Basil

I planted some of it this week in containers with organic potting soil, and kept them watered.

The seeds took only two days to start sprouting.

Wow.

I guess it's easy to grow basil in Houston if you plant your seeds in late August!

Opuntia update--Unexpected aquisition.

I was telling a plant-loving friend of mine that I was thinking of trying to grow a prickly pear, when she told me I was welcome to a lobe of the "spineless" one that she has. So I took her up on it.

The thing looks pretty cute in its container. No obvious signs of new growth yet, but it doesn't look like it is rotting, either. According to this it takes a month for the new roots to form, and I only planted it a couple of weeks ago.

Unfortunately, I do not know exactly which species I have. Maybe when (and if) it gets bigger, I'll take some pictures and post them. Who knows, maybe someone will stumble across the blog and give me some ideas. :)

I can personally recommend handling these with dainty fingers (and gloves, if available). They do not have obvious spines, but they do have tiny little ones that can cause pain, and which are difficult to get out of one's skin, especially if you can't see them very well! I got one in my thumb while transplanting the pad I got from my friend, and it took some careful looking and removing!

Catnip bites the dust. Or the Gumbo. Whatever.

I planted some catnip (Nepeta cataria) outside last spring for two reasons:

One, to encourage our neighbor's free-range cat to frolic in our yard. She likes to hunt.

Two, to see what would happen.

Well the cat disappeared, and the catnip flourished for awhile, even in the black gumbo soil, growing at a dizzying rate. "Hot dog!" I thought. "And without soil amendments or a raised bed or anything!"

Then July came. Rains got heavier, sun got hotter, and the catnip started to look a little peaked.

Now it is definitely on its last legs. It is dying from the roots up, instead of from the top down, like plants usually die (and I've killed my share, believe me). I'm thinking root rot may be the primary culprit, but I'm sure the heat isn't helping.

It'll be raised beds or containers (and hopefully better luck) next time.

Book Review: Botanica

Full Title: Botanica: The Illustrated A-Z of Over 10,000 Garden Plants

This is a massive, encyclopedic volume, containing brief descriptions of almost any plant you could ever want to look up. It also has photographs of most of them. It is highly useful as a reference, and sometimes fun to browse through. When I hear of a species that I think I might like to try out, I usually look it up in this book first.

Being short, the plant descriptions give you just enough information to determine whether or not a plant might be worth growing in your garden. However, if you want detailed information on any particular plant, you will need additional resources. Other downsides include the fact that not every plant is illustrated, and there are some Texas Natives that are not listed in this volume. The information is also very general, so it is worthwhile to cross-check with other resources, especially if you live in a climate as unique as the one we have here along the Texas Coast.

Dioscorea bulbifera

Update (3-1-08): Despite the fact that the Houston Garden book lists them as an option for the garden, I checked the Texas Invasive Plants database, and discovered that this plant is on the list. Apparently Florida and Alabama aren't the only places where this plant can take over. It is also known to spread underground as well as by the builbils. This information was not in the USDA plants database at the time of this original post. Oops. :) And I still have those builbils someone gave me last August!

---------------------------------------------

Common names: Air Potato, Air Yam.
Duration: Deciduous perennial. May freeze to the ground in winter.
Nativity: South America, Africa, Australia
Light: full Sun
Ideal planting time: April
Growth rate: Fast.
Growth Habit: Vine--requires wire or string trellis for maximum growth.
Soil preference: Acidic-neutral, rich, well drained.
USDA zones: 9-11


According to the Houston Garden Book, these deciduous, fast-growing vines are easy to cultivate. Judging by the fact that I see them frequently in this region, I would venture to guess that the book is correct. They are also supposed to be pest resistant.

This plant seems to be quite at home in the tropical and Sub-tropical regions of the United States with thriving naturalized populations in Texas, Louisiana, Alabama, and Florida, as well as in Hawaii and Puerto Rico, according to the USDA Plants Database. In some places, it thrives too well, and is therefore considered a noxious and invasive weed in Florida and Alabama. It should not be planted in those states.

I recently acquired two bulbils from a very friendly person with an abundance of these (or something in the same genus) in her own Houston area garden. She likes them, and finds that they take little effort to grow. She just tosses the bulbils wherever she wants her plants to grow, and with watering, they will sprout. No digging, no burying.

I will probably start mine in containers, and find a place for them in my garden later.

Note: Dioscorea bulbifera is not edible!
