Well i work at Lowe's here in Tx in the garden center so i suppose i should know this however i'am the waterer there and not the plant specialist and i haven't gotten around to asking her this question. I could read the tag but i've come to find the tag is not the most reliable resource. So why not ask the experts?? I see alot of people asking for and buying Salvia Greggii. My question is ....How hardy is it??? I buy very little any more that i cannot at least hope to see come back up in the spring. Here in West Central TX we can expect to drop below 20 degrees a few times each winter. No snow for insulation and the cold usually blows in with a cold front and out a day or two later, never hangs around long. What do you think??
