This is the standard wording explaining that flowers are subject to seasonal availability and may occasionally need to be substituted for a similar variety.
Go to Dashboard > Products > Product Settings and find the Substitution Policy section.
This text typically appears on product pages alongside the de script ion, setting expectations before a customer orders rather than after a substitution has already happened.
A clear substitution policy reduces complaints and refund requests when a specific flower is genuinely unavailable, since customers have already agreed to the possibility before ordering.
