Layout

Since the boxes sit side by side, they read as one ~8-foot display. The design flows as a warm-to-cool gradient — oranges and yellows on the left, transitioning to purples and blues on the right. Taller plants go toward the fence, shorter ones face the street.

Spring action plan

1
This week — Call ahead Contact Delta Flora, Pelican Greenhouse, or Harold's Plants and ask what's in stock. Specifically ask for Gulf Coast Penstemon and Wild Blue Phlox — these are your "instant spring color" plants and they sell out fast.
2
This week — Buy supplies Pick up potting mix (4–5 bags of 1.5 cu ft, like FoxFarm Ocean Forest or Miracle-Gro Performance Organics), a bag of compost, and a bale of pine straw mulch. Grab transplants for everything available — Firewheel and Black-Eyed Susan are at every nursery.
3
Mid-March — Fill & plant Potting mix in both boxes, plant according to the layout (tall in back near fence, short in front). Water deeply after planting, then fill the self-watering reservoir completely. Top with 1" of pine straw mulch.
4
What you'll see By late March: Phlox and Penstemon blooming in Box 2. By mid-April: Firewheel and Coreopsis join in. By June: everything is going — full display through fall.

Care guide

Watering

The self-watering reservoir does most of the work. Check and refill weekly. In peak summer (July–August), check every 3–4 days.

Fertilizer

One application of slow-release organic fertilizer (Espoma Plant-tone) in early March when you plant. That's it for the year.

Deadheading

Snip spent Firewheel, Black-Eyed Susan, and Coneflower blooms to keep new ones coming. Leave Coneflower seedheads up after October for winter birds.

Winter

Butterfly Weed and Blazing Star die back completely — they'll return from the roots in spring. Don't pull them out thinking they're dead.
