Rock spirea (Holodiscus dumosus) is a very drought tolerant native shrub reaching 6’ in height and width. It has fragrant leaves (when brushed against) and it produces sprays of small, white flowers at the ends of arching branches. After the flowers fade, the seeds are also ornamental, producing pinkish seed heads. Rock Spirea does best in full sun to half shade and may decline if watered too much.
You can often find it growing in its native habitat in the mountains west of Cheyenne.
There are many different types of basil you can grow. There are varieties with smooth, crinkled or ruffled leaves and some with purple foliage. There is a little leaf, dwarf basil and varieties that smell like cinnamon, clove, lemon, lime and licorice. The most widely grown basil for culinary use is Italian basil such as “Genovese.”
Basil likes it warm so wait to set plants out in early June. Regularly pinch the tips to get a bushy plant and always prune flower stalks. Basil is best used fresh as dried basil loses most of its flavor. It can also be frozen for storage.
Now is the perfect time to do some important maintenance to your clumps of ornamental grasses. Because these grasses are about to start growing again, it is a good practice to prune each clump down to a height of 10” so that the new growth is not interspersed with the dead brown grass blades from last season.
A fast, easy way to cut the ornamental grass is with a small folding pruning saw . Use the cut grass as a mulch on your perennial bed or add to the compost pile. The most dependable ornamental grasses you can grow on the High Plains include Karl Forester (all types), blue oat grass and blue fescue.

Starting as of April 1, the Summer City Yard Waste Program will resume for the season. Those residents enrolled in the program will have their yard waste containers picked up the week starting on Monday, March 31. Billing will start on April 1. The program ends mid-November. Program users are reminded only grass, leaves and garden waste are allowed in the yard waste container.
Customers are reminded not to bag the material, and to not place large branches, limbs or brush in the yard waste container because bulky items prevent the container from being emptied. The Yard Waste Program is currently not accepting new customers because staff and equipment limitations.
For more information on the program, call the Sanitation Division at 307−637−6440.

These dwarf irises come every year with little care and they each year they come back more plentiful than before. They bloom through the unpredictable weather of spring and do fine in the snow and cold of early to late March. They can be planted in a lawn (even dandelion killer won’t hurt them) or a in bed. These dwarf iris go by the fancy name of “Iris reticulata,” for the bluish/purple ones and “Iris danfordiae,” for the yellow ones. They’re among the first to bring color to the garden at the beginning of spring.
They come from small bulbs planted in late summer or early fall and you can often find them sold as a mixture of yellow, blue, dark purple and light blue. Look closely at the bluish shades and you’ll see an intricate little pattern that attracts bees like a lit airplane runway.
If you had planted the bulb, ‘snow drop,’ in a sunny spot in your yard. You would have blooms today.
The snowdrop flower that comes from a small bulb is always the first flower to bloom in High Plains gardens (usually you see the first flower in mid-February through early March), even under a blanket of snow. While it is quite small, looking like three drops of milk hanging from a stem, it does wonders for the spirit when it blooms in the snow. It’s Latin name is appropriately “Galanthus” which means “milk-white flowers.”
These are not common bulbs to find but most good garden centers will carry snowdrops. They are also readily available via mail order. They are commonly sold in the Fall and should be planted prior to winter setting in. Make a note on your calendar now for to purchase them in late September. They bloom best and earliest in a sunny location.
The next flower to bloom in Cheyenne will be the early dwarf Iris reticulata (blue) and Iris danfordiae (yellow).
It is the time of year when the seed catalogs arrive. What are your favorite catalogs and does it make sense to do mail order or just buy seeds at the hardware store?
We would urge you to order seeds from catalogs because it gives you much more in the way of choices. For instance you might find one early tomato variety on a seed rack and five choices in a catalog. Here are a few of our favorite catalogs that are worth considering: for flower and vegetable seeds, try Johnny’s Seeds (www.johnnyseeds.com), (more…)
If you have an interest in medicinal, culinary or useful herb plants, seeds or books, you can’t do any better than Richters herb catalog. There you will find an extensive listing of both common and unusual herbs. For instance they offer over 40 different types of basil. (more…)
True orange petunias are rare until now. The new petunia variety “African Sunset” wowed the judges of the All American Selection organization. They found the African Sunset petunia to be superior to similar colored petunias currently available. Gardeners are always looking for a petunia that grows evenly and uniformly in the garden while producing a prolific number of blooms all season-long and this beauty certainly fills that need. (more…)
