Show Off Forsythia
A Heavy-Blooming Forsythia Packed with Gold from Top to Bottom
Show Off Forsythia (Forsythia × intermedia 'Mindor') reinvented the classic forsythia by packing its bright yellow flowers densely all along the stems — not just at the tips — for a fuller, brighter early-spring display on a more upright, tidy plant. Like all forsythia it blooms best in a sheltered Minnesota spot where snow and wind protection guard the buds. Whether you're brightening a protected border in Edina, a south-facing foundation in Woodbury, or an informal screen in Maple Grove — Show Off delivers a bold gold show in zone 4b–5a yards.
Show Off Forsythia Plant Details
| Attribute | Detail |
|---|---|
| Scientific Name | Forsythia × intermedia 'Mindor' |
| Common Names | Forsythia, Border Forsythia, Show Off Forsythia |
| Mature Height | 5–6 feet |
| Mature Width | 4–5 feet |
| Growth Rate | Fast — upright, tidy habit |
| Sun | Full sun to part shade. Full sun gives the heaviest bloom. |
| Water | Moderate. Consistent moisture the first year; very adaptable once established. |
| USDA Zones | 5–8 (Twin Cities is zone 4b–5a) — root-hardy here; flower buds bloom most reliably in a sheltered spot |
| Soil | Very adaptable — tolerates Minnesota clay-loam and most soils. |
| Foliage | Deciduous — green leaves emerge after the flowers. |
| Winter Hardiness | Root-hardy in the metro and a heavy budder, but a hard, open winter can reduce bloom. A sheltered spot with snow cover gives the best flowering. |
| Deer Resistance | Moderately deer-resistant. |
| Bloom | Bright yellow flowers densely along the stems in very early spring, on old wood. |

Bold early-spring color
Its dense, top-to-bottom flowering makes Show Off one of the brightest early bloomers. Site it in a protected, sunny spot in Edina or Plymouth for the heaviest display.
Informal screens and borders
Its upright, tidy habit suits an informal screen or a back-of-border anchor that fills in fast.
Cut branches for forcing
Cut budded stems in late winter to force indoors for an early taste of spring.
Best Time to Plant Show Off Forsythia in Minnesota
Fall (late August–early October) is the ideal planting window. Soil is still warm for root development, cool air reduces transplant stress, and the plant gets 6–8 weeks to establish roots before ground freeze (typically mid-November in the Twin Cities).
Spring (late April–May, after the ground thaws) is the second-best window, giving the shrub a full season to establish before its first winter.
Avoid summer planting (June–August) when possible. Never plant after mid-October or before late April — frozen ground or frost-heaving kills new roots.
How to Plant Show Off Forsythia
- Choose a sheltered, sunny spot where snow collects, to protect the flower buds.
- Dig wide, not deep — 2–3× the root ball width, same depth as the container.
- Backfill with native soil mixed with 20–30% compost; forsythia is not fussy about soil.
- Space 4–5 feet apart for a screen; give it room to fill in.
- Build a water basin; flatten it before winter to avoid ice damage.
- Mulch 2–3 inches with shredded bark, kept off the stems. Prune right after flowering — it blooms on old wood.
Watering Show Off Forsythia in Minnesota
First Year Watering Schedule
- Weeks 1–2: Every 1–2 days, deep and slow (15–25 minutes)
- Month 1–2: Every 3–4 days
- Month 3–6: Every 5–7 days; less if rainfall is adequate
- Stop watering 2–3 weeks before ground freeze (typically late October in the Twin Cities metro).
After Year One
Established forsythia is tough and drought-tolerant, needing water only during extended dry spells. Let natural rainfall do most of the work.
Drip Irrigation in Minnesota
If used, place emitters 12–18 inches from the trunk. Always winterize the system — blow out the lines before freeze and shut timers off by early October.
How is Show Off different from old forsythias?
It blooms densely all along the stems rather than just at the tips, on a more upright, tidy plant — a much fuller display.
Will it bloom reliably in Minnesota?
It's root-hardy and a heavy budder, but like all forsythia its buds can be reduced in a hard, open winter. Plant it sheltered with good snow cover; the extra-hardy 'Northern' types and Show Off Starlet are the most reliable bloomers in the coldest sites.
When should I prune it?
Right after flowering — forsythia blooms on old wood, so later pruning removes next spring's flowers.
Can I force the branches indoors?
Yes — cut budded stems in late winter and bring them inside to force into early bloom.
