We have been very impressed with the performance of this stunning new Ajuga x bastarda (Ajuga decumbens x Ajuga yesoensis) from the folks at Terra Nova. The plant started its life in Japan and was stabilized by Takuya Izumi, who named it Ajuga 'Hanabi'. Terra Nova took it to Oregon, doubled the chromosomes, and behold, Ajuga 'Sparkler'. The slowly spreading patch is composed of narrow, jagged dark green, deer-resistant leaves with lovely white speckling, reminiscent of a low-bid paint job. Ajuga 'Sparkler' is one of the most distinctive and humidity-loving, non-melting selections we have grown. I still don't understand the x bastarda specific epithet since we know the baby daddy...perhaps they just weren't properly wed. Ajuga flowers attract hummingbirds.
