FUN FACT: These elegant lacecap flowerheads attract a wide variety of pollinators, which are often found exploring the cluster of deep violet fertile florets at the center. Their vivid color stands out beautifully against the ring of showy sterile white florets. This cultivar commemorates Takiya Kawakami (1871–1915), a Japanese botanist for the Government of Formosa, now Taiwan.
