Cape plumbago (Plumbago auriculata) is a tender evergreen shrub with a mounding habit and lovely blue flowers. Where it is fully hardy, this plant blooms nearly year-round.

Easy to grow in fertile, moist but well-drained soil in full sun or part shade. Cape plumbago is a great candidate for containers that can be overwintered and reused each year - an eco-friendly alternative to annuals. Check out this page from Missouri Botanical Garden for overwintering tips.

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.

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.
