Slightly disappointed

Unfortunately the cosmos have totally overshadowed the phlox and osteosphermum. I think a smaller cosmos would have been better i.e. Xanthos - although not completely white it would have blended really well with the other two plants.

Reply from the Sarah Raven Team:

"Thank you for your feedback. We are sorry to hear that the cosmos have overshadowed the other plants, what a shame. The collection normally works very well together and the variety in heights normally complement each other. We will record this feedback for future planning, if you have been feeding the plants then it might be best to hold off for a while in case it is encouraging the cosmos to grow. Pinching out the cosmos at an early stage will also ensure that the growth is more bushier and controlled."

The white pot collections is bringing me so much joy... can't recommend it highly enough :o)

Stunning and flowers for months - but keep individuals in check!

The photograph implies the relative sizes of the plants. This is not how it happened! I now assume cutting back the more vigorous osteospermum and cosmos is necessary to achieve that balance.

It is now March 2015 and the oesteospermum in this collection have flowered continuously since the collection was planted last spring! I planted up two 32cm blue-glazed terracotta pots with two 9-plant collections and the display was stunning over the whole summer and autumn, looking good until October. Every visitor to our apartment commented on how stylish they looked on the balcony! The cosmos 'Sonata White' was the main attraction with its prolific saucers staring wide-eyed at you with their yellow irises but the whole effect was necessary. I now definitely recommend staking this collection and keeping the oestospermum in check.

The phlox were the least successful - though that is being unkind - as they were bulllied out of the way by the cosmos and osteospermum, particularly suffering from not being adequately staked, flopping wildly. They lasted until October, nevertheless.

The cosmos were a huge success even after mildrew arrived in September (probably my fault: watering may have been incorrect; fed every fortnight with high-potash liquid feed and I do not spray). I eventually cut them down in late October/November.

The osteospermum have survived, unpruned, though leggy now, flowering continuously through the winter, though the flowers often failed to open completely in the cold. They are too leggy to keep unless I had the space to cut them back and replant elsewhere, as I'm going to try the pelargonium and convolvulus collection this year - and need to find somewhere to put more cosmos 'Sonata' as after this display, I cannot do without it!

Reply from the Sarah Raven Team:

"Thank you very much for your review, and yes, the cosmos and osteospermum will flower for a very long time with regular deadheading."

almost total failure

Planted quickly, but cosmos seedlings died after few days. More were sent gratis - these too died (my cosmos grown from seed are always great!). Phlox was very feeble. Only osteospermum fairly OK - some action in Oct/Nov. Am not inexperience gardener, but will NEVER buy seedlings again.

Reply from the Sarah Raven Team:

"Thank you for your comments. We're so sorry to hear of your disappointment with the seedlings. We normally have great success from all our seedling ranges, and lots of lovely photos of these pot collections on our Facebook page.

Please get in contact with our Customer Service team who can supply further information, if you would like."

If it were possible to award 10 Stars, I would! . It is now mid Sept. And the show of flowers is quite exceptional, as it has since mid. June. I would most strongly recommend this lovely collection.
