We purchase 3 Dark Knight Blue Mist Spirea in early May 2016. When they arrived, as others have noted, they were about 2-3" tall, at most. This was surprising, however, I called High County Gardens and they explained that they intentionally prune the shrubs down to a small size from the ground up so that they are not damaged in shipping, although the root ball is more substantial so that by the end of growing season they should be anywhere from 75% to full grown. I have to admit, I was a bit skeptical, but my skepticism could not have been more off. I would guess they are about 60-70% toward full growth at this point. They are beautiful plants, and I only expect them to fill out into next Spring (2017) growing season considering their growth in their initial year.The original plantings, as mailed, can be seen in the first photo in between the Mexican Feather grasses. As you will see, the Speria got so large, we eventually transplanted the Mexican Feather grass and left the three Speria shrubs by themselves.We loved them so much we recently bought 4 more plants to continue lining our fence. Great product.

Plants small and not robust
I ordered six of these. When they arrived they were all very small. We were doing planting of a new yard and we planted about 300+ plants from roses to trees to bulbs...Read complete review
I ordered six of these. When they arrived they were all very small. We were doing planting of a new yard and we planted about 300+ plants from roses to trees to bulbs from other online and local nurseries. Of the six I ordered, only two survived...and just barely. All the other plants that were put in are doing well and waking up in the spring. Our order was shipped in the fall so perhaps we got left overs, Based on the survival rate and the costs I would not recommend this. You may have better luck if you order earlier.

Comments about High Country Gardens Caryopteris clandonensis Dark Knight:
Had this plant years ago but I trimmed it back in the fall and it died over winter. Won't make that mistake again. Great late season color. The plant put on impressive growth despite my ordering mid summer.
Bottom Line Yes, I would recommend this to a friend

Beautiful Shrubs and so unusual
By Kathy H
from Blairstown NJ
Put these 2 shrubs by my hydrangea to give some life after the hydrangeas died back for winter. They are gorgeous now with their blooms and give some life to,the area where the hydrangeas fade back.

Beautiful flowers, tough plant!
By Crickets Meyeres
from Kanab UT high desert
Even more sun and drought tolerant than expected! And the lavender blue flowers are even prettier than I thought they would be. I planted when it arrived in May and it is already blooming and has grown a bit as well. I can hardly wait until it is back in stock so I can buy more

First year had fabulous growth!
By Cathy B.
from Brush, CO
Competitive and thriving in semi-shade (gets 3-5 hours of sunlight), even when in competition with ground cover and overhanging cherry branches.
Finally some decent sized starter shrubs from HCG
from Fort Collins, CO
In a year of disappointing plants from HCG this was one that I fell good about. Many of these HCG starter shrubs have been quite small, but my two plants were tall and seemed quite vigorous. They haven't filled out much in their first season, but did put out some flowers even on their lanky stems. In a few years I expect them to look quite nice.

Turned into a giant.
from Orofino, Idaho
this plant has always been satisfactory, but this year, a wet year in North central Idaho, it has grown to sprawl all over the roses next to it and over the lawn. I haven't fertilized it. Can anyone help?

Great drought tolerant plant
By Green thumb gardener
from Walsenburg, Co.
In response to some of the other reviews: HCG plants may be a little small when they arrive, but given just a little compost and water until they're established, they will double even triple in size. We planted a large flower garden in southern Colorado using HCG plants (and some others from other sources) and were amazed at how much the HCG plants grew in just the first year. Blue Mist Spirea Dark Knight was one of those plants. We had 3-4 foot wide shrubs by the end of the second summer. All we added to the dirt was some compost. It's a beautiful plant.
Caryopteris does well for me in the garden
By Long time gardener
from Santa Fe, NM
I had several of the blue mist plants when gardening in the Pacific Northwest. Most plants grow so well there that I took this plant for granted. Now I am gardening in Northern New Mexico, and most plants do not survive well. What does fairly well usually gets eaten by the rabbits, even rabbit resistant plants. I am impressed with how well these plants do--they help carry the garden through the heat of the summer and well into autumn. I will always have this plant in my yard.

Not what was expected
By Bummed out Bob
from Avon, Indiana
Arrived - 1 dead, and one grew for 2 weeks and then died. But I was most dismayed when they arrived and they were the tiniest shrubs known to man. I don't know if they will grow to their full maturity before I die (I'm guessing 20 years)
Merchant response: Good Day Bummed our Bob,We are so sorry to hear that the Caryopteris Dark Knight did not survive! We are not sure what the cause might have been but please know that we are truly committed to your success.

from Houston Tx
Just purchased 3 of these plants. NO WAY I would have ever spent the money on them if I realized the plants would be 2" tall. I am so very disappointed.
from OFallon, Missouri
Performed very well for it's first year. Needed no maintenance at all.
