Give Your Perennials the Support They Deserve

The Medium Corten Steel Plant Support Frame is expertly designed for gardeners who want their peonies, delphiniums, and other tall perennials to stand tall and blossom beautifully. Crafted from robust 5mm-thick Corten steel, this frame develops a unique rust effect that not only adds vintage appeal but also protects the metal from further corrosion.

Why Choose Corten Steel?

• Durability: The rusted patina acts as a shield against harsh weather, ensuring your frame lasts through many seasons.
• Low Maintenance: Unlike painted supports, this frame requires no upkeep—simply install and let nature do the rest.
• Aesthetic Appeal: The earthy tones of the rust effect blend seamlessly into garden borders and cottage-style planting schemes.

Perfect for Peonies & More

• Mature Size: Medium frame measures 63 x 34cm—ideal for supporting medium-sized perennials at full bloom.
• Flowering Period: Use to support peonies from spring through summer, preventing stems from drooping under large blossoms.
• Planting Location: Place in borders, beds, or containers wherever upright support is needed.

Caring for Your Plant Frame

• Installation: Position the frame around young shoots in early spring before rapid growth begins.
• Maintenance: No painting or sealing required—let the natural rust develop for ongoing protection.
• Seasonal Care: Leave in place year-round or lift after flowering to store if desired.

Companion Planting & Design Tips

• Pair with: Other upright perennials like delphiniums, lupins, or dahlias needing structural support.
• Create layers: Use multiple frames at different heights to stagger blooms and add visual interest to mixed borders.
