There are annual and perennial plants. Some look great, but are not to be planted in some areas, because they simply will not look right there or because the conditions are not right.
Unwin’s dwarf dahlia got nice paper flowers. Bad thing is I will not grow it again. It’s not so easy to keep it happy around here.
Gomphrena is nice, but spreads in all directions, and I didn’t like it.
The vincas below are the ideal choice for next’s year in mass planting. After experimentation I realized they are the cheapest and longest duration annual plant. In reality it’s not an annual, but a tropical perennial from Madagascar. While marigolds, zinnias, portulacas and some others turn ugly after three months, vincas keep their shape the whole year.
I grew portulacas too. I don’t like them much. After two years trying different plants from seed, you end up having your favorites. Of course only you know the reason why.
