Combine a rustic wooden arch with climbing vines to create a modern minimalist garden. Choose vines like ivy or clematis to cover the arch and create a simple yet elegant display. Surround the arch with clean lines and minimalistic elements like concrete planters, gravel pathways, and geometric shapes. Use a limited color palette of greens, whites, and neutrals to maintain the minimalist aesthetic. The rustic wooden arch will add a touch of warmth and natural beauty to your modern garden.
