Refreshing Your Containers for Fall

Fall is here and, at this point in the season, it’s fun to start thinking about the new plants, colors, and textures for your containers so they will offer continued interest through fall, winter, and even into early spring. It’s the perfect time to get new foliage planted in the containers you would like to refresh so there can be nice root growth before frosts come. Usually, we’ll see frosts hit the PNW as early as the end of October.

“Fall and winter containers are of visual interest to me because I enjoy seeing the different textures, shapes, and colors of the foliage without being distracted by a showy blossom. Raindrops and ice on foliage is particularly beautiful! Have you ever seen a dark purple Heuchera outlined in ice?”

Prepare Your Container

Start by cleaning up your summer containers to remove dead, diseased, or damaged foliage. Make sure you pull all of the old root balls of removed plants and have fresh potting soil ready to refresh the existing soil and to plant up new plants. Some of the more popular annual plants you can anticipate needing to remove from your summer container arrangements might be Million Bells, Geraniums, or Coleus. These plants won’t survive as temperatures drop.

Plan Your Design

With these plants removed, you have the opportunity to rearrange the container, fill in the gaps, or store the container over the cooler months and display it again next year. Let’s go ahead and assume you want to keep things interesting and you would like to replant the container. Perennial options can offer a lot of interest from fabulous foliage colors to attention-grabbing textures, though we have a few annual plants to suggest that you can plant up too!

Here are some tips to create an interesting and long-lived design:

Design by Color Palette

Kate, one of our annual plant experts, recommends planning your container arrangements for fall based on a warm or cool color palette. We love that idea, especially in combination with the container design method to create an interesting form, containing a thriller, filler, and spiller. For tips on thriller, filler, spiller container design, see this post for containers in sun, and this post for containers in shade.

Consider these plants if you would like to plant warm colors:

  • Orange Sedge – Carex testacea

  • Apricot Coral Bells – Heuchera villosa

  • Wintergreen – Gaultheria procumbens

  • Rose-Colored Pansies and Violas – Viola spp.

  • Golden Creeping Jenny – Lysimachia nummularia

  • Yellow Variegated Periwinkle – Vinca ‘Illumination’

  • Golden Variegated Sage – Salvia officinalis ‘Iceterina’

  • Mahogany Carpetbugle – Ajuga reptans ‘Mahogany’ and other purple cultivars

  • Golden Thyme – Thymus serpyllum ‘Aureus’ and other yellow cultivars

  • Autumn Brilliance Fern – Dryopteris erythrosora ‘Brilliance’

  • Wilma Goldcrest Cypress - Cupressus macrocarpa ‘Wilma Goldcrest’

Consider these plants if you would like to plant cool colors:

  • Ornamental Cabbage and Kale

  • Blue Fescue - Festuca glauca

  • Blue Oat Grass – Helictotrichon sempervirens

  • Purple Coral Bells – Heuchera cvs.

  • Blue Pansies and Violas – Viola spp.

  • Variegated Ajuga – Ajuga cvs.

  • Green Creeping Jenny – Lysimachia nummularia

  • Periwinkle – Vinca minor

  • Purple Sage – Salvia officinalis ‘Purpurascens’

  • Dusty Miller – Senecio cineraria

  • Himalayan Maidenhair Fern – Adiantum venustum

In mid- to late-spring, when you’re ready to plant up warm-season flowers again, the perennial plants you used in this container can be transplanted into the garden, given to friends, or composted if you don’t have the space. Some may even be able to stay in your container as accents.

 

Design with Bulbs

Another element to think about is if you’d like to add a surprise! Bulbs can offer additional interest as winter is coming to an end, when blooms from bulbs will make their way through what is planted above them to bloom. By layering bulbs underneath your planting, you’ll have continued container excitement in late winter and early spring. Some bulbs to consider planting for late-winter interest may include:

  • Snowdrops – Galanthus nivalis

  • Crocus - Crocus sativus

  • Daffodil – Narcissus spp. and cvs.

  • Tulips – Tulip spp. and cvs.

Remember to include bulb fertilizer at the time of planting to ensure your bulbs have all the nutrients they need to flourish.

Tip: For a quick and easy container arrangement using bulbs, layer the bulbs you’re interested in per the instructions on the packaging, and then plant a carpet of color-coordinating pansies and violas on the surface. The bulbs will poke through in late winter to offer you early spring blooms! See more about this layered bulb container.
