The Crown-of-Thorns Cancer Myth: A Brief History of Euphorbia Madness in the Philippines I just posted the final scene of my series on Thailand’s Crown of Thorns madness in the 1990s over on my Facebook page.

That really was the 1990s—and the Crown of Thorns (Euphorbia milii) madness is still alive and kicking among rare plant collectors today. But while the craze is thriving in places like the United States, the history of the Euphorbia craze in the...
The Biology of the "Lazy" Crown of Thorns
The reason behind a *Euphorbia milii* (Crown of Thorns) plant shooting straight up as a single, unbranched stalk—refusing to spread out—is actually a "biological battle" between plant hormones and internal energy allocation. Let’s dive into the secrets of plant physiology and discover four brilliant hormone-hacking tricks to wake up dormant buds, encouraging them to sprout branches and form a perfectly lush, bushy shape just the way you want.

How to Get Your Crown of Thorns to Bloom Faster
Not all Crown of Thorns are built to bloom — and that’s the truth most collectors never hear. Even with perfect care, fertilizer, light, and watering cycles, a plant with weak or unknown genetics may never produce the heavy, reliable blooms seen in true Thai hybrids. Blooming is not just about technique; it’s also about DNA.
Many inexpensive Crown of Thorns circulating in the hobby world have never been tested, verified, or even bloomed by the sellers themselves. Some seedlings carry mutations that affect leaf shape, color, or growth — but not necessarily flower performance. A Mexican specimen grown from seed, the "Vino Tinto," is a perfect example: it boasts beautiful, twisted flowers—medium-sized and a deep burgundy hue—but you have to perform a whole "flower dance" to get them to open.
That’s why bloom success comes from two things working together: strong genetics + correct horticultural technique. Once you have both, fast, dense flowering becomes predictable — not a mystery.
