Hydrangea macrophylla "Madame Emile Mouillere"

These plants grow well in sun or in partial shade. Usually they tolerate more sun and heat if given enough moisture; in partial or light shade they need less moisture.

Decidious have woody stems (i. e. tree trunk and branches) and are also called woody plants or trees. Leaves are normally broad, soft and thin.

This group includes plants that cannot tolerate limestone (chalk) and need acidic soils to grow normally, this is soil, of which pH must lower tahn 6. According to pH value (acidity and alkalinity), soil can be either acidic, neutral or alkaline, with intermediate levels. Fertile, quality garden soils of most gardens and parks are  slightly acidic to neutral (pH 6-7) and suit most of plants. If soil contains a lot of calcium (limy soils), it is alkaline soil. Acidic soils contain much less calcium, they can be richer in humus. Some acidic soils are washed out and poor in plant nutrients. Plants like, for example most of the rhododendrons, heather, camelias and bluberries, grow normally only in distinctively acidic soils, so such soil must be attained when planting. Most of other plants do grow well in slightly acidic soils, but grow as well also in neutral soils with a bit higher calcium content.

The plant develops new leaves or needles every spring, which dropp off in autumn. Herbaceous plants can die completely in above ground section and grow back in the spring.

Plant can in otherwise appropriate environment survive cold down to - 23 °C.

Porous or dry soils are normally light and loose, there is no stagnant water but relatively quickly flows in deeper layers; such ground are more airy and warmer, yet drier and usually contain less humus and for such undergrowth it is often to for drought to appear (e. g. rockgardens, walls, by paths and roads, on gravel, also on gravel surface in towns and close to buildings ...), plants of such undergrowth need well-drained soil, they tolerate drought but cannot tolerate constant moisture or even flooding.

Woody plant, normally branched at the ground level into several side stems, usually lacks of a dominant stem. Tree top can be of different shapes, dense or thin, symetric or uneven. Most shrubs reach a height of 1 to 2 metres, but some can grow much higher (up to 8 m); some can grow into very low or carpet-like forms.
