When should I plant Jack-in-the-pulpit?

Answered by Tom Adger

When it comes to planting Jack-in-the-pulpit, there are a few different methods you can use depending on whether you have container grown plants, corms, or seeds. Let’s explore each of these options in detail.

If you have container grown Jack-in-the-pulpit plants, it is best to plant them in the spring. This allows them to establish their roots and adjust to their new environment before the heat of summer arrives. When planting, make sure to choose a location that receives partial to full shade, as these plants prefer shady conditions.

On the other hand, if you have corms, which are the bulb-like structures from which Jack-in-the-pulpit plants grow, you can plant them in the fall. Dig a hole that is about 6 inches (15 cm.) deep and place the corm in the hole with the pointed end facing upwards. Cover the corm with soil, water well, and then let nature take its course. By planting in the fall, the corms have a chance to establish their roots throughout the winter and will be ready to sprout in the spring.

If you prefer to grow Jack-in-the-pulpit from seeds, you can collect ripe berries from existing plants in the fall and plant the seeds in the spring. To collect the berries, wait until they have turned a bright red color and are fully ripe. Gently squeeze the berries to remove the seeds, being careful not to damage them.

In the spring, prepare a well-draining potting mix and sow the seeds on the surface of the soil. Do not bury the seeds, as they require light to germinate. Keep the soil consistently moist, but not waterlogged, and place the pot in a shady location. It’s important to note that plants grown from seeds take longer to mature and come to flower. In fact, it may take three or more years for them to reach flowering stage.

The timing for planting Jack-in-the-pulpit depends on the method you choose. For container grown plants, spring is the best time. For corms, fall planting allows them to establish roots before sprouting in spring. And if you’re starting from seeds, collect ripe berries in fall and sow them in spring, but be prepared for a longer wait until flowering. Happy planting!
