Black locust is a reliable and hardy tree of our climate. It is a maintenance-free plant which makes it ideal for city parks and places where garden care is limited.

i>Umbraculifera is a popular variety of locust with 25-30 cm long pinnate, deciduous leaves that are made of up to 23 elliptic to ovate individual dark green leaflets. New leaves appear all season long so there are always some new at the tip of the branches, looking really fresh. An exceptional advantage is the fact that the leaves, especially in towns and cities, remain on the tree until very late – often until December when the first serious frosts come. It does not flower and therefore makes no mess from fallen flowers.

It is called mop-head acacia because of its smaller, compact crown which needs no pruning whatsoever to maintain its shape. The crown usually grows about 2m both high and wide which makes it ideal for small gardens and narrow streets. Pruning is recommended only if you need to keep its size smaller. It can be done from end of winter until beginning of summer.

The tree is very healthy, disease- and pest-free and tolerates air pollution. It adapts to almost any soil type except wet. Fully hardy to min. -34°C (USDA one 4).
