A young hazel tree or a small hazel shoot, primarily a dialectal or regional term.
Formed from 'hazel' with the diminutive suffix -ling, indicating something small or young; primarily found in British regional dialects.
Haspling is a perfect example of how English dialects create tiny words for specific things—in rural areas, farmers and foresters needed a quick word for baby hazel saplings, so they just added -ling and it stuck. These regional words are disappearing fast as English becomes more standardized.
