Prof. Martin Thorne, Ph.D.Window box plants that tolerate shade thrive in areas with partial shade. Ferns offer a lush feel while begonias provide blooms for almost all seasons. Hostas supply unique leaf patterns and caladiums bring bright leaf color. All of these options need about 2-3 hours of filtered light.
Foliage Focused
- Ferns: Delicate fronds creating feathery textures
- Hostas: Bold leaves with variegated patterns
- Heuchera: Color-changing leaves in purple/silver tones
Continuous Bloomers
- Begonias: Wax varieties flowering all season
- Torenia: Trailing blooms thriving in deep shade
- Impatiens: Bright flowers needing minimal light
Colorful Accents
- Caladiums: Heart-shaped leaves with pink/red veins
- Coleus: Vibrant patterns without flowering
- Ajuga: Bronze foliage with spring blooms
Create layered displays to use height differences. Taller ferns can be at the back center, medium hostas can be at the left front center, and trailing ivy can be used as filler. Mix textures, such as feathery astilbe with thick caladium leaves. Use color contrasts, such as silver heuchera in the foreground with purple ajuga in the background.
It's important to manage moisture for shade plants. Apply water when the top of the soil feels dry to the touch. Do not let the soil become sodden. Use a moisture-retaining potting mix containing extra peat moss. Set up self-watering reservoirs to maintain hydration during dry spells.
Seasonal adaptations provide interest throughout the year. Plant spring bulbs, such as daffodils, under hostas. When summer impatiens die out, replace them with ornamental kale for fall. Protect the caladium tubers from frost in the winter by storing them in peat moss.
Soil requirements are different from those of sun plants. Use an acidic mix with increased organic matter for ferns. Add perlite to begonia soil to improve drainage. Test the soil pH annually; maintain a pH level between 5.5 and 6.5 for optimal nutrient uptake.
