How to propagate Siberian Bugloss 'Hadspen Cream' (Brunnera macrophylla) — step by step

Also called Hadspen Cream Siberian Bugloss, False Forget-Me-Not, Great Forget-Me-Not.

The best way to propagate siberian bugloss 'hadspen cream'

The reliable, beginner-friendly way to propagate siberian bugloss 'hadspen cream' is division of the crown / rhizome. It suits this species because of how it grows: clump-forming herbaceous perennial, spreading slowly by rhizomes. Divide established clumps in early spring, ensuring each division has healthy roots and shoots. Can also be propagated from root cuttings taken in late autumn or winter. Seed propagation produces green-leaved seedlings — variegated cultivars must be propagated vegetatively.

For the wider picture of which technique suits which plant, our guide to plant propagation methods compares water, soil, leaf, division and offset propagation side by side.

Step-by-step: propagating siberian bugloss 'hadspen cream'

Water and unpot. Water siberian bugloss 'hadspen cream' the day before, then slide the whole plant out and gently shake or wash soil off the root mass.
Find natural splits. Look for separate crowns or fans of growth. Tease them apart by hand where you can; use a clean knife only where roots are matted.
Cut into divisions. Make divisions that each keep several healthy growing points and a strong share of roots — bigger divisions recover faster.
Trim and repot. Trim any rotten roots, then pot each division at its original depth in humus-rich, well-drained but moisture-retentive loam.
Aftercare. Water in, keep out of harsh sun and slightly humid for 3–6 weeks while roots re-establish. Hold off feeding until new growth appears.

The alternative method

If the main route does not suit your plant or setup, potting up naturally offsetting side crowns is the next best option for siberian bugloss 'hadspen cream'. Many of these plants also throw side crowns or offsets you can pot up individually without lifting the whole plant, which is gentler if the parent is large or established.

Timeline to roots

Realistically: full plants from day one; settles in 3–6 weeks. These numbers assume spring or summer warmth and bright indirect light. In a cold, dark room — or in winter dormancy — the same siberian bugloss 'hadspen cream' propagation can take twice as long or stall completely, so do not panic if progress looks slow out of season. Patience beats poking: disturbing a forming root system to “check” on it is a common way to set it back.

Common failure points

Making divisions too small, with too few roots or growing points to recover.
Dividing in the heat of summer instead of spring or at repotting, adding avoidable stress.
Planting divisions too deep or too shallow relative to their original soil line.
Propagating off a stressed, pest-ridden or recently-repotted siberian bugloss 'hadspen cream' — always take material from a healthy, established parent.

When to do it

The best window is spring, or at repotting time. Propagation is energetically expensive for a plant, and it only has the spare resources to build new roots when it is already growing actively, warm and well-lit. Out-of-season attempts are not pointless, but expect lower success and a longer wait.

Aftercare

Water divisions in well, keep them out of harsh sun and slightly humid for three to six weeks, and delay feeding until new siberian bugloss 'hadspen cream' growth appears. Bigger divisions bounce back fastest. Match the parent's needs as the new siberian bugloss 'hadspen cream' settles: Best in dappled shade or partial shade. Deep shade reduces flowering but the foliage remains attractive. Direct summer sun causes severe leaf scorch on variegated forms.

Siberian Bugloss 'Hadspen Cream' propagation — frequently asked questions

What is the best way to propagate siberian bugloss 'hadspen cream'?

Division of the crown / rhizome is the most reliable method for siberian bugloss 'hadspen cream'. Propagate siberian bugloss 'hadspen cream' by division. Lift the plant, tease or cut the crown into clumps that each keep healthy roots and several growing points, then repot. You get full-sized plants from day one; they settle in 3–6 weeks. Spring or repotting time is ideal.

Do you need a node to propagate siberian bugloss 'hadspen cream'?

For siberian bugloss 'hadspen cream' the rooting structure is division of the crown / rhizome, so a classic "node" matters less than starting with the right plant material — Lift the plant, tease or cut the crown into clumps that each keep healthy roots and several growing points, then repot.

How long does it take siberian bugloss 'hadspen cream' to root?

Full plants from day one; settles in 3–6 weeks. Timing varies with warmth and light — propagations move fastest in spring and summer when the plant is in active growth, and can stall almost completely in a cold, dark winter.

What is the best time of year to propagate siberian bugloss 'hadspen cream'?

Spring, or at repotting time. Root and shoot development is metabolically demanding, so propagating during the active growing season gives noticeably higher success rates and faster results than attempting it in dormancy.

Can you propagate siberian bugloss 'hadspen cream' in water?

Not really — siberian bugloss 'hadspen cream' is divided into rooted clumps and potted straight into mix. Water propagation does not apply to division; each piece already has its own roots.
