Gardeners' Notes:

This plant bloomed the spring after its fall planting. It then survived a brutal Texas summer of no rain receiving no rain for months and only 2 or three supplemental watering during the summer. It is planted in a limestone gravely soil that was amended with granite sand and compost. I thought it had dried to a crisp after its glorious flowering , but it greened up after the November rains and has grown larger and made many bloomstalks this spring. I LOVE IT against my artemisia "Valery Finnis" and Palaver rhoeas.I am planting more. I have some Standing cypress behind it reiterating its tall form in red. Very nice. Easy to grow from seed. I am now experimenting with it in different soils like a more moist rich average garden soil and a full sun scree.

This species is not to be confused with either the widely invasive purple loosestrife or the thuggish gooseneck loosestrife.

Burgundy loosestrife is a plant of quiet beauty with beautiful silvery bluish foliage and a very long season of bloom.

The leaves have a silver stripe down the middle, and a subtle silvery tone over all.

The flowers are not purple but a very deep burgundy red that's almost black. Bloom proceeds on the flower spikes from the bottom upwards, and the spikes continue to lengthen and produce new buds at the tip for month after month. No deadheading is necessary. If you cut the flower spike at the base, multiple secondary spikes will form.

Prefers full sun and well drained soil. It is reasonably drought tolerant... read more

Absolutely love this plant! What a beautiful plant she is. I am in love with the silvery bluish leaves and the spikes of flowers? WOW! They are just gorgeous. I seem to be the only person around this part of Montana ( maybe all of Montana? ) that grows this and/or knows what it is. Mine has stayed right where I planted it and it is in full bloom as we type and has been for sometime now. I purchased my plant from Annie's Annuals in Richmond, California via mail order along with a number of other plants. They have all done splendidly well and this one is all I hoped for and more. I was attracted by the photo and description of the plants leaves, growth habit and especially those fabulously beautiful reddish purple flowers that grow like Gooseneck Loosetrife or Looseneck Goosetrife as I like ... read more

We've grown Lysimachia atropurpurea 'Beaujolais' for two years. Last year we planted it in full sun in heavy, sticky clay soil - it succumbed in the summer heat. This year we planted it in several spots with different light conditions (full sun to light shade) in much better soil and so far it seems to be thriving. It does, however, appear to be a finicky plant - not too wet, not too dry, but we still love the burgundy flowers and the gray-green foliage and are hoping for success this year. This is NOT an invasive species and should not be confused with the invasive tendencies of the other species in this genus. At summer's end we'll report how the plant survived the hot summer heat of Virginia . Hopefully we'll be able to replace the neutral rating with a positive!

I'm giving this burgundy-colored "Gooseneck Loosestrife" a neutral rating because I just added it this year, but I was drawn to those interesting hooked flowers. This plant reportedly spreads in a manner similar to the white gooseneck, but I don't mind that and have instead planted it in a spot where it can roam.

While Lythrum salicaria (Purple Loosestrife) should be avoided like the plague, Lysimachia atropurpurea (purple Gooseneck Loosestrife) is a different plant.

I believe that the invasive loosestrife is Lythrum, not Lysimachia. Lysimachia is in some cultivars and/or species invasive, but not in the same way. I grow one Lysimachia in a pot sunk in the ground, and it's stayed there for years.

I grow this in the San Francisco Bay Area of California in full sun with Scabiosa atropurpurea, Berberis 'Hellmond's Pillar' and Carex buchananii in my "black" garden. It appears to have no invasive tendencies here because it is rather dry; it begins blooming very early here.

Wine red flowers in spikes with wavy blue gray foliage. Growth habit is much like Liatris. Use for backgrounds, naturalizing. Not recommended for wet soils, as it may be invasive. Should be okay in moist soil as a spreader.

Not to be confused with Lythrum virgatum aka "Purple Loosestrife"
