Gardeners' Notes:


On Oct 20, 2014, coriaceous from ROSLINDALE, MA wrote:

Much like G. psilostemon, but with somewhat softer flower color.

In 2005, the Royal Horticultural Society granted this plant its coveted Award of Garden Merit.

In the Chicago Botanic Garden's hardy geranium performance evaluation, this cultivar received a rating of "poor" (one star of a possible four).

A hybrid (G. endressii x G. psilostemon) bred by Alan Bremner in the Orkney Islands, Scotland.

The cultivar name is 'Brempat'. "Patricia" is a proprietary trade name.

Bought this from Breck's nursery in 2010 as a baby plant. It didn't grow or flower last year. I was afraid it would die. It didn't look good. This year it looks great and has been flowering for a week or two. It is 3 times the size of last year and looks very healthy. I bought a set of 5 geraniums from Breck's and none of them flowered last year or grew, but this year they look real good. They were a variety pack. We are in zone 5b with heavy clay soil that I amended around the base of plant and heavy snowstorms in winter with no protection. They didn't seem to mind that, at all.

An excellent plant. Patricia is tall for a geranium. Lovely foliage. Leaves are fairly large. Her magenta blooms have a star shaped black center. She has a nice long bloom time.She doesn't self sow for me so this is a great plant to have if you want it to stay put! She has held her own quite well against anemone 'Robustissima', which quite vigorous.This is a super low maintainance plant.

'Patricia' is an extremely good hardy geranium; very large and upright, with the most extravagant bloom throughout the season. Hardy and undemanding in zone 3, Calgary, Alberta, Canada.

For me, this plant is quite tall and open, it looks its best growing among other plants. It does not act as a ground cover as some of my other geraniums do. A nice plant in the right spot.

A beautiful hardy geranium of substance with eye catching flowers. One of my favourites, it is an easy grower.

In the spring the foliage is chartreuse. The large flowers are magenta with dark centers and bloom over a long period of time. They are an easy geranium to cultivate.
