1. Flowering Maples

Although they have leaves just like a maple tree, flowering maple


are not trees.


Flowering maples are a beautiful and unique addition to any garden. They’re adorable and graceful yellow annual flowers. As their name suggests, they are characterized by their stunning leaves, which are shaped like traditional maple leaves. However, despite their name, flowering maples are not actually related to maples – they are members of the abutilon genus.

These annual flowers typically grow to be about one foot tall and make great border plants. They also look lovely in window boxes and hanging baskets, as they have a tendency to cascade over the edges. In addition to their eye-catching leaves, flowering maples also produce lovely blooms in a variety of colors, making them truly a sight to behold. Whether you’re looking for a pop of color or simply want to add something different to your garden, flowering maples are a great choice.

How To Grow

Begin by sowing seeds indoors 10 weeks before the last frost. Place the seeds in a moist paper towel and put them in a warm, sunny spot. Once they have germinated, transplant them into small pots filled with potting soil. Be sure to harden them off for about a week before planting them outdoors.

When it comes time to plant your flowering maples, choose a location that receives full sun; these annuals prefer well-drained soil and will not do well in areas that are overly wet or boggy. Once you have selected the perfect spot, dig a hole that is twice the size of the root ball and then gently place your plant into the ground. Water thoroughly to help settle the soil around the roots.

2. Calendula

Calendulas are also known for being excellent at attracting bees, so they’re not only beautiful but helpful as well. If you’re looking for an easy-to-grow flower that will brighten up your garden, look no further than calendulas!

How To Grow

There’s something special about yellow cosmos flowers. Perhaps its their graceful appearance or the way they seem to dance in the breeze. Whatever the reason, these annuals are sure to add a touch of magic to any garden. Native to Mexico, cosmos flowers grow rapidly and can reach a height of 4 to 6 feet.

The daisy-like blossoms are typically 2-3 inches across, with wide serrated petals and a yellow center that may be flecked with pink, red, or white. The delicate foliage is airy and often fern-like, giving the plant a light and an ethereal appearance. Cosmos flowers are aphid resistant and relatively easy to care for. They make an excellent choice for beginners.

How To Grow

With a little love and attention, yellow cosmos will bloom continuously from summer until fall. The best time to sow seeds is in the springtime, either outdoors or indoors, 6 weeks before the last frost. To sow the seeds outdoors, simply scatter them on the ground and lightly cover them with soil.

For indoor planting, fill a seed tray with potting mix and sow the seeds thinly. Once the seedlings have emerged, thin them out so that they’re spaced about 10 inches apart.

Cosmos flowers prefer full sun, but they’ll also do well in partial shade. They’re drought-tolerant and don’t need much fertilizer, so they’re fairly low-maintenance plants. Have fun bringing these cheerful additions to your garden!
