Large, fast growing, frost tender (min. +10 °C), evergreen climber (H 5-8 m, depands as well on staking, W 3-5 m). Stems woody at the base. Leaves with long petioles, broadly heart-shaped (20-25 cm), smooth, mid green. Flowers broadly funnel-shaped to tube-shaped (15-18 cm), variegated, dark violet, pink-red to light green. Flowering period: June-July. Grows well in nutrient-rich, always moderately moist, humus-rich soils in sun or semi-shade. Not hardy in central-european continental climate, best grown as a container-plant.
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.
Leaves or needles remain on the plant for several consecutive years, usually 2 to 5 years. Our descriptions contain the word evergreen.
Plant is cold/frost sensitive, mainly cannot survive temperature below freezing point (0 °C) or requires significantly higher temperature to live (e. g. some tropical plants). Required minimal temperatures for certain plants are given in detailed descriptions.
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.
A plant that requires support to grow in height. It can attac to support by special adhesive roots, or twist the stems around the support. We help them to climb with ropes or wires. Climbers may be woody or herbaceous, evergreen or deciduous, they also have different life cycles. Woody climbers are normally included in group of shrubs, the herbaceous ones on the other hand are grouped with annuals, biennials or perennials, according to their life cycles.
