Cosmos 'Sonata Hot Pink Mixed'
40 plus 20 FREE large plug plants
- Position: full sun to light shade
- Soil: moderately fertile, humus-rich, well-drained soil
- Rate of growth: average to fast-growing
- Flowering period: May to the first frosts
- Hardiness: tender annual
Large, daisy-like flowerheads, that come in an array of white and pink shades, appear non-stop throughout the summer and right up until the first frosts. Superb as border plants, they will also flourish in large pots - and their fine, feathery foliage is also attractive.
Grown in individual plug cells, each plant measures about 5 - 7cm tall (from the base of the root to the top of the plant). They are ideal for keen gardeners who have a greenhouse where the plants can be grown on until they are ready for planting out in the garden once all chance of frost has passed.
Please note that as we grow these for especially for you, we need to take full payment when you place your order so as to reserve stock for you. See above for despatch dates for this particular plant. To ensure that your plants arrive in the best possible condition each pack will be despatched individually.

Comments about Cosmos 'Sonata Hot Pink Mixed':
Beatiful long asting flowering period. I found them to be a bit leggy especially towards the end of the season which was October.That may have been because I didn`t plant them deep enough.

I have heavy clay soil and thinking of planting them in a sunny spot, so would the Cosmos Sonata or Cosmos atrosanguineus grow well? Would I need to remove the Cosmos atrosanguineus every year from the ground and replant them in late spring?
Thank you.Asked on 12/3/2017 by Garden Mum from Milton Keynes
Both these cosmos like similar conditions, so if you have particularly heavy clay soil that remains heavy and wet for any length of time, then they may not be ideal unless you can improve the drainage.
As for lifting the C. atrosanguineus, these are only half hardy, so unless it is grown in a very sheltered spot, it will ot survive the winter outside.Answered on 16/3/2017 by Helen from crocus
Q:If I buy the Cosmos collection - will it be clear which Plugs are which colour as I don't want to mix them - I want to isolate the white ones!!Asked on 11/4/2016 by bluebell from Chichester
I'm afraid that as this is a mixed collection, you will not be able to determine which of the plug plants will produce white flowers. If you just want white ones, then you should opt for these.

Q:Do Cosmos die down and then regrow the next year? i am looking for a low maintenance flower bed.
ThanksAsked on 18/2/2016 by Frodosa from Berkshire, Newbury
This cosmos is an annual bedding plant so will only last this year. These plug plants will give a wonderful display this year given the right conditions, but if you want plants to come back each year you need perennials.
Cosmos atrosanguineus and Cosmos atrosanguineus Chocamocha = 'Thomocha' are half hardy perennials.
Hope this helps.Answered on 19/2/2016 by Anonymous from crocus
Q:Hello, do the growing tips of Cosmos Sonata need to be pinched out in the early stage of growth to make the plants bushy? Many thanks.Asked on 2/5/2015 by Felix from Sussex
They do not need to be pinched out, but if you do it will help create bushier plants.Answered on 15/5/2015 by Helen from crocus
Q:I've got some shallow beds in full sun at the front of my house... Will the fact that these are shallow beds be a problem for cosmos? And assuming not how far apart do they need to be planted so I can work out how many I need?Asked on 25/4/2015 by FuzzyHQ from Dorset
Provided there is a good depth of soil these plants should thrive. I am not sure how wide your border is, but these plants have an eventual spread of around 30cm, so if it is narrower than that they may spill out over the path/lawn. As for planting distances, for a really strong display, I would plant them at 15cm intervals.Answered on 15/5/2015 by Helen from crocus
I don't have a greenhouse but want a border of Cosmos - can these be planted straight away on delivery once the risk of frost has gone?
Also, I would like a relatively tall variety of cosmos, how tall does this variety get and is there a taller variety available at Crocus?
Thank you in advanceAsked on 16/4/2015 by H from Beckenham
A:Ideally these should be potted up and grown on, but if you can protect them from slugs and snails, then you could plant them out after the frosts have passed. This one will grow to 60cm (we have a diagram near the top of the page) and we do have a couple of taller ones - just click on the following links to go straight to them

Q:I want to give pots of cosmos as presents. please can you tell me how many of the plugs should I put in a 2litre pot. thank you.Asked on 14/4/2014 by sandra from north wales
Eventually these plants grow to 60cm high by 30cm wide, so you could get away with just one per pot, however if you want the pot to look nice and full reasonably quickly, then I would opt for 3 or even 5 plugs in each 2-litre pot.Answered on 16/4/2014 by helen from crocus
Q:Are the Sonata Hot Pink Mixed a dwarf variety, and if so, how tall do they grow (in inches please!!)Asked on 8/3/2014 by happy gardener from Havant, Hampshire
This is a smaller form of Cosmos growing to approx 2ft tall.
Hope this helpsAnswered on 10/3/2014 by Anonymous from Crocus
Q:1) Given the current weather conditions and the fact that I only have a cold frame, would the cosmos plugs be OK in a cold frame for a while?
2) Please can you tell me the approximate height they grow to. Are they more suitable as 'back of border' plants?
Thank you.Asked on 31/3/2013 by Ice skater from Southampton
These plants will grow to around 60cm tall, and as they are tender they do need to be grown in frost-free conditions. If your coldframe is in a warm, sheltered position, then they should be fine in there until the temperatures improve.Answered on 2/4/2013 by Helen from Crocus
Q:My greenhouse is not heated. Can I grow the cosmos plugs on in an unheated greenhouse?Asked on 31/3/2013 by deeg from Leatherhead, Surrey
It really depends on how cold the temperatures are outside as these plants are tender. Very shortly, the temperatures should be starting to rise, so I suspect they should be fine in an unheated greenhouse, but they may need to be temporarily moved somewhere a little warmer if it gets really cold.Answered on 2/4/2013 by Helen from Crocus
If you do nothing else...water new plants. Make sure new additions do not suffer during dry spells. Plant up summer containers bedding once the threat of frosts has passed. Feed container plants about six weeks after planting. If it’s a nice day...trim heRead full article
After the last frost date, plant up containers with tender flowering bedding and reliable foliage plants. Line terracotta pots with polythene, taking care not to cover the planting holes, to reduce water loss through the porous sides of the pot.Read full article
