Because of their ecological, aesthetic, and beneficial characteristics, native desert plants are highly significant. They can also be utilized in landscape architecture, particularly in environments with harsh conditions. The present study aims to evaluate the potential utilization of the wild desert plants Pancratium maritimum L. (Amaryllidaceae) and Artemisia herba-alba Asso (Asteraceae) in sustainable landscape architecture strategies.
Pot experiments were conducted, including different water regimes and soil types. In the case of P. maritimum, all growth parameters showed significant differences (P˂ 0.001) among the water regime treatments, except ground cover. The same trend was notable between the two soil types, except for leaf area and maximum leaf length. Results recommended irrigating P. maritimum to 75% of field capacity when reached 30% in sandy soil (W2S5) due to its comparatively low water consumption (70 ± 12 L/ month/ m) and relatively minimal effort, while maintaining the plant's aesthetic value showing considerable values of growth parameters and being not significantly different from highest emmeans for each studied growth parameters. In the experiment of A. herba-alba, all growth parameters showed significant differences (P˂ 0.001) among the water regime treatments, with notable significant variations between the two soil types in all growth parameters. The results recommended irrigating A. herba-alba to 75% of field capacity when 35% is reached in its native soil (W2S2), as it shows the highest emmean value for all studied growth parameters. According to our findings, P. maritimum was successfully propagated by bulb, resulting in a 100% success rate. A. herba-alba demonstrated successful vegetative propagation by stem cuttings; both herbaceous and semi-woody, retaining its attractive appearance. Herbaceous cuttings of A. herba-alba are more successful in propagation, especially when using sandy soil in spring.
P. maritimum and A. herba-alba had effective strategies to mitigate the adverse effects of drought stress. The present preliminary investigation's findings may substantially improve water valorization by using native plants in landscaping, especially in arid and semi-arid regions.
由于其生态、美学和有益特性，原生沙漠植物具有高度重要性。它们还可用于景观设计，特别是在条件恶劣的环境中。本研究旨在评估野生沙漠植物海滨水仙（石蒜科）和白蒿（菊科）在可持续景观设计策略中的潜在利用价值。
进行了盆栽试验，包括不同的水分条件和土壤类型。对于海滨水仙，除地被覆盖外，所有生长参数在水分条件处理之间均表现出显著差异（P˂0.001）。在两种土壤类型之间也有相同趋势，除叶面积和最大叶长外。结果建议，由于海滨水仙耗水量相对较低（70±12升/月/平方米）且养护相对省力，在沙质土壤（W2S5）中，当土壤湿度达到30%时，将海滨水仙灌溉至田间持水量的75%，同时保持植物的美学价值，其生长参数表现出相当的值，且与各研究生长参数的最高最小二乘均值无显著差异。在白蒿的试验中，所有生长参数在水分条件处理之间均表现出显著差异（P˂0.001），所有生长参数在两种土壤类型之间也存在显著差异。结果建议，在白蒿原生土壤（W2S2）湿度达到35%时，将其灌溉至田间持水量的75%，因为它在所有研究生长参数中表现出最高的最小二乘均值。根据我们的研究结果，海滨水仙通过鳞茎成功繁殖，成功率达100%。白蒿通过茎插条实现了成功的营养繁殖；包括草本和半木质插条，均保持其美观外观。白蒿的草本插条繁殖更成功，尤其是在春季使用沙质土壤时。
海滨水仙和白蒿具有减轻干旱胁迫不利影响的有效策略。本初步调查结果可能通过在景观美化中使用原生植物，特别是在干旱和半干旱地区，大幅提高水资源利用效率。
