Japanese Maple 'Bloodgood' (Acer palmatum) - with fiery foliage - 26 cm pot - Height 90 cm

Yes, the Japanese Maple 'Bloodgood' (Acer palmatum 'Bloodgood') is one of the most frost-hardy cultivars among Japanese maples. It can withstand temperatures down to -15°C, allowing it to overwinter in the ground in almost all regions of France without any special protection. Its main vulnerability lies with the buds and young shoots in spring: a late frost after bud break can scorch the new leaves without killing the plant.

T'he Japanese maple 'Bloodgood' t'hrives in partial shade or light, dappled shade. An east-facing position, sheltered from the scorching afternoon sun, is ideal: it receives a few hours of soft morning light, which intensifies the purple colour of the leaves. In full sun, especially in the south of France, the delicate leaves can scorch at the edges and lose their rich colour. 'Conversely, too much shade dulls the colours and further slows its already sluggish growth.

Acer palmatum 'Bloodgood' is a slow-growing tree: it gains an average of 20 to 30 cm per year in good growing conditions. This slowness is precisely what makes it a valuable specimen in the garden: the silhouette is built over years, the branches branch out finely and the plant never overflows into neighboring spaces. At maturity, 'Bloodgood' can reach 4 to 5 meters in height and a comparable spread, but this takes several decades.

J'apanese Maple 'Bloodgood' requires fresh, well-drained soil that is slightly acidic to neutral, with an ideal pH between 5.5 and 7. Heavy, waterlogged soils should be strictly avoided, as root asphyxiation is fatal in the medium term. Very alkaline soils cause iron chlorosis: the leaves turn yellow between the veins, weakening the plant and marring its appearance. To improve ordinary soil, incorporate a good volume of leaf mold or mature compost at planting, as well as coarse sand if the soil is clayey.

J'apanese Maple 'Bloodgood' lends itself very well to growing in a large pot or container on a patio or balcony, provided you follow a few essential rules. Choose a container of 'at least 50 to 60 liters, with good drainage at the bottom (clay pellets). Use a mixture composed of two-thirds quality slightly acidic potting soil and 'one-third ericaceous soil. Place the pot in partial shade, sheltered from the wind and the 'afternoon sun.

The dark purple foliage of the 'Japanese maple 'Bloodgood' creates striking contrasts with chartreuse or silver-foliaged plants. Hostas, especially large-leaved blue or yellow-green varieties, form a classic and highly effective duo in 'shade. Ferns (Dryopteris, Athyrium) add lightness and texture at the base of the 'maple. White or pink astilbes reflect the light under the canopy and offer complementary summer blooms.

T'h Bloodgood 'Japanese maple' can be planted in the ground at two ideal times of t'he year. Autumn planting, fr'om October to November, is often preferable: mild temperatures and autumn rains promote root establishment before w'inter, and t'he tree vigorously regrows in spring. Spring planting, from March to April, is also possible once the frosts have ended, but then requires regular watering throughout the first warm season. Avoid planting in midsummer or during heatwaves, as water stress can be fatal.
