Christina Colorado Blue Spruce
A Compact Blue Spruce That Stays the Right Size for Twin Cities Yards
Christina Colorado Blue Spruce (Picea pungens 'Christina') is a slow-growing semi-dwarf blue spruce cultivar that tops out around 10–15 feet — a fraction of the standard 60+ foot species size. The same striking silver-blue needle color, but in a footprint that fits a Minneapolis foundation bed, an Edina front yard accent, or a tight Maple Grove side-yard. Reliable to -50°F. Ideal when you want the Colorado Blue Spruce look without sacrificing a quarter of your yard to one tree.

Christina Colorado Blue Spruce Uses in Minnesota Landscapes
Compact Specimen for Front Yards
At 10–15 feet mature height, Christina makes a strong specimen accent without overwhelming a typical Minneapolis or St. Paul front yard. Plant 8+ feet from foundations and walkways. The slow growth rate means the plant looks proportional for 15–20 years before reaching mature size.
Mixed Conifer Border
Use Christina in groupings of 3–5 with other dwarf and medium-size conifers (Hetz Midget Arborvitae, 'Montgomery' Blue Spruce, 'Globe' Blue Spruce) for a mixed evergreen bed that holds visual interest year-round without requiring large-tree spacing.
Best Time to Plant Christina Colorado Blue Spruce in Minnesota
Fall — late August through mid-September — is the ideal planting window for evergreens like Christina Colorado Blue Spruce. Soil is still warm enough for root development, cool air reduces transplant shock, and the plant gets 6–8 weeks to establish roots before the typical mid-November ground freeze in the Twin Cities. The earlier window matters specifically for evergreens because they continue losing moisture through their needles all winter, so root establishment before freeze is critical.
Spring (late April through May, after ground thaw) is the second-best window — you get a full growing season ahead. Avoid summer planting (June–August) when possible; if you must, water heavily and mulch deeply. Never plant after mid-October or before late April, when frozen ground or frost-heaving will kill new roots.
How to Plant Christina Colorado Blue Spruce
- Dig wide, not deep — 2–3x the root ball width, same depth. In heavy clay, dig even wider (3–4x).
- Check for clay hardpan — if water pools in the hole, break through the clay layer or mound-plant 2–3 inches above grade to improve drainage.
- Backfill with native soil mixed with 20–30% compost. Don't fill the hole with pure compost — it creates a "container" effect that traps water around the roots.
- Spacing — 8–10 feet apart for mixed conifer border; 10+ feet for individual specimens.
- Build a 3–4 inch water basin around the plant to direct water to the roots. Flatten or remove the basin in late October to prevent ice damage over winter.
- Mulch with 2–3 inches of shredded bark or wood chip mulch, kept 2 inches away from the trunk. Do NOT use gravel mulch — it doesn't insulate roots in Minnesota winters.
Watering Christina Colorado Blue Spruce 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 during active growth; less if rainfall is adequate (Minnesota averages roughly 3 inches/month June–August)
- Stop watering 2–3 weeks before ground freeze (typically late October in Twin Cities metro). Continued late-fall watering can push tender new growth that gets killed by winter.
- One deep watering in early December is a good idea for evergreens if fall has been dry — it helps the plant resist winter desiccation.
After Year One
- Established Christina Colorado Blue Spruce rarely needs supplemental water. Water deeply during droughts (2+ weeks of no rain combined with temps above 80°F).
- Soak to 6–8 inches depth, every 7–14 days during dry spells. Let natural rainfall do the rest.
Drip Irrigation in Minnesota
Drip works well for Christina Colorado Blue Spruce if your beds already have a system. Place emitters 12–18 inches from the trunk. Always blow out lines and shut off the timer by early October — frozen drip lines split.
Will Christina Colorado Blue Spruce survive a Minnesota winter?
Yes. Same parent species as standard Colorado Blue Spruce — rated to USDA zone 2 (-50°F). No protection needed.
How does it differ from 'Fat Albert' or 'Hoopsii'?
'Fat Albert' is similar size (10–15 ft) but more pyramidal; Christina is denser and more rounded-pyramidal. 'Hoopsii' grows to 20–25 ft — significantly larger. Christina is the most compact of the three.
How fast does Christina grow?
Slow — 4–8 inches per year. A 6-gallon plant (~3–4 ft tall) reaches mature 10–15 ft in 15–20 years.
Will deer eat it?
Rarely. The stiff sharp needles of all Colorado Blue Spruce cultivars deter deer browsing in nearly all situations.
Can I plant Christina near a foundation?
Yes — 8 feet from the foundation is enough given the 6–8 ft mature width. Avoid planting closer than that to allow for root system and snow shedding off rooflines.

How Many Christina Colorado Blue Spruce Do I Need?
Christina is a specimen and grouping conifer, not a hedge plant. For a front-yard accent, one plant set 8–10 feet from the foundation or walkway does the job. For a mixed conifer border, plant in groups of 3–5 spaced 8–10 feet apart — the 6–8 foot mature width fills the gaps over time while the slow growth keeps the bed in proportion for years. Pair one Christina per 15–20 feet of bed as the mid-height "anchor," with dwarf globes and grasses layered in front.
Christina Colorado Blue Spruce Season-by-Season in Minnesota
- Spring: Fresh new growth pushes in late May — the new needles emerge the brightest, most silvery blue of the year and slowly firm to steel-blue by midsummer.
- Summer: Dense rounded-pyramidal form in full silver-blue color; the cool tone reads almost gray-blue against green lawns and makes hot July beds feel cooler.
- Fall: Color holds steady while deciduous neighbors turn — the blue pops hardest against orange maples and golden grasses in September and October.
- Winter: The star season. Stiff blue needles hold snow in tiers and keep full structure and color through -30°F stretches when everything else in the bed is bare.

Is Christina Colorado Blue Spruce Right for Your Yard?
Christina thrives in full sun (6+ hours — the blue color fades in shade), well-draining clay-loam, and any Twin Cities deer pressure; it asks for almost nothing once established and shrugs off -50°F. Give it an 8-foot circle and it stays in scale with a standard suburban lot for decades. Not a fit if your site is shady or stays soggy — blue spruce sulks in wet feet and shade, and in a low spot that holds spring water you'll be happier with an arborvitae.
