Foliage and flower contrast is beautiful

The dark blue flowers contrast so beautifully with the bronze foliage. It makes a very striking hanging basket.

Easy to germinate, made strong little plants for me. Currently doing well in containers and the landscape with lots of vibrant blue flowers. Would definitely purchase again.

Beautiful. Color

These seeds had great germination rate. The plants took awhile to get big enough to bloom, but now they are loaded with beautiful blue flowers. I have them planted in full sun and part shade. I will definitely plant these again.

Yes love this bold little plant

5 out of 5 stars Jul 3, 2021
Love the punchy cobalt-blue/purple little flowers with the dark metallic brown foliage/stems. It really adds a nice punch of contrast into the garden edges. The plant is very compact only 4-6 inches tall but man does it make a statement.

I started these indoors in late January and put them in my window box after danger of frost. They receive only some morning sun but bloom beautifully! I collect the seed heads and replant them the next year.

loved these seeds!

These seeds had a great germination rate for me. Seedlings also grew quickly, though seedlings that were more densely planted suffered from die off due to fungal disease later in the summer due to my humid climate. I think for those of us living in more humid areas should try to sow these seeds more thinly than indicated in the package instructions. Plants that did grow to maturity flowered beautifully and self-seeded, giving me another round of beautiful dark blue flowers that lasted until the first frost a week or to ago.

Beautiful lobelia!

The seeds were sewn indoors to get a hardy start for spring window boxes. They were prolific, and grew well all summer - cascading to great lengths. I will plant these again this year! They are lovely.

Great flower en masse in the garden once blooming, beautiful blue hue to contrast the other plants. Easy to grow and germination was great.
