The Little Rocket
Zone 3 - 9
Just like 'The Rocket' but half the size.   Forms a nice clump of deeply toothed, heart-shaped foliage.  In early-to-mid summer it develops purple-black stems bearing long racemes of bright yellow flowers.   Wonderful in a mass planting.  Easy to grow in a partially shaded location and moist, fertile soil.  Keep it out of the hot afternoon sun.  HEIGHT: 70-100 cm   SPREAD: 60-75 cm
1 gallon size
