Seed of the Week: Cat’s Claw Vine

Our mystery seeds from last week were from a cat's claw vine with the awesome scientific name, Macfadyena unguis-cati.

Cat's claw vines are commonly seen growing on houses and walls throughout the desert Southwest. The plants are able to tolerate the high heat of these exposed locations.

The vines are called cat's claw because of the their distinctive three-segmented tendrils that will tenaciously latch onto a surface. The ends of the tendrils are curved, like a cat's claw.

Many people grow these plants for their bright yellow, tubular flowers.  (I will add a photograph later, as the day after I decided to feature this plant last week all the flowers dropped off).

The flowers develop into long brown beans that are filled with these winged seeds.

The plants will grow from seeds, as well as cuttings. They also form a tuber under ground.

Once you plant them, cat's claw vines can be very difficult to get rid of. In Florida they are on the invasive weed list.

Do cat's claw vines grow where you live?

    I have planted these seeds twice so far. Once with bottom heat and once without heat, not one seed has germinated. What am i doing wrong? South coast, uk.

    Tina,

    Cat's claw vines like heat to germinate. They can take up to 3 months. Were your seed pods brown (mature) and the seeds fully dried? Also, don't bury them too deeply.

    Just a note: these vines are highly aggressive and hard to remove once they are started. Be very careful where you plant them.

    Hi Roberta,
    Many thanks for the advice. Yes the seeds are fully ripe and from a reputable company. I still have some so will try again. I think i was too eager and didn't wait long enough. Once again, many thanks,
    Tina.
