This is my first year buying form Sarah Raven. It was an idea that my daughter purchase plants for my birthday back in April. The plants have been stunning, my garden has NEVER looked so good and friends have commented on the show. One plant did not thrive and you gladly replaced, amazing service. I have and still am a very proud gardener this year thanks to just looking at your brochure and being inspired. Many, many thanks
I would take pics but today we are in the middle of torrential rain

Oh how I love this plant, bought it last year and it lasted for months. It is such an outstanding plant, really sturdy and I plant it around other plants in a large tub. It can get quite tall and gives a lot of structure to any display, will continue to grow this plant. Service and packaging as ever very good.

Three very healthy plants arrived and have been flowering a couple of months now. I have only knocked a star off because they are very short stemmed so not really good for flower arrangements but I do like them on their own in a posy. Worth the money for something a bit different and they really do last ages in a vase!

The plant was almost dead when it arrived and the soil was mouldy. After complaining the plant was replaced but it took weeks for the replacement to arrive.
I appreciate transporting plants must be difficult but it obviously needs to be right.

Definitely unusual, but I found this plant to be a bit too small to have much impact in my flower arrangements. I can imagine it would work well in small posies, but I like my arrangements to be big and boisterous. It didn't grow very tall for me, only about 12 inches, not the 18 inches it says on the website, but that may have been the hot summer and drought (2018). Also the heads were not 'spidery' like in the pictures, but rounder, like a half ball. They do last a long time in the vase though.

Loved these pom-poms. They stay a vibrant green and last for ages. They did better in a pot than window box as they are tall stemmed and lean out after a while. Look great with the Erigeron daisies or other perennials.

Well worth the money

I had fancied these for a long time but resisted as they seemed rather expensive. I'm glad I splashed out though as they are truly lovely. Surprisingly tall plants, rather floppy, bearing multiple flower heads which despite their fluffy appearance are actually quite robust. They last very well in a vase. If mine don't come back next year I shall certainly buy some more.

Unusual cute Green plant

I purchased these last season and they did really well, I even cut a few for a floral arrangement I did at class and they added a different texture. The flowers lasted ages in the garden. I thought they were just an annual but to my delight they have appeared again this year, there aren't as many flowers but still two out of the three plants have come back again. I will be buying more plants next season so I can cut more of these very cute little green flowers. I love them. Yes I would recommend them to anyone who likes something a little bit different.

I have never seen flowers like these they really are Tdf!!!!
We have a holiday let on Anglesey and the number of guests that have commented on them is amazing.
We live over the road from the sea and I was a bit worried about the salt wind but I needn't have bothered. It's now November and they are still flowering like mad.
Can't tell you enough how much I recommend them.
