20 Truly Low-Maintenance Perennials
"Low-maintenance" is one of the most abused phrases in gardening. Plants labeled low-maintenance at the nursery still require watering during establishment, occasional division to maintain vigor, and sometimes disease management. The phrase is relative -- relative to.
"Low-maintenance" is one of the most abused phrases in gardening. Plants labeled low-maintenance at the nursery still require watering during establishment, occasional division to maintain vigor, and sometimes disease management. The phrase is relative — relative to what?
I use three criteria for this list. A genuinely low-maintenance perennial must: (1) tolerate average or below-average soil without amendment, (2) survive dry spells without irrigation once established, and (3) require division no more than every 4–5 years. I exclude plants that are low-maintenance only in one region or only on optimal soils.
I grow several of these at my place in Melville — catmint, switchgrass, black-eyed Susan, coneflower, sedum 'Autumn Joy', Siberian iris, and Russian sage. All of them largely take care of themselves once established.

Ground-Level to 18 Inches
1. Sedum 'Autumn Joy' (Hylotelephium 'Herbstfreude')
Zones 3–9 | Sun: full | Drought: excellent | Division: every 4–5 years
Per Missouri Botanical Garden, 'Autumn Joy' tolerates drought, clay, and poor fertility. It is essentially pest-free. I have grown it for six years and it has never needed watering beyond the first season. The only task is cutting back the dried stems in late March.
2. Geranium macrorrhizum (Bigroot Geranium)
Zones 3–8 | Sun: full to full shade | Drought: excellent | Division: every 5+ years
Per Penn State Extension, bigroot geranium is one of the most drought-tolerant and shade-tolerant perennial ground covers available. The aromatic roots produce rhizomes that spread slowly to fill space. Pink flowers in May–June. It holds its foliage late into fall and turns orange-red before dropping.
3. Ajuga reptans (Bugleweed)
Zones 3–9 | Sun: part shade to full shade | Drought: moderate | Division: rarely needed
Per NC State Extension, ajuga spreads quickly by runners to form a dense mat that suppresses weeds. Purple flower spikes in spring. It can spread into lawns and adjacent beds — a minor management task. 'Burgundy Glow' and 'Catlin's Giant' are good cultivars. Best in part shade; full sun in dry conditions causes crown rot.
4. Liriope muscari (Lilyturf)
Zones 5–10 | Sun: sun to shade | Drought: excellent | Division: every 4–5 years
Per Clemson HGIC, lilyturf is one of the most versatile low-maintenance edging perennials for zones 5–10. It handles heat, drought, shade, and compacted soil better than most options. Cut back the tattered foliage in late February/early March before new growth emerges.
