Desert Flowers

Desert Flowers

Desert plants have learned to live in extreme conditions.  Their flowering techniques are very unique and colorful. 

Cactus

 It is estimated that there are 1000-2000 types of cactus and that most are native to North America. 

They grow in sandy soil.  The main error of homeowners is to not plant them in soil that drains well enough and the roots will rot.  In addition, they can occasionally be infested with bugs like aphids, spider mites and mealy bugs.  One solution is to mix a lemon scented Dawn with water and spray the plant.  You can also buy insecticidal soaps at the nursery.

Cactus usually bloom white, red, or pink.  Here is a good link to tell you all about cactus.

Penstemon – Bearded Tongue

These flowers are dainty and usually red; but can also come in white and blue.  Nurseries carry many varieties. Some are good for rock gardens, while others make a good border. In any case, they need room.  They don’t like to be overcrowded.  They can tolerate full sun, but prefer partial shade.

There are thousands of varieties.  You could write several books about them because there is so much variety.    

Penstemons are a favorite for those who love dainty flowrs.  Here is a website that will tell you everything about them.  In fact, you can find informationon how to join the National Penstemon Society  http://www.biosci.ohio-state.edu/~awolfe/Penstemon/Penstemon.html  If you join the society, you can become part of an exclusive penstemon seed exchange.
