Easiest Flowers and Perennials for Beginners

Easy annuals you can sow straight into the ground

The simplest way to get flowers fast is to skip transplants and sow seed directly. Iowa State's list of annuals that can be direct-seeded into the garden includes marigold, zinnia, cosmos, sunflower, nasturtium, and sweet alyssum — no seed-starting setup required. And they don't make you wait: Iowa State notes fast-growing species can be ready to flower within six or seven weeks of sowing.

Timing is the one thing to get right. Most of these are warm-season flowers best sown after the soil warms, but nasturtium is a cool-season annual Iowa State says can be sown three to four weeks before the last frost — so match the flower to the moment in spring. For a whole bed of easy color, our guides to a wildflower meadow and a cut-flower garden build on the same plants.

Perennials that come back and ask for little

Perennials are the long game, and the easy ones pay off for years. Iowa State notes these long-lived plants return each year, often growing larger and better with time, and many tolerate a wide range of soil types and weather. Their named easy-to-grow list is a solid beginner shopping list: hosta, daylily, salvia, purple coneflower, stonecrop (sedum), catmint, yarrow, thread-leaf coreopsis, Shasta daisy, and iris.

A few stand out for sheer toughness. Iowa State credits daylily and yarrow with toughness and drought tolerance, calls sedum low-maintenance with late-season interest, praises coreopsis for a long bloom and minimal care, and calls hosta extremely durable and long-lived (and a rare easy pick for shade). See how to grow coneflowers and perennial salvia for two of the most bulletproof.

Why these plants forgive beginners

The thread connecting both lists is tolerance. The annuals germinate readily, grow fast, and bloom quickly from a direct sowing; the perennials survive a wide range of soils and weather, resist drought once established, and return under their own steam. That's exactly the margin for error a new gardener needs.

Play to that forgiveness: give them decent sun, don't overwater, and let the perennials settle in their first year before expecting a show. Combine a few fast annuals for immediate color with a backbone of tough perennials, and you get a bed that looks good this season and better every season after — the design idea behind our guide to a layered flower border.
