Purple Plants
In the colorful kingdom of plants, purple plants are highly favored for their unique elegant temperament. These plants not only add a sense of mystery to gardens but also carry diverse ecological and cultural values. Let's explore the natural code behind purple plants through six typical varieties.
Preferred Varieties for Garden Landscaping
Hyacinth: Sculpture of Spring's Fragrance
This bulbous plant displays a rich purple color through its funnel-shaped corolla and blooms best in a 15-20°C environment. It is recommended to cultivate in loose sandy loam soil, maintaining 6 hours of direct sunlight daily, and requires 10-12 weeks of low-temperature vernalization in winter to bloom normally.
Wisteria: Pollution-resistant Guardian of Summer
With a flowering period of up to three months, it has become the preferred choice for urban greening, and mature plants can tolerate -15°C low temperatures. Trunk pruning can control plant height, and the natural bark peeling creates a unique ornamental effect.
Medicinal Functions and Aromatherapy Value
Platycodon Grandiflorus: Dual Value
The bell-shaped corolla is rich in platycodon saponin, which is commonly used in traditional medicine for expectorant and cough-relieving purposes. When cultivating, it is important to note that day and night temperature differences should reach 8°C or more, and slightly acidic soil with a pH of 6.5-7.0 is most beneficial for root development.
Lavender: King of Aromatherapy
Each hectare of lavender fields can produce 15-20 kilograms of essential oil, with linalool content as high as 35%. It is recommended to use raised ridges to prevent waterlogging, and it is necessary to cut back to 15cm of the main stem after flowering each year to promote branching the following year.
Purple Flower Viola: Pioneer Plant of Early Spring
This perennial herb can germinate within 7 days after the snow melts, and its purple pigment has a protective mechanism for absorbing ultraviolet light. When propagating by division, it is important to retain 3-5 buds, and supplementing with phosphorus and potassium fertilizer in the late autumn can enhance its ability to survive the winter.
Key Points for Maintenance of Special Varieties
Iris species need to ensure that the upper 1/3 of the rhizome is exposed above the soil surface, and cornflower should be sown in spring after vernalization. When cultivating digitalis, it is necessary to practice crop rotation to prevent wilt, with an interval of no less than 3 years.
From garden landscaping to ecological restoration, purple plants show a strong adaptability to the environment. Mastering the light requirements (hyacinth requires full sunlight/purple flower viola tolerant to semi-shade) and soil preferences (sandy loam/clay/slightly acidic) of different varieties can create a rich and layered community of purple plants. It is recommended to combine planting according to regional climatic characteristics to achieve a visual effect of flowers in three seasons and leaves in four seasons.
