Bulbs that need lifting over winter
The other half of 'bulbs you plant once', and the half people find out about by losing the plant. Authored expecting to fail on too-few-results — the catalogue holds two — and recorded so the gap is a named work item rather than a silence.
How this list was built
Generated from the catalogue by the same engine that powers What can I grow? — 6 of the 18 bulbs, corms, rhizomes and tubers qualify. It is published because it names a question people ask, returns enough plants to be useful, does not return most of the group it is about, and rests on fields that are actually populated. Lists that fail any of those are on the coverage page instead.

This is one cut through bulbs, corms, rhizomes and tubers, which compares every one of them on foliage, size and container suitability — including the ones this list rules out, and why.
