What’s Wrong With This Landscape: The Answer

Southwest garden

Welcome to the second edition of “AZ Plant Lady Drive By: What’s Wrong With My Landscape”.

Where you able to figure out what was wrong with the landscape, below?

wrong with the landscape

I got some great answers and they were all right, BUT only one person noticed one problem that others hadn’t.

Here are a few of the answers I received on Facebook:

“Huge needle sharp plants next to a walkway.”

“The century plants (agave) need more sun.”

“Agaves planted too close to walkway, tree planted too close to house, poor pruning of Bush between houses. Looks like the Bush was trimmed with a chain saw. The mixture of desert and green landscaping is a bit much.”

These were great comments and were correct, but there was one other problem that only one of my readers found. Here is her comment:

“Those agaves are going to cause a lot of trouble.  They will multiply and take over the tiny area they are planted in.”

1. First of all, you should not plant prickly agave near areas where people walk – like along the driveway or an entryway.  Getting pricked by an agave hurts – I have had this happen countless times to me while in the field and once or twice at home.

2. The choice of agave in this landscape is a poor one. The agave in this landscape are called Agave americana and are perhaps the most commonly found agave that I see in landscapes.

While these agave are attractive, they do have a characteristic that makes them high-maintenance – they produce lots of baby agave (also called volunteers or pups).

wrong with the landscape

These volunteers are prolific and take a lot of time to cut them out.  The agave group, above, started out as one Agave americana that then reproduced. The majority of agave pups were removed, but six still remain.

This homeowner has kept up with removing most of the volunteers – but it is hard work.

prickly agave

Removing the volunteers means getting up close to these prickly agave and it isn’t easy to remove them. You have to get your shovel down into the soil a few inches to cut off the volunteer from the parent plant.

Homeowners usually allow the volunteers to grow, which over time, creates a somewhat unattractive mass of agave.  OR they remove them and plant them elsewhere in their landscape, which just increases the problem because those replanted agave babies will start making their own babies.

Agave americana

Now, I think Agave americana are beautiful (as does the little hummingbird perched on this one).   But, I wouldn’t plant one in my garden.

So, is there a solution for homeowners like me who love how agave look, but don’t want lots of babies to take care of?

Yes!

There are many different species of agave that don’t produce volunteers, or not too many.

Here are a few of my favorites that will make a good substitution for Agave americana:

Agave bovicornuta

Cow’s Horn Agave (Agave bovicornuta) is a beautiful agave and does not produce any volunteers.

They will grow approximately 4 feet wide and tall.  Plant in an area that receives filtered sun or afternoon shade.  This agave is hardy to zone 9.

'Octopus Agave'

You can see why this agave is called ‘Octopus Agave’ (Agave vilmorniana).  It does mimic that tentacles of an octopus.

This agave will not produce volunteers either.  It does best in filtered shade or in an area that will receive afternoon shade.  Hardy to zone 9.

Weber's Agave (Agave weberi)

Weber’s Agave (Agave weberi) is my favorite large agave.  I am using several in a new landscape area that I designed alongside a golf course.

This agave grow 5 feet tall and 6 – 10 feet wide.  I does great in full sun.  It does produce the occasional volunteer, but not many.  Hardy to zone 7.

I hope you have enjoyed this edition of “AZ Plant Lady Drive By”.  Thank you all for your comments.  I’ll keep my eyes and camera ready for other “landscape no-no’s” to show you.

My goal is not to poke fun at those homeowners who have made mistakes.  I want to help you to avoid making the same mistakes in your own landscape.

Flowering Once In A Lifetime….

Agave, Arizona garden, AZ Plant Lady
flowering stalk of an agave

Imagine a plant that lives for years, never flowering, and then towards the end of it’s life, expends all of it’s energy to produce flowers on a giant stem and then dies….

Agave Stalks Begin Growth

The story begins with an agave starting to grow it’s flowering stalk, or inflourescence.  The growth is incredibly fast, growing up to 1 ft. each day.  Depending on the species, the flowering stalk can reach heights up to 40 ft. 

almost full grown tall flowering stalk of the agave

Agave murpheyi sending up it’s flower stalk.  *I took the picture, above, at a client’s house and she referred to the flowering stalk as an ‘asparagus stalk’ because that is what it looks like.

When most people think of Agave, they think of the Century Plant, (Agave americana), and believe that it will flower once it reaches 100 years old.  This is actually a myth.  Although the timeline can vary, Agave americana does not live that long and flower much sooner.  There are over 250 agave species and most flower towards the end of their life and then die.

