Gardeners' Notes:

Positive wisedragonfly On Jul 4, 2013, wisedragonfly from Matamoras, PA wrote:

I purchased this plant at a garden/farm in Warwick, NY. The beautiful blue flowers caught my eye and I had to have it! I was told it was a tender perennial and it would come back if it was in a protected spot. I live in Matamoras, PA (about a 1/2 hour from Warwick) and I planted this in my butterfly/hummingbird garden. The garden is against the back stone wall of my house and faces southeast. The area is well protected from winter winds - I have some canna and lupines that surprised me when they came back this year! It receives sun all morning, almost up to 1:00pm or so. With all the rain and humidity we've been having recently it is doing very well. I have it planted with red bee balm monarda, pink and white cleome, cocosmia montbretia "Lucifer", blue balloon flower, and an Echinacea "Sombrero Coral Hot" coneflower" . As you can see I love color! This delphinium seems very happy and is doing very well!

I also just found mine at Lowe's a few days ago, and have never seen such a beautiful royal blue color. I am anxious to see how well it does, since we're having a lot of rain. I'm very happy that it's a perennial! I didn't know there were other types of Delphiniums besides the tall spiked ones. I planted a yellow snapdragon beside it so they can compliment each other. I will post a pic after it gets a little taller.

I bought 2 of these plants. They were small. Only one lived and is doing ok. Is only about 8 inches tall and has no flowers

For anyone looking for this plant, I just found it today (5/21/10) at my local Lowes (Lebanon, TN) for $3.33 each. I bought two and will put them in my garden tomorrow morning.
