Snapdragon

80523They are short term annuals in spring or autumn. Where winters are cold, they may last from spring through autumn. Where summers are hot, they may last from autumn through spring. So what are snapdragon, Antirrhinum majus, here? They can be either or both, depending on where and when they get planted. For most of us, they are a cool season annuals that finish before summer.

Although they prefer to be in full sun, the warmth of such exposure is what limits their practicality through summer. They bloom a bit less in partial shade, but are more likely to last through summer if kept cool, particularly in an innately cool microclimate. Like many annuals, they want rich soil, and regular watering. Because they are susceptible to rust and mildew, foliage should be kept dry.

Snapdragon blooms in white and many cheery hues of yellow, orange, red and pink. Some of the older varieties, particularly those developed for the cut flower industry, can get very tall, and might almost reach low eaves! Modern garden varieties are shorter and fluffier. The biggest are less than four feet tall, and less than a foot and a half wide. Deteriorating flowers should be pruned away.

Annuals Come And Annuals Go

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.
