Cosmos bipinnatus Lemonade
Get ready to add a touch of sunshine to your garden with our lovely Lemonade cosmos! This fabulous variety boasts delicate pale yellow petals adorned with a striking white center. It’s like a sip of lemonade on a sunny day but, for your garden!

Lemonade cosmos is the result of a combination of late-flowering Japanese cosmos varieties and their more early-blooming, branched counterparts. This unique blend has given rise to these soft-toned blossoms that just keep coming. Plus, their compact size makes them ideal for planting in patio pots and containers, bringing a burst of Lemonade charm to even the smallest of spaces. These beauties will keep on blooming throughout the entire summer. They grow to a manageable height of 60 centimeters, making them perfect for creating a charming low-border garden display. And here’s the best part: you can snip a few flowers for your vase, and the plant will keep on giving with its rapid flower production!

She is not only a beauty, but also a breeze to take care of. cosmos bipinnatus is very disease-resistant, can handle less-than-perfect soil, and thrives in both heat and humidity. Just keep in mind that they’re half-hardy plants, so when the first frost rolls in, it’s time to say goodbye for the season.

How to grow cosmos lemonade from seed?

Growing cosmos from seed is very easy. You can directly sow seeds once the soil has warmed up, but plants will flower relatively late in summer. To save space and precious seeds I highly recommend starting seeds in seed trays or pots. Begin sowing your seeds about 4 to 6 weeks before that last frost date comes around. Gently tuck your seeds into the soil, making sure they’re cozied up at around 20°C to encourage speedy sprouting.
After 1 to 2 weeks, you’ll start to see those cute little seedlings poking their heads up. But here’s a pro tip to avoid leggy plants: once those seeds have successfully sprouted, give them a slightly cooler environment. Don’t forget to provide them with plenty of light, as sometimes a windowsill just won’t cut it in providing the brightness these seedlings crave. If you are short of indoor space, sow 2 weeks later and only germinate the seeds indoors. Then, when the last frost has passed, grow them outdoors in a very sunny spot. Once the seedlings are 15cm tall or the cells or pots are full of roots, it’s time to plant out.

Planting and Pruning Tips:

When it comes to planting your cosmos, spacing is key. Make sure to give your seedlings about 40 centimeters of room to thrive.

Now, here’s a nifty trick to really make your cosmos flourish: pinching. Yes, you heard that right! Pinching or pruning your cosmos plants is like giving them a little haircut that works wonders. It’ll encourage these beauties to grow nice and bushy, ensuring a breathtaking display of vibrant flowers. So, don’t be shy – give it a try!

Deadhead the flowers regularly and don’t be afraid to cut back because the plants will reward you with a ton of new growth. Are you a big fan of cosmos, or do you like to start a small cut flower garden? Try a second sowing! Start a new batch of seeds with 4 to 6 weeks intervals.
