9 Bulbs You Need to Pre-Order Now for a Show-Stopping Summer Garden

When it comes to spring-planted bulbs and tubers, the best time to buy is often much earlier than you’d expect. Many standout varieties are grown in limited quantities and tend to sell out quickly, which means waiting until planting season can leave you with fewer — and far less exciting — options. Pre-ordering now is the best way to secure the bulbs you actually want and ensure your garden delivers bold, beautiful results.

Enter Eden Brothers, a favorite brand amongst Gardening Know How experts and your one-stop shop for unique varieties of the most popular bulbs and tubers. Don't fret about timing, as pre-ordered bulbs are packed and shipped at the optimal time for your growing zone, so they arrive when your garden is ready for them.

I’ve rounded up nine spring-planted bulbs and tubers worth pre-ordering now from Eden Brothers — all popular picks that are likely to sell out — so you can lock in your favorites and enjoy a garden that turns heads come late spring and summer.

1. Begonias

Begonias are a go-to for gardeners who want nonstop color with minimal fuss. They thrive in containers, hanging baskets, and shadier spots where other blooms struggle, making them incredibly versatile. If you’re looking for reliable impact from spring through summer, begonias are an easy win.

2. Calla Lilies

Calla lilies are a favorite for gardeners who love clean lines and elegant design. Their sculptural blooms and rich color palette make them perfect for both modern landscapes and romantic cottage gardens. Pre-ordering now is the best way to secure unique shades.

3. Canna Lilies

If bold, tropical drama is what you’re after, canna lilies deliver in a big way. Known for their oversized foliage and vibrant, exotic blooms, cannas instantly make gardens feel lush and intentional. They’re especially popular for adding height and color to beds, borders, and containers — and pre-ordering ensures access to standout varieties before they sell out.

4. Dahlias

If there’s just one plant you pre-order this season, make it dahlias. From moody, dramatic gardens to soft pastel cottagecore looks, there’s a dahlia for every style. With everything from tidy pom-pom blooms to jaw-dropping dinner-plate flowers, it’s no surprise dahlias are among the most popular tubers year after year. Eden Brothers offers a whopping 119 varieties of dahlias — here are some of their bestsellers.

5. Daylilies

Daylilies are the definition of plant-once, enjoy-for-years gardening. These hardy perennials return year after year with cheerful blooms and very little maintenance required. With countless colors and forms available, they’re perfect for filling borders and creating a polished, full look.

6. Gladiolus

Gladiolus are all about height and drama. Their tall flower spikes add instant structure to garden beds and make stunning cut flowers for bold arrangements. Pre-ordering ensures access to the most eye-catching colors before they’re gone.

7. Peonies

Peonies are the ultimate garden investment. Their lush, fragrant blooms are beloved in gardens and bouquets alike, and once established, they can thrive for decades. Pre-ordering is key if you want the best varieties — these sell out fast for a reason.

8. Ranunculus

Ranunculus bring serious florist energy to the garden. Their tightly layered, rose-like blooms look straight out of a bouquet and are especially prized for cutting gardens. If you want spring flowers that feel elevated and intentional, ranunculus are a must.

9. Oriental Poppies (Papaver Orientale)

Okay, technically oriental poppies are not bulbs or tubers, but rather bare roots. I couldn't resist including them in this list — they're simply too stunning not to. Their large, papery blooms and vivid colors create unforgettable displays in late spring and early summer. They may bloom briefly, but the impact is absolutely worth it.
