Best Plants for Foundation Planting

The most common landscaping problem I see on Long Island is foundation planting that was installed without thinking about mature size. Yews and hollies planted 2 feet from a foundation, 3 feet on center, that are now 8 feet tall and touching the siding. The plants are healthy; the planting plan was.

The most common landscaping problem I see on Long Island is foundation planting that was installed without thinking about mature size. Yews and hollies planted 2 feet from a foundation, 3 feet on center, that are now 8 feet tall and touching the siding. The plants are healthy; the planting plan was wrong from day one.

Foundation planting has two jobs: frame the house architecturally (scale the building to the landscape), and conceal the exposed foundation wall. Doing both without causing a maintenance problem in 10 years requires knowing mature sizes — not tag sizes, which are often measured at 5 years.

The First Rule: Clearance

Per Penn State Extension, the minimum clearance between a foundation planting and the building wall should be half the plant's mature width. This ensures adequate air circulation (reducing moisture-related diseases), allows access for maintenance, and prevents root systems from contacting the foundation.

A shrub that reaches 6 feet wide needs 3 feet of clearance from the wall — not 1 foot, which is what most installer teams use for aesthetic purposes.

Low Foundation Plants (Under 3 Feet Mature)

Spiraea japonica — dwarf cultivars

Zones 4–9 | Mature: 2–3 ft × 2–3 ft | Full sun

Per Missouri Botanical Garden, 'Little Princess' spirea reaches 2–3 feet with reliable pink summer bloom. S. japonica cultivars are among the most commonly planted low foundation shrubs in the US. They tolerate a range of soils and bloom in summer on new wood, so late-winter shearing does not remove flower buds. Mounded form fits well under windows.

Ilex crenata — compact hollies

Zones 5–8 | Mature: 2–4 ft × 2–4 ft depending on cultivar | Full sun to part shade

Per NC State Extension, Japanese holly (I. crenata) is widely used for formal foundation planting due to its fine texture and tolerance of heavy shearing. 'Compacta' stays under 3 feet; 'Helleri' is even more compact at 18–24 inches. Prefers slightly acidic soil (pH 5.5–6.5). Not as deer-resistant as American holly.

Buxus spp. (Boxwood) — dwarf types

Zones 4–8 | Mature: 2–4 ft (varies widely) | Full sun to part shade

Per Penn State Extension, 'Green Velvet' and 'Winter Gem' boxwoods are compact, cold-hardy to zone 4, and suitable for formal foundation planting. However, boxwood blight (Calonectria pseudonaviculata) has become a serious issue across the Northeast. Per Cornell Cooperative Extension, boxwood blight can defoliate entire hedges quickly in humid conditions. Use disease-resistant cultivars ('SB108' NewGen Independence, 'SB112') if boxwood is important to your design.

Juniperus communis 'Compressa'

Zones 3–8 | Mature: 3–4 ft × 1 ft | Full sun

Per Missouri Botanical Garden, this extremely narrow juniper functions as a vertical accent in foundation planting — useful for flanking entries without blocking windows. Nearly no pruning required. Needs full sun and excellent drainage.

Medium Foundation Plants (3–5 Feet Mature)

Cephalotaxus harringtonia 'Duke Gardens' (Japanese Plum Yew)

Zones 6–9 | Mature: 3–4 ft × 5–6 ft | Shade tolerant

Per NC State Extension, Japanese plum yew is the best yew substitute for the Southeast, where Taxus suffers in summer heat. 'Duke Gardens' stays compact and tolerates shade — important for the north side of a house. Deer-resistant. Slow-growing.

Viburnum dentatum — compact cultivars

Zones 2–8 | Mature: 5–7 ft (standard) — use Blue Muffin at 5 × 5 ft | Full sun to part shade

Per Missouri Botanical Garden, 'Blue Muffin' arrowwood viburnum stays compact (5 feet) and produces blue-black berries that attract birds. Native to eastern North America. Tolerates both wet and dry soils, full sun to part shade. An excellent deer-resistant foundation shrub where the species' natural spread fits the space.

Taxus × media 'Densiformis' (Spreading Yew)

Zones 4–7 | Mature: 4 ft × 8 ft | Part shade to full shade

Per Penn State Extension, 'Densiformis' yew is a compact-spreading form well-suited to foundation corners and north-facing exposures. It takes heavy shearing well. Do not plant in poorly drained soil. Deer typically avoid it, but it is toxic to livestock.

Kalmia latifolia (Mountain Laurel)

Zones 4–9 | Mature: 5–10 ft (slow) | Part shade

Per NC State Extension, mountain laurel is a native broadleaf evergreen with spectacular late-May bloom. It grows slowly and requires acidic soil (pH 4.5–5.5). Best suited for the north or east foundation exposure, under tree canopy, or on a sloped bank. Its native habitat is woodland understory.

Corner and Accent Plants (5–10 Feet Mature)

Ilex × meserveae (Blue Holly)

Zones 4–9 | Mature: 6–10 ft × 6–8 ft | Full sun to part shade

Per Missouri Botanical Garden, blue hollies provide year-round evergreen presence, red berries, and deer resistance. 'Blue Princess' (female) and 'Blue Prince' (male) should be paired. Best at foundation corners where their full mature width has room to develop without constant shearing.

Prunus laurocerasus 'Otto Luyken' (Dwarf Cherry Laurel)

Zones 6–8 | Mature: 4 ft × 6 ft | Part shade to full shade

Per Clemson HGIC, 'Otto Luyken' is the most compact cherry laurel, useful for wide, low spaces on the north side of a house. White flowers in spring, evergreen broad leaves. Tolerates heavy shade that would kill most shrubs. Deer do not prefer it.

Frequently Asked Questions

How far from the house should I plant foundation shrubs? Per Penn State Extension, plant at a distance of at least half the shrub's mature width from the foundation wall. This protects the building from moisture and allows the plant to reach its natural form without constant pruning. Most shrubs also need this distance to ensure their eventual root zone does not press against the foundation.

What grows well on the north side of a house? Per NC State Extension, north-facing foundations receive very limited direct sun in winter. Good choices: Hicks yew (Taxus × media 'Hicksii'), Japanese plum yew (Cephalotaxus harringtonia), mountain laurel (Kalmia latifolia), and 'Otto Luyken' cherry laurel. Avoid plants that need full sun (spirea, juniper, most hollies).

Can I plant right against a concrete block foundation? Per Cornell Cooperative Extension, concrete-block foundations often leach lime, raising soil pH over time. Plants requiring acidic soil (hollies, azaleas, mountain laurel) will show chlorosis within a few years if planted against concrete. Test pH and amend before planting, or choose pH-tolerant species.
