Codonopsis pilosula (Codonopsis) 9 cm Pot

Growth habit & appearance: Codonopsis pilosula produces slender, twining stems that climb or trail with ease, clothed in delicate, oval leaves of soft mid-green. In summer, it bears charming bell-like flowers, typically pale green or creamy with subtle veining that creates a lantern-like effect. Beneath the soil, the plant forms fleshy, tapering roots that have been historically prized in traditional herbal practice. Its light, airy habit makes it ideal for trellises, obelisks, or informal woodland edges.

Growing conditions: A hardy perennial native to Asia, Codonopsis adapts well to Irish conditions when planted in fertile, moisture-retentive but well-drained soil. It tolerates full sun to partial shade, though light shade often produces greener, more vigorous foliage. Sheltered sites prevent wind damage to the delicate stems, and consistent moisture during dry spells supports strong growth. Provide a support structure for its natural climbing habit.

Traditional & herbal uses: In Asian traditional practice, Codonopsis has long been associated with supporting energy, addressing fatigue, encouraging appetite, and promoting general vitality. It has also featured historically in uses relating to lactation and circulatory balance, reflecting its broad role as a gentle tonifying herb.

Maintenance & harvesting: Keep the base of the plant weed-free, as young shoots are easily overshadowed. Tie in new stems as they develop, guiding them onto supports to prevent tangling or breakage. Water during prolonged dry periods and mulch annually to preserve soil moisture. Roots are typically harvested from well-established plants at 3–4 years of age, lifting them carefully to avoid snapping the soft, fleshy taproots. Remove spent growth in late autumn as the plant dies back naturally. Keep an eye out for slugs in spring! They love the new growing shoots..
