Short answer: Pumpkin is generally allowed in both Śvetāmbara and Digambara Jain practice. The common restriction is on kand-mūl (root/underground vegetables), not on above-ground vegetables like pumpkins.

Why root vegetables are avoided (the basis for many Jains’ choices):

• Root vegetables (potato, onion, garlic, carrot, radish, etc.) are avoided because uprooting the plant harms many life-forms and the roots are seen as containing many subtle lives. This is the Anant-kāy principle shared by both Śvetāmbara and Digambara traditions. Some lists may vary slightly, but the core idea is common. You can read concise guides on root-vegetable avoidance and on which vegetables are considered acceptable.

About pumpkin specifically:

• Pumpkin is an above-ground vegetable/fruit and is typically considered okay, unless a local guru or temple tradition imposes stricter seasonal rules (e.g., during certain holy periods). For practical guidance, many Jains eat pumpkin as part of their regular meals.

Different meanings between traditions:

• There are minor regional or guru-based variations in how strictly some communities observe even above-ground produce during special periods, but the general rule about kand-mool applies to both Śvetāmbara and Digambara. If you want, I can point to guidance specific to a tradition or local temple.
