Weather: Another week of broken promises with polluted air, high temperatures and lying clouds that leave no rain; last rain 07/08/09; 14:14 hours of daylight today.

Weekly update: The rarest thing of all is a plant that grows as advertised.

Take speedwells. Back when I was buying plants in Michigan, Wayside Gardens said they’re "among the most useful of hardy perennials. By judicious selection, you can have flowers from June through September. The neat, compact plants are beautiful, even when not in bloom."

Lamb Nurseries called them "underrated" and of "outstanding importance" before adding they "bloom with such abandon that we rank them among the choicest of low-growing plants."

Well naturally I gave them a try, and nothing happened. Most of the plants didn’t survive, and those that did only filled space.

I’m not sure now why I ordered some plants for here in 1998, other than desperation to find something blue. I no longer took comments like those from White Flower Farm that Goodness Grows was "the best of the lot" that "blooms forever." I just knew it wasn’t the same cultivar I’d tried before.

The next two summers the young plants bloomed from late June until late July, then either didn’t flower or only put up a few short spikes for a few weeks. This year, the long, narrow flowers started opening at the base June 20, and only now are the last flowers appearing at the top of spikes that have lengthened to 4" on stalks up to 11" tall.

They haven’t reached the size promised by growers, a foot or more in height above mats that spread 18", but this is northern New Mexico. The rhizomatous roots have crept along the soaker hose on the west side of the house as far as there’s enough water, but no more than 3" on either side.

The little plant does have its wayward side. Marc Richardson and Rick Berry discovered it growing in a trial garden at their nursery in Lexington, Georgia. Michael Farrow has since patented a pink variety he found in 2003 in his Holly Hill Farms bed in Earlville, Maryland.

The Missouri Botanical Garden believes Goodness Grows is a natural cross between Veronica alpina 'Alba' and Veronica spicata that combines the compact size of the one with the tall racemes of the other.

Since no spicata variety ever grew for me, I think the perennial took its adaptability from the alpine parent. This past winter we had rain in late January that lingered as ice until the first of March. I suspect something in those unusual conditions is responsible for the number and size of this year’s spikes.

Dirk Albach has been particularly interested in the relationship between the great glaciers and the eight alpine Veronicas within the figwort family and found variation within this species existed in the European Alps and that adaptions to conditions had occurred multiple times. He confirmed the suspicion that alpine plants have larger genomes that somehow translate into better "growth by cell division conducted in the preceding favourable season and cell expansion early in the season at low temperatures."

Why a glacial plant would survive in an arid mountain valley in New Mexico is probably related to its adaptability. In central Scotland it grows near the snow line on the sides of mountains where "reflected heat is greatest." However, when it was taken to the 800' piedmont of Georgia it crossed with a spicata.

I suspect that if our weather returns to what passes for normal, the flowers will be fewer next summer but the dark, elliptical leaves will continue to stop grass and other weeds from emerging. That ability alone is rare in a groundcover, and worth having.
