Cosmidium burridgeanum If you like Chocolate cosmos, you'll love Phillipine! With slews of cocoa scented, bicolor flowers, it's sure to be an immediate favorite. Henna colored petals, rimmed in golden orange, surround a burgundy eye making the blooms extra showy. The 16 inch plants are well branched and extremely uniform for perfect borders and sensational containers. Received quite a bit of attention from visitors at our flower trials.

Given at the end of each description to give you specific information.
(1) Germination occurs between 70-85°F and within 6-15 days. Sow indoors and cover lightly.
(2) Needs a period of pre-chilling. Mix seeds with moistened peat moss and place in plastic bag. Seal and place bag in an area where the temperature is around 60°F for 2-3 days. Then place in the refrigerator for 30-90 days. After pre-chilling, place seed on sterile seedling mix and cover lightly. Germination may take up to 30 days.
(3) Needs darkness to germinate. Remove cover as soon as germination occurs.
(4) Direct sow in the garden as soon as the soil warms to at least 55°F.
(5) Germination may be slow and erratic. A fluctuating temperature of 75°F during the day and 50°F at night may help.
(6) Needs at least 12 hours of light per day to germinate. Press into the medium but do not cover. Keep moist.
Note: For those varieties that indicate a (1) or (6), a very light covering of vermiculite will allow adequate light to the seed and keep it uniformly moist.
• As a general rule, flowers can be sown when soil has warmed to at least 55°F
• Apply 1-2 cups of TSC's Complete fertilizer per 5 row feet, and 1 inch of compost
• If you prefer to soak your seeds: soak in 85°F water for 1-3 hours and plant immediately — longer soaking times are often detrimental; seeds need air to live
• Seeds should be buried 2 times their narrowest dimension and covered with finely raked soil or vermiculite unless otherwise noted
• Some varieties can take over a month to germinate so mark your rows, keep them moist, and for larger seeds like sunflowers, use bird netting
• Sow 5-6 weeks prior to anticipated transplant date
• If seeds need darkness, cover with 2 sheets of newspaper or plastic, remove upon the first signs of germination
• We recommend feeding your seedlings Age Old Grow, diluted to 1/4 strength
Insects & Disease

|Soil Temp for Germ.||Days to Emergence||Seed Depth||Seed Spacing||Row Spacing||Thin Plants To|

• Germination code: (4)
Insects & Diseases
• Common insects: Cutworms and weevils
• Insect control: Azatrol or Pyrethrin
• Common pests: Birds
• Pest control: Bird Netting or flash tape
• Note: Avoid wetting foliage to prevent rust
Harvest & Storage
• Cut flowers in the morning just after they open
• Use a clean knife, a clean vase, and a few drops of chlorine bleach in the water
• Cutting the mature central flower head will promote side-shoot flower production
• Harvest the heads when the bracts begin to shrivel, and hang the flowers upside down in a barn or shed
• For seed-eating gardeners, gray and white striped sunflower seeds are the best choice
• Salting: When dry, rub the seeds off the heads and soak overnight in 1 gallon of water with 1 cup of salt added, drain, and then dry in a 250°F oven for 4-5 hours and store in an airtight container
