Clematis macropetala

Clematis macropetala is an ornamental vine known for its ability to clamber over structures and fences with ease, thanks to its climbing habit. Dramatic, bell-shaped flowers with a cascade of petal-like tepals, usually double or semi-double, burst forth in spring, exhibiting a range of hues from lavender to deep blue. This hardy perennial thrives in well-drained soil, preferring a spot with plenty of sunlight to partial shade, where it can reach up to 2-3 meters. Its charming flower display is often accompanied by feathery seed heads, adding texture to gardens well into autumn.

Water: Clematis macropetala prefers balanced moisture levels and requires weekly watering. It is not drought-tolerant and loses leaves during the dry season to conserve water. Clematis macropetala can thrive in containers, providing better control over its water supply.

Fertilize: Fertilizer for clematis macropetala should match its size. Use nitrogen after flowering, phosphate from bud appearance to bloom, and potassium consistently. Apply small amounts of diluted fertilizer. During dormancy, add organic fertilizer and compost to boost nutrients and protect roots from frost.

Pruning: Clematis macropetala should be pruned before flowering or during late winter to early spring. Remove weak branches to avoid nutrient loss. Heavy pruning revitalizes growth, while limiting summer pruning promotes leaf retention. Aim to keep half of the thick branches for a longer blooming season and increased flowers.
