About Britt-Marie Crawford Ligularia

Ligularia dentata 'Britt-Marie Crawford' · also called Britt-Marie Crawford ligularia, dark-leaved goldenray · flowering

'Britt-Marie Crawford' is a dramatic moisture-loving perennial grown for huge rounded leaves of deep chocolate-maroon, glossy above and beetroot-purple beneath, topped in late summer by bold clusters of orange-yellow daisy flowers. A statement plant for damp shade, pond margins and bog gardens, its dark foliage holds colour best in cooler, consistently moist conditions.

Mature size: 90-100 cm (36-40 in) tall in flower and 75-90 cm (30-36 in) wide, forming a substantial leafy clump.

Watch for — Dramatic midday wilting: The large leaves flop alarmingly in sun and heat even when soil is moist, recovering by evening. Reduce stress with afternoon shade and consistently wet soil; persistent wilting means the roots are too dry.

How to tell britt-marie crawford ligularia needs repotting

Repotting on a calendar is less reliable than reading the plant. For britt-marie crawford ligularia, watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for britt-marie crawford ligularia) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot britt-marie crawford ligularia

Only every 2–4 years, when genuinely crowded. Britt-Marie Crawford Ligularia is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Bold, clump-forming herbaceous perennial with large rounded basal leaves and tall branched flower stems rising above the mound in late summer. Dies back fully in winter..

What size pot to step britt-marie crawford ligularia up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Britt-Marie Crawford Ligularia positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping britt-marie crawford ligularia into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot britt-marie crawford ligularia

Early spring, just as new growth restarts, is the ideal window for britt-marie crawford ligularia. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting britt-marie crawford ligularia

Confirm it actually needs it. Slide britt-marie crawford ligularia out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip britt-marie crawford ligularia out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh deep, fertile, moisture-retentive to boggy, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water britt-marie crawford ligularia again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for britt-marie crawford ligularia

Britt-Marie Crawford Ligularia wants deep, fertile, moisture-retentive to boggy. Wants rich, heavy, humus-laden soil that holds water, slightly acidic to neutral. Ideal beside water or in clay-rich ground; incorporate plenty of organic matter and mulch heavily to lock in moisture. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting britt-marie crawford ligularia — frequently asked questions

How often should you repot britt-marie crawford ligularia?

Only every 2–4 years, when genuinely crowded for britt-marie crawford ligularia. Only repot britt-marie crawford ligularia every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using deep, fertile, moisture-retentive to boggy. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does britt-marie crawford ligularia need?

When is the best time of year to repot britt-marie crawford ligularia?

Does britt-marie crawford ligularia like to be root-bound?

Yes — britt-marie crawford ligularia genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise britt-marie crawford ligularia after repotting?

Not immediately. Wait about 4 weeks after repotting britt-marie crawford ligularia. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
