Source for rosa banksiae lutescens?
Comments (6)To get the single yellow lutescens you're going to have to have one shipped in from elsewhere - if you can find a US source. If instead you are looking for the double yellow 'Lutea' there may be some around at a garden center somewhere in the area. You'll just have to make some more phone calls, maybe drive a ways to get it. The selection of roses now will not be nearly what it was in spring, and won't be back up again until peak season next year. If instead it being any version of R. banksiae is acceptable the double white form seems to have been the most prevalent at outlets here in later years. This was the original type first named R. banksiae and grown under that name. Later the true original wild species (with single white flowers and thorny canes) was recognized and became differentiated as R. banksiae var. normalis....See MoreBanksias Germinating well but then failing
Comments (7)Thanks for the feedback. I have had a good look on the web and have ordered some chelated iron (which also contains magnesium) and will give them a foliar spray. It seems that the worse thing to do is to be too kind to them and fertilise them. However they can suffer from iron and it seems magnesium deficiencies. Our soil is sandy and light so it is well drained. Have bought and planted some banksias from an English nursery that specialises in them (The Old Walled Garden in Kent) and they are surviving well, although one of them is looking a little yellow (*gulp*) so I'll go down the iron/magnesium and no added fertiliser route. If this works then I'll have a go at some more seeds. The mix that I started them off in was a mixture of sand, potting compost and perlite, roughly thirds. Thanks for the help and encouragement....See MoreGrowing Banksias in the UK - any advice please?
Comments (9)I have been growing Banksias in Vienne (near Lyon) France for 5 or 6 years now. I have some B coccinea seedlings myself, but this species has a reputation of being difficult. In WA, it grows in deep sand dunes near Albany, so use extremely well draining substrate. Secondly, my general experience with other banksia species (I have about 30 different, of which 5 have flowered) is that Banksias, do not like too much lime: I have very hard mains water here (equivalent of 280g of CaCO3 per cubic metre) and my early attempts at Banksia cultivation resulted in extreme chlorosis and death due to the pH rising. I have had much more success since I have taken steps to keep the pH down (I aim for pH 5). I even saved a chlorosed B blechnifolia by dunking it in a weak solution of Nitric Acid!! Even with these precautions some (not all) of my B coccinea seedlings are looking yellow, so I recently gave a dose of chelated iron. Thirdly all WA Banksias detest humidity, so do everything you can to reduce humidity in your greenhouse (fan, etc) and water sparingly especially in winter. Finally Banksias do not like phosphate, so do not use any fertilisers other than extremely low phosphate ones. Banksia canei grows in the Blue Mountains on the other side of Australia and is one of the toughest Banksias as far as cold and frost is concerned, so could be planted outside if you never get much lower than minus 5°C. I have also found that it is also more lime/pH tolerant than most banksias. More generally, as far as frost resistance goes, Australian climates are so different from Western European climates that only information gleaned from those who have tried growing Banksias in Europe is likely to be reliable. I have three 5 year old B canei and they are yet to flower. If you are seriously into growing Banksias and other Australian plants may I suggest you join the (UK) Australasian Plant Society? I would be please supply their address....See MoreLady Banksia Cold Hardiness
Comments (9)Sure hope you all are right! We had a week of bitter cold, one night was 3. Others were 12, 19 and in the 20's. What worries me is that I saw some splitting of canes and didnt see any kind of green on them. They are established bushes and line my driveway, just fabulous in the spring. But if they are alive at the roots.......and will return maybe all is not lost. I also worry about my glorious Crepuscules too. I have been pruning roses, starting with ones in pots. On most, I can see about an inch of green cane.......they are just nubs [and I have waited until I am sure the other cane is dead]. People in the north keep telling me they will come back......it is just hard to look at these pitiful things and believe they can become a bush with blooms again. I will say I am pleasantly surprised at this - the David Austin roses every one seem to have green canes.......esp. Mary Rose. Even a small potted Vanessa Bell. I have been amazed at the cold tolerance of these roses. Emily Bronte is the only one that looks like it will have to be taken back to 1-2". The wonderful Bucks of course are every one thriving. And a new one, while I am at it, I would recommend is a small landscape shrub called Coral Miracle - new last year. The cold didnt touch the canes on this little beauty. I like it in pots.....it came through like a champ, pretty color. Ya'll try one if you can find it for sale. I will just leave the Lady Banksias alone for now......going to really hurt to cut off that beautiful arching growth but if the roses are alive, as you all have given me hope for, they will grow fast and bloom next year. I may be able to find some one gallons with buds and plants those beside the big pruned roses just to see these gorgeous primrose yellow blooms.......thanks ya'll for the help.
