I had doubts when I first opened the box. Packaged well. After planting them after two weeks they came to life and are flourishing quite well. They are very healthy and now branching out vividly. Thank you!

Giant Chicory!

I purchased a selection of blue plants. I planted the bare roots in a large planter I call the nursery. I wait until they are adapting to their new environment. When they start growing about three inches, I transplant to a larger pot, then to their permanent location in my garden. One grew to four feet. Others are 1- 2 feet! I can see buds sprouting and can’t wait until they bloom. I did have to cut the 4ft one down to 2 ft so it would get fuller.

My favorite spring flower

My absolute favorite spring flower. I’ve bought several over the years. Sometimes I’ve found they might not come up until the second year but most from this nursery come in the next spring.

I just want to say I would give 5 star satisfaction but my trees are just now in the ground. My shipment arrived fast and in great condition. The bare root trees already trimmed to perfection. I am so pleased. Been in the ground a week and already have green growth.
