The Densiflora section, also known as Callista, with short, thick, strongly keeled pseudobulbs, which terminally bears leathery and thick leaves, also includes species that will require winter rest, but without losing their leaves. The species in this section stand out for their cold tolerance, temperatures of 3 - 10 ℃ being considered the triggering factor for flowering. The species belonging to this section are chrysotoxum, farmers, griffithianum, jenkinsii, lindleyi (syn. aggregatum), palpebrae, sulcatum, thyrsiflorum, all preferring medium or high temperatures, only the densiflorum species being lovers of lower temperatures

Similar to many other types of orchids, the phenomenon of wintering is also present in the species of the genus Dendrobium, but not in all, and it does not manifest itself in a similar way. For the uninitiated, the general tendency will be to treat all Dendrobium species in the same way, however, it should be noted that the heterogeneity of this genus is not only at the anatomical level, but also at the ecological level, especially in terms of preferences for the growing climate and its seasonal variations. This aspect is best summarized by dividing the genus into sections, which group species with similar appearance and preferences.

The complete offer of Dendrobium from Secret Garden is available here (link).

Section Dendrobium, which groups species such as anosmum (syn. superbum), aphyllum (syn. pierardii), chrysanthum, crystallinum, fimbriatum, friedicksianum, gibsonii, heterocarpum, linawianum, loddigesii, moschatum, nobile, parishii, primulinum, pulchellum, schulleri, senile , signatum, stricklandianum, unicum, wardianum, falconeri, findlayanum, moniliforme, characterized by a preference for high to medium temperatures, except for the last three species, and a resting season during the winter, when the plants will lose their leaves and at least partially their roots , keeping only the characteristic pseudobulbs, reminiscent of the appearance of reeds, which will appear more or less dry and shriveled. These aspects should not surprise or worry breeders, being a common moment in the biology of these species. The plants will resume their growth once the spring season arrives.

During the winter period, it is recommended to decrease the frequency of irrigation until they stop completely, until the moment of the appearance of flower stems, when you can resort to occasional sprays, but without suddenly changing the water regime.

Given the abundance of species of horticultural interest belonging to the genus Dendrobium, the complexity of hybrids should not surprise us. On the contrary, before deciding on the purchase or care method for the preferred specimen of Dendrobium, it is recommended to thoroughly document the parental composition down to the species level of the plants that attract our attention, then checking how many of the respective parents belong to which sections, in order to be able to identify the optimal way to care for them.
