Gardener's Glossary (an occasional series)

Guttation

     Today's word for your gardener's glossary is guttation.  Guttation is sometimes seen on houseplants or potted plants (at least, that is where I have most often seen it), but can also occur to plants growing outdoors.  Ever see water droplets repeatedly form on leaves, usually at the tip, and drip off?  And I don't mean from rain or overhead watering: guttation occurs when a plant has been overwatered and it is trying to rid itself of excess moisture.  I was drawing a potted voodoo lily this summer and noticed guttation. Sure enough, the plant later collapsed and I discovered that the bulb was rotted, in too-damp soil.  I guess I loved it to death and over-watered it.  
     If you see guttation happening, stop watering the plant, as the soil is likely too wet for that species.  In a potted plant, you may be able to poke a rag or piece of thick yarn into the soil, draping it over the side of the pot, to act as a wick and draw off the water.  Or, place the pot directly on a old towel that has been folded a few times to draw off water.  If the plant is in the ground, stop watering it.  If the guttation is due to lots of rain, cross your fingers and hope for dry weather. If the plant is in a spot that is regularly wet, it might be time to transplant it.
Happy gardening!

Wednesday Lagniappe: Gardeners' Glossary

Spur
A spur is a hollow sack, sometimes a spike, often tube shaped, in a blossom.  Spurs often carry nectar and are, therefore, considered "nectariferous" (another nifty word to work into a conversation!)
See the spurs on this "Giant Spurred Columbine?"

Wednesday Lagniappe: Gardener's Glossary Goes Underground

Bearded Iris: grows from a rhizome.

What is the difference between these terms:  bulb, corm, rhizome and tuber?  We all use these terms, but what do they mean?  How do you tell the difference between them?

Bulb: an upright, underground stem with overlapping, fleshy sales (think onion, tulip).
Corm: Underground stem with no overlapping scales OR very few scales (think crocus, gladiolus)
Rhizome:  a scaly underground stem (think bearded iris or canna)
Tuber: modified underground stem produced at the tip of a rhizome (think white or sweet potato).

Happy gardening!

Wednesday Lagniappe: Gardener's Glossary- NOT!

I am reading a book of garden essays (Thomas Cooper, The Roots of My Obsession) in which famous gardeners describe why they garden.  It is fun and resonates a lot with me.  And here is a word from one essay:

"Yardening": Being "driven by a desire to keep a tidy landscape or to one-up their neighbors" (Ken Druse "Island Life," p. 77, in the above book).  It is not why Druse nor I garden, but it is so true!

Happy Gardening!  Not Yardening!

Wenesday Lagniappe: Gardener's Glossary


"Tetraploid"

Have you ever heard of a plant described as a tetrapoid? This means it is an organism with twice the number of normal genes.  Tetraploid plants can be more vigorous, with larger blooms. They can be created by using colchicine, a derivative of the autumn crocus, to double the chromosomes, or can occur spontaneously.  Commercial daylilies are often tetraploids (44 instead of 22 chromosomes).
Happy gardening!

Wednesday Lagniappe: Gardeners' Glossary

Here is another useful garden term:  Apical:  Located at the tip of a leaf, root or shoot.  Some plants will not be able to grow if their apex is damaged or cut off, or they will have multiple sprouts if that happens.  The opposite of apical is basal, at the base, and both are different from lateral for the side, as in a side shoot.

Impress your friends! Now you can describe your plants using these terms, as is "the apical bud was snapped off in an ice storm" or "this biennial forms a basal rosette in its first year."
Happy gardening!

Wednesday Lagniappe*: Gardeners' Glossary**

Today, a word that is one my favorite gardening terms:
Allelopathy:  is the reason you cannot grow some plants under walnut trees.  Allelopathic plants are those that secrete a chemical compound that inhibits the growth of another plant.  In walnuts, this substance is juglone.  However, some plants are allelopathy-resistant or unaffected.  It is recognized that these plants can grow under a walnut just fine:  blackberries, grapes, mints, forsythia, ferns, marigolds and most native hardwoods! Eucalyptus, alianthus ("tree of heaven"), garlic mustard, rice, fragrant sumac, and hackberry are other plants with allelopathic properties.

* Lagniappe:  Cajun for "a little something extra."
