The Q&A Archives: Larspur-annual or perrenial

Question: I bought 8 larspur plants (Vigoro) from Home Depot and planted them around my pool. I bought them specifically because they were in the Perennial section, and the tag on each says

Answer: Larkspur (Consolida ambigua) is an annual, although it is sometimes grown as a biennial meaning it is seeded in the fall for blooms the following spring or early summer. You may find that your plants self seed to grow a self perpetuating patch from year to year so they seem almost like perennials. To encourage this, stop deadheading and allow them to set seed, and do not mulch over top of the fallen seeds. There is a closely related plant, Delphinium, that is a perennial. However, delphiniums are very difficult to grow as a rule and are not reliable garden plants in your climate. I wish I could be more encouraging.
