Where and when to grow sunflowers?

The ideal time to sow sunflowers is in May, although it is possible to start sowing under cover in early spring.

Soil can easily be poorly fertile and slightly alkaline as long as it stays cool. However, it must be well drained, because it is a flower that fears humidity. Sunflowers also need constant sunlight throughout the day. This is essential for its development.

In the event of a windy area, it will be necessary to stake the larger sunflowers to avoid breakage, but the best is to place your plants along a wall that will protect them from the winds.

Some examples

Flowering shrubs

We will especially name the mimosa which, in the most mild climates, blooms in February with its beautiful yellow flowers. Holly should also be mentioned, because it keeps its berries red all winter and bright in some dark places. Hazelnut trees bloom their kittens at the very beginning of spring, but these are prepared in autumn and already hang during winter. Note that there are varieties with dark brown kittens, with a very nice effect.

Plants remaining green

We will first mention all the woody gymnosperms such as yew, fir or woodpecker, which remain green in winterВ holly and mistletoe are to be added to this list. One can also think of dry sunflower stems, for example, the seeds of which will attract the brines.

A few flowers brave winter to grow. For example, snowdrops and snowflakes are aptly named, as they often pierce the snow cover to establish their flowers. The Eastern Hellboron (Christmas rose) also grows in winter, and opens its flowers at Christmas time.

There are therefore enough plants adapted to the cold so that winter is no longer a sad time, but a time of celebration and joy, even in the garden!

The majority of these perennials have vigorous taproots. They have leaves divided into broad lobes or thorny segments, smooth and narrow, of a beautiful dark green, and shiny above. They form rosettes at the base and towering clumps that persist in winter in mild climates. They prefer well-drained soils and are hardy, being able to withstand temperatures down to -18 ° C.

Acanthus blooms from June to August and sometimes even later in colder regions. Some species can reach 40 cm in height and others have flower stalks over 2 meters. The flowers are clustered in dense, cylindrical, tubular spikes and often feature thorny bracts and sepals in a mix of white, pale yellow, green, pink or purple and these bracts are darker in color. These flowers, four in number, are gathered in terminal clusters.

Maintenance of Buenos Aires verbena

Once the flowers have faded, cut them off above the foliage to allow new flowering.

If you grow your Buenos Aires verbena in a pot, watch the watering: it should be moderate, but regular.

At the beginning of spring, fold back the stems at the base.

Yes Winter is not too harsh, the plant will start again. Otherwise, the seedlings will take over.
