Persian Stonecress is a beautiful subshrub with glaucous evergreen foliage that is dusted in a fine white powder. Fragrant light pink to lilac flowers cover the compact mound from spring to summer. Flowers are followed by unusual papery seed pods that provide interest through fall and winter.
Growing Note: This plant does best in the west, however, it can be grown successfully in the Northeast as long as it is provided with excellent drainage. Best in a rock garden or alpine garden. Plant in spring or early summer. It needs a long, warm growing season to establish a healthy root system before the cold and wet sets in.

Our plants overwinter outdoors where they follow the natural rhythms of the season. We never force our plants to break dormancy early. Admittedly, early-leaf-out is customer pleasing, but it is bad practice both for the long-term health of the plant and for the environment.
Plants shipped in early spring will very likely not be in full leaf. We grow in a cold area (zone 5), which means that customers in warmer climates will likely receive plants behind their own garden schedule. Not to worry though, healthy plants catch up quickly.

We will resume shipping plants as soon as plants are ready and temperatures are appropriate in our location and yours.
We will check in with you a week before shipping to make sure you receive your plants at a time that is convenient for you.

Nursery pick up
We will email you to schedule a day and time to collect your plants when they are ready in spring. Generally, plants can be collected from the nursery Monday through Sunday from 10am-4pm in Spring, Summer, and Fall.
Plant Sizes
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.
