Flowers are categorized as Annuals, Biennials, Perennials or Tropicals.
Flowers bring joy to people and can add a wide range of colours into the landscape.
Although, many people are switching from using annuals over to perennials, annuals still have the advantage of longer bloom times in most cases. They will need to be planted every year, once all frost has passed, or if planted earlier, must be protected from frost. They will require regular watering throughout the season.
Biennials need 2 years to bloom, then set seed and die.
Perennials, once planted come up every year. They will save on the cost of planting annuals every year, but they will still need a fair amount of work. In some cases perennials will be low maintenance, eg. Hostas, but most will need regular maintenance. In order to keep them looking their best and healthiest, regular watering is required to get them established and during dry periods and also deadheading , pruning , fertilizing and weeding. Every so many years, you may need to divide overgrown plants and transplant them. There are times when perennials fail to come back in spring. This may be because severity of winter weather, too much winter wet, poor drainage, wrong location for specific plant or rabbits. For the most part, perennials are a good investment and provide us with endless possibilities. There are always new varieties being introduced – hard to keep up with – but very interesting to work with. Some of the newer varieties have longer bloom times and better characteristics. Usually perennials have more seasonal bloom times compared to annuals.
Tropical flowers come from warmer zones and are not hardy outside in our winters. Some are well known for setting out on our patios, porches and around pools and then, taken inside where they will receive plenty of sun for the winter months. These include Hibiscus, Oleander, Gardenias and many more. There are still many more that remain in the house year round for us to enjoy.
