Types of Lysimachia – Mat, Upright, or Gooseneck guide illustration

Choose lysimachia by habit before color. Golden Creeping Jenny is a creeping jenny mat. Yellow Loosestrife is an upright yellow spike. Gooseneck Loosestrife is gooseneck. They do not share one pot or one edge.

Goldilocks is a compact mat. Alexander and Fringed Loosestrife are upright yellow. Beaujolais is a purple spike on Lysimachia, not Lythrum. Shop habit first.

Moisture stays the same across garden types. This page only sorts habit. Care stays on the grow page. Plant-out stays on the planting page.

Browse all lysimachia by group in the catalog below. Use the groups as a shop filter, not as three care essays.

Wrong lysimachia buys that look like a types page

Lythrum on a loosestrife tag: refuse the wetland weed. Garden purple spikes are Lysimachia atropurpurea. Confirm the genus.

Golden Creeping Jenny as a polite front-border filler: creeping jenny runs. Goldilocks still needs an edge or a pot.

Gooseneck Loosestrife in a tiny mixed skirt: gooseneck rhizomes swallow meek neighbors. Give it a managed block.

Firecracker as a groundcover: it is an upright with purple foliage, not a mat. Height is on the profile.

What each type actually offers

Creeping jenny mats: Lysimachia nummularia mats for moist ground or a drained pot. Stems root as they run. Edge them.

Upright yellow loosestrife: Punctata, ciliata, Alexander, and Firecracker. Summer yellow spikes on rhizomatous clumps. Give them a block you can lift.

Purple and gooseneck loosestrife: Beaujolais (Lysimachia atropurpurea) and gooseneck clethroides. Confirm the genus. Plan a barrier.

Habit is the last check on the bag after you refuse the wrong genus. A mat sits at the path or in a pot. A spike belongs in a block with an edge.

If two bags look the same in the photo, open the species. Nummularia is a mat. Punctata and ciliata are upright yellow. Clethroides is gooseneck. Color is the last sort, not the first.

A jumbo pot of gold foliage is still creeping jenny. A small plug of punctata is still an upright that will run. Size of the nursery pot is not habit.

Full catalog by type group (8)

Groups follow creeping jenny, upright yellow, and purple or gooseneck types. Photograph the bag. Common names proliferate.

Write habit on the bag before it goes in the shed. A mat versus spike mismatch is the usual types-page mistake, not a fertilizer mistake.

Compare a mat next to a spike in person when you can. Pack art lies. Repeat once before payment: habit, then spread, then color.

Where care, partners, and planting live

Moisture and containment: How to Grow Lysimachia. Partners: Lysimachia Companion Plants. When and how to plant: Planting Lysimachia.

A drained pot is still the usual stop for creeping jenny. Patio steps live on Lysimachia in Containers. Companions and planting are separate URLs.

Use this page to refuse a wrong habit, then leave. Do not reread the groups as three mini care guides. Moisture does not change because the flower is white instead of yellow.

If the catalog row is thin in a group, that is a stock gap, not a missing class. Open the plant profile and still apply the same habit check you used on the named examples above.

A mixed tray labeled only “loosestrife” is a habit gamble. Split mats and spikes into two holes. One jammed row is how gooseneck flops onto creeping jenny.

Moneywort and creeping jenny are the same nummularia job. Green-leaf forms run like gold forms. Color of the leaf does not make the plant polite.

Variegated punctata such as Alexander is still an upright rhizome plant. The cream leaf is a shop cue. The spread is the garden job.

Fringed loosestrife (ciliata) takes a bit more shade if the soil stays moist. It is not a dry woodland groundcover. Do not copy a hosta-only shade plan onto a dry slope.

If you are buying for a pot, start with creeping jenny. If you are buying for a damp border block, start with upright yellow or gooseneck. Purple spikes are a third cart after the Latin check.

Write the habit on your receipt. Next spring the photo on the crate will still lie. Your note will not. Mat or spike first, then color, then how much edge you can actually keep.

A florist bunch of gooseneck does not tell you winter spread. Cut stems are a shop job. Rhizomes are a garden job. Pay for the garden job first.

Green creeping jenny is the same runner as gold. If you want a quieter leaf, you still set the same edge. Leaf color is not containment.

Do not shop by the word loosestrife alone. That word covers garden Lysimachia and the wetland weed. Open the Latin, then the habit, then the height in inches.

A trough mix of gold jenny and a small upright spike can work if the pot is deep and drained. A shallow bowl with both will rot the spike and spill the mat. Match habit to volume.

Height in inches on the tag beats a lifestyle photo. A two-inch mat and a thirty-inch spike can share a genus and still fail in the same hole. Read the inches.

If the bag lists only a color, ask for the species. Yellow is not a type. Mat versus spike is.

FAQ

How do I choose a lysimachia type?

Pick creeping jenny, upright yellow, or gooseneck / purple spike by habit, then color.

Golden Creeping Jenny is a mat. Yellow Loosestrife is an upright spike. They do not share one pot size.

Is Beaujolais purple loosestrife?

Beaujolais is Lysimachia atropurpurea. The wetland weed is Lythrum salicaria. Confirm the genus.

Where is care?

How to Grow Lysimachia.

Does habit change planting?

Mats want an edge or a pot. Spikes want a block. See Planting Lysimachia.

Can I mix a mat and a spike in one bed?

Yes, if you edge the mat and give the spike its own block. Do not jam both into one small hole.

What is gooseneck loosestrife?

Lysimachia clethroides — arched white spikes on a spreading clump, not a groundcover mat.

Is Firecracker a creeping jenny?

No. Firecracker is an upright with purple foliage. See the upright yellow group.
