Chojubai (dwarf flowering quince)
BeginnerChaenomeles japonica 'Chojubai'
A dwarf cultivar of Japan's native Chaenomeles japonica—despite the 'ume' (apricot) in its name, it is a flowering quince. Repeat-flowering, mainly in spring and autumn, with single scarlet and other coloured blooms, it is a favourite for small bonsai.
About
Chojubai is a dwarf cultivar of Chaenomeles japonica, the flowering quince native to Japan, and one of the most popular flowering bonsai; some treat it as a variety. The name contains 'ume' because the flowers resemble apricot blossom, but it is not a Prunus. It is also a different species from the common flowering quince (C. speciosa); Chojubai is smaller overall and stays compact even in the ground. Its hallmark is repeat flowering: given the right conditions it blooms through much of the year, most heavily in spring and autumn. Flowers are single with five petals, typically scarlet, though red- and white-flowered plants are also sold under the name. The spatulate leaves have conspicuous teeth; being semi-deciduous it may yellow and drop its leaves several times a year, but new shoots follow quickly. If left, flowers set fragrant fruits 3–4 cm across that tax the plant, so deadheading is standard. Leaf and flower size vary between plants, and those with fine twigs and leaves are preferred for bonsai. The stems are thorny. From rooted cuttings to finished mini bonsai, it is among the most widely sold flowering bonsai in Japan.
