Furcraea longaeva¹ starts to flower
at Earlscliffe
April/May/June 2009
The Furcraea longaeva is a succulent related to Agave
and is known in its native Mexico for having a very tall flowering
inflorescence – upwards of 12 metres (40 feet)!
We have a number of Furcraea at Earlscliffe. The tallest
(and oldest) is about two metres high and has been planted at Earlscliffe for
about fifteen years.
In April 2009 it started to flower.
It has flowered in many places outside of its native country. A web
search shows that it flowered at the
Abbey Gardens on Tresco,
Isles of Scilly in 2001, at
RHS
Wisley, Surrey, England in 2004, and in
North Devon, SW
England in 2006.¹ However, we are
uncertain it has flowered so far north (53.3º) before!
We will continue to photograph it regularly to show how tall the
flowering spike grows. Of course, it won't reach 12 metres! However, at its
fastest it was growing at a rate of over 12cm (over 4.5 inches) per day!
It now stands at around 6.36 metres tall (nearly 21 feet) and the
growth has slowed right down to only 1.43cm (just over half an inch) daily.
Footnote
¹. The Furcraea was planted around
1994 by David Robinson who identified it as F. longaeva. However, there
has been a lot of debate about whether the plants sold as F. longaeva are
in fact F. parmentieri (see the
RHS Advisory Panel on Nomenclature & Taxonomy – 21 January 2008).
The Furcraea in flower
Picture taken 13th April 2009. The plant itself is over two metres tall
and the flower is about 30cm. |
 19th
April 2009. The flowering spike is about 90cm |
 22nd
April 2009. The flowering spike is around 1.3m |
 25th
April 2009. Spike is now 1.7m |
 27th
April 2009. Now the spike is around 2m tall, doubling the size of the whole
plant. |
 29th
April 2009. Another 30cm added. The spike is now 2.3m and the whole plant is
4.3m tall |
 2nd May
2009. The plant growth seems to have slowed down with the spike at around
2.4m tall. It is now opening up more. |
 9th May
2009. The plant has grown further and is starting to outwards. The spike is
around 3m tall with the overall plant now standing 5m high. |
 12th
May 2009. The spike is now around 3.25m tall, making the whole plant 5.25m.
The pole I have been using to measure the spike is about 4 metres long, so I
haven't much left to hold on to! |
 22nd
May 2009. The spike has grown again and is now around 3.7m tall, making the
whole plant 5.7m. I have now attached a length of wood to the original pole
to help measure the plant! |
 30th
May 2009. A bit more growth. Now the spike is 4m tall, making the plant 6m
in total. Think I need a longer pole! |
 9th
June 2009. A little more growth. The spike is now 4.26m tall, making the
total height of the plant 6.26m. The growth has finally slowed down and is
only about an inch a day (2.6cm) (thank goodness as my measuring 'stick' is
almost at its limit). |
 9th
June 2009 continued. The drooping inflorescences are where the main
activity is happening. |
 9th
June 2009 continued. The individual flowers are starting to appear and the
whole plant is starting to take on a more pleasant shape. |
 16th
June 2009. Slowed right own now (thank goodness as I had to get rid of my
pole and now have three long bamboos taped together to measure it). The
spike is 4.36m with the total plant being 6.36m. It is now at about 1/2 and
inch a day (1.43cm). |
 16th
June continued. The plant has a flourish of echium candicans at its
base. |
 16th
June continued. The flowers are starting to look spectacular... |
 16th
June continued...with many more flowers to come. |
