Lydia is a product of Tecoma breeding project of George Hull in Phoenix. She is indeed a beautiful everbloomer that can be expected to be in bloom from very early spring until frost.
Compared to other yellow Tecomas, Lydia is a very compact, dwarf shrub, flowers are clear, soft lemon-yellow color with white throat. Unlike traditional varieties, it is a sterile hybrid that doesn't produce messy seeds that most tecomas do.
Tecomas do appreciate a bit of extra fertilizer so monthly during the growing season, a small application will induce more new growth and flowering.
