This is one of the best annuals one can choose for any difficult dry area or problem spot in the garden. Never needs watering and just blooms and blooms and blooms. Such pretty and colorful flowers.

Love this plant and I have great success sowing it in place outside after last frost date. The flowers remind me of the crepe paper parade float flowers. Mine have survived some droughts and my poor watering schedule with flying colors. It's a bit tedious but you can collect seed from them as well.

A student gave me one potted in a little coffee cup, which I set on my windowsill. It lived and bloomed for almost 3 years, until the cat finally knocked it down while we were out of town for a week.

Great for areas with dry or poor soil. Very drought-tolerant, and blooms non-stop without deadheading. Great in the ground or in containers. The fleshy stems and leaves look as if they'd be pointy, but they are actually quite soft.

I really love this plant, especially for areas that are very hot and dry, with poor soil. It is very easy to grow from seed, which is a bonus for me. It also reseeds nicely, which is good if you have it planted in a hard-to-reach area, as I do. The only problem I've had with it so far is that the deer seem to think it is delicious. I've planted seeds three times this year, and luckily it got to blooming size each time before the deer did away with it. I hope some seeds dropped before they ate it! If not, I'll try again next year. Luckily, it's a fast grower and it seems to thrive on neglect.
