Grown from seed in living soil without the use of pesticides, chemicals, or carbon fuels.

Ditch stonecrop (Penthorum sedoides) is a native perennial that can be in floodplains, bottom forests, swamps, marshes, muddy shores, prairie swales, and ditches along roadsides across much of the eastern half of the United States.

Flowers resemble those of stonecrop, but this wildflower does not have the succulent leaves typical of plants in the Sedum genus. White flowers are not particularly showy in spring and summer, but the seed capsules do take on beautiful pink and red tones in fall (see images 2-4).

This plant is not commonly encountered in gardens or nurseries, but we think it makes a nice addition to the moist or boggy native plant garden. Fall color is wonderful.

Type: Herbaceous Perennial
Height: 6 to 30 in.
Spread: 12 to 18 in.

We most commonly use the following pot sizes for perennials:

4-inch pot: 3.5" H x 3.5" W x 3.5" D
2-quart pot: 6" H x 5.25" W x 5.25" D
1-gallon pot: 6.87" H x 8" Dia (this is a true one gallon pot, not the smaller 'trade' one gallon pot used by many nurseries)

Check out our illustrated pot size guide here.

Representative trees & shrubs are photographed in their pots and posted on each plant page.

Sustainability

Sustainability is at the heart of what we do at The Old Dairy. We grow all of our plants outdoors without the use of chemicals, fertilizers, carbon fuels, or peat.

Many of our perennials are grown in the ground and dug upon order (this is especially true for larger sizes). This practice allows us to grow stronger, healthier plants using native soil, and ultimately reduces our impact on the environment.

Our open-pollinated seeds are collected from plants in our mother beds, which have never been treated with chemicals or sprays of any kind.
