Identifying a Vine with Orange-Red Seed Pods

A reader described a 10–12 ft vine with green tennis-ball-sized pods that turn orange, then split to reveal bright red interiors with black gourd-like seeds. The owner called it "Korean vine."

Top Candidates

1. Chinese Bitter Cucumber (Momordica cochinchinensis): Matches perfectly—spiny rind (sometimes smooth), orange-red pulp, black seeds.
2. Blue Passionflower (Passiflora caerulea): Similar pod, but usually more oval; seeds embedded in juicy arils.

Next Steps

Examine **leaves** (shape, lobes), **flowers** (if any), and **smell** of crushed fruit. These details confirm the ID. Photos attached in original show both species for comparison.
