ALSTROEMERIA sp. Indian Summer

Description and Characteristics

Alstroemeria 'Indian Summer' is a stunning, mid-sized Peruvian lily hybrid known for its fiery orange and golden-yellow flowers that contrast beautifully with its deep bronze-purple foliage. It is part of the Summer Paradise® Series, which is bred for improved hardiness, long flowering, and outstanding garden performance.

This cultivar reaches a height of approximately 60–90 cm and spreads 45–60 cm, forming a robust clump of upright stems and lush foliage. From late spring through to the first autumn frosts, 'Indian Summer' puts on a spectacular display of trumpet-shaped blooms, each streaked with dark markings in the centre, creating a tropical yet elegant look.

Not only is it an excellent choice for beds and borders, but it is also a top-tier cut flower, with long-lasting blooms that can hold in a vase for up to two weeks. Its vivid tones and architectural foliage also make it ideal for showy mixed containers.

• Striking orange-yellow flowers with burgundy flecks

• Rich, dark bronze-purple foliage adds year-round contrast

• Upright, clump-forming habit ideal for borders and large containers

• Long flowering season: May to October

• Excellent for pollinators and floristry

• Hardy to approx. -10°C (USDA Zones 7–10) with mulch in winter

Growing Conditions and Maintenance

‘Indian Summer’ thrives in a sunny, sheltered location with well-drained soil and regular moisture. It is low maintenance once established and performs reliably in a range of garden settings.

• Sunlight Requirements:

  • Prefers full sun for best flowering and foliage colour

  • Tolerates light afternoon shade, especially in hot regions

• Soil Preferences:

  • Requires well-drained, fertile soil

  • Avoid heavy clay or consistently wet ground

  • Neutral to slightly acidic pH is preferred

• Watering Needs:

  • Water regularly during dry periods to maintain even moisture

  • Do not allow the soil to dry out completely, especially in containers

  • Avoid waterlogging, particularly in winter

• Fertilising:

  • Feed with a balanced, slow-release fertiliser in early spring

  • Optional: use a liquid bloom feed every 2–4 weeks during the flowering season

• Deadheading and Pruning:

  • Pull spent stems from the base rather than cutting to encourage regrowth

  • Remove yellowing leaves and faded blooms to keep the plant tidy

  • Cut back in late autumn after foliage dies down naturally

• Winter Protection:

  • In Zones 7–8, apply a thick mulch layer in late autumn to insulate the root zone

  • In colder areas, lift and store tubers in dry compost in a frost-free location

  • Containers can be moved to a sheltered, frost-free area or insulated with fleece
