Cosmos Sonata Carmine

Cosmos Sonata Carmine is around 40-60 cms tall and so is much smaller and tidier than the average 100 cms Cosmos bipinnatus. It provides the deep pink - Carmine is a good name - of the Sonata range. We sell three, Sonata White and Sonata Pink being the other two all of which are dwarf Cosmos that are ideal for smaller gardens, window boxes and container gardening in general. It is certainly the best dark pink Cosmos for your patio, terrace, balcony or roof-garden and it is because of this as well as its incessant production of stunning carmine flowers that we chose this to be part of our range of ready to plant cosmos seedlings.

We think cosmos look much better planted in numbers rather than in one's and two's. As a drift of maybe a dozen plants, in a single colour or mixed if you prefer, Cosmos Sonata Carmine is a sight for sore eyes.

Belying their size, Sonata Cosmos produce quite remarkable numbers of flowers almost without catching breath from May until November. These are smaller plants than most other Cosmos - such as the Double Clicks - so the flower stems will be shorter than those produced by taller varieties but, although we have not tested this scientifically, they seem to produce about as many flowers.

Plant Cosmos Sonata Carmine seedlings in well prepared, moist soil that ideally was enriched with a little organic matter the previous autumn. Not too much as Cosmos flower better if the soil is not overly rich. Water well after planting and for at least a week after that just to make sure they establish well.

The Sonata series of Cosmos are ideal for growing in containers as none of them reach more than 50 cms tall. However they are bushy plants, and so need enough compost in the pot to stop a strong wind blowing them over so we would suggest using pot sizes of at least 5 Litres and preferably a bit more. Any general purpose compost will do here.

The main requirements are that your plants have enough light and water - they grow very fast and flower hugely through summer so moisture is important. They can cope with a little shade but flower better in full sun. As a guide, they need a bare minimum of 4 hours direct light a day, but they do better with more.

Because you are buying seedlings, you can plant your cosmos into their final flowering positions immediately. Space your plants 20-25 cms apart and (in a bed) plant them in drifts of 12-15 plants. They will either need a 60 cms cane per plant (which should be pushed in about 25 cms deep and about 5 cm from a plant) or a support made of twine or pea/bean netting. This should be stretched between canes about 20-30 cms above ground level and the cosmos can then grow through it. It is not pretty at first but the plants disguise it very quickly and it is an effective solution. Just don't plant a group that is so big you can't reach the middle...

As flowers develop cut them or dead head when they are over and your cosmos will carry on flowering all summer long. Well grown Cosmos can quite literally produce a hundred flowers or so per plant in a season.

To maintain flower quality and size, you can use a high potash and phosphate fertiliser every fortnight throughout summer. Home-made comfrey tea is perfect or one of the specialised tomato fertilisers will do very well.

Delivery: The basic delivery charge for orders of bareroot plants is £6.50 + vat, which increases to £12.55 + vat if you add any pot-grown plants, standard trees or fruit trees to the order.
Because couriers sometimes experience delays, we schedule delivery by week, not by day. Therefore, please plan your planting day for the weekend at the end of the delivery week or for the week following delivery, at the earliest.
We will email you the day before your plants are due to arrive.

*Surcharges to the Highlands and Islands still apply.

Payment: We do not charge your card until we begin to prepare your order for packing.

Guarantee: If any plants die within a year, we will replace them. We only ask that you follow our planting & growing instructions and sent us clear photographs of the dead plants in situ, so we can help to make sure that the replacement plants succeed. You only pay for the delivery of the replacements.

Please note that our guarantee is void if there is a hosepipe ban in your area: your newly planted hedging must be watered in dry weather while it is establishing. The best way to water is very thoroughly every few days: at least once a week if there is no heavy rain.

Our nursery has been supplying container grown and bareroot hedging plants to gardeners, farmers and town planners since 1949. Our website started in 2003, so we do understand the concerns that you may have about buying hedging plants online.

We will give you a refund or send replacements and send a courier to come and collect the unwanted plants.
