Here we look at a special plant in a bit more detail to be appreciated by enthusiast and beginner alike.

Stachyurus

Originating from Eastern Asia and the Himalaya there are 10 species of deciduous shrubs or small trees that are hardy to about 15°C / 5°F and lower if shelter can be provided.  The Greek description forStachyurusis “spiked tail” (stachys - a spike, and oura - tail, referring to the shape of the racemes) hintings at its yellow inflorescences of 7cm (2½ /4in) long, which hang down from reddish-brown, leafless branches in early spring. 

The tiny, bell-shaped flowers are formed in the previous year, and mature during autumn before leaf fall.  Dependant on the weather they do not open until late winter or early spring when these flowers have a purity of its colour that shines out and brightens up any dull grey winter’s day!

After flowering prune to remove dead, diseased, crossing or weak wood at the base; do not fear it soon regenerates so be prepared to thin out any overcrowded specimens.  The strongest stems of wall grown shrubs should be tied in after flowering, re-organize the framework regularly using young growths from the base.

Stachyurus praecox from Japan needs sun or partial shade plus shelter above all in cold areas where it can be trained against a wall so that the flowers will not be damaged by frosts.  It will grow in any soil, but it prefers cool, humus-rich, acid soil and it will tolerate lime.  It can reach 2m (6½ft) tall with a spread up to 3m (l0ft) and will be an interesting addition to your garden it is readily available from garden centres and nurseries. 

The species Stachyurus praecox is hermaphrodite (def: bisexual, having both pistils and stamens in the same flower) but there is a selection called Stachyurus praecox ‘Gracilis’ which has female flowers. 

Stachyurus praecox var. matsuzahii has thicker, pale green stems and larger leaves and the yellow flowers open later in mid-spring and should only be grown in mild climates.

Stachyuruschinensis from China is more spreading than in S. praecox and its pale yellow flowers open later.  For a novelty the variety ‘Magpie’ has leaves which are grey-green above, spotted pale green or pink, and has an irregular ivory edge below.

To increase stock, propagate using fresh seed, by layering or by heeled semi-ripe cuttings in a closed case or under mist with gentle bottom heat from mid-summer to early autumn
