Agave angustifolia 'Marginata'
/ Variegated Caribbean Agave
for the Northeast Florida Landscape
( Agave angustifolia 'Marginata' )
Variegated Caribbean Agave angustifolia 'Marginata' Plant Origins:
Native to Mexico and Central america, but naturalized in other arid areas of
the world where it is cultivated for its use in the making of the alchoholic drink known as Mezcal.
They can be propagated from pups or offsets near the base of the plant and from bulbils or seed.
The variegated form 'Marginata' , as I'm sure you could tell from the
name, has a soft almost pastel or pale sage green leaf that is beautifully edged with a creamy
white variegation on the leaf edges.
Although commonly called a thin leaf century plant, the life cycle from seed to
bloom is said to take a very long time in dry arid climates. Here in our warm moist semitropical climate
zone in Northeast Florida , they can bloom much sooner in as little as 6-10 years. When the bloom stalk
rises high above the foliage at 8-10 feet it is quite the spectacular show. What I find
interesting about the flowering stalk of Agave angustifolia is the bulbils that form on the
flower stalk as it blooms and forms seeds. These bulbils will fall to the ground and given the right conditions
a new plant will grow.
Sun / Shade Exposure for Variegated Caribbean Agave / Agave angustifolia
- Caribbean Agave plants can be planted in a full sun or a partially
shaded location in the Northeast Florida | Jacksonville | St. Augustine area landscape.
Foliage of Agave angustifolia 'Marginata' :
Strongly upright form with stiff straight variegated foliage. One of my
favorite Agave selections, I'm a sucker for some pin striping on a plant, I love variegated foliage. For some
reason, Agave attenuata reminds me of a big sea urchin, I know, enough with the imagination! maybe its the
overall rounded symmetrical look of the plant. Anyway....
Caribbean Agave foliage reaches 2-4 ft high and wide and has a pretty sharp tip on
each of those thin leaves that can be cut off to make it a bit more child/ pet friendly than the garden
porcupine it resembles. I know, I said I would quit with the imagination. Apparently I lied. :)
Soil Preference / Salt tolerance of Agave Plants:
Century plants will prefer extremely well draining soils that are comprised mostly
of sand. If you have clay soils or nice black dirt that grabs and holds water after rains here in Northeast
Florida it would be a good idea to relegate your Agave plantings to raised bed areas and decorative
Agave angustifolia 'Marginata' plants are salt tolerant and
make a great plant selection for coastal plantings.
Agave are extremely drought tolerant as their foliage is a water storage unit for
the plant allowing it to survive periods of extreme drought unharmed.
Allow your agave plants to go unwatered during the winter months to
strengthen their defense against a hard freeze.
Care of Agave angustifolia 'Marginata' in the Northeast Florida /
Jacksonville and St. Augustine Landscape:
- Plant into well drained soil that does not stay moist or wet long after
rains. In frequently moist or water logged soils consider building up a of sandy soil at least 6 inches above
grade and two to three feet wide to plant your Agave in.
- Agave make great container plantings as containers tend to dry out quickly
even with daily rains. Consider planting in a decorative container with drain holes that can be planted
into the ground with a minimum of one third to one half of the pot left above the existing soil level.
- Water once or twice a week during the establishment period after planting in the
garden from an S & J Nursery container.
- Mulch heavily to reduce weed growth under the foliage. Consider using a pre
emergent herbicide like Preen or placing a .5 - 1 inch layer of newspaper under the mulch around the plant
after installing your new Agave to inhibit the growth of weeds that may be hard to reach under the Agave
-Fertilize each spring with a well balanced plant food like Osmocote.
