Gardeners' Notes:

Zone 6B - This variety is the 'Wow' plant in my gardens. It combines nicely with Amaranth Hopi Dye behind it. Yes, it produces a lot of seeds, but I don't find it invasive, I just move the seedlings. The foliage is clean and neat until blooms appear in July, the plants topped out at 4' this year, more like an annual shrub. Again, a two green thumbs up!

These are very pretty and smell great at night! The red "glows"!
They pretty much take care of themselves, and I find it very usefull that they self seed.

It seem to be a herbacious perennial here in my zone. For the plant upon returning its second year and its performance, appear much bigger, stronger than the few scattered seedlings that I've observed. Not at all invasive in MHO, seedlings usually are found in close proximity of the parents plants, thus pulling up is an easy task, and sharing them with others, is a joy. This was given to me as a start; the tradition will continue; pass-a-long plants. (I assumed that this is 'Red Glow' since, the owner that passed this beauty to me didn't know its name). Bright orchid pink?

My Red Glow Four O'clock developed by itself and is a mutation of all the other colors being crosspolinated by nature.
I have white, yellow, light pink, medium pink, fuchia, red, and varigated yellow with fuchia or red.
I think they are all beautiful, and their scent is amazing.

This is my favorite Four O'Clock. The gorgeous color reminds me of fruit punch, and the flowers stay open longer than other varieties I've tried.

It self-sows prolifically, but I don't consider it invasive. The seedlings are easy to pull up, and the plants are not always hardy here in zone 5, although they will survive the winter if planted in a warm location like the south side of the house.

I give this plant a neutral rating because, as beautiful and easy to grow as it is, it is VERY INVASIVE. It self-sows freely and spreads like wildfire. New plants literally sprout up overnight, and within 2 to 3 days are at least 7 inches high. It takes constant vigilance to keep it (barely) under control. But it is beautiful, and you can certainly fill up a lot of empty space very quickly! I "inherited" this plant with a new house, and now I spend more time weeding the 4 o'clocks then I do the weeds!
