Beach Morning Glory

Beach Morning Glory (Calystegia soldanella)

Well, morning glory is not a glamorous plant but it is easy to identify, at least the beach variety. It has big pale lavender bell-shaped flowers with white streaks inside them and round leaves. Morning glory's Latin name is Calystegia soldanella, also known as Convolvulus soldanella. Note that even  botanists can't tell the difference between Calystegia and Convolvulus genera without microscope and sometimes they are grouped together. The difference is so minor that we do not need concern ourselves.

Calystegia is a Greeek word and means "a covering cup", referring to the cup-like shape of the flowers.  Convolvulus is a Latin word derived from the word convolvere, which mean to "wind" and refers to winding stems of the plants within the family. It is a vine. Morning glory, also known as bindweed makes a nice decorative plant that does not take any maintenance. Though commonly seen flowers are usually white or very pale, some species come in gorgeous bright colors, like for example dwarf morning glory (Convolvulus tricolor).

Well, as the name implies, this plant belongs to Morning glory family known as Convolvulaceae.

By the way if you ever decide to photograph beach plants, don't be surprised as the amount of insects getting in your pictures. Little bugs love these plants. Well, with the flowers like this it has to be insect-pollinated, but I think the pollinating insects are ants and beach bugs rather than bees.

Beach Knotweed

Beach Knotweed (Polygonum paronychia) is one of the common plants that can be seen on the beach among the dunes. This plant is fairly easy to identify by its narrow green leaves and small white flowers. The blooming season lasts at least a month, perhaps more.

As the Latin name suggests, the plant is part of the Knotweed family (Polygonaceae) so look for the swollen or distinctive joints along the stem. The flowers are not the spike like lots of other genera but rather distinctive small white flowers.

Searocket

Searocket. Notice the similarity to wild radish flowers.

Searocket (Cakile maritima) is another plant that can be seen among the dunes. It belongs to the Mustard family (Brassicaceae) as can be seen by its flower: notice the similarity to mustard and radish flowers. The flowers of searocket are small and pale mauve. As typical for other mustards, the mature plant produces pods.

Note. The big leaves in two pictures actually belong to a different plant, Ambrosia chamissonis. But the leaves of searocket look very similar albeit much smaller. You can see some on the picture above. See my post about Ambrosia chamissonis.

Here is the picture of searocket leaves:

Yellow Sand Verbena

Abronia latifolia on the beach

Let us leave the garden and take a walk on a beach. Dune habitat has its own plant life and although it might not be as exuberant and exciting as the forest or meadow, nevertheless there are some unique species there that are not found anywhere else. Usually these plant have "dune" or "beach" or "sand" as part of their common name. Sometimes it is a species peculiar to beach habitat wherefore other species of the same genus strive in different environment. An example of such a plant would be morning glory. It grows pretty much everywhere where thee is enough sunshine and moisture. The genus species in Latin is called Calystegia. There are quite a few. The most common species is Calystegia sepium. The beach morning glory species is Calystegia soldanella.

With verbena things are getting hairy. First of all, the common name verbena has nothing to do with the genus named Verbena (it's the Latin name too) which is part of the Verbenaceae family. Sand verbena in Latin is called Abronia and the yellow variety that we are interested in is called Abronia latifolia. (Latifolia means "with broad leaves".) Our friend arbonia belongs to Four O'Clock Family (Nyctaginaceae)

The flowers of Abronia latifolia are arranged in neat round heads. The leaves are succulent but rough to the touch. It can be seen on the beaches and dune habitat but the plant is not very common.

Nigella

Nigella

Nigella is an interesting garden plant that has a very distinctive appearance. The leaves are dill-like. The flowers are rather big, blue with a big protruding middle part with tentacle-like filaments (stamens?). I see it occasionally on the curbsides.

The seeds in some varieties are edible and known as black cumin or onion seeds (yeah, I know). Though the name cumin can refers to a couple of other plants. Nigella seeds are widely used in Indian cuisine.

Nigella is easy to grow in the garden. The plant is self seeding.

Nigella is part of the buttercup family (Ranunculaceae).

Blue Star Creeper

I don't know how "wild" Blue Star Creeper plant is but so far I only saw it at the curbs and on some neglected looking lawns. I did some research about it and found out it's actually quite valuable garden/lawn plant, especially valued for its tolerance to be walked upon (like camomile) and therefore can be planted in cracks between stone slabs, tiles, pathways or wherever else you want to have flowers rather then dirt. The plant is very low growing (a creeper), the pale blue flowers are small but bright and cheerful and they certainly catch the eye.

Here is the picture of that curb:

And a little more close (notice the yellow spot in the middle):

And here is the picture of the single plant in a profile. It is rather small, about the length of a finger though on the ground it seems much shorter:

Blue Star Creeper

 Blue Star Creeper's Latin name is Isotoma fluviatilis. It belong to the family Campanulaceae. I don't know why, it certainly does not look like a bell flower to me but we leave the nomenclature to the botanists.

This flower can bloom for a long time until the frost gets it so it's perfect for permanent warm climate. Here it does not bloom in winters.

Gilia millefoliata

Gilia is a very small and inconspicuous plant that grows in meadows. There are several species in the genus, the one we'll look at today is called Gilia millefoliata, which translates literally as "thousand leaves" gilia. It grows in sand dunes habitat along the coastlines. The flowers are usually blue but very small though the stem can reach 5 or more inches. The stems are fuzzy. The leaves are similar to yarrow leaves. In fact common yarrow is known as Achillea millefolium.

Gilia is part of the phlox family (Polemoniaceae), together with such genera as polemonium (Jacob's ladder) and phlox. Do not confuse phlox with flax, which belongs to a different family (Linaceae).

Some time ago we went to plant exhibit and there were among others various species of phlox family. Well, one can hardly tell them apart. Just looking through my archives, there were such species as linanthus, collomia, phlox, the only difference being that some flowers were pink and some were white. I was not able to find any of them in the wild to give you pictures.

But we do have some good pictures of gilia. So here goes:

And just for fun along the same trail I happened to notice some yarrow so you can see the similarity in leaves. Millefoliata in gilia obviously does not apply to petals as there are only five of them therefore it must refer to pinnate (feather-like) leaves.
