Strelitzia Reginae

 I love bird of paradise flowers. So when one day I noticed some seeds in the garden centre, I bought them. Then read how tricky the things are to get to grow. "Hard to germinate, easy to grow on". Hmm. Planted three seeds and gave the other half packet to Dad, who also loves the flowers. Most websites will tell you they take between 3 and 10 years to flower for the first time, so they are a patience plant! Hereīs my experience of mine.

Sown: May 17th 2001 and left in a conservatory. Humid, reasonably bright. Warm!

I checked a lot in the first month then totally forgot about the pot, which was by then at the back of some staging. I had a clear out of stuff in July and realised there was a quarter-inch thick shoot sticking out! That was quick for germination! Poked about and fished out the non-germinated seeds (one had rotted, the other was still solid) and then replanted the ok one. It subsequently germinated in August 2002 (!) and got given to Dad, who left it on a windowledge and it got forgotten. :-(

Come January 2002, mine was doing nicely: the tiny leaf at the bottom was the original shoot, and it grew another leaf every few weeks. But I began to see why it takes so long to flower!

I then kept it watered, fed it very occasionally and watched it grow leaf after leaf through 2002 and 2003. Dad finally got one to go, and put it in his greenhouse, but it doesnīt seem to be growing at the same rate as mine, perhaps because itīs cooler in winter. In January 2004 it occurred to me to take another photo (left). Much bigger now! Started to wonder if it was possible to get a flower earlier rather than later. However, the summer had its own surprises, and not terribly nice either.

I found out the hard way that Strelitzia suffer badly from Red Spider Mite. Grumble. I lost leaf after leaf to yellowing, crispy edges and the horrible little nasties. Tried organic methods, but they all failed. In desperation I sprayed it with a pesticide for vegetables (in the hope it was less bad for plants if it could be put on edibles) and that finally stopped the infestation, but by then it was looking very sad indeed. I watered it, fed it and put it at the back of the conservatory and left it to recuperate, wondering how much of a setback it had received.

Again forgetting about it was the key. On the day before my wedding in October 2004, I thought Iīd better clear up the conservatory in case it was needed for photos, and the Strelitzia surprised me again. There were two shoots sticking out of the crown, not one! So I gave my bridesmaids a heart attack as I bounced about grinning, thinking it had split.

It hadnīt. It was growing a leaf out of the centre, and the other was the long-awaited flower spike. What a wedding present!

Here I am in the first week of January 2005, and the spike is now a metre tall and starting to widen and turn orangey in colour. I think at some point in the next month it will start to bend into the beak, and then I look forward to it opening! Watch out for the pictures...

I have a hope that it may open by Christmas, but itīs more likely to be mid-January at the rate itīs growing. Either way, itīs less than 4 years, which is pretty good!

And yet another set of petals! Now the crest is really looking spectacular. And I think thereīs a fourth set inside, too.

The fourth set of petals has been up for a couple of days. The first set has gone over now, leaving the other three still bright. Itīs certainly put on a lovely display - I have no idea when it will flower again, but at least I have my photos!

February 12th

And hereīs the second lot of petals - and a second style/stigma too. I hand-pollinated the first one so Iīm hoping for seeds (though this may only work if pollinating another plant - but thereīs only one way to find out!).

Oh help thereīs a fifth set just peeking through the beak... itīs not over yet!

April 2nd

Except it was over - it was just the last petal. Still, the seed pod is now swelling rather nicely...

April 17th

Off we go again. Sowed two Strelitzia Reginae `Mandelaīs Goldī and two S. R. `Junceaī in pots in the heated propagator, after first scratching the capsule so water can penetrate easier.

May 15th
Peeked in pots, risking finger blight. One juncea seed seems to have vanished totally, one Mandelaīs gold has germinated! Repotted in its own pot. Other two seeds were looking ok and not soggy (I really want to know where the other juncea is - probably hiding in the compost).

