Description

Grow Radiance Cosmos from fresh Cosmos bipinnatus flower seeds. Radiance produces beautiful, deep rose blooms, accented by crimson coloring around the bright yellow center. These elegant flowers mature to a height of 36 to 60 inches tall. The leaves & stems of Radiance Cosmos are slender and the flowers are attractive to all sorts of beneficial insects such as butterflies, hummingbirds, bumblebees & lady bugs. Cosmos are grown as an annual flowering plant, which means the plants will grow quickly, bloom heavily and then later die with the first frost.

Cosmos flowers are best established in masses, in open fields, borders and flower beds and in random areas that need a splash of color. Most Cosmos flowers grow to a height of at least 30 inches or taller, so you may consider using them as a background / backdrop plant. Cosmos flowers in general come in a variety of different colors including pink, purple, crimson, yellow, orange, white, red and will even produce a few bi-colored blooms as well.

You may also be interested in a number of additional varieties as well such as: Gloria, Picotee, Pinkie, Seashells, Purity & more. We also offer our “Crazy Mixture” which consists of every variety of Cosmos flower we offer.

Sowing The Seed

Cosmos are best established directly outdoors. Begin by clearing your entire sowing area of all weeds and other unwanted plant life. Turn the soil, or throw down new soil in it’s place. Scatter the slivers of seed, directly to the surface of the soil, covering thinly with roughly 1/16” of topsoil. (Check "Germination and Growth" for spacing & growth habits)

Growing Conditions

Cosmos will enjoy an area that receives full sunlight for the majority of the day. Temperatures should be kept at 65F or higher, for optimal growth. Cosmos plants aren’t too picky on soil conditions, however they do require an area that is well drained. Mixing a light compost to any hard, compact soil will increase your drainage. Water daily until germination has occurred, but avoid overwatering and soaking the soil.

Germination & Growth

Cosmos flower seeds will begin to sprout within 7 to 10 days after sowing. The plants will grow to a mature height of about 36 to 60 inches tall and can be spaced roughly 12 to 18 inches apart from one another. Picotee produces beautiful white, almost pale pink flowers that are accented with rose edges. Attracts an array of beneficial insects such as butterflies, hummingbirds, ladybugs and bumblebees.

Love the dark centers on these cosmos!

These grew really well and seemed to like the warmer temperatures. I'm near Phoenix, and the blooms really took off once the temps were over 90, and lasted a couple of weeks into the 110s, in full sun.
