Chinese Astilbe Astilbe chinensis var. taquetii 'Purpurlanze'

Water

For the Chinese Astilbe 'Purpurlanze', it is important to maintain consistently moist soil, as they thrive in damp conditions. Water these perennials deeply once or twice a week, providing about one inch of water each time, which is approximately half a gallon for a standard-sized plant. During hot or dry periods, increase watering frequency to prevent the soil from drying out, ensuring you're not just wetting the surface but moistening the soil to a good depth. In cooler, wetter climates, you might need to water less frequently. Always check the moisture level of the soil before adding water to avoid overwatering.

Light

Chinese Astilbe 'Purpurlanze' flourishes in partial shade to full shade conditions. They should be positioned in a location that receives filtered sunlight or only morning light, as too much direct sun, especially during the hot afternoon hours, can scorch their leaves. Ideal planting spots include north-facing gardens or under the canopy of deciduous trees where they can receive bright indirect light.

Temperature

Chinese Astilbe 'Purpurlanze' is hardy and can survive in a broad range of temperatures. They can tolerate minimum winter temperatures down to around -30 degrees Fahrenheit. These plants are happiest in cooler conditions, with ideal growing temperatures between 60 to 75 degrees Fahrenheit during the growing season. They may struggle in extreme heat, above 85 degrees Fahrenheit.

Pruning

Pruning Chinese Astilbe 'Purpurlanze' is mainly done to remove spent flower stalks and to tidy up the plant. Prune back dead flower stems after blooming to encourage healthy foliage and possibly a second, smaller flush of flowers. In early spring, as new growth starts, cut away any dead or damaged foliage from the previous year. The best time for major pruning is in the spring before new growth begins in earnest.

Cleaning

As needed

Soil

The Purple Lance Astilbe thrives in moist, well-drained soil rich in organic matter with a soil pH of 6.0 to 7.5. A mix composed of garden soil, peat moss, and perlite or coarse sand would be ideal to ensure proper moisture retention and drainage. Regular addition of compost or well-rotted manure will enrich the soil and support healthy growth.

Repotting

Purple Lance Astilbe should be divided and repotted every 3 to 4 years to rejuvenate the plant and prevent overcrowding. Spring or early fall is the best time to repot, ensuring that the root systems have time to establish before the extremes of summer or winter.

Humidity & Misting

Purple Lance Astilbe prefers high humidity levels, consistent with its native woodland habitats. Aim to maintain about 60-80% humidity around the plant. Although it can tolerate lower humidity, increased humidity can promote vigorous growth and lush foliage.

Suitable locations

• Indoor

  Ensure moist soil, filtered light, and high humidity indoors.

• Outdoor

  Plant in shade, keep soil moist, and mulch to retain moisture.

• Hardiness zone

  4-8 USDA

Life cycle

The life cycle of the Purple Lance (Astilbe chinensis var. taquetii 'Purpurlanze') begins with seed germination in the spring, after a period of stratification which helps to break the seed dormancy. Following germination, the plant develops a basal rosette of leaves and establishes a strong root system. In its second year and subsequent years, the Purple Lance enters a growth phase where feathery plumes of purple flowers bloom atop sturdy stems in mid to late summer, attracting pollinators and adding vibrant color to the garden. After flowering, seeds are produced and dispersed, and the plant enters a period of dormancy in the fall as foliage dies back with the onset of cooler temperatures. Throughout winter, the plant remains dormant, storing energy in its rhizomes underground. With the return of warm weather in spring, the cycle begins anew as new growth emerges from the rhizomes, preparing for another season of flowering.

Propogation

• Propogation time

  Spring to Summer

• The Astilbe chinensis var. taquetii 'Purpurlanze', commonly known as Purple Lance Chinese Astilbe, is typically propagated by division. The best time to divide this plant is in the early spring or late fall when it is not in active growth. To propagate by division, one should carefully dig up the clump of astilbe, ensuring to preserve as much of the root system as possible. The clump should then be gently teased apart into smaller sections, making sure that each section has at least one growth bud. These sections can then be replanted into prepared soil with good moisture retention and shade, as Purple Lance Chinese Astilbe thrives in these conditions. The soil should be kept evenly moist especially during the first growing season to ensure the divisions establish well.
