Tom starts with ... Are there distinct differences between young Davidsonia pruriens and D. jerseyana, in their leaves or trunk, for example, to be able to tell them apart before they're old enough to fruit? Here are a couple photos of the new addition in our garden, and I'd appreciate the advice of the folks in its native land to help me identify it. Thanks for your help.

BJ says... Is there any difference in the amount of hair or spikes they have, or is this variable between the individual plants? My metre tall tree is much hairier than this one, which looks positively leathery in comparrison. Jerseyana only takes 1-2 years? I've haerd the normal one takes so much longer than that to bear! Does anyone have info on how long the other variety might take, as I'm pretty sure that is what I have? I'll have to get the Jerseyana whatever the case. | About the Author Theposterformerlyknownas Brisbane 8th July 2010 4:12pm #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

Tom says... Thank you, all, for the thoughts and input ! I figured this would be the best place to go for good discussion. So far, the best source of data I’ve found outside this forum is the document at the link here: http://www.nativerainforestplum.com/uploads/2/4/5/6/2456114/davidsonia_revision.pdf. It includes an artist’s renderings of the two (and D. johnsonii as well) and highly detailed descriptions. But it’s still very hard to distinguish them. It’s further complicated in that there are so few of these rare plants on our side of the world that it’s practically impossible to make a comparison of two or more real ones. BJ, why would you have to get the Jerseyana in Brisbane? I’m sorry that I don’t know your zones so well yet and thought that Brisbane and Orlando are similar subtropical zones (occasional light frosts, rare hard freezes, dry winters, very rainy & hot summers). This may be a clue as to what’s growing now in our back yard. Tom | About the Author Tom Orlando, Florida 8th July 2010 9:43pm #UserID: 3912 Posts: 101 View All Tom's Edible Fruit Trees |

BJ says... Hi Tom, I guess I should have said that 'I really want a Jerseyana' for my yard, especially because of its early bearing nature. They also dont take up much space as mature trees, they are just poles with fruit, so I wouldnt mind having a few different varieties. I guess Brisbane and Orlando would be similar, though I dont ever recall seeing a frost in the mid north western suburbs here, let alone any freezes. We are quite close to the native area for the Jerseyana, but still warm enough to easily grow the warmer climate Davidsons. | About the Author Theposterformerlyknownas Brisbane 9th July 2010 12:45pm #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

Tom says... Southern QLD really must be paradise, BJ – I hope to see it one day. No memorable frosts, never a freeze, and I’ll bet no hurricanes either, eh? Good to know about the fruit-on-a-pole form which is what I was hoping for since we’ve put it only about 1.75 metres from the SE corner of the house to make sure a rogue low temp doesn’t harm it. Do both species take that form? HappyEarth, our plant is just about chest height now (good to know we use the same units of measure) which must make it about 2 to 2.5 years old now, and it’s never flowered. In fact the grower told me that his taller tree had never flowered either, but it may be that his having grown it in a crowded greenhouse (similar to what its rainforest habitat must be like) had some impact on that. So far from your notes it seems that ours has not so much hairy leaves as BJ’s (which is the n. QLD type, right?) That tends to make ours jerseyana. It’s taking the form of a pom-pom on a stick but hasn’t flowered though it’s taller than HappyEarth’s. That tends to make ours pruriens. It survived South Florida’s 100 year killer frost last year similar to how allybanana’s survived frost at the nursery in “eden”. That tends to make both ours jerseyana. Jury’s still out on our Florida davo, and your comments are greatly appreciated. | About the Author Tom Orlando, Florida 9th July 2010 10:10pm #UserID: 3912 Posts: 101 View All Tom's Edible Fruit Trees |

Rev says... I visited a bushfood garden in a place caled chillingham in the tweed valley (NSW) use google earth. They have both the Nth qld type and the NSW form. The North qld was very erect - like a palm or a pole, and thicker trunk with larger leaves. I believe the owner said they fruited at different times as well. The NSW was more bushy, shorter, smaller leaves. this was accentuated by being in a more open spot. South east qld has no freezes though they do get periodic frosts - last big one was about this time in 2007. It hit the whole east coast even up here in North qld there wer -8C records on the western edge of the atherton tablelands. I recall seeing burned foliage on rainforest near byron and narrandera. It looked like autumn colours! SE qld also gets bad droughts. so youve picked a good spot to try things from! | About the Author Rev North qld 10th July 2010 6:39am #UserID: 1806 Posts: 359 View All Rev 's Edible Fruit Trees |

