It is noted for attracting wildlife.
Suitable for: light (sandy) and medium (loamy) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils and can grow in very acid soils.
It cannot grow in the shade. It prefers moist soil. The plant can tolerate maritime exposure.

Habitats

Woodland Garden Sunny Edge; Dappled Shade; South Wall. By. West Wall. By.

Edible Uses

Edible Parts: Nectar.
Edible Uses:

The flowers are rich in nectar and this is sometimes harvested as a food. It is best harvested in the morning before birds and evaporation deplete the yields[193]. The flowers can be sucked or soaked in water in order to obtain the nectar[193].

Other Uses

Rootstock;  Tannin;  Wood.

The bark contains about 10% tannin[46, 154]. Used as a rootstock for other members of this genus[200]. Wood - soft, easily worked, pinkish with a prominent grain. It is highly decorative but the plants tend to be gnarled and irregular thus limiting its use. Used for veneers, furniture etc[154, 167].

Cultivation details

Succeeds in most soils[157]. Requires a lime-free soil[1]. Thrives in acid sandy loams[167]. Prefers a pH between 6.3 and 6.5[200]. If this species is to be successfully cultivated, the soil should be low in nutrients, especially in nitrates and phosphates[200]. Quite resistant to wind and salt spray, it grows well by the coast[166, 200]. Plants growing in exposed positions have entire leaves whilst those in sheltered positions have serrated leaves[154]. Plants require greenhouse protection in most parts of Britain[1] but they succeed outdoors on a sheltered wall in the mildest areas of the country[166]. Plants in Australian gardens tolerate temperatures down to at least -7°c[157], but this cannot be translated directly to British gardens due to our cooler summers and longer colder and wetter winters. A polymorphic species, there are many named varieties selected for their ornamental value[200]. A good bee plant[154, 167].

Propagation

Seed - surface sow in an ericaceous compost as soon as the seed is ripe or as soon as it is obtained and do not exclude light. Seal the pot in a plastic bag until germination takes place, which can take 1 - 3 months or more at 20°c[134]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, July/August in sand in a frame[200].

This species contains three subspecies: B. integrifolia subsp. integrifolia, B. integrifolia subsp. compar and B. integrifolia subsp. monticola. It is worthy to point out that B. integrifolia subsp. monticola is the most frost tolerant, it grows at altitudes between 650-1200 (1500 m) above sea level, given its montane distribution B. integrifolia subsp. monticola tolerates colder temperatures than those described in this text, there is healthy plant of this subspecies has bloomed and is growing outdoors at Sir Harold Hillier Gardens, England.

Why is it resistant to wind and salt spray?
