Top 5 Summer‑Flowering Bulbs for Vibrant Borders

As spring teases with false warmth, plan ahead for a spectacular summer display. Here are five bulbs to plant for season‑long color.

1. Acidanthera (Peacock Orchid)

White, gladiolus‑like blooms with a sweet scent. Plant in rich, sun‑warmed soil in May or later, 4–6″ apart and 4″ deep. Lift in autumn; store cool and dry to prevent rot.

2. Allium giganteum

Huge mauve globes on sturdy stems. Needs well‑drained, gritty, nutrient‑rich soil. Plant 7″ deep and apart in early spring or divide offsets in autumn. Ideal for cold‑frame propagation.

3. Convallaria (Lily of the Valley)

Fragrant, bell‑shaped flowers on clumping foliage. Thrives in humus‑rich, chalky, well‑drained soil. Space 7″ apart for a ground‑cover carpet. Low maintenance once established.

4. Gladiolus

Bold, colorful spikes made famous by Dame Edna. Plant 4–5″ deep after last frost; mulch for insulation. Lift in autumn unless in mild climates.

5. Tigridia (Mexican Shell Flower)

Exotic, speckled blooms in full sun, sandy fertile soil, 4″ deep. Tender—lift after flowering, store in dry sand at ~10°C. Replant after frost danger passes.