Tom says... You're the best, Rev! I think ours must be from the North. All you Aussie's are such fine folks. Thank you immensely for the personal time you gave to my question and for all the info. I'm much obliged to you and to all those who suggested and also asked. If any of you are interested in acquiring seeds from my side of the planet which may be hard to come by down there, I'd be happy to search them out them, cleanse them, and send them. (Whether they can get through AQIS or not in the post, I'll leave up to you.) Just let me know what you'd like. I know the Tweed Valley now, Rev. I've been google-earthing Australia intensely lately as I've become enthralled with your beautiful country. Lately I've been thinking about a line from an Indigo Girls song: "When God made me born a Yankee, He was teasin'." I'm sure He meant to place me in Australia; but I'll just have to settle for growing a few Davidson Plums, Tree Ferns, Finger Limes, an Illawarra Flame Tree, and Jacarandas in an attempt to mimic Paradise.

BJ says... My father has a very large puriens. well over 20ft, probably closer to 30. When I first saw it I didn't recognize it, as it was just a great pole with a few forked branches near the top. It crops 3 or so times a year in the warmer months with largish plums, and hundreds of them. But his are on the edge of a rainforest patch that was planted by regen/permaculturists who lived there a long time before he moved in, and estimates put the tree at near 30 years old... But what a tree! | About the Author Theposterformerlyknownas Brisbane 10th July 2010 10:07am #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

Rev says... some of my brightest memories of Northern NSW is the combination flowering of street trees in country towns in spring of- Jacaranda - blue (from brasil but who cares) Flame tree - red/orange and Silky oak (Grevillea robusta) - bright yellow i also think the lacebark Kurrajong (Brachychiton discolor) is greatly underutilised - it has dusky pink flowers i added my own addition by importing raising and selling a number of silk floss tree (Chorisia speciosa) from similar climate in argentina its so cheerful after a frosty winter! goo luck with the D plum! | About the Author Rev North qld 10th July 2010 4:44pm #UserID: 1806 Posts: 359 View All Rev 's Edible Fruit Trees |

Tom says... Well, it may be off-subject now of the D Plum, but your memorable images of NSW, Rev, are actually taking shape now here in Orlando. I hope we can match your memories one day. Our front yard has three Jacs (two 3m tall trees installed last year at the street and a big one center yard the year before), and the Flame Tree (about head height now and still in a pot with Miracle Grow soil to boost it) will be set directly across the drive from the big Jac so that their branches will mingle a bit one day. We used Yellow Tabebuias (Tabebuia chrysantha) for the bright yellow and added Pink Tabebuias (Tabebuia heterophylla) for the pink. Our excellent neighbor let us set the yellows across the street on her curb to arch the street and touch the Jacs spreading from our curb. All these bloom in concert, with the Pink Tabs lasting about 8 weeks from FEB through APR. (By the way, we're overloaded with Pink Tab seeds just now if you want any and are allowed for me to mail them in.) Just after them, Chaste Trees (Vitex agnus-castus) set opposite in our yards bloom for a few weeks into JUN. Our Silk Floss is set closer to the front door of the house and gets the stage all to itself then later in the year (OCT blooming). We also put a big one in our neighbor's center yard to balance the other side. And, just this week, two of the Lacebark Kurrajong seeds I planted a few weeks ago sprouted. There's a place reserved for one (if I can tend them into a good size) between the Flame Tree and a Yellow Tab in our back yard. The inspirations for this were pictures I've seen of Australian towns (and the beautiful landscaping at Walt Disney World not too far from our home in downtown). Almost forgot - three short, stout Quince trees set on the perimeter throw in a little light pink at the same time, but they're demur compared to all the other bright colours of the taller trees. On the opposite side, three short Crepe Myrtles (dark mellon coloured) put a little colour up high in the summer when the Agapanthus are blooming underneath. It's very nearly n. NSW or s. QLD here just separated by a long distance, half a seasonal year, and fourteen hours. | About the Author Tom Orlando, Florida 10th July 2010 10:14pm #UserID: 3912 Posts: 101 View All Tom's Edible Fruit Trees |

PouteriaLover says... Hi - I am wondering if these growths on my Davidsons plum are flowers forming (the one that my hand is holding )and if so - is this type of flower is diagnostic for a pruriens species? I purchased the plant as a pruriens - but want to make certain of that ID....? I have a jerseyana also - but it's still a baby - although it seems different to me ie: more prickly and "e;shrubby"e; - whereas this plant is tall and smoother, more droopy leaves... Many thanks... (pictures taken at different times - just to show the overall plant growth)
