Wonderful Garden Citizen

Unlike the reviews I have found for other milkweeds, i.e. they spread aggressively, this milkweed is a good garden citizen, staying in a clump where planted. Growing to about 24" in my mid-Atlantic PA garden, the bright, exotic and cheerful flower clusters remain for about two to three weeks and then form the amazing pods that are absolutely packed with flat, brown seeds with fluffy tails that carry them into the wind. There are hundreds of seeds from each clump, but none have spread in my garden. Every year I look forward to this beauty. All pollinators seem to like it. I have found that if I deadhead the first blooms, the plant reliably produces a smaller but welcome second bloom. Full sun or they lean. A true favorite of mine. This coming season, I will make an effort to propagate the seeds under lights or outside in trays.

Help rebuild the Monarch butterfly's habitat with these showy plants. As the host of choice for this delicate insect, Asclepias foliage is the singular food source to the Monarch larvae. The blooms are a rich source of pollen and nectar for the adult butterflies and also attract hummingbirds, bees and other beneficial insects. Typically durable plants, they are adaptable, drought tolerant and deer resistant.

The color and beauty of a flower garden can lift the spirit and renew the soul, and a bouquet of fresh cut flowers will bring sunshine into your home. Over the years we have conducted extensive flower trials, concentrating on varieties that are easy to grow-many from direct-sowing- have superior color and fragrance, and make a good cut flower. Take a bit of time, relax and enjoy a cup of steaming hot chocolate, and look over our selections. We think you'll find just what you're looking for.

Germination Codes
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

Direct Sowing
• 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
• Early watering and good weed control will generally alleviate most problems
• Pyrethrin will control most insects

Harvest & Storage
• For fresh-cut flowers: Harvest in the morning when flowers are their freshest and petals are just opening
• Cut with a clean knife that has been dipped in a solution of 10% household bleach
• A few drops of bleach in the vase will prolong their beauty
