Description
Cosmos Daydream
Cosmos bipinnatus Daydream is well named. The rose pink of the petals at the centre of the flower fade into the palest, dreamiest pink. It really is a very pretty flower, one of the most popular in our range of ready to plant cosmos seedlings.
We love Cosmos as a plant. Given sun and water, they flower all summer long; you can grow them as a feature or just as a quick infill for a gap in the border that somehow got overlooked. The leaves are fun in May and then Cosmos Daydream begins to produce an almost endless stream of its lovely blooms in shades of pink. We think it looks best planted en masse in a border, but our next door neighbour at home uses it in containers following on behind tulips and alliums with a bid of silver variegated ivy. The effect is smashing.
Providing Cosmos Daydream is cut to be used indoors or deadheaded as the flowers fade, it will carry on delighting the eye all summer. There is probably not another plant family that flowers as hard for as long. Cutting helps that process and as cosmos is a very good cut flower - lasting 7-10 days in water we reckon that planting a patch somewhere is simply essential.

Planting Instructions
Plant your Cosmos Daydream seedlings in well-turned soil so it is easy for their roots to establish. Adding a little organic matter helps greatly with water retention, bit don't overdo it - cosmos flower better if the soil has not been improved too much. Water well after planting and for at least a week to ten days after that just to make sure they grow away well.
Cosmos also grow very well in containers but remember that they can reach 100 cms in ideal conditions 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, cosmos need a 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 25-35 cm apart and (in a bed) plant them in drifts of 12-15 plants. They will either need a 90 cms cane per plant (which should be pushed in about 30 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 30-40 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. A well-grown plant can quite literally produce a hundred flowers or so 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.
