Primula

Primula 'Arduaine' ? £4
This lovely petiolarid with icy blue flowers in very early spring, clustered in the bowl of a farinose rosette, came to us as P. whitei. We find it entirely growable in pots in a cool position here in South Devon. As far as I can tell, it must be the hybrid with P. bhutanica, named 'Arduaine' (pronounced Arrdoony, I believe), although in our inexpert hands it doesn't quite make the bowlfuls of blue soup you sometimes see on the AGS showbench.
Primula 'Barbara Midwinter' £4
On the scale of a primrose, with deep carmine flowers with well separated petals, through the winter. Distinctive leaves. Really special. juliae x (megaseifolia x juliae).
Primula 'Blue Riband' £3.50
A compact primrose with large violet blue flowers in spring.
Primula 'Clarence Elliott' £3.50
Perhaps the most satisfactory allionii hybrid: vigorous and floriferous. Large lilac, yellow centred flowers in early spring, glaucous leaves. Alpine house or perfectly drained sink.

Primula Cowichan polyanthus:
We're not plant snobs, honest guv. A good polyanthus is a lovely thing, especially when used for its colour and form rather than in a jazzy bedding scheme. Barnhaven's Cowichan seed strains with their prolific, normal sized (i.e. not blowsy giant) flowers with only small yellow eyes are great, but almost uniquely in the nursery trade we go on to select elite clones and propagate them vegetatively, taking care not to transmit virus in the process.

Deep plummy violet-blue.
Primula Cowichan Garnet £3.75
Selected for good deep red-brown with tiny eye.

A distinctive old poly. The deep violet blue, yellow eyed flowers hang slightly on long pedicels. Choice.
Primula x pubescens 'Christine' £3.75
A robust hybrid auricula with red-purple flowers, growable in the open garden. I'm not a huge auricula fan, but this is lovely.
Primula sieboldii 'Duane's Choice' £4
A brash American dude. It's the one of the best clones of the sort which has dark backs and pale fronts to the divided petals, in this case a strong purple pink back giving excellent contrast. The flowers are large, and the edges of the petals tend to curl forwards, showing the backs. All our sieboldiis are propagated vegetatively. They go down to underground crowns in winter. Drought is their enemy.
Primula sieboldii 'Dart Rapids' £4
We've taken pains to select an equally good, but far more refined and English counterpart. Again it has a pale face and strongly coloured reverse, this time in very pale / really deep lavender, and with entire petals.
Primula sieboldii 'Pago Pago' £3.75
This name refers to a seed strain, of which this is a selected clone. Moderately sized flowers of an intense magenta-pink, not at all frilly.
Primula sieboldii 'Snowflake' £3.75
Pure white and very feathery.
Primula 'Sir Bedivere' £3.50
Little primrose, dark purplish red flowers with starry yellow eye, red petioles.

You can thank, or blame, Dan Heims.
Primula 'Tomato Red' £4
Depending on the weather, the colour is of sliced or whole tomatoes, at varying stages of nearly-ripeness. A floriferous primrose, which is unambiguously attractive, despite any other impression my attempts at accuracy might convey.
