Buying Guide
What to consider when buying blue sweet pea options:

- Height and spread: Tall climbing varieties suit arches and trellises; compact mixes fit containers and small fences.
- Fragrance and bloom quality: English heirloom varieties like Lord Nelson offer fragrance; artificial stems provide no scent.
- Color stability: Seed mixes may yield multiple blues or bi-colors; select a pure blue if color consistency matters.
- 用途: For bouquets and cutting gardens, choose long-stem or mammoth varieties; for decor, consider artificial stems for longevity.
