How to Grow Geum
'Mrs Bradshaw' from Seed
The century-old cottage garden scarlet — warm rich scarlet-red semi-double ruffled flowers with golden stamens floating on wiry 45–60cm stems from May to September; a Hardy Perennial H7 AGM that tolerates clay, grows in sun or shade, and delivers a four-month display when deadheaded; the bridging plant between spring and summer; fuzzy burnished seed heads for drying; divide every 2–3 years to keep it perpetually vigorous
Geum 'Mrs J. Bradshaw' is perhaps the most famous Geum in the history of English cottage gardening — a variety so long-established and so reliably excellent that it has continued to be grown, divided, and shared between gardens for well over a century since its introduction. The flowers are semi-double, ruffled, and in a warm, rich scarlet-red — not a harsh fire-engine red, but the slightly orange-toned, strawberry-touched red of a good cottage garden, the kind of red that feels entirely natural alongside pinks, purples, blues, and the soft, faded tones of an established mixed border. Each bloom centres on a cluster of prominent golden stamens that provide a vivid contrast against the red petals, making the flower look particularly fresh and clean even in the height of a hot summer.
The stems are wiry and slender, 45–60cm tall, holding the flowers well above the attractive mound of soft, scalloped semi-evergreen foliage at the base. The effect from a distance is of floating scarlet — dozens of individual flowers hovering in the air above a low, leafy mound, in constant gentle motion on their slender stems. With consistent deadheading, this display continues from late May right through to September — one of the longest reliable flowering seasons of any hardy perennial available from seed. And when flowering finally concludes, the fuzzy, burnished reddish-brown seed heads that develop provide a bonus crop of drying material for late-season arrangements.

Understanding the Plant
The Most Famous Geum — Why It Has Endured
Mrs J. Bradshaw was raised and introduced in the early 20th century, and the fact that it is still widely grown, still commonly divided and passed between gardeners, and still holds the RHS Award of Garden Merit, is the clearest possible evidence of its quality. A plant that had failed to deliver consistent results would have disappeared from gardens within a generation. The continued presence of Mrs Bradshaw in cottage gardens throughout the UK is the accumulated endorsement of a century of gardeners finding it exactly as reliable and exactly as beautiful as its reputation suggests.
The Bridging Plant — Between Spring and Summer
Mrs Bradshaw starts flowering in late May, just as tulips are finishing and before most summer annuals have begun. It occupies the crucial gap in the cottage garden flowering calendar between the spring biennial display and the main summer annual show. This bridging quality — warm scarlet-red in late May and June when the garden most needs it — is one of the reasons it has been so valued for so long. Combined with its tolerance of clay soils and its semi-evergreen foliage that provides year-round ground cover, it earns its place in the border even before the first flower opens.
The Seed Heads — A Bonus Harvest
After the scarlet petals fall, Geum develops fuzzy, burr-like seed heads that turn a deep reddish-brown as they ripen. These are genuinely beautiful in their own right and cut well for dried arrangements, adding a rustic, textural quality alongside more conventional dried flowers. Allow some stems to ripen fully before cutting — the seed heads continue developing after the petals fall and are at their best when fully brown and the individual awns have fully extended. Leave some on the plant for self-seeding and to provide interest through autumn.
Sowing & Growing On
Surface Sow with Patience
Geum Mrs Bradshaw seeds need light and consistent warmth (18–20°C) to germinate. Germination is variable, typically 14–28 days. Keep the tray in a bright position and resist the impulse to discard ungerminated trays — late germinators within a single sowing are common and often produce excellent plants.
-
Surface sow indoors February–April at 18–20°C. Seeds need light — cover with only the finest dusting of vermiculite. Germination 14–28 days, occasionally longer. Keep consistently warm and moist. Mrs Bradshaw germinates somewhat more reliably than Lady Stratheden but still benefits from patience if germination is slow.
-
Prick out into individual 9cm pots when seedlings have 2–3 true leaves. Grow on at 12–15°C in bright conditions. Geum seedlings establish and grow quickly — ready for planting out 8–10 weeks after germination.
