Flowering period

In central North Carolina, the heaviest flowering occurs in May with flushes of flowers occurring throughout the summer and into fall.

How to grow

Grow Swamp Leather Flower in sun to part shade. Like most clematis, the root zone benefits from some shade. Prefers evenly moist soil, but is very adaptable and can tolerate flooding and periodic drought.

Care and maintenance

Flowers form on new growth and the old stems can be cut to the ground anytime through winter. Water during extended droughts in drier sites.

Pine voles can be a problem eating the crowns of Clematis. To protect plants, create a cylinder with hardware cloth (½ inch or smaller mesh) and plant the Clematis inside it. Make sure the hardware cloth is buried at least 6 inches deep to protect it from burrowing voles.

Where to plant

Small arbors, trellises, and step railings where its fragrant flowers can be appreciated. For larger arbors and fences, consider planting a more vigorous vine-like crossvine or coral honeysuckle.

When to plant

It can be planted anytime the ground is not frozen in Southern gardens. Keep plants well-watered if planting in the summer.


Plants can be planted 3 to 4 feet apart.

When will my plant flower?

When will my order be shipped?

All plants are shipped within two weeks of placing an order.

Is it okay to plant in the winter?

Yes, as long as the soil is not frozen. Planting native perennials in winter and early spring gives your plants a head start before the summer heat arrives.

What if it’s too cold to plant where I live, but I want to buy a plant before it sells out?

Dormant plants can safely be kept in a basement, garage, or cool room until you are ready to plant in late winter or early spring.

How will my plants get delivered?

Most orders are shipped on Monday or Tuesday via UPS Ground, which depending on the destination takes between 1 to 4 days.
