About plant names...
I prefer the name butter and eggs for this attractive plant—the colors are right. This species of
toadflax is native to most of Europe and part of Asia. It was introduced to North America
as an ornamental in the mid 1800s,
and it is now common, or even invasive.
Identification: Plants reach 1-3′ (30-91 cm) in height.
Groups of flowers appear on a stalk. Each flower is about 1″ (2.5 cm) long, pale yellow
with an orange spot. Leaves are numerous, narrow, shaped like grass blades, ¾-4″ (2-10 cm)
long × 1/32-⅛″ (1-5 mm) wide. Flower shape and color is the most obvious identifying
characteristic.
