Whatz that? - Barstow groundcovers

What exactly are groundcovers?  In this posting, I am taking them to be plants that are small enough to walk on or to step across, plants that in general are wider than they are tall, or that expand and form low mounds that are less than 18" high.  I am excluding from this category those grasses that are commonly used for lawns.  I am also excluding low growing annuals and perennials that do not have time to expand and cover much ground, and such plants as low growing cacti.  This list includes those groundcovers that the New Sunset Western Garden Book identifies as appropriate for Sunset zone 11.  The pictures are of those growing in my yard.

Common Yarrow/Achillea millefolium, xeric, white flowers, green all year, bears light foot traffic









Aloe/Aloe sp., xeric, needs shelter in Barstow
I do not know which particular aloe this is, however I like it as it spreads rapidly into a groundcover.

Alyssum/Lobularia maritima formerly Alyssum maritima, xeric, white flowers most of the year
This is an annual, but it reseeds freely enough to cover the ground.
The purple variety quickly reverts to white.





Roman Camomile/Chamaemilium nobilis formerly Anthemis nobilis, moderate water, used for herbal tea
This plant is too scraggly and too short lived to make a good groundcover.  However it has the advantage of reseeding freely.








Ice Plant/Carpobrotus chilensis, xeric, marginal for Barstow







Dwarf Plumbago/Ceratostigma plumbaginoides, moderate water, small blue flowers in summer, partial shade









Rock Spray Cotoneaster/Cotoneaster horizontalis, xeric, not deciduous. small white flowers, red berries in winter
Can be trimmed to be nearly flat.
Unlike its cousin Pyracantha, Cotoneaster does not have thorns.
Ice Plant/Delospermum cooperi, purple flowers, xeric
Spreads to form a mat.







Dichondra/Dichondra micrantha, regular water, marginal in Barstow, looks better in partial shade, can take foot traffic







Winter Creeper/Euonyous fortunei, regular water, partial to full shade, white heart-shaped flowers with red berries
This plant is a vine which can be grown as a groundcover by trimming it back when it starts to climb a wall.
The branches take root and spread.  In a colder climate, the leaves turn red in the Fall, but not in my yard where it is in a sheltered location.

Rosemary/Rosmarinus officionalis is very xeric and reseeds.  Trailing varieties form mounding plants that can be trimmed to be nearly flat.






Yellow Creeping Jasmine/Jasminum nudiflorum, xeric, deciduous, flowers appear before leaves,
more a low sprawling shrub than a groundcover







Carpet Juniper/Juniperus horizontalis, evergreen, xeric
This particular plant has not been in the ground very long.  It would be larger than it is if I gave it more fertilizer.





Lantana/Lantana montevidensis, moderate water, bright colored clusters of flowers all summer, dies back in winter, berries are poisonous
Be sure to get the groundcover variety.

Blackfoot Daisy/Melampodium leucanthum, moderate water
I have this plant on a xeric drip system.  Maybe that is why it is more a straggly flowering plant than it is a groundcover.







Mexican Evening Primrose/Oenothera speciosa formerly Oenothera berlanderii, xeric, sun or partial shade, blooms all summer










Shamrock/Oxalis acetosella, regular water, partial to full shade, pink flowers,
Dies back after blooming, therefore I do not have a picture right now.  Shamrocks are related to the invasive week, Oxalis, but they are not invasive.

Purple Shamrock/Oxalis regnelli, regular water, partial to full shade, white flowers
Dies back after blooming.






Purslane/Portulaca oleracea, regular water, very small yellow flowers
I bought a large-leafed variety for my herb garden, but it didn't like it there.  It reseeded freely in the lawn and I have allowed it to grow because the stems and leaves are edible.  They add a lemony flavor to salads and cooked dishes.  It is considered invasive.

Rose/Rosa, groundcover varieties
These are more nearly sprawling shrubs than they are groundcovers.








 
Biting Sedum/Sedum sediforme, xeric

Reseeds freely, also spreads through rooting of stems.  The flowers are not attractive and when the flowers die, the dried flower stems have sharp edges.








Angelita Daisy/Tetraneuris acaulis formerly Hmenoxys acaulis, xeric, yellow flowers
Forms a slow growing grass-like mat
Verbena/Verbena, xeric, small purple flowers most of the year, reseeds freely

  1. Where can I find trailing rosemary in Barstow?

  2. Trailing rosemary usually isn't available in Barstow. Try online or at Oak Hills Nursery on Ranchero in Hesperia.

  3. Thanks. I haven't been actively looking for nurseries, and the rosemary I currently have I bought at Home Depot. It is doing great, but it is also apparent to me that it is not the variety I see everywhere as ground cover. The people at Home Depot really didn't know anything, and they answered my questions by reading the side of the plant container that I was holding in my hand. I'm really new at the gardening gig, but I think that the nurseries are probably the much better place to go.
