Question
Hello Sir,

I have about 25 feet of walkway to my front entrance. On the border, I planted a mini rose followed by an agapanthus, using this pattern through out the whole 25 feet. So there is 6 Agapanthus and 6 mini roses. I later found out that the watering schedule for these plants are different, the mini roses need more watering.

Can you please suggest some replacement perrenials with flower that can compliment the agapanthus and have similar water needs?

Thank you,

Will

Answer
Hi Will,
I'm sorry it has taken so long to get back with you.  I had a death in the family and I just took off to get things settled.  So please accept my apologies and I hope there was not too much inconvenience.

Here is a listing of top drought tolerant perennial flowers for California.  I might also recommend lantana, bird of paradise, aloe, agave, various types of cacti, African lily, crocosmia.  Here's a link for others.  I hope this helps.
Tom
