Our Mother's Day excursion.
From the www.morikami.org website:
IN JAPAN, flat expanses of raked gravel, with little more than a few well chosen rocks carefully placed here and there, were the legacy of the early Zen rock garden which represented a tumbling waterfall. Laid out beside residence halls at Zen temples, these later rock gardens called ‘dry landscapes’ (karesansui) took abstraction of nature to an extreme never before seen in garden design. Almost devoid of plants, such gardens challenge our Western notions of what gardens should be, while their uniqueness as landscape designs have made them the most widely recognized of all Japanese garden types.
