Dahlia pinnata
Más nevek: Garden Dahlia, Mexican Dahlia
Dahlia is a colorful and diverse perennial plant that blooms from summer to autumn. It is popular in gardens due to its wide range of flower shapes and colors.
Basic info
Dahlia (Dahlia pinnata) belongs to the Asteraceae family and originates from Mexico and Central America. It is a tuberous perennial plant that survives winter by storing nutrients in its tubers. The plant has a bushy growth habit and varies in height from 40 to 150 cm. Its flowers come in many forms, including single, double, pompon, and cactus shapes, with colors ranging from white to deep burgundy.
The blooming period lasts from June to October, providing long-lasting garden color. Dahlias prefer well-drained, nutrient-rich soil and full sun exposure. They are not frost-hardy, so tubers must be dug up in autumn and stored in a cool, dry place to avoid freezing.
Care requires moderate maintenance, including regular watering, fertilization, and deadheading to promote continuous flowering. Propagation is usually done by dividing tubers or sowing seeds in spring.

Care
Dahlias require a sunny location and nutrient-rich, well-drained soil. Water regularly but avoid waterlogging to protect the tubers. Fertilize during the growing season to encourage abundant flowering. Remove faded flowers to stimulate new blooms. In autumn, dig up tubers, clean them, and store in a cool, dry place until next spring.
Propagation
Propagation is mainly by dividing tubers in spring. Tubers are separated and planted, or seeds can be sown, though seed-grown plants may not retain parent traits. Cuttings are started in a warm, bright place and transplanted outdoors when strong enough.
Diseases & pests
Dahlias can be susceptible to fungal diseases such as powdery mildew and gray mold, especially in humid conditions. Aphids and mites are common pests. Good air circulation and removal of infected parts help maintain plant health.

Dahlias are non-toxic to humans, dogs, and cats, making them safe for family gardens. Allergic reactions are rare but possible in sensitive individuals.
Ecology
Dahlia flowers attract bees, butterflies, and other pollinators, playing an important role in garden ecology. They are not invasive and do not spread aggressively in natural habitats.
Usage
Dahlias are primarily ornamental plants used in gardens, parks, and balconies. Their flowers are also popular in floral arrangements and decorations. Their wide variety of colors and forms make them favorites in landscape design.
