Plectranthus, Isodon, Rabdosia and so forth

Rabdosia longituba
Despite the indecision over the names, a splendid, if understated group of hardy late flowering perennials - adaptable but at their best in moist semi shade.

Plectranthus excisus
Plectranthus excisus
A succession of violet labiate flowers in long slanting racemes in late summer and autumn. The foliage is unusual in shape with dark purple tints. 
Plectranthus excisus
Very adaptable and fully hardy here
£8


Rabdosia longitubus
Isodon longitubus
Clear blue flowers over a long period from late summer onwards. The flowers really glow in the low autumn light like tiny gas flames. Any soil in sun or semi shade. Easy but may not emerge until May or June.
£8
