Thomson G2 Dragonfruit is a Guatemalan variety of climbing cactus that produces impressively large fruits weighing 1.0 to 2.0 pounds with notably sweet flavor. This is a clone originally collected by Paul Thomson, selected for its vigorous growth and abundant fruit production that extends well into late season. It thrives in full sun and handles drought naturally, making it a resilient choice for warm-climate gardeners seeking a dramatic fruiting vine.

Large, sweet fruits that tip the scales at 1.0 to 2.0 pounds set Thomson G2 apart from lighter-fruiting dragonfruit varieties. The strong stems support heavy yields, though they can sunburn in extreme heat (rarely causing permanent damage). Its early bloom time and extended fruiting season mean you'll harvest fruit from early production straight through to the end of the growing period, rewarding patience with abundance.
As an edible dragonfruit, Thomson G2 is grown primarily for fresh fruit consumption. The large, sweet fruits can be eaten fresh by scooping the white or pink flesh directly from the skin, used in smoothies and beverages, or incorporated into desserts and fruit salads where their mild sweetness and delicate texture shine.

Harvest dragonfruit when the skin reaches its characteristic bright pink or magenta color and the fruit yields slightly to gentle pressure. The large fruits typically weigh between 1.0 and 2.0 pounds and can be cut from the vine with a sharp knife. Pick fruit in the early morning for best flavor and handle gently to avoid bruising the delicate skin.
As a climbing cactus, Thomson G2 benefits from training and support pruning to encourage horizontal growth along trellises and spread, which improves air circulation and fruit exposure to sunlight. Remove any weak or damaged stems, and thin dense growth in spring before the bloom period to direct energy toward flowering.
