Perennial Flowers for Spring
Spring bloomers do double duty: they're the first real color after a gray winter, and the way they perform in their first few weeks tells you a lot about how well they were sited.
What Blooms First
Peony is the headline spring perennial on this site — most varieties bloom in mid-to-late spring, with huge, often fragrant flowers on a plant that, once established, needs almost no yearly intervention. Coral bells begins sending up airy flower stalks in mid-to-late spring as well, though it's grown mainly for foliage that looks good long before and after that bloom window. Neither of these is technically the very first thing to flower — for that, gardeners typically rely on bulbs like crocus and daffodil, which aren't perennial flowers in the herbaceous-perennial sense covered on this site but are worth planting alongside these for late-winter color.
Spring Planting: Timing and Technique
Spring is one of the two best windows to plant new perennials (the other is early fall). Wait until the soil is workable and no longer waterlogged from snowmelt — working wet clay soil compacts it and undoes any benefit of planting early. Dig a hole roughly twice the width of the root ball and no deeper than the ball itself; planting too deep, especially with peony, is one of the most common reasons a plant fails to bloom for the first several years. Water thoroughly at planting time and keep new transplants consistently moist for the first few weeks while roots make contact with surrounding soil.
Spring Care for Perennials Already in the Ground
Early spring, once the ground has thawed, is the right time to cut back any perennial foliage left standing over winter, divide overgrown clumps before they leaf out fully, and topdress beds with an inch of compost. Resist fertilizing too early or too heavily — a flush of soft, fast growth right before a late frost is more vulnerable to cold damage than growth that comes on at a normal pace.
Bridging Spring Into Summer
The tricky stretch in a lot of gardens is the gap after peony finishes and before summer perennials like coneflower and black-eyed Susan hit their stride. Coral bells' foliage helps carry visual interest through that gap even when it's not in bloom, and planning your bed so summer bloomers are already up and budding by the time peony fades avoids the flat, empty look that shows up in beds planted around a single spring showpiece.
Frequently Asked Questions
Why didn't my peony bloom this spring?
The most common cause is planting depth — peony crowns planted more than an inch or two below the soil surface often produce healthy foliage but few or no flowers. Other causes include too much shade (peony needs at least six hours of direct sun) and a plant that's still too young; a newly divided or transplanted peony can take two to three years to bloom well again.
Is it safe to plant perennials right after the last frost date?
Generally yes for hardy perennials, since they're bred to tolerate your zone's winter — a late light frost after planting won't kill an established perennial type, though very tender new growth can occasionally get nipped. If a hard freeze is forecast right after planting, a layer of mulch or a frost cloth overnight is cheap insurance.