-
Plant out in spring–early summer in full sun or partial shade, 40cm apart. Geums tolerate clay soils well. Add a handful of grit to very dense, slow-draining clay planting holes to reduce winter waterlogging risk at the crown.
-
Deadhead consistently — cut spent stems to the base of the plant for a 4-month flowering season. Cut the entire flower stem back to the basal foliage as soon as petals fall. Allow some late-season stems to ripen their seed heads fully for drying and for mild self-seeding.
Growing On & Care
Deadheading — Extended Season
Cut every spent flower stem back to the basal foliage as soon as the petals fall. This prevents seed formation, redirects the plant's energy into new bud production, and maintains the scarlet display continuously from May through September. New flowering stems emerge from the base consistently when old ones are promptly removed. Leaving some late-season stems to set seed provides both self-seeding and dried seed head harvest.
Semi-Evergreen Ground Cover
The basal mound of soft, scalloped strawberry-like leaves is semi-evergreen — remaining through all but the harshest winters to provide continuous ground cover below the flowering stems. This winter foliage is attractive in its own right and suppresses weeds effectively. Cut back any tatty or frost-damaged foliage in early spring before new growth begins, but do not remove the whole mound — new leaves emerge from the base through spring.
Division for Longevity
Divide Mrs Bradshaw every 2–3 years in early autumn or early spring to maintain peak flowering vigour. Dig the whole clump, discard the oldest woody central portion, and replant vigorous outer sections 40cm apart. This simultaneously rejuvenates the plant and provides multiple new plants free of charge — a Mrs Bradshaw clump divided every 3 years will gradually fill a whole border with its floating scarlet flowers.
Dried Seed Heads
Allow some late-season flower stems to develop fully into the fuzzy, reddish-brown seed heads after petals fall. Cut when the seed heads are fully developed but before they begin to shatter. Hang upside down in small loose bunches in a warm, dark, well-ventilated space. The burnished reddish-brown bobbles add a warm textural element to dried arrangements and complement the terracotta, rust, and earthy tones of autumn botanical arrangements particularly well.
Design Companions
The warm scarlet-red of Mrs Bradshaw pairs most naturally with: soft blues (Forget-me-not Blue rising from below the scarlet stems creates a classic, vibrant cottage garden picture); lime-green (Bupleurum griffithii provides the zesty foil that makes scarlet appear even more vivid); and soft yellows (Lady Stratheden grown alongside Mrs Bradshaw provides the warm yellow-and-red complementary cottage garden planting that has been grown together in English gardens for generations).
Clay Tolerance and Hardiness
Mrs Bradshaw is one of the few ornamental perennials that actually performs well in heavy clay soils — the moisture-retentive nature of clay suits its preference for consistent soil moisture. Combined with its H7 hardiness (-20°C), this makes it one of the most versatile and robust perennials available from seed. It grows in sun or partial shade, tolerates the full range of British weather conditions, and asks only for deadheading and periodic division in return for a four-month display every year.

| Problem | Likely Cause | What to Do |
|---|---|---|
| Germination slow | Normal variability | Mrs Bradshaw germination is variable — 14–28 days is typical. Keep the tray warm (18–20°C), in bright light, and consistently moist. Do not discard trays prematurely. Late germinators within a single batch are common. |
| Short flowering season | Deadheading inconsistent | Deadhead every spent stem to the base as soon as petals fall. Cut the complete stem back to the basal foliage — do not leave stubs. A plant properly deadheaded throughout the season flowers for 4 months; one neglected slows dramatically by July. |
| Reduced vigour over time | Crown exhaustion; needs division | Divide every 2–3 years in early spring or autumn. Discard the oldest woody central section and replant vigorous outer portions. Flowering is immediately restored in divided plants. |
| Crown rot in dense clay | Winter waterlogging | Add a handful of grit to the planting hole in very dense, slow-draining clay. The moisture-retentive quality of most clay soils actually suits Mrs Bradshaw well; only severely waterlogging conditions are problematic. |
