Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.

CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.

About Purple Dragon

In public strain data, Purple Dragon is classed as an indica. Its listed parents are Purple Urkle and Blue Dragon.

How strong is Purple Dragon?

Public listings give Purple Dragon a THC level of 13%, which is in the lower third of our dataset. Compared with all strains in our research dataset that have their own THC figure, it is higher than roughly 5% of them. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.

Purple Dragon aroma, flavor and terpenes

Its most-reported flavor notes are grape and sweet. Its top listed terpenes are limonene (citrus), caryophyllene (peppery, spicy) and pinene (pine). Limonene is the lead terpene for about 21% of the high-confidence strains in our dataset, so it is a less common lead. Terpenes shape smell and taste; their levels change from batch to batch.
