Thomson G1 Dragon Fruit or Thomson Guatemalan – 1 Dragon Fruit variety comes from the genus Hylocereus and the species guatemalensis. This variety is a clone that was originally collected by Paul Thomson. This plant is self-fertile so no pollinator is needed. It produces a sweet and delicious medium to large fruit ranging from three-quarters to one and a half pounds. Stems are strong but will sunburn, though rarely sustain permanent damage. Like many of the Guatemalan varieties blooms early and produces plenty of fruit well into the late season. While its lack of sun tolerance properties is negative, the good-tasting attractive fruit from self-fertile flowers makes it worth the trouble. To back this up, the fruit has an average brix rating of 16 with some of the larger fruit having a 19 rating. Spicy Exotics collected this variety from a grower in California.
