  • Blue Star 'Blue Ice': A durable but beautiful addition to your garden. It’s the perfect landscape plant that changes color to match the season. In the spring and summer, it has dark green foliage with dark lavender-blue flowers. By the fall and winter seasons, it has a lovely golden-yellow hue.
  • Chives Garlic: Add deeper flavor profiles to your food without letting it get too overpowering with a handful of fresh chives to sprinkle on your plate. It’s a popular addition to any herb garden, as they’re quick to regrow and are fairly easy to maintain.
  • Fennel “Green”: A popular herb in our store that can survive the warm to hotter zones, fennel has eye-catching foliage but works just as well as an herb for your soups and stews. Add it to your salmon dish or steep it in tea for a calming and diuretic effect. In the summer, it produces beautiful yellow flowers and attracts pollinators to your garden.
  • Cuban Oregano: Also known as the Spanish Thyme or Mexican Mint, Cuban Oregano has a delectable scent stronger than its Greek variant. As a semi-tropical plant, It prefers the hotter climate but is best kept away from direct sunlight. 

    • What Is Zone 9?

    Factors such as geography and topography can affect how well some plants can survive in certain areas throughout the United States. With varying US temperatures, the United States Department of Agriculture (USDA) established the USDA Plant Hardiness Zone Map. This map helps farmers, gardeners, and people interested in growing plants determine their location’s zone and which plants can survive in their local climate. 

    The USDA Plant Hardiness Zone Map divides the US into 13 growing zones. Each zone entails a 10-degree temperature range based on their minimum winter temperature. This means that plants that thrive in Zone 1 do better in harsh, freezing cold conditions than plants in Zone 13, which barely see cold weather. 

    Zone 9 is the start of the hotter summer zones as it features longer and hotter summers and winters that barely go under freezing. Plants in Zone 9 experience average minimum winter temperatures ranging from 20°F to 30°F (-6.6°C to -1.1°C). Zone 9 can be divided into:
    • Zone 9a: 20°F to 25°F (-6.6°C to -3.8°C)
    • Zone 9b: 25°F to 30°F (-3.8°C to -1.1°C)
    Because of their varying topography, climate, and location, one state can have multiple zones. States that have Zone 9 areas on their map include:
      • Alabama
      • Arizona
      • California
      • Florida
      • Georgia
      • Hawaii 
      • Louisiana
      • Mississippi
      • Nevada
      • New Mexico
      • Oregon
      • South Carolina 
      • Texas
      • Utah
      • Washington
    Zone 9 plants are best planted in early February to catch the growing season that lasts from February to December. Plants in Zone 9 should be tolerant of hotter temperatures. You may want to consider cultivating separate winter and summer gardens to maximize your space.
