Single Packet of 100 Seeds
Grow a garden filled with Hello Yellow Milkweed, from freshly harvested Asclepias tuberosa flower seeds. Hello yellow is a cheery variety of Milkweed that produces clusters of bright yellow flowers through the Summer months! The plants grow to a mature height of about 24 to 30 inches tall, attracting a large majority of beneficial insects to the garden.
Hello Yellow, like many other varieties of Milkweed is considered to be a perennial flowering plant. Perennials will establish a deep root system within the first year of growth. The plants will later wilt during the first frost, but should return the following year once the temperatures warm up. The blooms might not appear for a year or two, but trust us, the wait is well worth it, because these beauties are a showstopper.
Monarch butterflies occupied much of North America in the many years prior to 2015. Recently, studies have shown that their numbers have dwindled by nearly 96% over the decades, leaving them hanging on the edge of endangerment. This migratory species is exposed to numerous threats along its pilgrimage, but the number one threat it faces is the decrease in Milkweed plants available.

Sowing The Seed
Asclepias flower seeds will need to go through a process of stratification for successful germination. Place your seed packet in the fridge for roughly 3 to 6 weeks prior to sowing.
Asclepias seeds are best sown indoors, where the environmental conditions can be maintained for optimal growth. Sow in peat pots, 6 to 8 weeks prior to the last killing frost, at a shallow depth of 1/16” under topsoil. The seeds will require light to germinate, so it is crucial that you do not cover the seeds with much dirt. Transplant or direct sow outdoors when the weather is warm and all danger of frost has passed.
Asclepias will enjoy an area of full sunlight for the majority of the day with temperatures of at least 70F to 85F. The soil should be rich in organic matter and also well drained. It is recommended that you combine any hard compact soil with a light fluffy compost to increase drainage. Water daily so that the seeds are kept moist until germination has occurred.
Germination & Growth
Milkweed seeds will show signs of life within 14 to 28 days, but can take up to 40 days to successfully germinate. The plants will grow to a mature height of roughly 24 to 30 inches tall and can be spaced roughly 12 to 18 inches apart from one another. Milkweed is a crucial food source for the Monarch Butterfly. It will also attract an array of other beneficial insects as well.
