Description

Impatiens Holstii 'Mix' is a particularly floriferous and well-branched annual, ideal for shaded areas of the garden. This mix offers a wide range of attractive colours, perfect for brightening up borders, flower beds, or planters. It easily adapts to different types of landscaping. Sow between March and May, either under cover or directly in the ground. Depending on the sowing period, Impatiens will flower from mid-June onwards.

Impatiens holstii, also known as Impatiens walleriana, belongs to the Balsaminaceae family. Native to the tropical regions of East Africa, particularly Kenya and Tanzania, this species has spread worldwide due to its popularity in gardens. This selection grows quickly and is cultivated as an annual in our climate. Each plant develops from a thick stem into an upright clump with sturdy stems, a bushy and spreading habit, reaching 20 to 30 cm in height and about 30 cm in diameter.

The flowers of Impatiens Holstii 'Mix' are the main attraction of each plant. They display a vibrant and varied colour palette, including shades of red, salmon pink to fuchsia pink, and white. The flowering period extends from June until the first frosts. The relatively small but very abundant flowers form a dense floral carpet that almost entirely covers the foliage. The leaves, meanwhile, are deep green, ovate, and slightly toothed, providing a beautiful backdrop for the bright flower colours. The growth of this variety is rapid, allowing it to quickly fill empty spaces in flower beds or planters.

Impatiens Holstii 'Mix' works well in flower beds and borders or large flowering borders. It is also a plant with few rivals for enlivening partially shaded areas of the garden, much like begonias. In summer compositions, mix your impatiens with annual lobelias, garden primroses, and heucheras.

Tip: To maintain adequate water and preserve soil moisture, it is beneficial to apply mulch around the base of the plants.

Planting and care

To successfully sow Impatiens Holstii Mix, start by sowing the seeds indoors approximately 8 to 10 weeks before the last frost. Use a light, well-draining potting mix, preferably enriched with organic matter. The seeds should simply be pressed onto the surface of the soil, as they require light to germinate. Maintain a consistent temperature of around 20 to 24°C and ensure the substrate remains moist but not waterlogged. Germination should occur within 14 to 21 days. Once the seedlings are sufficiently developed, transplant them into individual pots, gradually acclimatising them to outdoor conditions. Wait until all risk of frost has completely passed before planting them in the ground or in containers, spaced 15-20 cm apart.

Impatiens is easy to grow. To accelerate its growth, grow it on in a pot in a warm and bright location. Plant Impatiens in moist, well-drained soil rich in humus. Water regularly, but avoid overwatering. Apply a liquid fertiliser for containers once or twice a week during the growth period. Remove faded flowers and dry leaves as needed to maintain a neat appearance and prolong flowering. Be mindful to protect it from slugs, which are fond of its young leaves. Lastly, although resistant to mildew, it is important to monitor for signs of disease or pests and take prompt action if necessary.
