Small Tree for Narrow Space: Thundercloud Plum

Prunus cerasifera 'Thundercloud' for a Tight, Sunny Spot

For a 5-ft-wide planting strip between fence and driveway (west sun, 9 ft from house, Zone 9b/10a), Thundercloud plum offers multi-season appeal in a compact form.

Key Attributes

• Size: 15–20 ft tall, 10–15 ft wide—can be maintained smaller with pruning.
• Spring: Pale pink single flowers early (February–March).
• Foliage: Deep purple leaves hold color spring through summer; copper tones in fall.
• Form: Upright, rounded canopy; branches can be raised above head height for clearance.
• Roots: Non-aggressive; unlikely to heave pavement with proper irrigation.

Culture

• Full sun for best foliage color; tolerates light shade.
• Well-drained soil; amend clay with compost.
• Moderate water once established; avoid wet feet.
• Prune in late winter to shape and remove crossing branches.

Alternatives to Consider

• Lagerstroemia 'Acoma' (crape myrtle, 10 ft, white flowers, exfoliating bark).
• Cercis canadensis 'Forest Pansy' (redbud, purple leaves, 15 ft, needs more width).
• Malus 'Prairifire' (crabapple, 15 ft, magenta flowers, persistent fruit, disease-resistant).

Thundercloud plum's foliage color provides the "beautiful feature" year-round, not just in bloom.
