You can choose some flowers and trees with auspicious meanings, such as pomegranate (a hundred children and a thousand grandchildren), osmanthus fragrans, magnolia grandiflora (jade hall is rich), bamboo (high wind and bright festival), wisteria with scaffolding, radix aucklandiae, rose, lingxiao, honeysuckle (suitable for activities of the elderly), plantain, camellia, gardenia, colorful red maple and so on. In short, we should consider the psychology of the elderly, seasonal changes and safety (some flowers and plants that are easy to harm the elderly, such as prickly cactus, are toxic and should not be selected). The most important thing is to conform to the garden design style. These flowers and trees are more suitable for classical gardens in China.
