71025thumbJust like warm season vegetable plants in the vegetable garden, flowering warm season annuals get replaced this time of year. Although the weather is still warm, cool season annuals should be planted now so they can disperse roots before the weather gets too much cooler. Except for a few short term annuals and perennials, most should perform until the weather gets warm next spring.

Pansy, viola, Iceland poppy, sweet William, calendula, stock and the various primroses should get down to the business of blooming rather efficiently, and hopefully compensate for the removal of deteriorating warm season annuals. Ornamental cabbage and kale, as well as cyclamen, can be a bit later because they are a bit more sensitive to warmth, but not slowed much by cool weather.

Nasturtium and alyssum can work as either or both warm and cool season annuals. Both are annuals, so individual plants do not last more than a few months. In hot spots, they may perform well in winter, but then get roasted in summer. In cold spots, they may do exactly the opposite. In the right situations, they self sow and bloom all year. Tired old plants should be groomed out if unsightly.

Chrysanthemums are the most prominent of seasonal color for autumn, and come in all sorts of colors that are ideal for an autumn palette. They are actually perennials that are grown as annuals. Unfortunately, they are usually grown as very short term annuals, that are allowed to bloom only once, and then replaced with something more wintry, like cyclamen or ornamental cabbage or kale.

Like cool season vegetable plants, most flowering cool season annuals should be planted as small plants in cell packs. Chrysanthemum, as well as cyclamen and ornamental cabbage and kale that get planted afterward, are the exceptions that should be planted as four inch potted plants, but they are expensive anyway. Primroses can be planted from either cell packs or four inch pots. (Primroses can cause a serious skin allergy, just from contact.) Nasturtium and alyssum should be grown from seed sown early.

    1. I don’t want to brag . . . but I do all the time. Although, I find that there are many things that we can not grow well. For example, bulbs that need a chill in winter are like annuals for us. They bloom once and not much the following year.

  1. G’day Tony, interesting to read about your transitioning time to your cooler weather. I also have nasturtium that drop their seeds every year and are feral and take over in various areas, but I love them…

    1. Oh yes, I mentioned nasturtiums so many times, I can not remember what I said about them in each article. I enjoy them that much. I know people make fun of them, but I do not care. I will actually be planting more pretty soon. Instead of planting feral seed, I might try a variety again.

      1. Renee’s Garden has more varieties than I can try, and I do not want to get rid of the feral ones to make room for the varieties. I do so sometimes, just because I want to try them. The funny thing is that, although white is my favorite color, I do not like the ‘white’ nasturtiums. They just are not white enough. Besides, they really should be brightly colored.
