Gomphrenas, on the contrary, love warmth. The Gomphrena’s colors are diverse. You may come across pink, crimson, white, or red Gomphrenas. In curb planting, Gomphrenas mix well with buttercups. Blue or purple Lobelias look great with pink or white Gomphrenas. PinkLobelias serve as a perfect background for red Gomphrenas. Gomphrenas are heat-loving annual flowers with a bush height of up to 20 inches (50сm). The flowers have a cone shape. The hybrid of gomphrena is Strawberry Fields which grow to about 25 inches (60сm) with large dark-red flowers that grow out to 2 inches (5сm).
How to plant annual flowers
To create a beautiful composition from annual flowers, choose a well-lit location. First, you need to prepare the soil. Annual flowers prefer well-fertilized, drained neutral soil.
Gomphrenas are planted in the spring to obtain seedlings. Before planting, the seeds are soaked for 1-2 days for better sprouting. In 2-2.5 weeks the seeds should sprout. The seedlings may be planted out in the open soil when there is no possibility of light frosts.. Taking into account the fact that a bush of gomphrena will grow thick, you should add the seedlings of Lobelia at the distance of 12 inches (30сm). Gomphrena and Lobelia bloom for long periods of time. To get fluffy bushes of gomphrena, young twigs are grafted.
Care for annual flowers involves soil tillage, the removal of weeds, and regular watering.
Lobelia also loves fertile light soil. The bush’s height doesn’t exceed 6 8 inches (15 -20сm).
Annual Lobelias have small seeds. It’s not easy to maintain moisture in the open soil all of the time. In addition, any gardener wants to decorate his or her garden with blooming flowers as soon as possible, which is why the Lobelia seeds are often planted in pots or containers at the end of winter. The soil is carefully moistened, but not flooded. The pot is covered with glass or transparent film. Many annual flowers with tiny seeds are planted the same way as Lobelias.
The sprouts of annual flowers appear in 2-3 weeks, with a temperature of 68 - 75.2F (20-24ºС). When the seedlings grow to 1 inch (3сm), they may be planted out into the lawn’s soil, on the condition that there are no more light frosts. Usually, the seedlings need to be conditioned to the cold before being planted out into the open soil. That’s why it’s good to create cooler conditions periodically and expose the little bushes, which have sprouted, to the open sun. This will improve their acclimation rate when you plant Lobelia out into the lawn’s soil.
The distance between the plants may be 8-10 cm, depending on what kind of a flower-bed you want to arrange. If you want to plant a mix of annual flowers, it’s better to plant Gomphrena as a background for land-covering Lobelias.
Lobelia blooms well in the sun. It tolerates a semi-shadow but doesn’t blossom so well. It’s poorly subjected to diseases. It may be used as a soil-covering plant, which blooms abundantly to decorate the curb. Blue Lobelia blooms all summer long. These annual flowers are great for hanging baskets and flowerbeds since the flowers create a continuous carpet of blue, purple, white, and pink flowers.
You may plant species of blue Lobelia erinus Blue Wings, Lucia Dark Blue. Besides blue Lobelia, there are types of purple Lobelias, such as erinus Crystal Palace.
Gomphrena species Gomphrena globosa, Bicolor Rose, Strawberry Fields, Gnome Pink can be planted in containers on the balcony.
Care for the Lobelias includes timely watering. If you want to maintain them for decoration, you need to remove flowers which have already finished blossoming. These annual flowers are rarelyaffected by disease or pest infestation.
Once a month, you can fertilize annual flowers with a complex fertilizer for blossoming plants. This will improve the aesthetic of the annual flowers. It’s not recommended that you add additional fertilizer for Gomphrena often, as it may lead to no blossoming at all.
Annual flowers blossom all summer long until light frosts begin. Gomphrena may be cut in order to make dry bouquets, which do not lose their aesthetic after they are dry. Annual flowers can decorate the curb, the entrance to the house, as well as alleys all summer long.
