senetti are really an in between plant I think between wallflowers and perennials. Best in spring and they hate hotter weather...I.e. The summer. They need to be watered well because in my experience they fill their pots ...over fill...and will suffer without regular top ups. Just dead head and enjoy them for next few weeks.
i have experimented with senetti to see if they will flower again in summer. They did but as very dumpy and not as attractive. For me they are temporary short term plants for the cooler part of spring.
potentillas are easy enough from cuttings ......for me they vary success wise. Take some now and insert around the rim of small pot. Again try soft wood cuttings in summer
