Gentiana calycosa Pleated gentian

This plant requires a moist, cool soil in part shade. In Parkdale YYC it begins to bloom in mid-July. The striking deep, intense blue colouring makes it conspicuous and it all “All parts of this plant…are poisonous if ingested.”*

Gentians are among the loveliest of mountain wildflowers and are rock-garden favorites. The genus honors King Gentius of Illyria, ruler of an ancient country on the east side of the Adriatic Sea, who is reputed to have discovered medicinal virtues in gentian plants.” (LBJWC)

The City of Calgary recommends Lysimachia nummularia “Aurea” Creeping Jenny as one of its Yardsmart perennials. “This is an excellent spreading groundcover for shady spots and trails nicely over rocks or walls with yellow flowers in midsummer. It does best in partial shade but will tolerate sun and shade as well. It is good for moist locations and a good plant to take advantage of rainwater runoff. It does spread but can be easily picked back by pulling stems out. Helps attract bees to the yard.

By July this stonecrop is flowering in Calgary. It is a robust low matting naturalizer and ground cover in Calgary. It prefers full sun and can survive poor soil and hot sun. It can be identified when it is not flowering by its rounded green leaves. It is great for edging garden beds as it will survive light foot traffic and can be cut back easily even with a lawn mower. It can be easily shared by planting pieces even without roots in April or May.

A robust naturalizer in Parkdale YYC.

I purchased this plant at greengate Garden Centre in Calgary in the fall of 2011 along with a number of perennials that were on sale in late September. This garden bed called September surprise has been consistently productive in every season.

On their website Green Gate Farms in the US describes it as,

“‘Weihenstephaner Gold’ Sedum is among the most popular groundcover sedums with its covering of tiny canary yellow star-shaped flower clusters in late spring. ‘Weihenstephaner Gold’ is a low-growing stonecrop that spreads by trailing stems to form an attractive ground cover. Flowers appear on reddish stems rising above the thick, triangular, succulent green leaves sharply toothed near the ends. The leaves turn purple in fall and into winter. The clusters of star-shaped, yellow-tinted, bronze-orange flowers are very attractive to butterflies and bees. An excellent selection for difficult sites such as banks and rocky areas.”

They also recommend that “Stonecrop be planted in “average, dry to medium moisture, well-drained soils in full sun. Needs good soil drainage to perform well. Avoid over-watering. Drought tolerant. Tip cuttings from plants may be rooted directly in soil around the plants.”
