Bulb Size
Bulb size refers to the corm's circumference in centimetres — a measure of the bulb's maturity, not the flower.
4/5 — the standard commercial top-size grade. Produces the most blooms per corm and is our recommended choice for most growers.
5/7 — a larger, premium grade. More established corms for even stronger, earlier flowering.
Substitutions: availability from Italy can vary by size. If a substitution is needed, we'll contact you before despatch and adjust any price difference.