July 2005
There is something odd happening in the pot. Not one but two slightly crinkly leaves grew very quickly out of the centre last month, and now Iīve yet another mangled pair coming, at rather odd angles too.  I have a suspicion that it means the plant really is trying to split this time...  The seed pod is still reddening, and so far hasnīt shown any inclination to split open. The Mandelaīs Gold seed put up a tiny leaf and then stopped. Just sits there, so Iīm hoping this means itīs getting a decent root system set up now itīs got means of photosynthesis. Things are rather better than last year as Iīve got predators keeping the red spider mites under control and so the leaves are all nice and green.

Strelitzia Reginae `Mandelaīs Goldī, sown April 17th 2005

The main plant mid-split, with seed pod near the roof!!

(The African violets, bougainvillea and Phalaenopsis orchid all rather like it in the conservatory, too.)

August 2005
Sadly the seedling shown above is no more - something had been eating away at the stem and it just came off. Probably sciarid larvae. Grr.

To compensate slightly, the splitting of the main plant continues, though the first leaves out are a bit crinkly! And the seed pod has ripened and split, giving me six incredibly shiny seeds with orange tufts :-)

Planted three immediately (and will cover with cling film to stop any sciarids getting in.) Three going to whoever yells first on Allotments 4 all or emails me using the addy on the front page of this site!

End August 2005
Peekaboo. New flower coming! Huzzah! This time I spotted it early on, and itīs on the other side of the plant to the last one, or rather on the other plant if this split ever sorts itself out.

Home after a weekend away and find Iīve got a bloom out already - so it will be at its best for Christmas. Wonderful! Almost unbelieveable that the last flower only died back in  March.

July  2006
The main plant is now growing three leaves a time, and large ones at that. I didnīt expect a three-way split, as the third heart started as just one leaf! The first attack of red spider mite in late May seems to have been beaten back (mostly due to the predators again, which I ordered as soon as I saw the mites) and the seed pods from the flower above are ripening rapidly. I expect theyīll crack in the next month. I managed to pollinate three of the blue flowers this time and each then grows a cylindrical pod within the `beakī.

Meanwhile, one of the last batch to be sown has germinated, and thereīs no sign this year of sciarid so Iīm hoping it establishes and doesnīt get nibbled off! (Would also be nice if the other three seeds grow, but 1/4 seems to be about the right odds for strelitzia!)

August 2006
The seedling mentioned above fried in the incredible heat of July, only to have a second one pop up a week or two later and start to fight the sciarid, which has also appeared. This one is being coddled and the temperatures watched very carefully! It is growing very quickly, and is already unfurling a leaf. Bit different to the Mandelaīs Gold last year; it must have stopped because of the sciarid grubs. Pah. Have discovered theyīre immune to both Provado and bifenthrin so have no idea how to kill the things now! Oh for the EU to reinstate malathion! That killed them... Iīm only non-organic where the ornamental tropicals are concerned, and even then, thereīs not much available now to kill stuff.
The better news is that Iīve got TWO flower spikes just appearing! So the split was successful. Happy.
The home-grown seeds ripened and were extracted, and though Iīm not convinced that theyīll grow, Iīm going to sow a potful to see.

September 2006
Should have looked closer. Thereīs a THIRD flower bud still within one of the leaf stems. Oh, my.

The two easy to spot spikes                    and a hidden one ( I hope).                The new one - shooting rapidly upwards

December 14th 2006
And the first spikeīs first flower is out. The three of them donīt look too far apart in timings, so I reckon thereīs likely to be a second by Christmas Day. Just in time for all the visitors! Of the small ones, Iīve got the first one with two leaves, the second oneīs just growing its second and the third oneīs struggling a bit as it got hit by the autumn aphid invasion. Should pick up though, especially when it gets to the second leaf. Luckily my notes at the top of this page do help - especially the part where I commented that they take forever to grow new leaves! Dropped the temperature in the conservatory by a couple of degrees so they last longer. Though with three spikes, with luck theyīll last a few months.

