One of the best of the Yucca group - not as untidy as
ages as some other Y. filamentosa group. It forms a
stunning architectural shrub, which is best suited to the
sunniest spot you can find. It will grow in virtually any
soil - other than heavy clay, and its main requirement is
plenty of drainage and not to be too wet at root level
during the winter months.
Bright golden margins to the mid green dagger-like leaves. The leaves
- as with all Yuccas - are very pointed and sharp at the ends. It is of
course fully evergreen and hardy if planted in a dry situation.
individual leaves can grow to around 60cm long - 2 ft. Not clump forming
as with other Yuccas, but more of a branched shrub, with rosettes of
foliage sprouting from main stem. Overall this Yucca can grow to 1.5m
with a similar spread. The upright flower spikes are well above
the foliage and can rise up to 2.4 meters - a spectacular sight
in the late summer or even through to winter. As can be seen in
the image the flowers are white but with pink-purple buds.
Where and How to Grow Yucca gloriosa
Yucca gloriosa is suited to growing in patio pot, but be aware of the
spiky leaves - especially with children to think about. The large head
can make for a top heavy plant in a container, do either use a large
container or have some way to make it stable so as not to fall over and
damage anything. This Spanish Dagger is best planted in full sun, but
also tolerates dappled shade - even for growing below large deciduous
trees such as Oaks!
If growing on a busy patio - or near a walkway, the 'dagger' sharp
points of the leaves can be clipped with shears. Sounds horrific, but
may be necessary for safety when mature.
Spanish Dagger is the type of plant that needs its own 'space' where
it can show off its wares - foliage, flowers and general 'attitude'! It
is not one to be mingled or surrounded by other shrubs. As it is
reasonable bare at ground level - in the early stages - consider
planting some low growing complimentary plants. Some of the large
coloured foliage Sedums spring to mind, but so do the French Butterfly
Lavenders. It is the type of plant that needs thinking about to show it
It will eventually become multi-stemmed - sometimes from the base, or
branching out from main trunk. It often suckers from the roots. Bear
this in mind for long term planting. It really does need space for
development, and will repay you handsomely.
It is very tolerant of salt water spray, so ideal for planting as a
Propagation of Yucca gloriosa
This yucca is easily propagated by 'root cuttings' in mid winter,
but also can be propagated from the sprouting 'toes' from the roots.
Allow them to grow for a season, and then they can be cut back to the
root - with roots attached in early spring or late autumn.
Pests and Problems of Yucca
The main problem arises out of planting it in the wrong place! Yucca
does not easily transplant - though they can be.
Other than greenfly on the flowers sometimes, they have no real
problems to worry about.
Leaf spot fungus might be troublesome. in which case keep a lookout
for the browning spots and treat as soon as possible with general
