A: The three most popular Lychee varieties are: Brewster, Mauritius, and Sweetheart (sometimes referred to as Hak Ip). Brewster and Mauritius are the most reliable producers and are commonly used commercially, while Sweetheart is more of a backyard specialty. Although it produces fewer fruits, the fruit are significantly larger than other varieties.

Brewster: Medium to large, round fruit and a sweet, slightly tart flavor, Brewster is highly productive and ideal for fresh eating.

Mauritius: Medium to large, round fruit with thick skin. It has a sweet, delicate flavor and is one of the earliest varieties to ripen.
Choose Brewster or Mauritius if you want a reliable producer with an average fruit size.

Sweetheart: True to its name, Sweetheart is prized for its exceptional sweetness. It has the largest fruit of all varieties, with a thick rind and juicy, flavorful interior.
Some growers consider Hak Ip to be just another trade name for Sweetheart, although it is sometimes marketed as a separate variety.
Opt for Sweetheart if you prefer larger fruit but don't mind a smaller harvest.

Keep in mind that Lychee trees typically produce every other year, with heavy crop years alternating with low production years or no fruit at all.
