Alpine Wintergreen. Our collection as cuttings of this little groundcover growing on the shores just above waterline at a montane forest lake in northern California. Seldom encountered for sale despite being distributed across the western US and Canada. White flowers with a red calyx followed by red fruit.  This has been easy-peasy for us and enjoys an airy moist soil high in organic matter.

Choice dwarf form of the former Pernettya mucronata from a Vojtech Holubec collection at Torres del Paine, Chile above treeline.. This little evergreen gets 6"-12" tall with small white flowers and white to lilac berries. Gently rhizomatous and a good rock garden candidate liking acid soil. Thanks to Ben Kamm for making this goody available.

Very dwarf little creeping Gautlheria from wild collected seed in Arunachal Pradesh.  This prostrate shrublet can have oversized fruit of pink to white to blue and in this form. the berries are whitish tinged in pink.  If you lived in Scotland and had a peat block wall, this would totally grow there but since you don't, a partly shaded rock garden will suit.

Former bigeneric hybrid with Pernettya until they merged Pernettya into Gaultheria.  This is from a plant from Art Dome. late collector of choice Ericaceae in Seattle.  Art said this has larger fruit than the typical G. x wisleyensis.  Nice black fruit and white-pink flowers.  Good drainage,