My original plant is now about 1.3m across and the same high. Good job Iīve plenty of room!

strelitzia171206_2

Flower spikes: the second oneīs bulging orange at the top so I donīt think it will be long before the petals pop out.

strelbabies171206

Kindergarten! The new ones, at least one of which was from collected seed as I only had a couple of bought ones left. Five years and counting...

Saturday December 23rd
Second spike out, second flower of first spike out. Turned the plant around so theyīre easier to see, and realised how big it now is. Two more views, with the big digicam. Clicking on the pics will give you a larger one. All three flower heads visible on the right one.

And more pics, now that all three are now out and looking lovely. Iīm only pollinating two of the flowers, to see if it does actually make them last longer if they arenīt. And I can cross-pollinate the two, though given itīs genetically the same plant, that shouldnīt make any difference.

4th September 2007
What a summer my poor indoor plants have had. They were barricaded in the conservatory by all the contents of the shed, which had to be transferred after a tree destroyed the shed in January. I thought it would only be for a few weeks, not expecting that the replacement shed wouldnīt be complete until August. As a result, a lot of plants died through lack of water, both because they werenīt reachable (Iīd pushed overwintering pots under benches) and because I was too ill with hyperemesis to lift a watering can for some months.
Somehow the strelitzia survived, though it did lose about half a dozen outer leaves. The two larger babies also survived, and I think the smallest one only succumbed because it was also being badly attacked by aphids. When I could get to them again at the end of August, I started watering them with as much as theyīd take, trying to get the soil to absorb some moisture (it was bone dry). A lone leaf had started to grow on the main plant, which was encouraging.
Today I realised just how tough these things are. As if I didnīt know from 2004. Another shoot has appeared - and itīs pale green one not dark, which is characteristic of a bud. How on earth can it be flowering when itīs been watered perhaps three times since March, for goodnessī sake? Well, in its native South Africa, they are often growing in dry conditions for months until the rainy season. Something for which I am currently very grateful! I donīt think Iīll have it flowering by Christmas this year, but Iīll settle for anything I can get. Including survival. As it was, I lost the aspidistra, both the stephanotis, and the streptocarpus; the two phalaenopsis orchids really donīt look very well but are hanging on.

I shall look forward to it cheering me, in the dark months when I am struggling with the exhaustion that is inevitable with a new baby, and canīt do much else!

Whatīs left of the main plant - three very separate crowns of four leaves each. Babies are the little plants to either side.

strelbud050907tn

And the surprise bud, despite everything.

11th September 2007
Oh brother. Second bud has appeared on the same crown as is growing a new leaf. Donīt believe it!

 

23rd January, 2008
We are almost at flowering point. Took a couple of shots just because thereīs a colour change along the top of the flower when itīs about to open; havenīt commented on this before.

 

24th January, 2008
And the petals start to appear... pics also of the young plants. Hopefully well on the way to getting flowers of their own in a couple or so years.

25th January, 2008
And weīre open.

6th February 2008
This is why strelitzia are hard to kill once they get going. This is the main tap root, escaping the pot of the larger of the immature plants. These roots are huge and fleshy and must store a lot of water and energy. (I was going to use a pound coin for scale, then realised that not everyone reading this will have seen one - but I figure thereīs a fair chance everyone knows the size of an AA battery!) The smaller one also has an escaping root, but the drainage holes are smaller.
With the now-flowering plant, Iīve had to cut the old pots off several times in order to pot them on because of these roots, so donīt ever plant them in any expensive ceramic pots unless you particularly want to have to break them!
The second flower spike is now out, and the second flower is out on the first spike. That one, from soil level to top of the petals, is 124cm (4ī 1"). The plant is only in a 10" pot. Dilemma for this summer: do I repot it to a 12" pot or take a spade and split it into three separate plants which then wonīt flower for a couple of years? Probably the former, as I have the small plants for backup.
