Growth adapts and grows quickly under ideal conditions and is three-sided with tiny thorns that are very typical looking of Hylocereus guatemalensis. Single cuttings have reached over six feet growing in just one summer. Due to this aggressive growth, heavy pruning is recommended. This variety is robust but will sunburn if exposed for long periods, though it rarely sustains permanent damage.
The flowers and flower buds are very similar to other H. guatemalensis varieties, with a white and yellow appearance typically 14 inches across. Flower open to fruit is 30 days in South Louisiana. This variety is self-fertile, so no pollinator is needed.
The exterior skin is light green and pink hues, with the green turning pinkish-red as the bright purple flesh becomes ripe. Thomson G1 produces a sweet and delicious medium to large fruit ranging from three-quarters to one and a half pounds. Fruits have an average brix rating of 16, with some of the larger fruit having a 19 rating. While its lack of sun tolerance properties is negative, the good-tasting attractive fruit from self-fertile flowers makes it worth the trouble.
