Symphony Orchestra Hibiscus

Hibiscuses, still known in our country as the Chinese rose, have long ago changed their status from a purely indoor plant to the title of one of the most fashionable flowering crops for garden design. Hibiscus seedlings are almost as widely available today as the various rose varieties. Species hibiscus are actively replacing hybrid hibiscus plants that can overwinter in the open ground even in the midlands. It’s not so easy to grow garden hibiscus, but all the efforts and care, and the choice of suitable location and covering will be repaid by a unique sight of huge gramophone flowers on the lush crown.
Frost-resistant and not so hardy hibiscuses
Hibiscus in the conditions of the average strip are grown as:

A perennial for open soil with shelter;
annual plant;
perennial in caddy form or with digging for the winter, which with the onset of cold weather is removed to light cool rooms.
In the latter two roles you can grow Chinese hibiscus or Chinese rose (Hibiscus rosa-sinensis), Syrian hibiscus (Hibiscus syriacus), marsh hibiscus (Hibiscus moscheutos), and herbaceous hibiscus trionum, northern hibiscus (Hibiscus trionum).

Only two types of hibiscus, the hybrid hibiscus and some varieties of Syrian hibiscus, often called the garden hibiscus, will survive outdoors without problems. It is not always the case that the Syrian hibiscus is a tree shrub and the hybrid hibiscus is a herbaceous perennial. The distinction between the two is now being erased, since the winter-hardy Syrian species also lend themselves to hybridization and are obtained selectively. Therefore, it is legitimate to argue that only hybrids can winter in the soil in the conditions of the average strip, but the origin and the specific species name are not as important as the form of growth – shrub or herbaceous. When buying, it is more reasonable to be guided by the nature of growth. Powerful root tubers of hybrid hibiscus persist under minimal shelter even in very severe frost, the above-ground parts – only for tree and shrub forms under shelter.

Hibiscus trifolium is often attributed to sufficiently frost-resistant species, but it can be planted only if you buy adult plants already adapted to your region.
