Product Details

L. clethroidesis better known as Gooseneck Loosestrife because its slender arching spikes of white flowers have a graceful crook that makes them seem friendly and informal. Bloom is abundant from July into September; the plants in our propagation blocks produce a sea of white spikes every summer. Plants grow to 3′ and are vigorous to the point of invasiveness, which we prefer over plants that limp their way through the season. A superb ground cover in any soil, in full sun or partial shade; it also deserves a role in the border with plants that can help restrain its enthusiasm. Try it with Monarda or Heliopsis. Lysimachia makes a good cut flower and with Amsonia and Platycodon boasts some of the most striking fall color to be had in a perennial garden.

This large genus includes a lot of weedy species, but this exceptionally fine native of China and Japan has been a favorite around here for years.




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.


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.


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.

right plant for the right place!

Lots of people seem to blame the plant for its habit. You've got to place this according to its needs. Yes, it spreads. But it's also a lovely plant. I planted this in the shrub and perennial borders on either side of my front path. So far the new shoots have been easily pulled when they encroach on other plants. Truly, I spend far more time dealing with other "easy" plants than I do dealing with these.

got two starts of this last summer - planted in a north site against the house under short eaves. They have multiplied space x5 and already under the edging to the lawn. They are incredibly tough compared the the hostas that frequently died back in the same area. Beautiful. Need a special space to contain them.

Love this plant

This makes a fabulous perennial, tall groundcover. Use it with good boundaries. Like in a border along a driveway. I use it beneath Limelight hydrangeas and a brick path. They bloom simultaneously, I don't need mulch and the effect is spectacular. I also use it at the end of a driveway at the road where it is bound it by the drive, the road and the lawn. This plant gets a bad rap but go with "right plant, right place" and find a good spot for it.

Love this plant, however it can be invasive

I love this plant. We had it growing in many places on the property we sold.
I do many weddings and this is such a gorgeous addition to the old fashioned/garden flower bouquets andy arrangements. I have found it difficult to find at local nurseries. I ordered three plants from white flower farm, only one came in plantable condition. The other two are struggling to survive. THEY WERE VERY EXPENSIVE AND VERY TINY STARTS.

Latin Name Pronunciation: lye-sim-ak'ee-uh     

A large and attractive group of perennials, some tall, with elegant, arching flower spikes and others of ground-cover stature. They prefer moist soils, where most will spread rapidly from underground stems. Despite this aggressive reputation, many garden species are more restrained, and their long-blooming, showy flowers are an indispensable part of summer borders and bouquets.

Light/Watering: Full sun or part shade. Water thoroughly after planting, and keep a close eye on the plant over the following week. After the first week, give a new plant a good soaking once a week during summer, unless rainfall is plentiful (more than 1" per week). Established plants can generally get by on less water, but most grow best if the soil remains evenly moist. Please note that more is not better. When in doubt, don't water.

Fertilizer/Soil and pH: Not fussy about soil. Although Loosestrife prefers moist, well drained soil, it tolerates poor drainage; it is less vigorous and therefore less invasive in dry 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: Some taller species may require staking. Deadheading after flowers fade helps prevent unwanted seedlings. Divide in spring or fall. Pests are rarely a problem; occasionally rust or leaf spot might occur.
