wow that depends on a bunch of stuff I think. Shady or Sunny do you need drought tolerant? What colors do you like and what kind of
flowers. Some people like the different types that are
rose like (that's me) some like
flowers that are shaped like mums and daisies, some like
flowers that are trumpet shaped.
Then what does the space look like? Does it want tall
plants or miniatures, vines or single stalks or something more bushy.
Then of course it would help to know your
zone and about how much sun you have per day. And the soil temperature. I know one of the
plants that I like are celosia which need to be direct sown but they need a soil temperature of between 70 and 75 degrees.
So as you can see there are a lot of questions that need to be answered first before a good christmas list can be drawn up lol.
Of course you can start herbs just about anytime indoors and probably a lot of them could be done outside in your area.
