Question: I see purple crocus-like flowers in a few yards near my home. Doesn't crocus bloom in the spring?
Answer:There is a crocus  that blooms in the fall. It i.s related to the one that blooms in the spring. Fall blooming crocus is crocus sativus.It is the crocus that produces saffron, the most expensive spice in the grocery store. The orange-red stigma is the part used as  a spice but, it  takes several thousand stigmas to make a pound of saffron. If you don't care for saffron, you can plant  the bulbs for their lovely blue color since there isn't much color at this time of the year. 

Question: I am having trouble choosing a grass for a lawn. Can you give me the options?
Answer: The major divisions of grass for Northwest Arkansas are Bermuda grass and fescue. Bermudagrass is a warm season grass. It turns green around April-May and dies out in October. It  best in full sun. It is invasive, this matters if you have flower beds.
Fescue is a cool season grass. It greens up in March and unless it is watered, it goes dormant in mid summer and returns  to green in September and lasts until a hard  frost.
Northwest Arkansas is what is called a traditional zone. This means that summer in Arkansas is too hot for cool season  grasses to perform well and winters are often cold enough to injure or kill warm season  grasses.
The Extension Office  of Washington County has  much more information on choosing and maintaining a  lawn. It is free for the asking.

Answer: Lilies should be planted when the ground has cooled off. Now, and until a hard freeze is about right.Lillies should be planted 4 to 6 inches below the soil surface.  If you are planting the Asiatic type, they should be planted 8 inches below the soil surface. As an extra protection  they will fare better under a protective layer of winter mulch.
