Dahlia Penhill Dark Monarch
Dahlia 'Penhill Dark Monarch'
Note: We are taking a break from selling dahlias in order to build up our mother stock of tubers and to improve the process for our customers and our farm crew. Learn more about our decision and the future of Floret dahlias.
We’re continuing to research and experiment with different ways to share dahlias with other flower lovers. Until we are able to offer dahlia tubers again, we have compiled a list of our favorite dahlia suppliers.
One of the most striking large flowered varieties we grow, the massive 10-12 inch smoky-plum blooms of this moody giant are loved by all who visit our garden. Plants produce an abundance of huge, ruffled flowers on long stems. If you are looking for an unusual twist for bouquets, then ‘Penhill Dark Monarch’ is just the ticket.
Flower type: dinnerplate
Site: full sun
Days to maturity: 80-100 days
Plant spacing: 12-18”
Pinch: when plants are 12” tall
Cut when blooms are ¾ of the way open, but not overly ripe. To do this, check the back of each flower head, looking for firm and lush petals versus papery or slightly dehydrated ones. Place into water with hydrator, or sear stem ends by placing into 160-180° water and allow to cool for 1 hour. Blooms will last 5-6 days.
