What Should You Plant in September? An Overview of Hardy Perennials for the Fall


August has come and gone, and it’s time to start thinking about fall planting. The days are still warm but the nights are starting to cool down, so now is the time to start planning what you’ll plant next season. In this blog post, we’ll look at some of the best perennials for fall planting across different climates so that you can be sure you’re planting the right plants in your area during this season.

Arctic and Alpine Plants

These are some of the hardest plants that you can grow, and one of the best ways to enjoy them is to bring a cutting from your greenhouse or garden into your home. When it comes to growing plants indoors, be sure that they have enough light to stay healthy and happy. If you put them in a sunny window, make sure they get at least six hours of direct sunlight every day.

When growing arctic plants outdoors, prepare for winter by mulching around them with straw or leaves. This will help insulate the soil from freezing temperatures and keep the roots warm enough through cold spells so that they don’t freeze solid when temps drop below freezing point!

Coastal Plants

There are many plants that will thrive in coastal areas. This is because they tend to have the following characteristics:

  • Salt spray tolerance – Plants that can withstand salt spray and high winds are great for coastal areas. Beach roses are a good example of this, as are some other species, such as pines and junipers.
  • Heat and humidity tolerance – If you live in a humid climate, your garden will benefit from heat-tolerant perennials that can tolerate high temperatures without wilting or losing their leaves prematurely each year. Star magnolia trees make excellent additions to any garden, but they may not be the best option for those looking for something smaller!

Desert Plants

When it comes to desert plants, you should be careful about the conditions you choose for your garden. If a plant is not able to withstand heat and dry conditions, it will likely die in a desert climate. There are many options for different types of deserts including:

  • Hot deserts have an average high temperature of over 100 degrees Fahrenheit (37 degrees Celsius).
  • Warm deserts have temperatures that vary between 86 and 106 degrees Fahrenheit (30 and 41 degrees Celsius).
  • Temperate deserts can be found in certain mountainous areas with cooler temperatures averaging between 50-70 degrees Fahrenheit (10-21 degrees Celsius). Some examples include the Sonoran Desert in Arizona or the Mojave Desert in California which gets very hot during the day but cools down significantly at night due to its elevation above sea level.

Bog Garden Plants

Bog plants are ideal for moist, low-light conditions. They include:

  • Bog rosemary (Andromeda polifolia)
  • Purple swamp iris (Iris virginica)
  • Fothergilla gardenii (Fothergilla major)

Mountain Plants

  • Mountain plants are adapted to harsh conditions and therefore often short, compact and hardy.
  • Mountain plants often remain evergreen throughout the year, even during winter months.
  • Most mountain plants have attractive flowers or foliage.

Rainforest Plants

Rainforest plants are tropical plants that cannot withstand the cold. They require tropical conditions year-round and are grown in greenhouses, containers, or the ground. Because they’re so delicate, they need to be constantly monitored during their growing season to ensure they’re getting enough sunlight and water.

Rainforest plants include:

  • Bromeliads (aka airplants)
  • Anthuriums (aka anthuriums or flamingo flowers)
  • Orchids
