Silver Thistle is a large flowering biennial that makes an excellent cut flower. It will grow happily in the poorest of soils.

Fun Fact: the straw yellow flowers open in dry weather and close in moist weather. Flowers retain this property for a long time even after they are cut. Silver Thistle was initially called 'Weather Thistle' as flowers were often nailed over cottage doors to indicate when rain was coming.

Ordering information

Preorders

You may place your order anytime to reserve plants for spring 2025 shipment. If you place multiple orders, we will combine plants into one box (or as many as needed) and any extra shipping charges will be refunded when we ship.

We will begin shipping plants as soon as plants begin to emerge from dormancy in spring. Woodies will likely begin shipping in April. Perennials will likely begin shipping in May. If ordering multiple varieties, we will hold until all plants are ready to ship together. If you would like to receive plants sooner please reach out.

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.

Live plants ship in spring and fall only. Plants may ship dormant, depending on variety and season. Shipping costs are most reasonable when bundling like size plants.

  • 4-inch: 1-6 plants ship for $15.00 / 7-13 plants ship for $18.00 / 14-30 plants ship for $40.00
  • 1-gal: 1-2 plants ship for $18.00 / 3-4 plants ship for $25.00 / 5-6 plants ship for $40.00

Nursery pick up

Plants can be collected from the nursery Monday through Sunday from 10am-4pm in Spring, Summer, and Fall. We prefer 24 hour notice to get your order together and will email you when ready for collection.

If you place a SPRING 2025 PREORDER, we will contact you in spring when your plants are ready for collection. Woodies will likely become available for collection in April. Perennials will likely become available in May. If ordering multiple varieties, we will hold until all plants are ready to be collected together.

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.

Germination information

Sowing Instructions

This plant is easy to grow from seed. Sow thinly on a high quality seed starting mix and cover lightly. Seeds should be kept consistently moist, though not wet. Please do not use a humidity dome. Bottom watering is best. Warm temperatures of around 68°F will yield best results. Seedlings benefit from cooler temperatures after germination.

Timing Options

Fall · Outdoors · We prefer to grow according to the natural rhythms of the season. We sow most of our seed in late summer or fall. They germinate in warm daytime temperatures, sleep through winter, then reemerge in spring.


Spring · Outdoors · 
Seed can be started outdoors when temperatures warm in spring. Wait until daytime temperatures are consistently in the mid to high 60s.


Late Winter · Indoors · 
Seed can be started indoors under lights 6-8 weeks before your last frost date. Plants may germinate faster this way, but they will be less robust. We strongly recommend sowing outdoors according to the natural rhythms of the season
