For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea

Irregulares section saxifrages are shade-tolerant, usually herbaceous perennials forming rosettes broad, palmately lobed leaves, with leafless stems bearing lax panicles of small flowers with short upper, and longer lower petals, in summer or autumn
