Today I am highlighting a lesser know Texas native snapdragon vine, Maurandya antirrhiniflora. It belongs to the Scrophulariaceae family, like the common garden snapdragon. You might have guessed that from the species name being similar to antirrhinum, commonly used for snapdragons. Last year I tried to grow snapdragon vine on the trellis outside my kitchen patio. After a great start it failed miserably, but it did leave behind seeds which have germinated in several places in the garden.
It seems the vine would like to grow the way it wants to, which is by sprawling across the ground and entwining its petioles around anything in its path. Here it is prettying up the oregano. It is a delicate vine and once it has coiled its petioles around a stem there is no letting go.
A second plant I am now training onto an arched bamboo trellis, although it doesn't help to twist its stem around because that is not its method of climbing.
As I mentioned earlier it is the petiole stem that does the twisting and support as opposed to the stem itself. As a temporary hold I taped the stem to the bamboo using velcro garden tape. In the wild the flowers can be found in all shades of purple to an infrequent white.
The first time I saw this plant growing was in the garden of Pam Penick. It was twining its way up some fine wire twisted around the pole of her dovecote. This dovecote now resides in my garden but I have not been successful in getting the vine to twine up the existing wire. Maybe next year I will have success.
I shall be saving seeds this year in an attempt to ensure it grows in a more suitable place next year but undoubtedly it will show up in lots of other places too.
