  1. Hi Grant

    Thanks for visiting Plantbook.

    Millettia grandis is better suited for a larger space. Perhaps consider another species with a narrower growth form such as:
    – Cassinopsis ilicifolia (Lemon thorn)
    – Ptaeroxylon obliquum (Sneezewood)
    – Bersama lucens (Glossy white ash)

  2. Hi Glenice,

    Thank you for this website and your book. They are both great resources for indigenous gardeners.

    I am considering planting this tree in a 1 meter wide bed between my paved driveway and the boundary wall. I live in Thornhill Estate, Modderfontein, JHB. The wall is east facing so it will be in sun for most of the day until mid-afternoon. Do you think it will thrive in this position? We want the tree to shade the driveway and provide screening from the neighbours on the other side of the wall.

    Can you recommend any other trees for this job?

    Thanks

    Grant

  3. Hi Ernstine

    Thanks for visiting Plantbook.

    I’m not sure whether Millettia grandis will thrive in your area as it’s not naturally found in your area.

    Another indigenous alternative to the jacaranda is Bolusanthus speciosus (Tree wisteria).

    Check with your local nursery for availability of these as that would be an indication of their suitability for your region.

  4. Could I grow this tree in Betty’s Bay, that is assuming I could buy a specimen. I so loved the jacaranda growing up in Zimbabwe and was told about this tree as a possible comparison.

  5. Hi Paul

    Thanks for visiting Plantbook.

    You’re clearly a serious and patient gardener. It’s interesting to hear about our South African plants being cultivated in other locations – definitely not a challenge for the faint-hearted as plants may sometimes require a little more care in order to flourish!

    Thanks for your observations and I hope your Millettia grandis provides you with a splendid show after all your efforts.

  6. My one seed grown plant is now 35-40 years old (NE NSW warm, supposed to be wet, subtropics) and has yet to flower probably in part, at least, if not totally, by not being in full sun for most of that time. When initially planted it was full sun as the program was converting a dairy farm to jungle botanical garden. Over this time it went to dappled light and for years shade alot of the year 24/7. Yet the tree remained healthy if not robust. Currently about 4-5m. Recently I have taken some ‘drastic’ measures of serious lopping and outright killing to thin the canopy for more light on selected specimens. This includes the Millettia that now has more light but still not even one hour a day of full sun. it might in winter with the low sun and deciduous Lecythis pisonis leafless. 🙂 Just wanted to let it be known M. grandis here for me tolerates low-medium light, but what’s the point i no flowers, eh? Then again maybe nutrition is holding the flowers back: a phenomena encountered not infrequently before e.g. Dovyalis rhamnoides (took 24 years and Rustica Plus). The parent plant @ Sydney was in full sun, beautiful lollipop structure, and profuse flowering.

  7. Hi Paul

    Thanks for your comment.

    Yes, sadly, some nursery staff don’t have all the answers.

  8. Hi Anelia

    Thanks for visiting Plantbook.

    Millettia grandis needs to have at least 6 hours of direct sunlight. So, firstly check if that is the case. Move it if possible and see if it recovers.

  9. Hi I just bought a tree like this, when I bought it I’ve asked If I can have it inside the house and they said yes, now the leaves is going yellow and falling off, I don’t know if I’ve watered it to much maybe 500ml a day is to much

    Please advise

    Kind regards
