The way to Plant, Develop and Care For Twinleaf Flowers

The delicate white flowers of twinleaf, or Jeffersonia diphylla, are a beautiful sight alongside other early-season plants such as bloodroot and spring beauties. This uncommon native wildflower is a little-known plant that grows in moist, shaded woodlands scattered throughout eastern North America.

Twinleaf is a welcome addition to a shaded woodland garden in the home landscape. It grows best in partial to full shade with rich, medium-moisture, well-drained soil. Although rare in the wild, it is not difficult to grow in a garden setting. As long as you live in a fairly mild temperate climate and have compatible growing conditions, you should have no problems growing your twinleaf plants. 

Twinleaf is perhaps most appreciated for its white spring-blooming flowers. The flowers are showy and attract early-season pollinators. The flowers are simple, pure white, and have 8 petals. After flowering, plants develop an unusual seed capsule resembling an oval-shaped hooded pod. This seed capsule pops open when the seeds are fully ripe, shooting the seeds a short distance away from the parent plant and allowing the colonies to expand.

While not flowering, twinleaf has attractive foliage from spring through fall. Multiple stems emerge from the ground, each with a single leaf divided into equal halves and separated by a thin connector. The leaves reach only about 6 to 8 inches high in the spring. After flowering, the leaves and stems continue to grow, eventually reaching a peak height of around 12-18 inches tall.

Plant History

A close-up of a delicate twinleaf flower reveals its exquisite beauty. Its petals are a soft shade of white. The vibrant leaves in the background enhance the flower's allure, providing a vivid backdrop of lush greenery.Other spring wildflowers are more well-known compared to twinleaf, as it is a relatively uncommon flower.

Twinleaf is a spring-blooming wildflower that is native to eastern North America. Only one species of twinleaf (Jeffersonia diphylla) grows in North America. Another species (J. dubia) is native to Asia. There are no known cultivars of this wild plant. 

Within its range in North America, twinleaf grows in moist woodlands alongside other familiar spring-blooming flowers such as spring beauty, bloodroot, trillium, wild ginger, and Solomon’s seal. It blooms from March to May with showy white flowers.

Unlike the spring ephemeral wildflowers that go dormant shortly after blooming, twinleaf foliage remains green throughout the growing season.

This plant is somewhat uncommon and not as well-known as other spring wildflowers. It is considered a rare or threatened species in some parts of its range.

It can, however, be grown by the home gardener for an attractive addition to the home landscape, as long as you can legally obtain seeds or plant starts from a reputable source. Never dig these plants from the wild.

It does not grow as a creeping or vining plant but forms a dense leafy cover.

For the adventurous home gardener, twinleaf is easy to grow and low maintenance.  If you live in USDA plant hardiness zones 5 through 7, you should be able to grow twinleaf in a moist woodland garden setting. 

This plant is relatively low-growing and makes an effective ground cover. It does not creep or vine along the ground. Instead, it will create a dense leafy foliage cover for smaller areas.

In ideal conditions, it will multiply and spread over time, creating a fairly dense cluster of leafy vegetation. Divide these plants, if needed, in the fall. Division is unnecessary if you want to grow large colonies of twinleaf.

Twinleaf would be perfectly at home in a moist wooded area under some trees. Give it a location with partial to full shade. If you are growing under deciduous trees, plants will receive more sunlight in the early spring before the trees leaf out, and then, by the time the weather has warmed, they will be protected from bright direct sunlight by the leafy canopy. 

To keep these plants looking their best, use some mulch around the base to keep the roots cool and moist and help prevent them from drying out. Be sure to grow them in moist, well-drained soil. Twinleaf is not drought-tolerant, preferring its soil to stay consistently moist but not saturated.


Twinleaf can be propagated and grown from seed or by dividing mature clumps. The easiest way to acquire a new plant would be to obtain one from a gardening friend. If your gardening friends have never heard of this species, your next best option would be to buy a nursery-grown plant from a reputable online grower specializing in native plants. This native can be grown from fresh seeds, but it can be difficult to obtain them unless you already have a source of mature plants.

Surrounded by a rich layer of mulch, the ground provides a nourishing bed for the purple twinleaf flowers.Fresh seeds are essential for the successful growth of twinleaf, which can be easily cultivated from seed.

Twinleaf is easily grown from seed, but only if the seeds are fresh. Seeds should be recently harvested and sown as soon as possible before they can dry out, as the germination rates drop quickly after harvest. It should be noted that plants grown from seed will take a long time to reach flowering maturity, between 3 and 5 years.

If you can access flowering plants, you can collect your own seeds. The trick, however, is collecting them before the pods pop open, as the force with which the pods pop open will distribute the seeds away from the plant. After flowering, keep a close eye on the seed pods. Watch for the seed pods to turn brown. At this point, the seeds should be viable and ready to harvest. 

If you can obtain freshly-harvested seeds, put them in moist soil in an airtight bag and store them in the refrigerator to keep them fresh. In the fall, winter, or very early spring, sow the seeds outside:

  1. Place the seeds on the soil surface.
  2. Gently push them in slightly without burying them under the soil.
  3. Cover the seeds with a very thin layer of mulch and keep this area moist.
  4. After the winter cold stratification in your refrigerator, your seeds should sprout in the spring.

You are unlikely to find twinleaf plants for sale at your local commercial garden center. Your best source of buying young plants will be through a specialty nursery that stocks nursery-grown native plants. Some botanical gardens, arboretums, or gardening clubs may sell native plants, or you can look for online sellers specializing in native species.

Timing is important for planting your seedlings into their final garden location. You will want to transplant your seedlings on a cool spring day into a pre-prepared moist, shaded location. Twinleaf seedlings can be quite delicate, so handle them with extreme care to avoid damaging them.
