A flower that is worth mentioning is the new guinea impatiens. I have worked with these flowering plants over the years and have seen the beauty and flavour new guinea impatiens brings. These garden beauties can really give that POP when planted in masses in assorted colours in the garden area, used as an undergrowth around coconut palms and other trees, in containers, low hanging baskets and so on.

Caution should be taken however because if the soil is allowed to dry out your Impatiens will wilt but a good drink of water or soaking will cause your plant to bounce back, therefore, it is good to ensure that the soil is moderately moist at all times.

Plants which are leggy meaning they have lost most or all of its leaves and plants that are overgrown at this point should be trimmed.  The removal of brown and discoloured leaves, old flowers and other plant parts will keep your impatiens healthy and attractive. Remove these plant parts by pinching with your fingers this procedure will encourage new bloom causing your plant to become fuller.

    I want to decorate my garden with flowers and I didn’t have any idea of what to choose. It’s the first time I hear about the New Guinea Impatiens. Those flowers are beautiful! The good thing about them is that they can be grown in both full and partial sunlight. Anyway, I just would like to know if the New Guinea Impatient exist in other colors? Or they are available only in purple?

    Thank you very much for this useful post!

  5. With its high temperatures, and dryness, generally South Africa , would not seem to be a suitable place, to grow these plants.Do you think that with careful preparation and watchfulness, these could be overcome?

    I have visited several ornamental gardens, and have been delighted, by the mass displays, of these ground hugging type plants.

    To get the full effect, of the mass displays, of these type of flowers,one needs all the varieties one can get,such as the 6 varieties mentioned.

    One needs to to work carefully,  and take all the precautions mentioned, in preparing and keeping your soil right, for these plants 

    • Hello Robert so happy to meet you. They are many keys to meeting a plants requirements, once these requirements are meet you will have good success. Yes with good preparation you will be well on your way. Thanks so much for sharing and wishing you all the best of success. 

  6. What I liked about your review on these flowers is you gave practical suggestions on where to place and / or plant these flowers for best effect.

    One of the crucial factors to having a successful garden of flowers and plants is to be able to know when they all need water.  Not all plants need water everyday and so it is imperative that your condition of keeping the flowers moist at all times, but not to over-water them, is a great tip.  I know I struggle to know how much water to give an orchid, for instance.  These flowers are quite fickle and one needs to know just how much or little to give them.

    The variety of colours gives a great array bringing brightness and happiness to the garden.  Thank you for your extensive review of this flower, I’ve learnt a lot from reading it and am now well informed.


    • Hello so happy to hear from you, all it takes is knowing how just like any other field of work and you will be sure of success. I am so happy that I could help and thanks for your kind words. Wishing you all the best of success.
