10 Seeds Monarch Butterfly Plant Seeds - Great Butterfly Plant!!! Milkweed plants --"Butterfly Plants" are the host plants for Monarch butterflies...but milkweed is also a highly sought nectar source for many other butterfly species! Aside from attracting Monarch butterflies for egg-laying, milkweed entices swallowtails, painted ladies, American ladies, red admirals, fritillaries, and hairstreaks for nectaring. Milkweed also draws hummingbirds and hummingbird clearwing moths to the garden for nectar. Germinating, Growing and Transplanting Milkweed seedlings can be started indoors in a greenhouse or under artificial lighting and then transplanted outdoors after the average date of last frost. If seeds are started indoors, allow 4-8 weeks growing time before transplanting. Plastic flats can be used to start the seeds. Fill the flats with a soil mix suitable for seedlings (most potting mixes are), thoroughly soak the soil, and let the excess water drain. Sow the seeds by scattering them on the soil surface 1/4-1/2 inch apart, and then cover with about 1/4 inch of additional soil mix. Gently mist the soil surface with water to dampen the additional soil mix that has been added. In an effort to improve germination rates, many gardeners place the seeds in packets made from paper towels and soak them in warm water for 24 hours prior to planting. This method seems to work especially well for seeds of species that require vernalization . Our seeds/bulbs are guaranteed to be fresh but are NOT guaranteed as to results. Sorry, but there are too many variables in gardening that can impact germination. Flower seeds/bulbs are a live organism. Their germination depends on many factor including heat, cooling, sun, shade, moisture, time of sowing, etc. None of these things We can control so We can not be held responsible for them. So please do not ask for a refund, replacement or to return unused seeds/bulbs.
