It belongs to the same family as the cornelian, but comes from North America; it has the habit of a small tree, or of a medium-sized shrub, even if the growth is very slow, and if cultivated in the garden it takes several years to reach 4-5 meters in height, remaining for a long time below three meters . The trunk is generally single, and has a wide and rounded crown, well branched; this dogwood has oval leaves, dark green, in autumn, before falling they take on an elegant red-brown color. Between the end of winter and the beginning of spring, at the apex of bare branches, it produces small inflorescences consisting of small yellow or green, star-shaped flowers; under each inflorescence develop four large heart-shaped bracts, of a white color. There are some hybrids and varieties, with pink or red bracts; the flowering of the cornus florida is quite ephemeral, but the splendid and elegant inflorescences are worth the months of waiting with the completely bare plant. After flowering the beautiful foliage develops, and in September the small red fruits ripen, also gathered in small groups, at the apex of the branches.
Certainly the water needs of the cornus florida are one of the key elements to obtain a healthy and lush shrub; this plant during the vegetative season, which runs from March to October, needs a fairly humid climate, and therefore if the rains are scarce we will have to intervene watering the plant, especially during flowering and the consequent vegetative awakening. The soil can also dry for a few days, without causing damage to the plant, but it is good to intervene whenever the rains struggle to fall and the soil dries for long periods of time.The cornus florida needs watering at the time of implantation, then we will supply water only in case of absence or scarcity of rain, during flowering, and in the first spring weeks. During the warm months instead the waterings will be more regular, more abundant more the plant receives direct sun.We avoid leaving the cornus completely dry for excessively long periods of time; we particularly insist with watering in the case of specimens grown in pots.Every year, at the end of winter, we dig at the foot of the mature manure shrub, or a slow-release granular fertilizer; if we live in an area with calcareous soil, or with calcareous water, we remind you to provide, at least once a year, a soothing fertilizer.Flowering dogwood - Cornus florida: Land
It needs a rich, deep and soft soil, possibly acid; we will plant it then enriching the garden soil with mature manure and chopped peat; if we live in an area with very calcareous soil, it is preferable to place the cornus florida in a vase, so as to be able to replace the earth of the vase every 2-3 years.
