Classic gesneriaceae - sturdy basal rosette of fleshy crinkly leaves and stems of foxglove like flowers emerging from the centre. The flowers are a very striking bright yellow, deep red inside, and the leaves are purple on the reverse. Not well tried outdoors in the UK, but the main problem overwintering temperate gesneriads usually is not the cold so much as keeping them dry in winter, This doesn't seem to be a problem in this case.
Titanotrichum is best in a moist woodsy soil, and it is imperative that it does not dry out in summer, or else the flower buds will turn to tiny tubers (gemmae). A solid and vigorous woodland perennial as long as it has enough water
Another North American that certainly deserves to be better known. Forms colonies of upright stems with fresh green rounded leaves ultimately developing an almost Euphorbia-like inflorescence of tiny white flowers subtended by silvery white bracts. At this stage the whole plant has a pale silvery sheen.
Not invasive. Has a lovely fresh peppermint fragrance too, and can be used in the same way. Any soil.
