Cornflowers are the epitome of simplicity and affordability when it comes to gardening. These beauties can reach a height of up to 10 inches. What’s more, they come with striking blooms in various shades of blue, pink, white, red, lavender, and maroon.
To ensure successful growth, opt for slightly alkaline garden soil when planting. Regularly water the seeds until germination. It typically takes around seven to ten days for annuals and two to four weeks for perennials.
For an indoor option, such as in a greenhouse, sow the cornflower seeds about a month before the last frost. Or one month before transplanting them outdoors. This approach makes it equally effortless to enjoy these lovely flowers.

4. Sweet pea
Sweet peas are prized for their rapid growth. They can transform from seedlings to flowering plants in just three to four months!
For faster results, consider using starts instead of seeds. Plant sweet peas in the fall to enjoy winter blooms as they struggle in hot, humid weather. Optimal temperatures around 23°C are ideal for their growth.
As natural climbers, provide a garden arch trellis to reach their full potential. Without support, they will grow bushy and low. Sweet peas can reach heights of three to eight feet with a spread of two to three feet. This, as a result, can add a touch of beauty and elegance to your garden!

Petunias offer a burst of colour and charm with their abundant blooms. Starting from seeds, petunias take around ten weeks to grow fully. These sun-loving flowers prefer full sunlight but can tolerate some shade if necessary.
Older varieties of petunias require diligent deadheading to continue blooming. Meanwhile, newer varieties don’t need deadheading; occasional pinching or shearing helps.
