I was pleased with them but the dry and very hot summer meant that they did not all flourish. This was my second attempt to find salvias which fit well with my Absolutely Fabulous roses. The amistad ones were too big but a better colour. These were a better size but rather pale against the yellow roses.

One of these seedlings has mildew on when it arrived and hence didn’t survive. Others were all in good condition.

These were reasonable but I found my own, grown from seed, were more robust and looked stronger and healthier. These were a bit leggy.

I sewed these for the first time last year. They were strong lovely plants and flowered right through into late autumn.
They looked wonderful under the Nicotiana alata 'Lime Green' and frankly wherever else I put the excess plants.
Am about to reorder more seeds for this season.

Very good 'space filler'

Seedlings started off slowly but really got going once I planted them out. They've been flowering ever since. Will definitely sow again next year.

I grew these from seedlings received in March this year and they still look good now, in November!! So easy to grow and requiring little attention & look gorgeous in the vase & in the garden, with a bit of back lit sunshine.

These are excellent flowers. Very easy to grow from seed. They look very good in the border and around the edge of pots. Excellent, long lasting, cut flower.

Reviewed 8th June 2016 by Katy Ling

I grew this plant for the first time last year in a newly landscaped garden and found that it gave me everything I was looking for - easy to germinate, fairly quick-growing, highly sought-after by bees, and low maintenance, requiring no dead-heading to go on well into Autumn. The blue bracts are very unusual, and, whilst it is not exactly clump-forming in itself, three or four plants together create a beautiful, spreading clump of blue and green, perfect for the edge of raised beds. It is ideal for filling gaps and lending softness against the rigidity of taller, more upright plants. All this, and hardly a nibble from our mollusc friends!

These look great in a vase with lime green annuals such as lime green nicotiana and euphorbia obligate. They are a lovely colour

I love it!

I planted the seeds in the spring and patiently waited to see what the plant would look like in its full glory. I planted them at the front of the bed with white antirrhinum and ammi majus mixing in with them, and the whole show looks gorgeous. A lovely gentle plant that I think would mix well with many other plants, and I shall definitely be growing this again.
