HOW TO GROW

Sowing: Direct sow in late fall, planting on the surface of the soil since these great blue lobelia seeds need light to germinate. For spring planting, mix the Lobelia Siphilitica seed with moist sand and store it in the refrigerator for 60 days before planting. To start indoors, sow the seed 6-8 weeks before the last frost of spring and keep the soil lightly moist until germination. Transplant the seedlings as soon as they can safely be handled and there is no chance of frost.

Growing: Keep seedlings well watered and control weeds. These plants need continual moisture, and thrive even in very wet soil. To encourage bushier growth, pinch back the stems before they bloom. These plants may self-sow in good growing conditions. Mature plants can be divided in early spring. These flowers attract hummingbirds and butterflies, and flourish near ponds or streams.

Harvesting: These blooms make excellent cut flowers. Choose stalks with flowers that have just opened and place them in water immediately; strip the foliage that will fall below the surface of the water.

Seed Saving: As soon as the flowers fade, watch the seed heads carefully since the tiny seed can easily blow away in the wind. Shake the Lobelia Siphilitica seed heads over a container to remove the ripe seed; repeat until all the seed has ripened. Store the cleaned great blue lobelia seeds in a cool, dry place.

Great Packaging

I just received my order from Everwilde Farms. Although, it is still early to start planting my seeds at this time, I couldn't be anymore impressed with the packaging the seeds came in and the concise planting instructions on said package. I can't wait to get these seeds in the ground in about a month or so.

5 stars for now. Let's see how they grow!

Arrived promptly and packaged as promised. Will update with pix mid-summer as to "how they grow". I've purchased other seeds from Everwilde in the past and had excellent results.

Nothing grew

I tried starting inside and out, nothing germinated.

Hello, these cannot be direct planted in the summer. They first need to go through the winter cycle to sprout. If you start them indoors, they need to be stratified. Please contact customer support any we will ship you a new packet so you can try again or we can refund if you prefer.

Great selection filters for native plants

I have been trying to grow native plants for the environmental benefits and to support insect and bird populations. You're website made it so easy to identify native flowers for my region. The growing tips are also much appreciated.

Overwhelmingly great!

Started seedlings indoors in early spring, put out in garden after last frost date, they are all growing lustily, and beginning in early August I have gorgeous full spikes of bloom that last forever in the vase. Once you cut the central stalk you get amazing side shoot flowering that really turns each plant into a lovely bush of flowers.

Great packaging - one suggestion

One of the packets contained spores that were so tiny, they were tough to sow. Suggest adding carrier material.

Planted this puppy 2 years ago. Last year was a modest showing, this year is "WOW, did I plant that?". Will be planting this variety elsewhere in the garden!.

DESCRIPTION

These intense blue beauties contrast beautifully with Cardinal Flower - their deep red cousin. Both love moisture and can be planted in low-lying areas such as around ponds or near streams. The tall spikes are also attractive to hummingbirds and butterflies.
This plant's genus name of Lobelia honors Flemish botanist Mathias de Lobel, who studied medicinal uses for plants. "Siphilitica," the species name, is derived from a folk belief that this plant could treat syphilis.
