noun
A low-growing juniper variety (Juniperus chinensis var. procumbens) often used as ground cover in Japanese gardens.
庭のハイビャクシンがきれいに広がっている。
The dwarf Japanese garden juniper in the garden is spreading beautifully.
The name likely derives from 這う (はう, 'to creep') + ビャクシン (柏槇, 'Chinese juniper'), referring to its creeping growth habit. The exact historical derivation is uncertain.
