Dahlia 'Mary Lou'
Good yellow dahlias are hard to come by. This tall, golden-yellow beauty has upward facing blooms with long stems that make excellent cut flowers. If you’re looking for a beautiful, warm yellow variety, ‘Mary Lou’ is your girl.
Flower type: informal decorative/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.
