Be Gone, Begonias!


Fellow garden blogger Shirley Fox shared this photo and commented, "that shelf was intended to hold begonias! Begonias have lost their place."




I nabbed another photo of the tortoise-shell feline off her blog at https://rockoakdeer.blogspot.com where she said, "She arrived as a feral about four years ago and we began caring for her. Over time, she has become more friendly, but is still wild enough to remain an outdoor cat."

Why Do Cats Go Nuts Over Weigela?


My garden writer friend, Larry Hodgson, over at the Laidback Gardener blog (https://laidbackgardener.blog/) posted this q-and-a on a topic I had never heard of before -- some cats love weigela. I grow many kinds of weigela shrubs in my garden and have not seen any of my cats or other cats interacting with it, but I am going to keep an eye out for it now.

Here is Larry's blog post about it:

Question: My 7-year-old cat has discovered my weigela bush. During flowering, he climbs into the shrub to grab the flowers, rolls around in it and meows happily. Honestly, he seems to be high! I have many other plants, but he leaves them alone. It’s really very funny. Do you know why this happens? ~ H. Filteau

Answer: You’ve hit upon a situation that is fairly well known to cat-lovers, but one that has not yet, to my knowledge, been studied. Some cats (a small minority) do indeed seem to adore weigelas, but others are completely indifferent to these shrubs.


I think it’s safe to presume that weigelas (or at least some weigelas) give off a chemical compound of the same type as nepetalactone, the terpene that makes catnip (Nepeta cataria) so attractive to many kitties. Other nepetas (Nepeta spp.) also give off this product, but to a lesser degree. In fact, protecting ornamental nepetas against overenthusiastic kitties was the subject of a recent blog: Protecting Nepetas From Cats.

A Repellent With a Feline Side Effect
If the catnip produces nepetalactone, it’s as a protection from predatory insects. Nepetalactone is a recognized insect repellent and few six-legged pests will attack catnip plants. Its side effect, that is, attracting cats, is less desirable … for the plant at least. But cat owners have a lot of fun watching their tabbies interact with dried catnip leaves, often added to cat toys.
Similarly, some cats avidly rub up against and roll around in honeysuckles (Lonicera spp), including Tatarian honeysuckle (L. tataricum), and it also produces nepetalactone. In fact, honeysuckle shavings too are sometimes added to cat toys.

Kiwis (Actinidia spp.) produce a different product that attracts and intoxicates cats in the same way: actinidine. The silver vine kiwi or matatabi (A. polygama) is particularly rich in actinidine. In fact, in the Orient, silver vine sticks are more often used in cat toys than catnip.  
REPORT THIS AD
In my own garden, a brown and white cat often rubs against and scratches my female arctic kiwi (A. kolomikta), obviously in ecstasy. Oddly, she never touches the male vine. Maybe my female cultivar, ‘Ananasnaya’, is richer in actinidine than the male? Curiously, other cats in the neighborhood seem indifferent to both.

Valerian (Valeriana officinalis), an ornamental perennial, medicinal plant and, in many areas, noxious weed, also produces actinidine and will also attract cats.
Finally, cat thyme (Teucrium marum) produces another component that makes cats go a bit nuts: dolicholactone, chemically very close to nepetalactone. It’s occasionally grown as a cat plant.

How cats respond to these various products differs from one individual to another. Some only react to nepetalactone, others only to actinidine and others only to dolicholactone, others to two or all three and finally, some cats simply don’t gain any euphoric effect from plants of any kind. Also, the reaction can also vary depending on the conditions: for example, some female cats don’t react to these products during pregnancy, but resume once their kittens are born.
Now what we need is a scientific study of exactly what compound in weigelas attract cats… and then I’ll have an appropriate answer to your question!

Hachi: A Cat's Tale

Hachi reacts with consternation to my meowing at him.
 Inez Austin Jackson and I are both members of the Potomac Rose Society and a few other local garden clubs. Over the years, I have heard amazing things about her garden and legendary hospitality, so I eagerly anticipated attending her open garden a few weeks ago. What I had not been told about was her beautiful garden cat. This stunner came out the greet me as I took numerous photos around her garden. He was a terrific and playful tour guide.

She writes, "His name is Hachi. He is an Ocicat breed. He is extremely loving and friendly to others but an avid hunter. Keeps after the chipmunks and has rid the garden of moles, voles, and mice. When he isn’t busy hunting, he loves to ride around with me in the car on errands. 
  The little box on his collar keeps him as a house and garden cat. Otherwise, he would be over the fence- hunted and eaten by the many, many foxes in the neighborhood."

Why are all these insane plant people in my garden?

Pet me, please!

Those gorgeous hunter eyes,

Hachi accepts stranger's kisses.
