Cliff Edge

Lilacs grow richly on the cliff edge -- and only on the cliff edge! -- and make quite a display for passersby on the highway below. During their brief springtime bloom, I get an armful or so for the house and porch and giveaways to the benighted who do not have lilacs. (How they got up here in a sand glade I don't know.) They rank with bluebirds and crocuses as one of my favorite things and one I will crawl onto a cliff edge for. Who wouldn't? As long as I can, I will, and I would grieve if I didn't.

This time the usual approach to the cliff edge was overgrown, already, with leafy understory junk shrubs and vines. Up a slope of tall grass with bits of sandstone gravel imploding under my treads, shouldering past an electrical pole, stepping over fallen logs and a patch of prickly pear cactus growing in a sandy microclimate one foot square -- never know what you'll find around here! -- keeping my balance, some lilacs were within my reach. The greater part of the display just swayed in the wind and laughed.

Lilacs are not Missouri native plants or even North American. They're from Eastern Europe and Asia. To whoever sneaked them over here, thank you, and I understand you completely.

Growing in a Micro-Climate

Missouri's in the temperate zone, but in some dry rocky south-facing sandstone glades that get a lot of sun, cheerful in the huge long drought grow cacti like these prickly pears (opuntia humifusa). I haven't seen any other type of cactus in this area. What's a "glade," you ask? A rocky outcropping amidst woods or grassland. Our glades here are sandstone. The cacti grow in just-right areas only a few feet square called "micro-climates." This one's on the sunny side of the road. The opposite side, chilly and shadowy, is an entirely different ecosystem, supporting temperate plants and creatures and moss and no cacti.

I find cacti on the edges of woods here, at the base of dry south-facing sandstone formations, and on the edge of my south-sloping gravel driveway, where prickly pear plants like shoe soles have persisted for years despite being snowed on, frozen (they turn purple), stepped on, bruised, and run over by cars. If not, they produce frilly yellow blossoms and plum-like fruits. Always get a pleasant sense of wonder when seeing  these wise and witty-looking desert entities way up in the Ozark foothills.
