Best Spring Blooming Bulbs for Warm Climates

By | December 17, 2020

Who doesn’t want to enjoy the colors and scents of spring in their garden? In spring most gardens in the United States will bloom with colorful tulips, daffodils, and hyacinths. However, not all gardens are able to enjoy the same flowers as others due to regional climate differences.

Fall planted bulbs like tulips and hyacinths require specific temperatures in order to produce a flower bud. Gardeners in warm areas like southern states and coastal areas usually don’t have consistently cold enough temperatures for the bulbs to form a bud. This does not mean that gardeners in warm climates can’t plant bulbs in fall or early winter for spring blooms. It means they have to select the bulbs that don’t require cold temperatures for a bud to form. For those lucky enough to live in an area with warm winters this list of the best bulbs for warm climates will help determine what to plant in late fall and winter.

Allium Blend

Big Impact Allium

The flower shape and size aren’t the only factors of the different daffodil divisions, what climates they grow in is another important difference. Daffodils of the Tazetta and Jonquil divisions perform the best in warm climates. However, all other classifications of daffodils will grow well in the majority of the United States up to hardiness zone 8 or 9 depending on the specific variety with the exception of the very warmest areas such as southern Florida.

Planting Flower Bulbs in Warm Climates

While spring-planted bulbs are the shining stars for warm areas it does not mean fall-planted bulbs should be left out. Gardeners in warm areas such as Texas, Arizona, Florida, California, and the southeastern United States can plant bulbs and perennials later in fall and into early winter. Fall planted bulbs can be planted as late as mid-January in warm hardiness zones for blooms in a couple of months. Bare root perennials can also be planted in late fall or early winter in mild areas for the next summer of blooms.
