Charming, smallish clumper, (2 ‘ tall x 2’ wide) with glowing buds the color of Key Lime Pie opening to spikes of lemon-lime chartreuse flowers in June and July. Tinkerbelle would love to use one of these as her wand! Flowers slowly mature to a butter yellowFull sun, most soils (but prefers well drained), drought tolerant and deer resistant. Easy!
