Zone 8 runs in a curve all across the United States reaching from Washington, down to Arizona, then curving around to North Carolina. While these areas do have frost, they have milder weather that leads to healthy growing seasons. Portland, Salem, Ridgecrest, Austin, Dallas, Seattle and Tallahassee are just a few of the cities that enjoy this mild weather. 

Zone 8 has two subzones, Zone 8a and Zone 8b. These Zones are differentiated by their minimum average winter temperature of 10 degrees F to 20 degrees F. Respectively, Zone 8a is 10 degrees F to 15 degrees F, while Zone 8b is 15 degrees F to 20 degrees F. This Zone is the most common warm Zone in the US! Using tricks like mulch can help you extend your long growing season even a bit further, but you will have to consider both the hot summer months and the frost season.

Which Plants Grow Well in Zone 8?

Due to the warmer temperatures, many fruit trees love Zone 8! Along with these, there are many beautiful flowers and plants that love the warm, sunny summers. When thinking about what plants to add to your garden and indoor collections, consider overwintering some plants that are maybe less hardy to the frost, but can easily handle the warmer seasons. Some great examples of flowering plants to grow in Zone 8 are:

For foliage and greenery that loves Zone 8, try:

  • Split Leaf Philodendron (Monstera Deliciosa): More commonly called the Swiss Cheese Plant due to its notched leaves, it has gained popularity due to its use in interior design photography. The large plant brings trendy jungle vibes into your space and will spread out to liven up a large area. These plants can be brought outside in morning, partial shade as long as the night temperatures stay above 50 degrees F. While indoors, it likes bright to medium indirect light for at least 6 hours a day. Beyond those requirements, this is an extremely easy plant to take care of, though it does like a higher humidity so spritz it occasionally! 
  • Lady Palm (Rhapis Excelsa): Often seen as a houseplant, the Lady Palm with its fan-shaped fronds does well outside in Zone 8b on patios as long as the freeze doesn’t get too cold! When outside, the Lady Palm doesn’t like direct light, keep it in full shade on a patio! It can survive outside in temperatures down to 20-30 degrees F, but for continual healthy growth you can bring it inside when nights start hitting 55 degrees F. 

Gardening Tips

  • Which Plants Grow Best In Zone 8?

    Zone 8 is one of the most common Zones within the United States - that means more than ever it is essential to consider your individual climate. For example, Seattle is much more likely to have temperate weather in comparison to a drier area like Austin or Dallas. Usually the last freeze date for Zone 8 is March 15th, and the first freeze date is November 15th. Check your specific area for more accurate dates, as this will vary from region to region. Remember that the general rule is to start vegetables indoors about 6-8 weeks before the last frost date!

  • When Should I Plant My Garden in Zone 8?

    Winter gardens are a great option in Zone 8 that some other Zones don’t get to take advantage of! You can plant cool-loving crops like broccoli and spinach in October while your soil is still warm. Raised beds and cold frames make this even more possible, as do protective measures such as mulch. In the hotter months, consider drip water irrigation if there is little rain in your region, or even shade clothes during those harsher summer months!
