Product Details

Product Details

A star of the late-season garden, Sanguisorba officinalis produces airy constellations of wine-colored, bottlebrush flower heads that sway atop slender stems, adding movement, texture, and a rich tone to the summer and autumn border. Pair this Great Burnet with Ornamental grasses, Asters, Symphotrichums, Black-eyed Susans, and other fall garden favorites. For the balance of the season, this rhizomatous perennial produces a dense cushion of pinnate, serrated green foliage that provides texture, support (for neighboring plants), and interest.

Sanguisorba is a genus in the Rosaceae family containing about 18 species, which have been used to create thousands of hybrids. Used primarily for its long season of bloom and late season color in the garden, young leaves can also be used in salads and soups. Plants are deer-resistant and thrive in full sun and moist, well-drained soil.

HOW PLANTS ARE SHIPPED

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

WHEN WE SHIP

We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.

OUR GUARANTEE

We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Eaten by a squirrel within 24 hours of planting

A viewer from Richmond, VA

Arrived in good shape, I planted it out in a pot on our deck, but it was eaten in its entirety by a squirrel within a day of planting. So frustrating. This is not White Flower Farm's fault, but it would be great if they could include in the planting instructions or the description if a plant is particularly appetizing to critters. I have never had this happen, so didn't think it needed to be fully protected after planting.

TALL baby 6 ft

A viewer from Greensburg PA

This lovely plant did NOT top out at 4 ft as it did in Year 1 . Now in Year 2 and its 6 ft so far and its only July 29. I love it but am going to have to find a new spot in the garden....looks like the Empire State Building where it is now. But really pretty thing.

Latin Name Pronunciation: san-guih-sor'-bah

Spires of loose, bottlebrush flowers nodding on fine, wiry stems above neat mounds of crimped, narrow foliage decorate the late summer garden. Burnets are happiest in a sunny spot where the soil stays moist and, when not in bloom, their leaves add textural interest.

Light/Watering: Full sun or partial shade. Water thoroughly after planting. After the first week, give a new plant a good soaking once a week during summer, unless rainfall is plentiful (more than 1in per week). Established plants can generally get by on less water, but Sanguisorba does best if the soil remains evenly moist.

Fertilizer/Soil and pH: Moist, well drained soil. We recommend against fertilizing at planting time and during the first growing season in your garden. Plants need time to settle in before being pushed to grow. Most established plants grow best if fertilized with a light hand. We fertilize perennials just once -- in early spring -- with a light but even coverage of a balanced, granular fertilizer (such 10-10-10 or an organic fertilizer). If a concentrated, water-soluble fertilizer is used, please follow the manufacturers' recommendations carefully.

Continuing Care: Cut back foliage after blooming if it looks tired. Burnet forms dense, running clumps, and can be divided in early spring.
