Gardeners' Notes:

Neutral hamptons On Apr 17, 2013, hamptons from Watermill, NY wrote:

I have "Party Girl." It's a pretty plant, but it only blooms for about a week and a half. Looks great when it does bloom, but I'd prefer something longer blooming. When I deadhead, I only get a sporadic single bloom here and there which isn't worth the effort. I'll say this, it is reliable. I've had mine in the same sunny spot for about a dozen years and it always comes back.

Neutral Lilithanne On Jul 11, 2010, Lilithanne from Pittsburgh, PA wrote:

I ordered Sidalcea hybrida 'Brilliant', which was supposed to be a deep rose-red color. The plant bloomed a sort of mauve-magenta, which I've already had and didn't particularly care for the color.

I've also planted Sidalcea 'Elsie Heugh', which was to be a pale pink color. The first year it was a beautiful pink but the next year it came up the mauve color I mentioned above.

I've given this plant a "Neutral" rating because it does grow and flourish but isn't true to color.

I too love this plant. I have had it for years, it does not seem to spread or self seed for me. That may be because I have it in bright sun in a spot where it gets dry easily. I do find that the Japanese Beetles love it as much as I do. But I knock them off into a container of soapy water to take care of them.

I really love this plant. This will be my third year growing it. It has pritty magenta flowers; it is about a foot high. Ive seen hummingbirds at it a few times too. Likes moist soil in part sun.

I love this plant -- it's well behaved, compact and has come back reliably for three years and looks great ... I intend to get more! I mulch my beds heavily and so no reseeding for me ... maybe I'll give it some room to reseed!

Pleasant well behaved plant. It does reseed itself, although not really a spreader. I have moved this plant many times and it looked like it died - but it never did.
