardens hosting twenty-two plant taxa of conservation priority. The unique nature of the IIURG is based on two features: the emulation of the natural geographic characteristics of the Ionian Islands (Greece) and the integration of the endemic elements of the islands’ native flora, focusing on the biogeographical significance of each. In this way, the IIURG represents an innovative concept in the horticulture of botanic gardens which embodies the natural biogeography and its basic concepts such as ‘islands’, ‘native’ and ‘endemism’. In aesthetic terms the garden looks like a natural sculpture and functions as a focal point. It is a carefully constructed plant display using environmentally sustainable principles with low levels of maintenance and irrigation required. The aim is that the IIURG should be used as a useful tool for awareness-raising on the conservation of prioritised plants.

“…Many native shrubs have proven amenable to asexual propagation (Cartabiano and Lubell, 2013) and could therefore be more widely produced in the industry, whereas others like eastern leatherwood (Dirca palustris) are recalcitrant and unlikely to reach even those consumers keenly interested in native plants (Norris, 2011). Recently, the prospects for greater commercialization of a popular native plant of the northeastern United States, sweetfern (Comptonia peregrina), have been increased by improved methods to propagate it commercially (Gardner et al, 2019;Lubell and Brand, 2011).…”

Sweetgale (Myrica gale), rhodora (Rhododendron canadense), and catberry (Ilex mucronata) are shrubs of eastern North America that may have potential for broader use in horticultural landscapes. Because information on their vegetative propagation is scarce, we conducted experiments over 2 years to evaluate the effects of cutting collection date, wounding, substrate composition, and the concentration of applied potassium salt of indole-3-butyric acid (K-IBA) on rooting of each species. In 2015, we collected cuttings of each species on three dates to obtain both softwood and semihardwood cuttings. Cuttings were unwounded or wounded with a razor blade, and treated by dipping into water containing K-IBA at concentrations ranging from 0 to 15,000 mg·L−1, after which they were inserted into a substrate of 3:1 perlite:peat (by volume) and placed under intermittent mist. In 2016, semihardwood cuttings of each species were all wounded, treated with K-IBA from 0 to 15,000 mg·L−1, and inserted into substrates of 100%, 75%, or 50% perlite, with the remaining volume occupied by peat. In both years, the greatest percentage of sweetgale cuttings rooted when no K-IBA was applied. K-IBA application also reduced root ratings, root dry weights, and root lengths of sweetgale. For rhodora and catberry, maximal responses for all measures of rooting occurred when 5000 to 15,000 mg·L−1 K-IBA was applied. We recommend that growers use no exogenous auxin to propagate sweetgale, and 5000 to 10,000 mg·L−1 K-IBA to propagate rhodora and catberry. Cuttings of all three species can be collected from softwood or semihardwood shoots. Finally, sweetgale can be rooted in perlite alone, whereas rhodora and catberry required the addition of peatmoss for satisfactory root development.
