Poppy

There are many varieties of poppy. Some like the breadseed varieties have culinary uses and are the opium poppy. Others like Papaver rhoeas, are associated with WWI due to battlefields blooming with poppies. The seeds can remain dormant for long periods of time. As the seeds need light to germinate when battles disturbed the soil, Papaver rhoeas would bloom.1

Growing Tips

When to Start

 

Transplant: Not recommended.

Direct Sow:  After the danger of frost has passed. (May 1 for Jefferson, GA)

Fall: Direct sow in late fall. (October is my best guess for Jefferson, GA)

 

How to Start

 

Some gardeners recommend cold stratifying the seeds for 2 weeks to break dormancy before planting. Many authoritative websites, like Burpee, don’t mention this as being necessary. So, you may not need to go through this process. However, if you have problems with the poppy germinating, this could be the reason. 

Direct Sow in late Fall.

 

Care

 

Poppy is typically easy to grow.  However, Georgia’s humidity and improper watering techniques can make growing poppy challenging. Sow poppies evenly and thinly into poor to average soil in a full sun bed. Gently press into the soil or barley cover to keep it from blowing away as poppy seeds need light to germinate. Keep evenly moist. Thin to 12 inches when 2 inches high. Mulch.

 

Poppies grow a taproot. When this taproot is disturbed in transplanting, a lost season of bloom may occur. That being said, transplanting is possible, just transplant when they are very young before they get too mature to avoid disturbing the taproot. This can be tricky which is why it’s not recommended. Dead-head plant to encourage more blossoms, until you are ready for it to go to seed.

 

Poppy flowers need limited watering once they have settled into their location. Too much water can result in tall, leggy, unattractive growth of the growing poppy flower. Water to a depth of 1 inch weekly. Water in the morning and use soaker hoses to keep the plants healthy. See Tips and Tricks for more info.

 

To overwinter perennial varieties, add 1-2 inches of mulch in the fall. Cut back foliage after it has died back.  If the poppies need dividing, do so in autumn to allow time for the taproot to restore itself.

My personal experience

Poppy’s are my favorite flower. They are just so beautiful and delicate! But they sure are a challenge to grow in GA. I’ve tried every year for several years now to grow poppies with varying success. Poppy in GA needs proper spacing as it will get a fungus otherwise.

 

I have the most luck with volunteer plants verses transplanting. I know you’re not supposed to transplant, but I do it anyway. It usually works at home.  Haven’t gotten it to work in the Library garden yet. You just transplant when they are very young and do your best not to disturb the roots.

 

My next experiment is to try sowing in the fall. I’m hoping this will proove to be a success. By letting the seeds over winter, this should give the seeds the cold-stratifcation they seem to like and it avoids the whole root disturbance issues. We’ll see how this goes!

My first time

My first time planting poppy I grew Shirley Temple mixed colors. I just loved that I could get 3 different colors of flowers on one plant! They ranged from this bright red to a light pink to a mix of the two. Gorgeous! Isn’t it!

Seed Saving

Isolation Distance

 

Insect dependent for pollination. Isolate 300 feet to prevent cross-pollination.

 

Instructions

 

Select healthy, robust plants free of any signs of disease or insect infestation for seeds. Seeds carry the traits of the parent plant. Choose plants that exhibit the traits you wish to preserve. Consider bloom size, color, and shape, as well as blooming time.

 

Allow the biggest and healthiest blooms to mature on the plant. Cover the seed head with a fine-mesh bag as soon as the flower petals shrivel and die. Use an elastic band to hold the bag in place. This prevents seeds from spilling onto the soil before harvest.

 

Clip the flower head from the main stem once the seeds are dry and dark. Separate plant debris from the seeds by removing the mesh bag and placing the flower head in a paper bag and shaking to loosen the seeds. Seeds settle to the bottom of the bag. Remove plant debris by hand.

Features

  • Container friendly for the Ladybird variety
  • Dry area tolerant
  • Generally easy to grow and maintain
  • Amazing Grey: Heirloom. Booms are a shirley type with papery great, lavender petals. 
  • Brilliant Red: Huge, bright scarlet-orange flowers feature black blotches at the base of each petal. Plants bloom profusely in May and June. 
  • Ladybird: Heirloom. Blooms are lipstick red with black spots. Perfect for bedding and borders. 

Poppy is susceptible to various fungal problems. Botrytis (gray mold); downy mildew; powdery mildew, as well as root rot. 

To help prevent these problems, avoid overhead watering. Provide adequate drainage and avoid overwatering. Use soaker hoses for bottom watering and space/thin plants to allow for good air circulation. Remove any plants that get Botrytis to prevent spread to other plants. And rotating plants will help prevent the spread of disease. 

For any pest problems see Pest Management for ideas.
