Gardening is one of the most rewarding hobbies, but knowing what to plant—and when—can be a challenge. One of the most important things to consider when choosing plants is your USDA Plant Hardiness Zone. These zones are based on average annual minimum winter temperatures and help determine what plants are most likely to thrive in your region. Whether you're planting a flower-filled landscape, a productive vegetable garden, or a lush shade oasis, selecting zone-appropriate plants can make all the difference.
In this guide, we’ve gathered insights from experienced gardeners across USDA Zones 6, 8a, 9a, and 9b. These plant enthusiasts share their top recommendations for flowers, perennials, fruits, vegetables, and more—along with helpful advice for making the most of your growing conditions. Whether you're gardening in a cold-climate zone like 5b, a temperate Zone 6, or a hot, dry Zone 9b, this list will help you pick the best plants for your region and maximize your garden’s potential.

Zone 9a: Mild Winters, Intense Summers
All the way west in Zone 9a, Northern California, Robbie McMenomey of the YouTube channel @visitourgarden describes his climate as a gardener’s dream, with a year-round growing season. However, he’s quick to caution that the full sun in this zone can be intense. "I have to be really mindful of when plant tags say full sun— not many things love the extreme sun," Robbie explains. He finds success in lavender, salvias, ornamental grasses, sunflowers, and zinnias in sunnier parts of his garden, but notes that partial sun areas are where her plants truly thrive. "Specifically, morning sun and afternoon shade," he emphasizes.
Robbie also experiments beyond his zone by using microclimates. This means growing plants in specific garden spots that mimic the conditions of cooler zones. "Brunnera in the spring is one of my favorites and peonies in summer beat everything else," he says. By carefully choosing spots with morning light and shelter from harsh afternoon rays, he’s able to expand her plant palette considerably.

Zone 9b: Hot, Dry, and Full of Surprises
Janey Santos, of the YouTube channel @digplantwaterrepeat, who gardens in Zone 9b in Northern California, echoes the joys and challenges of a Mediterranean climate. "This is different than zone 9 in the South which is hot and humid!" she explains. Janey’s garden must withstand long, dry summers and infrequent but intense winter rain.
Citrus trees thrive in this environment, and her orange trees are a family favorite. "Every January, my family and I enjoy buckets of fresh oranges... The scent of orange blossoms in the spring is one of my favorite scents in the world."
Perennials play a huge role in Janey’s garden design. "Playin’ the Blues Salvia from Proven Winners can’t be beat," she says. The vibrant purple flowers appear early in spring and continue blooming through December. Lamb’s Ear is another staple, especially the variety 'Helen Von Stein,' which has larger, velvety leaves. "They remind me of our pet bunny’s ears!" she adds.
She also champions begonias, specifically the Surefire Rose Begonia, which thrives in both full shade and full sun. This makes it ideal for garden beds that change light exposure throughout the seasons. For vegetables, artichokes top her list. "Not only are they incredibly delicious, but the structure of the plant is absolutely stunning," Janey says. If left to bloom, artichokes reward gardeners with electric purple flowers.
To brighten up the winter months, Janey turns to Camellia Japonica 'Debutante,' a January and February bloomer with frilly pink flowers that offer a much-needed splash of color.
