Pereskia aculeata is a scrambling shrub in the family Cactaceae. Common names include Barbados gooseberry, blade-apple cactus, leaf cactus, rose cactus, and lemonvine. It is native to tropical America

The term "lemon vine" is not commonly used to refer to a specific plant. It may be a regional or colloquial name for a plant, or it could be a term used to describe a vine-like plant with lemon-scented foliage or lemon-like fruits. Without more specific information, it is difficult to provide a precise answer.

However, there are a few plants that are often associated with lemon-scented foliage or lemon-like fruits. Here are a couple of possibilities:

1. Lemon Verbena (Aloysia citrodora): Lemon verbena is a perennial shrub that is known for its strongly scented leaves, which have a lemon-like fragrance. It is commonly used in herbal teas, cooking, and potpourri. While lemon verbena is not a vine, it is a popular choice for its lemon-scented properties.

2. Lemon Balm (Melissa officinalis): Lemon balm is a perennial herb in the mint family that has a lemon-like aroma. It is often used for culinary purposes, such as flavoring teas, desserts, and salads. Lemon balm is not a vine either but is known for its lemon scent.
