Gardeners' Notes:

I live in Vancouver Washington (zone 8b) and I have a couple of these in my side yard. I have them left and right from a small Crape Myrtle and I water the CM but not these Chrysanthemums. But they seem to get enough water from when I water the CM.

I am getting impressed with these because here it is early November and they are in full bloom, when not a lot else is in bloom. I'm planning to plant some more.

I got this plant in 2010 by accident from some mail order plant company. I actually almost threw it away but decided to give it a chance and planted it. The plant spreads nicely on it's own. It seems to have two main bloom pushes; one in early summer and one in late summer. I very much like it's 'naturalizing' habit. It can be a little floppy but only partially so. Mine gets morning sun and then bright shade the rest of the day.

A single, daisy-like, mid-pink flower, this was the first of Amos Perry's "rubellum hybrids", released in 1939 and still one of the most popular garden chrysanthemums today. I find it exceptionally valuable for its exceptionally early and exceptionally long season of bloom.

In commerce, this is frequently confused with other garden mums. For example, if you look at the 18 pictures currently posted in this plantfile, how many different cultivars can you distinguish?. Fewer than half of those 18 show the plant I know as 'Clara Curtis'.

Garden chrysanthemums (including the "rubellum hybrids"---a trade name rather than a botanical one) are distinctly different from the "hardy mums" commonly sold in garden centers in the fall for bedding. For garden chrysanthemums ... read more

I like this plant. It is a groundcover and spreads, so plan carefully where you want to put it. Easy to weed out and keep in bounds. Needs pinching back (or shearing) two or three times during the summer to keep it from becoming leggy. Good in humid climates where other Chrysanthemums' big double blooms turn black with mold after fall rains.

Very floppy and spreads like crazy. Not desirable traits in the location I have her in. The flowers are charming and abundant during a time when gardens can start to look a little tired. Perhaps in the right setting she would be a keeper, but I am on my way outside now transplant her to a pot and think about what to do with naughty Clara.

Easily grown mum needing only pinching back once or twice during the summer to prevent flowering too early and light shearing after blooming.

In our neighbourhood in late fall most of the gardens look a little sorry. One neighbour has a garden full of Clara Curtis, and her garden is absolutely gorgeous in fall. I plan to get some next year for late fall color. This aster is much more attractive than mum's, in my opinion.

This plant is just too spready... and too floppy for me. It grew so fast I needed to pull handfulls out every year. The late color is nice but it always flopped and looked messy. It tried cutting it back early in the season but that didn't seem to help much. I gave her a chance... She's a goner now.
