Medium 18" - Plant 14" apart. zone 3-9 Vigorous plant habit, and large golden flowers. Especially free flowering - continuously in bloom from early summer right into fall. Makes a good cut flower with its unusual narrow tapered foliage. They spread readily and can be used in a naturalized planting. While they attract butterflies, they are deer resistant.

Needs a nice sunny well drained spot. Very easy to grow. Deadhead with hedge shears after flowering to freshen foliage. Spreads underground, so division every 2-3 may be necessary to contain girth.
