The adaptation to the climate and soil conditions [email protected] of the region where they grow increases the chances of living compared to other exotic species; the cost of maintenance is DOI low compared to other types. Our country is extremely rich https://doi.org/10.46291/ISPECJASv ol4iss2pp125-136 about natural plants. The aim of this study is to investigate the natural geophyte species that growing in Siirt province in southeastern Turkey about possibilities of using landscape Geliş Tarihi: 15/02/2020 designs. Firstly a literature review was made on the subject. Kabul Tarihi: 20/04/2020 Afterwards, the geophyte species growing in Siirt were investigated and their possibilities of using in different landscape design areas were utilized about their various characteristics. Accordingly, 27.7% of the 54 geofit species growing in Siirt are suitable for use as medicinal and aromatic plants, 40.8% are in flower parters, 9.3% are in refuges and 24% are in natural and artificial water sides. %63 of them are suitable for use for exhibition and demonstration purposes and 72.2% of them are suitable for use in rock gardens.

Plants, which are one of the indispensable al.

(1991) the structural environments we live and approximately 800 of this number is nature. Plants have been used for food, fuel composed of geophyte plants (Güner, and medical purposes due to their many 2006). Geofits are found in almost every characteristics from past to present, and part of the world but their origin is accepted with their contribution to human life and as the Mediterranean basin (Ekim and comfort, they have been tried to be depicted Koyuncu, 1992; Seyidoğlu, 2009; from natural samples in the landscape. They Kılıçaslan and Dönmez, 2016). have entered our daily life with planting The aim of this study is to investigate the design applications (Atik et al., 2013). usage possibilities of the natural geophyte Turkey, has a huge biodiversity potential species that growing in Siirt province in from the point of cultural and natural landscape architecture. diversity. This diversity is called plant MATERIAL and METHOD genetic resources and so that Anatolia, The main material of the study is the Mediterranean and Near East are accepted geophyte species found in the natural as a gene center. Turkey is placed near the landscape of Siirt province. Siirt province is top in the location because of its natural one of the 9 provinces in the Southeastern plant diversity. The reasons for this richness Anatolia Region. It is a rich city in terms of include climate differences, topographic natural and historical values like the other variations, geological and provinces of our country. As a result of the geomorphological variations, different climatic and topographic characteristics of water environment variations such as sea, the geography it is located in, there are 54 lake, river, altitude differences ranging geophyte species belonging to 6 families in from 0-5000 m, and being located at the the province and 7 of these species are junction of three different geography endemic (Figure 1). regions (Ekim, 2005; Kılıçaslan and 261 ISPEC Tarım Bilimleri Dergisi E-ISSN:2717-7238 ISPEC Journal of Agr.

Endemic geophyte species growing in Siirt (Top row left to right: Fritillaria armena Boiss., Ophrys cilicica, Hycantella siirtensis; bottom row left to right: Crocus biflorus ssp. pseudonubigena, Ophrys phrygia, Crocus karduchorum, Ophrys bornmullerie) The study was performed in three stages. In edge, use for exhibition and demonstration the first stage, natural plant species of Siirt purposes, use in rock gardens) as in province were examined and information Kılıçaslan and Dönmez (2016). In the last about the geophytes which have a potential stage, all available data were evaluated in in terms of endemic species diversity was terms of landscape architecture. collected. In the second stage, the RESULTS AND DISCUSSION information related to these geophytes was Geophytes (bulb plants) and their use in evaluated and a table was created by landscape architecture works considering the possibilities of using them The term geophyte, first used by Danish in landscape design for 10 features (it is or botanist Christian Raunkier (Ekim and not endemic, flower colour, blossoming Koyuncu, 1992), is found in Angiospermae time (from month to month), medical and from Spermatophyta. This group includes aromatic use, shade and semi-shade monocotyledonous and dicotyledonous resistance, use in flower beds, use at species, which are divided into two groups medians, use at natural and artificial water's as bulbous and tuberous plants. In addition, 262 ISPEC Tarım Bilimleri Dergisi E-ISSN:2717-7238 ISPEC Journal of Agr.

According to Seyidoğlu (2009) and and so on by many researchers (De Hertogh Onat (2012) the use of geophytes in and Le Nard, 1993; Zencirkıran, 2002; landscape designs is as follows (Kılıçaslan Kılıçaslan and Dönmez, 2016). and Dönmez; 2016): The first salient features of the plants that Due to their variety of species and can be used in a landscape design are size, form, planted at different periods, geophytes use texture and color. Among these, especially at curb plantings. plant size and color are the first perceived They can effective appearances in single or features compared to other features. People groups with shrub groups or herbaceous at firstly look at the appearance of the plants, curb plantings (Rees, 1992; Giles and so the size and color of the plants directly Cornwell, 2004; Evans, 2005; Alp and affects the interestingness and all the frame Asur, 2006). of the design. A person who feels a In grass lands, spring flowering species are successful design in terms of color, scale generally preferred. They are used in single and proportion; it should perceive the space color or multi-colored groups. But it should without weighing the scale in his mind and be carefull that not to mow grass until feeling uncomfortable (Robinson, 1992; bulbous plants’ leaves turn yellow (Leholm, Kalın, 2004; Bell, 2004; Hansen, 2011; 1998; Evans, 2005). Karaşah and Var, 2012; Alp et al., 2016). For humid conditions, it must be choosen The dominant structure and skeleton in suitable species of bulbous plants to planting design are trees and shrubs, and arrangements at natural and artificial lakes secondly, seasonal flowers and bulbous and ponds (Leholm, 1998; Cornwell, 2004). tubers plants shape the structure. These Species such as Allium, Colchicum, plants are immediately noticed with their Fritillaria, Lilium, Narcissus, Galanthus, vivid colors and abundant flowering and as Muscari, Scilla can be used in arrangements well as remarkable forms. Due to its of rock gardens. Group plantings are dendrological and aesthetic features, preferred in designs (Rees, 1992; Leholm, seasonal flowers and bulbous plants are 1998; Giles and Cornwell, 2004). widely used in urban areas, especially in Bulbous species are suitable for use with flower beds (Kalın, 2004; Bell, 2004; Alp deciduous shrubs and trees, but it is 263 ISPEC Tarım Bilimleri Dergisi E-ISSN:2717-7238 ISPEC Journal of Agr.

Thus, as they can’t get enough light. It can the flowers do not mud with rain or facilitate movement that using them with at irrigation water (Leholm, 1998; Avans, the bottom of the trees around the buildings, 2005). Among the bulbous plants, tulips are on the edges of narrow-leaved trees or mostly used for show and exhibition bushes as combinations (Leholm, 1998; purposes, followed by hyacinths and Sarıbaş, 1999; Giles and Cornwell, 2004). daffodils. These are followed by species In flower beds, informal arrangements with large and showy flowers such as should be preferred instead of formal (De Dahlia, Fritillaria, Lilium, Crocus. They Hertog and Powell, 1999; Giles and can be used with single or small/large Cornwell, 2004; Alp and Aşur, 2006). groups in designs (Leeds, 2001; Evans, They can use in large pots (container) and 2005). according to Gutterman [27], the use of Bulbous plants with pleasant scents and bulbous plants may be preferred where showy flowers may be preferred in green areas are at a minimum level such as fragrance gardens. For example, Narcissus urban areas, squares, airports, bus species have an effective appearance with terminals, railway stations, pier squares. their fragrant flowers. Liliums blossom in Plantations with geophytes in places as summer are one of the indispensable species plazas, hotel gardens, in the office, with their excellent scents (Relf, 1997; shopping centers, home gardens and so on Leeds, 2001).
