Arisaema heterophyllum Seeds | Chinese Jack-in-the-pulpit
LATIN NAME: Arisaema heterophyllum
COMMON NAME: Chinese Jack-in-the-Pulpit
Plant Profile
Chinese Jack-in-the-Pulpit (Arisaema heterophyllum) is a distinctive species. The blooms are worked steadily by bees for as long as they are open. Each of these traits is modest on its own; together they make a garden-worthy plant.
Science & Biotechnology
Within the Arisaema group, Arisaema heterophyllum is of continuing interest to researchers working on plant diversity, seed biology and the selection of improved garden forms. This significant processing requirement has made species a notable subject in research on traditional Chinese medicine safety and quality control standards. For practical purposes the message is encouraging: generations of cultivation have produced plants of predictable, well-mannered garden character.
Uses & Benefits
Chinese Jack-in-the-Pulpit brings genuine presence to the garden and earns its keep across the growing season. As an ornamental woodland plant, its unusual hooded flower structure and divided foliage give it genuine curiosity value in shaded native plant gardens, admired for its form rather than handled or used medicinally by home gardeners. Given the right start, it carries on with minimal intervention.
Jack-in-the-pulpit rhizomes are used in Chinese medicine only after processing, as Zhi Tian Nan Xing, for phlegm conditions. Raw rhizomes are intensely irritating due to calcium oxalate needles and alkaloids, and must never be used fresh.
Growing from Seed
Sow fresh seed of Chinese Jack-in-the-Pulpit under ordinary good conditions. A period of cold, moist stratification helps seed germinate evenly, after which it should be sown into a loose, humus-rich, well-drained mix. Use a loose, well-drained seed compost, sow evenly over the surface and cover lightly, and keep everything evenly moist in bright light. Shift the seedlings into small pots as soon as they can be handled, and give them bright light until planting-out time.
Our Take
Once established, Chinese Jack-in-the-Pulpit largely looks after itself. The traditional uses covered above are what first made this species worth cultivating. Fresh seed sown into evenly moist compost is most of the battle won.
