'Golden Jubilee' shares most features of the straight species Agastache foeniculum but has brilliant chartreuse leaves.  It is particularly attractive to native bees and will bloom July through autumn with anise-scented lavender blooms.  Goldfinches will dine on seed heads if left in place.  
 
Will self-seed.  Surface sow in fall or start indoors 6-8 weeks before last frost after cold stratifying to improve germination.
