June is prime time to add perennials that will carry your garden through summer and into fall. With warmer soil and fuller root systems, many nursery-grown perennials planted now establish quickly. Below are eight low-fuss, long-blooming options and practical planting tips to help you get nonstop color until the first frost.

Eight low-maintenance perennials to plant in June for season-long color

Agapanthus — bold summer umbels for sunny beds

Agapanthus (African lily) arrives in garden centers in bloom in June. It sends up tall stalks topped with clusters of blue, purple, or white flowers. Hardy in many warm regions, it prefers full sun but tolerates light shade.

• USDA zones: often 8–10.
• Soil: adaptable but benefits from added organic matter.
• Height: some cultivars reach 3–4 feet.
• Planting note: nursery-grown pots establish fast and reward you with immediate blooms.

Purple coneflower (Echinacea) — pollinator magnet and repeat bloomer

Purple coneflower is a native perennial prized for its daisy-like pinkish-purple blooms. Buy potted plants in June to get instant color and attract bees and butterflies all summer.

• USDA zones: 3–10.
• Light: full sun to light shade.
• Care: drought-tolerant once established and deer-resistant.
• Bonus: self-seeds easily, offering future plants without extra effort.

Black-eyed Susan (Rudbeckia) — bright, cheerful midsummer color

Black-eyed Susan provides vivid yellow-orange blooms that pop in borders and meadows. It thrives in many soil types and keeps flowering with minimal deadheading.

• USDA zones: 4–10.
• Light: at least four hours of direct sun.
• Water: fairly drought-tolerant.
• Wildlife value: leave seedheads on some plants to feed birds in winter.

Penstemon — tubular blooms that suit pollinators and dry sites

Penstemon, or beardtongue, shows off spikes of tubular flowers in pinks, whites, and purples. Some varieties bloom later in the season, making them useful for extending garden interest into late summer.

• Light: full sun to part sun.
• Soil: prefers well-drained, often dry soils.
• Regions: many native species are suited to local conditions — consult your nursery.

Astilbe — feathery plumes for shady, moist corners

Astilbe brightens shade gardens with feathery, cone-shaped flowers in pink, red, or white. Its fern-like foliage remains attractive when flowers fade.

• USDA zones: 3–9.
• Light: partial to full shade.
• Soil: rich and consistently moist but well-draining.
• Care tip: avoid letting soil dry out, but don’t overwater.

Allium — architectural purple balls that pollinators adore

Alliums produce globe-shaped flower heads that last for weeks and repel deer and rabbits. While many varieties are planted as bulbs in fall, potted alliums or spring-sprouted plants can be set out in June.

• USDA zones: 4–9 for many types.
• Benefits: striking form, low maintenance, late-summer bloomers available.
• Varieties to consider: round-head, Allium sphaerocephalon, and ‘Summer Beauty.’

Sneezeweed (Helenium) — late-season orange and gold

Sneezeweed lights up borders in late summer and early fall with warm orange and yellow daisies. It was once used in snuffs, giving it its quirky common name.

• USDA zones: 3–8.
• Soil: prefers moist conditions.
• Landscape use: excellent for native plantings and pollinator-friendly beds.

Phlox — clusters of scent and color through summer

Phlox comes in tall and mounding forms and blooms in clusters of pink, white, and red. Plant in June for a dependable display that can continue toward fall.

• USDA zones: 3–9.
• Soil: well-draining is best.
• Water: minimal once established.
• Varieties: choose tall phlox for back borders and low phlox for edges or rock gardens.

Practical tips for planting perennials in June

June brings heat and often less rain. Adjust planting and care to help young perennials thrive.

• Water: give new transplants a deep soak at planting, then water regularly until roots settle.
• Mulch: apply 2–3 inches to conserve moisture and suppress weeds.
• Planting depth: set plants at the same soil level they grew in the pot.
• Soil prep: mix in compost or well-rotted organic matter for better root establishment.
• Shade and heat: protect tender transplants from the hottest afternoon sun for the first week or two.
• Deadheading: remove spent blooms on some species to encourage reblooming.

How to choose the right perennial for your landscape

Select plants that match your local climate, soil, and the light conditions in each part of your garden. Native and regionally adapted varieties often require the least care and reward you with steady blooms.

• Match plant hardiness to your USDA zone.
• Decide where you want summer vs. late-season color.
• Group plants by water needs to make irrigation easier.
• Ask local nurseries for cultivars proven in your area.
