Product information "Yellow Groove Bamboo 'Spectabilis'"

Phyllostachys aureosulcata 'Spectabilis' is very conspicuous and decorative due to its striking canes and the zigzag growth in the lower part.

In the lower part of the cane, the yellow groove bamboo 'Spectabilis' has an interesting, zigzag habit. The canes are yellow; they turn reddish in the sun and have a green stripe from one cane thickening to the next.
Very decorative zigzag growth

The bamboo 'Spectabilis' lives up to its name. The sprouts often start to skew at the beginning and then straighten up and grow in the opposite direction. This spectacle is repeated a few times until they finally grow upright and straight. The canes are yellow and often reddish in the sun. The “groove” part of the name is also taken into account, with one green stripe grows from one cane thickening to the next. The canes are quite thick with a diameter of 4 cm; they grow upright and the tips are slightly arched to overhanging.
This bamboo is hardy to -24°C and prefers a sunny to partially shaded location. In the sun, the canes have a pretty, red colour. The soil should be nutritious and permeable and as with all bamboos, uniform moisture is preferable and they do not endure waterlogging well.

Phyllostachys aureosulcata 'Spectabilis' is a very decorative bamboo. In order to bring out the beautiful zigzag growth in the lower part, the lower part can be trimmed. Also, the bamboo can be regularly cut to a height to make an evergreen hedge, but the decorative canes won’t be as attractive.
Avoid the mistake of not installing a rhizome barrier

All Phyllostachys species form rhizomes, vigorous rhizomes. If one lets the formation of rhizomes get out of control, the bamboo can soon grow into the neighbor's garden. In order to avoid unnecessary problems with the neighbour and to save a lot of work, it is indispensable to install a rhizome barrier. And believe me, I grew up next to a property with a beautiful bamboo forest. And if our parents had more trouble with us children than with the neighbour, as punishment we had to remove the strong growing bamboo in our garden. Only with a very stable spade could you cut out the rhizomes and then we had to dig and dig and dig again in order to remove the last remains of the bamboo rhizomes. If you were not thorough, it could happen that the next day new bamboos grew in the garden. At this point, my parents were sometimes so annoyed (both by us children and by the neighbour's bamboo) that they told us horror stories from Asia. There, people would be tortured by tying them outstretched on the ground so that they would be spiked with bamboo shoots within a day...After such stories, the evil canes were then removed very quickly.
With this story I would like to make clear that a rhizome barrier is indispensable for sprawling bamboos. This barrier must consist of a thick and durable plastic and reach about 1.5 m in depth. In addition, it should rise about 10 cm above ground level. This is the only way to prevent the rhizomes from growing under or over the barrier.
It is best to surround a space of at least 10 m² so that Phyllostachys aureosulcata 'Spectabilis' can develop and a loose bamboo grove can be formed. Despite the barrier, it should be checked at least twice a year, if not some rhizomes have escaped and these should then be removed immediately. Inside the barrier, one can regularly remove the oldest canes, thus making room for the young shoots. By the way, the young, tender bamboo shoots can be used in the kitchen. So you have a double benefit if you regularly remove the canes. The old canes are very decorative and can be used for crafts; the young sprouts can be processed into a delicious, Asian dish.
And the flowers?

Maybe you already know that the bamboo blossom is a pretty mysterious thing. It takes place only about every 100 years and then all specimens of a genus bloom within 10-15 years. Many bamboos die off after flowering. The Phyllostachys varieties have been in bloom since the 1990s. However, no germinable seeds have been formed and reports that mature plants have died have not been confirmed to date. If your Phyllostachys bloom, then the flowers should be removed as soon as possible. If the bamboo then weakens, it can be cut radically and fertilised well. This gives the bamboo additional energy to recover.
