Drought tolerant , Z5 perennial 6-8" tall ???
The last 2 Summers we have had unusually long periods of hot dry conditions. I am sure that is the story in many parts of the US. I have 2 raised cinder block (2 blocks high), enclosed beds in the front of the house. It is filled with 32 Daylilies of red, white and pink. With the heat and drought they are not increasing as fast as they could. I need a perennial to mix in with them to fill out the bed, hold the moisture and hold the fort so to speak when the Daylilies are done. Daylilies are not the most attractive when the flowering season is over. The beds are 5 years old. I have tried Lambs Ears,(too invasive they try to smoother the DLs) Penstemon mystica,(did too well, huge and overpowering ) Hosta, ( burnt, even though " sun tolerant" variety) The plant dose not need to flower but should have a different color and texture then the grass green DL foliage. If it flowers it should be a red, white, pink or blue/purple. A very pale yellow would be OK too. Am I asking too much. Is there an annual that would be a better fit. Do I need to surrender to the annuals? Help! It would be greatly appreciated.