Actually, the length of time an agave lives is largely dependent on the species.  In my experience in the managed landscapes, most agave live approximately 5 – 15 years, once planted from a 5-gallon container.

Different Types of Flowering Agave Stalks

I am not completely sure what species this particular agave was. Note the ‘pup’ growing from the side of the agave.

There are two different styles of the flowering stalk (inflourescence).  The paniculate, above, and the spiculate, below. You can clearly see the difference in the shape and design of the stalks.

spiculate flowering stalk from an Octopus agave

Octopus Agave (Agave vilmoriniana) I planted this agave (as a 5-gallon) in 1999 and it flowered in 2005. 

Agave Reproduce in Several Ways

Agave reproduce both by flowering (seeds) and vegetatively (bulbils & offsets).

You can read more about how agave produce offsets (pups) and how to plant them from a previous post – Pups In The Garden…Not The Soft Cuddly Kind.

Agave desmettiana flower with small bulbils growing within the flower

The flower of an Smooth Leaf Agave (Agave desmettiana) This is an agave from my garden, which was planted in 1998 and flowered in 2007.

You can see the small bulbils (baby agave) forming among the flowers above.  The bulbils will continue to grow and will receive nourishment from the stalk.  If left alone, the bulbils will eventually fall to the ground and root under ideal conditions.  They can be removed from the flowering stalk and planted, but do best if left until they have formed at least four leaves.

Early on as a horticulture student, I fell in love with Octopus Agave and I bought my first one at a plant sale.  I planted it in a large pot and it thrived.  Years later, the flowering stalk started to grow.  I was both excited and a little sad.  I was happy because it was finally achieving it’s crowning glory….and sad because I knew it would eventually die at the end after finishing it’s life’s work.

Matured agave bulbils grown into young plants

However, that is not the end of the story….my original Agave lives on.  I took two bulbils from it’s stalk and planted them (above) and they are ready to be planted out in my garden. (Actually, I could have planted them much sooner).

**Note the little seedling coming up on the left side of the pot.  My son planted the seed, but we aren’t sure what it is.  I think he might have planted an apple seed.  We shall see….

Beauty With Age….

Agave, Arizona, Succulent Gardening
beauty with age

 Artichoke Agave (Agave parryi ‘truncata’)

Our society usually doesn’t equate beauty with age.  Instead, we celebrate youthful beauty and spend our money on trying to stay looking younger than our years.  Thankfully, in the world of plants, maturity is something to be celebrated.

In the case of the agave, age equals beauty.  A leaf of an agave plant can live for up to 15 years.  The leaves are etched with beautiful patterns called ‘bud imprints.’   These delicate patterns decorate the leaves in numerous different ways depending on the species, as you can see in the photo of my Artichoke Agave (Agave parryi var. truncata) above.

 Cow’s Horn Agave (Agave bovicornuta)

Along the sides of agave leaves are small thorns, called ‘teeth.’  Agave leaves stay in bud for 2 – 3 years.  The teeth from the leaves imprint on the other leaves while they are held tightly within the bud, which is how their delicate patterns are formed.

beauty with age

Depending on the species, some bud imprints are more obvious, while others are more subtle.

The fibers from the leaves of the agave are used for weaving items such as bags and mats.  The leaves are also used to feed cattle in areas of Mexico.

 Agave ‘Durango Delight’ (Agave schidigera ‘Durango Delight’)

Some agave leaves have filaments along the edges.  Most agave end with a sharp terminal spine, which should be taken into consideration when you decide where to plant them.  You do not want them in high traffic areas where people can be pricked, (believe me, it hurts). 

beauty with age

 Mescal Ceniza (Agave colorata)

Because agave store water inside their leaves –  their leaves are thick and succulent.  Some of my favorite agave species are Artichoke Agave, Mescal Ceniza, and Victoria Agave.

Agave salmiana

 Agave salmiana

I saw this agave (above) next to my gym, and I was very impressed by its teeth.  They remind me of ‘claws.’

Beauty With Age

There are between 200 – 250 different species of agave, in all shapes, colors, and sizes.  Some of my favorite features of agave are how beautiful they are with their leaf shapes and imprints.  Secondly, their low-maintenance and drought-tolerance also make them a favorite in my garden.

Victoria Agave

 Victoria Agave (Agave victoria-reginae)

Agave is amazing plants, and I am a huge fan.  There is much more information to cover, which I will address in a future post.  But, I will answer the most common question that I am asked about agave, “No, they do not live for 100 years.”  You may be surprised at the real answer…

But, that is for a later post…
