Trichocereus hybrid 'First Light' was introduced by Mark Dimmitt. Hybrids of Trychocereus and Echinopsis in a narrow sense are becoming more popular among collectors. They are easy to grow, and flowers are hard to beat.
These hybrids need to be propagated by cuttings, as seed-grown plants will not inherit the parent's character. At the other hand, crossing different plants one gets a large veriety of forms, and with high possibility of other interesting specimens appearing. Everyone could try his creator's hand, since rising Echinopsis and Trichos from seed is about as easy as it gets with Cactaceae. And nothing is like waiting to see the first flower of your own cacti, of a kind none have seen yet.
