Spring Glory Forsythia
Spring Glory Forsythia
Bright Early-Spring Gold — Best in a Sheltered Minnesota Spot
Spring Glory Forsythia (Forsythia × intermedia 'Spring Glory') bursts into bright, pale-yellow bloom in very early spring, one of the first shrubs to color up after a long winter. It's fast-growing and easy, but it's worth knowing up front: its flower buds are only hardy to about -10°F, so in the Twin Cities the most reliable bloom comes on the lower stems protected by snow, or in a sheltered microclimate. Whether you're brightening a protected corner in Edina, a south-facing foundation in Woodbury, or a sheltered border in Maple Grove — Spring Glory delivers an early gold show in zone 4b–5a yards.
Spring Glory Forsythia Plant Details
| Attribute | Detail |
|---|---|
| Scientific Name | Forsythia × intermedia 'Spring Glory' |
| Common Names | Forsythia, Border Forsythia, Spring Glory Forsythia |
| Mature Height | 6–8 feet |
| Mature Width | 6–8 feet |
| Growth Rate | Fast — upright, arching 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) — stems are root-hardy here, but flower buds are zone-5 tender |
| Soil | Very adaptable — tolerates Minnesota clay-loam and most soils. |
| Foliage | Deciduous — green leaves emerge after the flowers; some yellow-purple fall tones. |
| Winter Hardiness | The plant is root-hardy in the metro, but flower buds (on old wood) survive only to about -10°F — so in a cold, open winter you may get bloom mainly below the snow line. A sheltered spot improves bloom. |
| Deer Resistance | Moderately deer-resistant. |
| Bloom | Pale-yellow flowers in very early spring, on bare branches, on old wood. |
Spring Glory Forsythia Uses in Minnesota Landscapes
Early-spring color in sheltered spots
Forsythia is one of the first shrubs to bloom. To get the most flowers from Spring Glory in the Twin Cities, site it in a protected microclimate — a south or east foundation, out of harsh wind — where snow cover and shelter protect the buds.
Informal screens and banks
Its fast, arching growth makes a quick informal screen or a great choice for cascading down a slope or bank in Burnsville or Eden Prairie.
Cut branches for forcing
Cut budded stems in late winter and bring them indoors to force into early bloom — a classic way to enjoy forsythia regardless of outdoor bud hardiness.
Best Time to Plant Spring Glory 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 Spring Glory Forsythia
- Choose a sheltered, sunny spot — a south or east foundation, out of harsh wind, 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 6–8 feet apart for a screen; give it room for its arching habit.
- Build a water basin to direct water to the roots; 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, so late-spring or summer pruning removes next year's flowers.
Watering Spring Glory 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.
Will Spring Glory bloom reliably in Minnesota?
Not always top-to-bottom. The plant is root-hardy here, but its flower buds are only hardy to about -10°F, so in a cold, open winter you may get flowers mainly on stems that were under snow. A sheltered spot helps. For the most reliable bloom in the Twin Cities, the extra-hardy 'Northern Sun', 'Northern Gold', and Show Off Starlet types are better bets.
When should I prune it?
Right after it finishes flowering. Forsythia blooms on old wood, so pruning in late spring, summer, or fall removes the buds that would flower next spring.
How fast does it grow?
Quickly — it's a vigorous, arching shrub that fills in fast for an informal screen.
Can I force the branches indoors?
Yes — cut budded stems in late winter and bring them inside to force into early bloom, a great way to enjoy the flowers regardless of outdoor bud hardiness.
