Thirty years of selection. Direct source relationships. Documented results.
Engei-Ten exists because thirty years of growing Adenium, Pachypodium, Plumeria, and Euphorbia milii in Zone 6 — the most demanding climate in which these genera are successfully cultivated at this scale — produces something that cannot be purchased: accumulated knowledge of what works, what fails, and what the genetics behind a specimen actually determine. That knowledge is what Engei-Ten offers. The specimens are its evidence.
Direct relationships with cultivators in Thailand and Madagascar, established over decades of correspondence, visits, and selection. Not wholesale accounts. Not catalog imports. Relationships built on mutual respect for the standard of the work.
The Thai Adenium and Euphorbia milii collector markets are among the most sophisticated botanical cultivation cultures in the world. Access to their finest genetics is not available through catalogs. It is available through relationships that take time to establish and maintain.
Selection for Engei-Ten's collection is governed by criteria that accumulate over years of observation. Caudex architecture in Adenium. Proportional form in Pachypodium. Fragrance complexity and bloom stability in Plumeria. Bloom architecture and color stability in Thai Euphorbia milii.
These are the criteria of the serious collector applied to every specimen offered. Not every plant that passes through thirty years of cultivation reaches the collection. Most do not. The collection reflects what did.
30+ years growing Adenium, Pachypodium, Plumeria, and Euphorbia milii in Zone 6, Northern Kentucky — since 1994.
