Alstroemeria ‘Inca Tirol’

Alstroemeria ‘Inca Tirol’: A Jewel of the Garden

Alstroemeria ‘Inca Tirol’, commonly known as Peruvian Lily, belongs to the Alstroemeriaceae family. This family is well-known for its vibrant and long-lasting flowers, often used in floral arrangements. Native to South America, Alstroemeria species, including hybrids like ‘Inca Tirol’, have been cultivated and appreciated for their exotic, lily-like blooms and robust growth habits. The name Alstroemeria honors the Swedish botanist Clas Alstroemer, a contemporary of Carl Linnaeus, who brought these plants to Europe in the 18th century.

Description

Alstroemeria ‘Inca Tirol’ is a compact, mounded herbaceous perennial that reaches a height of 20-30 cm (8-12 inches) and spreads 20-30 cm (8-12 inches). The plant is characterized by its creamy white flowers, accented with blush pink and pale yellow streaks, and darker speckles at the center. These exquisite flowers appear in abundance from early spring through to autumn, providing continuous color in the garden. The blooms, measuring 5-7 cm across, are perfect for cutting and adding to floral arrangements.

Care Instructions for Alstroemeria ‘Inca Tirol’:

Light Requirements:

• Sun Exposure: Full sun to light shade. While the plant tolerates light shade, it blooms best when exposed to full sun.

Soil and Watering:

• Soil: Prefers well-drained, humus-rich soil. Avoid waterlogged conditions, which can cause root rot.
• Watering: Water regularly to keep the soil moist during the active growing season. Once established, Alstroemeria ‘Inca Tirol’ is relatively drought-tolerant due to its fleshy root system, which stores moisture.

Temperature and Hardiness:

• Climate: Thrives in cool to subtropical climates.
• Frost Tolerance: Hardy and can survive winter outdoors once well-established. Protect young plants with mulch to insulate the roots in colder regions.

Maintenance:

• Pruning: Cut back hard after flowering to encourage new growth and more blooms. During the growing season, remove spent flower stems to promote further blooming and maintain plant health.
• Fertilization: Apply a slow-release fertilizer in late winter and spring. Alternatively, use a liquid fertilizer regularly during the flowering period to support the plant’s vigorous growth and abundant blooming.

Propagation

Propagation Methods:

• Division: The most reliable method is by dividing mature clumps in spring or autumn. Carefully lift and separate the plants, ensuring minimal damage to the fragile roots. Replant the divisions immediately.
• Seed Propagation: Alstroemerias can be grown from seed, but this method is less common due to the variability in the resulting plants and the time required to reach flowering size. Sow seeds in autumn, following a period of cold stratification to improve germination rates.

Steps for Division:

1. Timing: Best done in spring or autumn when the soil is warm and damp.
2. Lifting: Gently dig up the plant, taking care not to damage the roots.
3. Separating: Divide the root clump into smaller sections, ensuring each section has several shoots and a good portion of roots.
4. Replanting: Plant the divisions immediately in prepared soil, keeping the same soil level as before. Water well to help the plants settle in.

Steps for Seed Propagation:

1. Seed Collection: Collect seeds in autumn once the seed pods turn brown and start to split. Store the seeds in a paper bag until sowing.
2. Sowing: Sow seeds in 8 cm (3-inch) pots filled with seed compost. Cover with a thin layer of vermiculite.
3. Stratification: Maintain at 20°C (68°F) for three weeks, then move to a cold frame or greenhouse at 5°C (40°F) for another three weeks.
4. Germination: Return to 20°C (68°F) for germination. This process can be erratic, so patience is required.
5. Potting On: Once seedlings appear, keep them in clumps and pot on carefully.

Uses and Design Ideas

Alstroemeria ‘Inca Tirol’ is a versatile plant suitable for various garden settings:

• Garden Beds: Its compact size and continuous blooms make it ideal for borders and flower beds.
