High winds meant lots of stakes! I didn’t realise that the Cosmos were the tall ones. Otherwise great.

They never fail to impress. Your phone service is very helpful. I plant these 2 plants together in very large white pots and yet again am asked where from. They have never seen Cosmos so healthy and large and Ammi the same. (The latter being my favourite flower.). Friends always say that from home grown seeds the flowers never look anything like mine. What is your secret?!

Almost without exception, the purchases arrive in good condition and the new packaging has made a noticeable difference to this aspect.
Queries are answered promptly and I find the information in the brochure, the website and when speaking directly to staff-members clear and helpful.

Terrible. I have had these for 3 years now, and only once have they performed well. Last year the heat damaged them. This year just very, very poor. Especially the Ammi, of which 60% are already pretty much dead, 20% flourishing and 20% below average. AND they all in the same plot.

Reviewed 7th September 2018 by Caralyn

The quality of the seedlings was very high and most of them have done well even in the extreme heat and extraordinarily dry weather, although the larkspur less well. The nicotiana and cosmos have made huge plants and are still full of flowers. The achillea and thalictrum have been slow but have now made good small but sturdy plants that I hope will do well next year.

I bought these in March and sowed them, for the past few weeks I have had a stunning abundance of beautiful white flowers that have a delicate scent, they seem to be getting better and better - with multiple flowers from each main stem

I would highly recommend this variety
